    Stuff from the Peavey/Crest auction

    My modded one has a step down converter so it can use a 12v Noctua fan. Fan is running full tilt but much quieter. if needed I can adjust it lower but I don’t find running it at 12v to have anywhere near a loud fan sound so I left it alone. It ran 4 of my JBL 1214s with ease for about a year. Its running my Mission 602 bookies in my garage right now and will eventually run a sub there instead...

    Small yet Mighty. The tale of the 12's

    Foreword: I'm a guy who likes to go into detail. The devil and the beauty is in the details, small and large. The backstory in my mind is always important as it sets the stage for what's to come and to provide insight into why certain choices were made. This thread will, like all my others, be a slow burn. My builds are intentional. They progress slowly, after much internal angst and debate, complicated by my insane need to account for all variables, and over-complicate things :). Chapter 1: The Quest is born, and a Champion emerges from the forge! The Quest I fit in well here. I love BASS. I've been to a awesome theater in Chicago twice and each time I left wishing I could get 1/10th the sound hes getting. Then I made the mistake of visiting "The Savoy", where I confirmed the reality lived up to the hype. It didn’t help. On my bucket list is visiting Luke, and attending some of the other GTG's that happen out Iowa/MN way. All these guys have SPECTACULAR dedicated theaters. I dont. I console myself with the fact that we are in the top 1% of basshead crazy, but those guys I mentioned above…. They are the 1%, OF THE 1%. My wife is not a Basshead. If you look at the threads I've posted over the years, you will see I've thrown just about EVERY idea at the wall trying to emulate most of you guys. None stuck………. In late October of 2017, we visited my good friend in Iowa. He's a fellow bass nut, and we get along great. He was using 3 SVS cylinder subs with his JTR Triple 8's. While visiting my wife commented that she LIKED (or could tolerate more) the SVS cylinders. Wasting no time, I got her to agree to allow me to copy his layout, and keep the nearfield sub that is hidden behind our sectional. In return I had to sell my UM18 first, and self-fund the build. A deal was made. The QUEST HAD BEGUN! A CHAMPION IS FORGED I had acquired 2 backup Infinity's for my nearfield sub. I researched the SVS PC-12NSD to get its dimensions and port tuning. I then attempted to emulate it in WinISD using the Infinity 1260/1262. The Infinity modeled well in a 16" in diameter 32" tall Sonotube ported to about 19 Hz. Port velocity was in check, with decent SPL. The ports fit, barely, but it would work. . All that was left was to buy another driver. Unfortunately for me, I was BEYOND LATE to the Infinity party. The drivers were long since out of stock, so I had to find one on the interwebz. They showed up on eBay, but they were around 100 bucks or more after shipping. I decided to keep waiting. I started looking for other options and remembered the JBL CS1214. The ONLY issue was, after throwing it into WinISD, the drivers only modeled close in a SEALED box. SPL response was ALMOST identical with the JBL having more power handling. In a ported box the JBL looked HORRIBLE. It needed a box that was 2x the size of the one for the Infinity. So I pushed it aside and kept looking for Infinity drivers waiting for a bargain. All your Subz belong to us! It's now a week or two before Black Friday 2017. My UM18 had sold, and I was sitting on money waiting for the right Infinity to buy. I had my parts list ready to buy for the ported Sonotubes, but was waiting till I had my last sub in hand. Someone posted the JBL CX1200 was on sale for 45 bucks at BestBuy on Black Friday. The T/S parameters were identical to the CS1214. Knowing the CX1200 was the "updated" CS1214, I wondered what the CS1214 was going for now. A quick google search turned up the fact that Sonic Electronix had them on closeout for 25 DOLLARS….. INCLUDING SHIPPING!!!!!!!!!!!!! Consulting WinISD showed that a dual opposed 1214 build would make things simpler, and not lose too much SPL wise. I could ignore worries about port chuffing, I could add a shelf filter to boost response. This became a very viable option. It helped that one CS1214 wasn't too much more than the cost of the ports for each build. And they were NEW! I am a horrible person :)[emoji33]:p. Ryan will openly tell you this. Owning that fact, I told no one but my closest friends the deal I'd found, wanting to keep it all to myself. Like Gollum with the one ring. Mine, my own…. My precioussssssss The deal I was getting started to consume me. I started with 6 drivers in my cart. This was the minimum I needed to finish 3 DO Sonotubes. The JBL's and Infinity's would work together, so no need to go overboard ...................……..But I got sub drunk. 6 became 8, so I'd have 2 extras. Consumed by greed, 8 became 12 (so I could replace the 1260's and be using all JBLs). My cart suddenly showed 12 items. Then I did the unthinkable. My finger of its own accord moved before my brain even registered. "Submit" Looking at my invoice, I felt dirty. I pictured the face of the stock boy readying my order, seeing what I'd bought, and then how little it had cost me. His face turning to a grimace seeing their shipping costs. After shipping, I doubt they made a dime I thought that was the end. I was wrong. A few days pass and I am still consumed by the need to buy more of these drivers. It was only compounded by my fear I didn't have enough extras. To the Internet! By now, word of the deal had spread and Sonic Electronix was sold out (I'd like to think because I bought them out [emoji3]). That left Amazon, where they were 65 bucks new, no longer a screaming deal. I monitored the site, and a day later two drivers showed in their "Amazon Warehouse Deals" (I think thats what its called). These were Amazon returns that still worked but had damage to the packaging, or the person just didn’t want them. 32 bucks a pop. I could stomach that. Ordered. They were mine. My total was now up to 14 subs [emoji33]. But the beast inside me was not yet appeased. I stumbled across a post from a buddy saying he had 2 drivers from testing, in factory boxes, he was selling. The post was stale, but I never saw any follow-up. I was going to be in Chicago for something else, and may as well add 2 more subs to my collection. A few weeks later the deal was done and I was on my way home with an additional 2. My bloodlust ended. With 16 drivers, there was no more room at the inn. I had already moved 8 of them to a friend's house for him to help me build the Sonotubes. That still left me with 8 at the house. It was time to start actually getting ready to build something [emoji33]. P.S. Here is a my floor plan showing sub locations.

    Stereo Integrity SHS-24 Testing & Discussion

    Looking forward to your testing on this beast..... I've always been shocked at the performance of these drivers. Wish I could fit 21's or 24's in my space (without needing a divorce lawyer, or contractor to build a bump out for my family room)

    Small yet Mighty. The tale of the 12's

    Yes. I took a TON of measurements once I got the distances locked in earlier last week. I took measurements at the following locations: Armrest (far right side), middle of the outer cushion, between the middle cushion and outer cushion, the center of the middle cushion, and lastly between the middle cushion and the center of the sectional. I measured (but didnt use in the average) the dead center of the sectional, but threw it out of the mix because its literally less than a foot away from one of the subs so the response will be crappy no matter what I do there. The image below will help better explain what I mean in case its not clear. The ones with X in them were taken but NOT used in the averages. *Note* the Sonotubes (up front) are NOT yet in play. I took 3 groupings of those measurements at different distances in the room. One close to the back, one in the middle of the cushion, and one in front of the seats. I then averaged all those measurements and used that average to generate the REW filters I've used (the fact the picture says REW 9 filters indicates it my 9th iteration* of filters I'm trying lol). Once I install a new set of filters in the Mini I then redo XT32, (measuring the subs as a single combined unit) and run the same set of measurements again to get an UPDATED average measurement across that same grouping (show in the picture in green). Then I added boosts until the response looked decent and ran those exact same locations AGAIN to get my LAST average (shown in the picture in tan). *Each time I redo the setup I learn a bit more. This time I decided to NOT cut down the top end nearly as much as I was and simply boost the low end to even it up. @Ricci If you want me to I can zip them and send them to you to look at. I'm not going to say I fully understand REW and what its telling me (outside the fact I have some long decay in the waterfall graphs and I think distortion is much higher than I'd like *as a result of my boost obviously*).

    Latest REW sweep... like this a LOT more...

    Small yet Mighty. The tale of the 12's

    I’m pretty happy with XT32.... just tired of redoing it once a day lol. Once I’m happy with the sub sweeps with the filters then I will redo XT32...

    Small yet Mighty. The tale of the 12's

    I have no idea if the MiniDSP scan do a Linkwitz transform..... I will take a look. It’s a 5.5 cf box (so maybe 5.0 after bracing and drivers).... with 4 of the JBLs and I have modeled it in WinISD..... I know boosting that much may not be a good idea, so I’m still experimenting to see how I can extend the bottom without sacrificing the top end too much... I think for now I’m going to focus on dialing in the Mini and just turn off XT32 until I’m happy with the results..

    Small yet Mighty. The tale of the 12's

    Well I only have to integrate with L/R right now as I'm only stereo (long story)...... I also have a large space because the entire first floor is basically open to each other, plus the loft, etc....... My hope was that the 3x increase in cone surface area would net some significant gains but we will see.... I'm on a slab so some signal shaping will be needed regardless..... I'm going to try and revert back to the blue line..... I'm overly complicating this and the results are only getting worse...
  11. EndersShadow

    Small yet Mighty. The tale of the 12's

    Best part.... they are NOT in play..... so they should help provide some additional smoothness in the response. I did a bad thing and redid everything last night and need to make some more adjustments this morning as the final result wasnt as nice as what I posted above. In the graphs above I cut a lot off the top so I didnt have to boost the bottom end. Last night I did the opposite. I DIDNT cut as much off the top end, hoping to raise the low end post filters and XT32. It didnt turn out as well as I'd hoped, so I'm starting over again in hopes I can almost re-create or BEST what I posted above...

    Small yet Mighty. The tale of the 12's

    So I decided to redo everything again last night. Thankfully since I save all my REW graphs I used the original Average to generate a new filter file and went from there. I was a little bit more generous in the REW flatness target and boost section and I think it paid off. These measurements have no smoothing applied Here is the new filter file. Here is the result of the new average post XT32 v the prior one. The same average v the prior average WITH BOOST. This is all three. As you can see its a fair compromise between them all.

    Small yet Mighty. The tale of the 12's

    Found my UMIK mic and had some time so I started doing some tweaking...... my graph looks good but I need to let things settle a bit before I determine if tonight was a total success. I feel like I'm missing some of what I had earlier this evening. Here is what I did in case someone notices something obviously wrong. I turned off XT32, set the Crossover for my bass in my Denon to 250 and took measurements. I tweaked the distance in the MiniDSP between my subs until it looked the best I could get it. I used REW to calculate filters which I applied to my MiniDSP. Then I went and ran XT32, but each of my subs are on a separate sub channel. Once XT32 was done I took measurements again and they appeared improved. At that point I added my boost and took my last set of measurements for the night. I've attached the REW Filters I used (mainly bringing down the top end) on the initial configuration, as well as the final REW graphs.

    hehehehe.... yeah I know.... and I still got two Sonotubes to wrap up.... Its a combination of both of us being busy and trying to find a time where its not STUPID HOT outside, but not too cold either lol... Yesterday was really hot and humid in the morning and with the shade in the afternoon it got a bit better...... it does help he's got a pool.... Goal is by end of August to have the Sonotubes finished. Then I can EQ everything........ I wish I could go larger like a couple of you guys but thats not a possibility lol.....

    Small yet Mighty. The tale of the 12's

    @Ricci I figured I would at least mention that it may have crossed my mind once or twice to buy one of those 21's since the enclosure opening is 24" tall and 28" wide.... woulda been a really cool look.... but with wanting to match to the other 12's it would have been much harder to make them all play nice....

    Small yet Mighty. The tale of the 12's

    I'm an update on this thread (found here) which mainly covers the Sonotubes. I will post my update from today since its a completion of one of the enclosures. The sonotubes are still a WIP and hope to wrap those up before it gets too cold (but waiting till its not to stupid hot out too).... **************************************************************************************************** Massive update from yesterday. Had a marathon day to complete the Organ Donor build and it is alive and kicking. I got up at 4:30 AM on Sunday morning, got in the car and drove to my buddys in Evansville. I arrived around 7:00 and we got to work quick. First things first we decided to remove MOST of the existing front baffle. We ended up leaving the sides mainly because we were scared of damaging the finish on the visible sides with the cutter. This worked good because it left the mounting screws for the original grill, and also ensured I have MORE than enough space for cone movement before it hits the grill. We decided the best size box was to leaving some space at the top (there are pieces connecting the existing panel together there we didnt want to screw with), and also leave the bottom (original plan was to remove that as well and drop the box to the floor). After those sizing adjustments we ended up with a box with these dimensions. I was shooting for a 6 cubic foot box but in all liklehood am closer to 5.0 (5.3 prior to drivers and bracing). Since its a sealed box and these JBL's aren't known for digging deep, I wont lose much down low, and I plan to EQ them with a shelf filter anyway. The box came along nicely as it wasnt as much a PITA as cutting 150 million baffles for the Sonotubes. Once it was all glued up and the glue set we did a test fit. We discovered our initial plan (the box goes up, rotates in) wouldnt work as the tolerance for the turn was too tight. This was done initially to save the rear horizontal piece that held part of the top grill on, and just looked quite nice. We ending up takign CONSIDERABLE time to remove it as carefully as we could, so it could be reattached later. The box fit like a glove, so tight in fact I will need to install nylon straps at the back to aid with removing the box if I need to work on it as it wont budge unless you pull it out JUST right lol... At this point (it was close to 2:30 PM) I left my buddys house and drove the 2 hours 45 min trip back to mine to continue working on the box. Rather than go with duratex, my buddy had some leftover black speaker box carpet, so in the interest of time I decided to use that instead. It went on fairly easily with spray adhesive and looks great. Plus the front grill isnt easily removed, so I wont be showing that off much if at all. I ended up installing the fabric on the front and back of the enclosure. I also sanded down the bottom of the Hammond PR cabinet and attached fabric there as there is a small portion that could be viewable with the grill on, and it also helps slide the box in. The sides and top currently have no fabric. I HAVE debated installing patches on the side of the Hammond cabinet for similar reasons to why I did it on the bottom of the box. I have extra so we will see. After installing it I did a test fit to ensure it would still fit. Tolerance at the top was tight to begin with so was concerned if I still could get it in. Much easier to man handle a box without 4 drivers weighing it down lol. Some of you may notice I didn't seal all the sections of the box. My OCD lead me to start, and in the interest of time I stopped. I made a few compromises and this is always something I can go back and do later if its even needed (likely not we used a TON of glue when building the box) The rear actually looks better than I thought it would. I was originally unsure if I should carpet or paint it (which would have happened at a later date). I'm glad I went with carpet just to get it done. I think it was around 10:30 pm before I had the box fully carpeted. Wiring the 4 drivers was a lot of "fun". 4 SVC 4 ohm drivers wired to a 4 ohm load. Lots of quick disconnects and fun. I wired and tested them to ensure the were all playing prior to screwing them into the cabinet. Easier to troubleshoot that way. Here is the wiring diagram I used to wire everything. Here is the final product, completed at around 1:00 am on Monday morning (the next day). Its currently missing the front grill which is mounted using screws from behind, so its a PITA to take off, so for now while I dial in EQ and whatnot I'm leaving it detached. It also needs some cleaning up which will be done in the next day or two. Whats left for me to do now is all based on some of the compromises I made yesterday just to get this up and running. I bought a bunch of REALLY nice connectors from David Gage of Deep Sea to use initially, but in order to get it up and running,I just used drywall screws for now. Since I have only a single 3/4" baffle I would have had to install blocking (8 pieces) on the back of the box for each drivers, meaning installing 32 pieces of blocking, then drilling, mounting hardware, etc. I can always do that at a later date. I also didnt have any speaker gasket, but with the carpet and a really tight fit I think the drivers will be OK for now. Also made a compromise on the speaker wiring. I bought really nice 14 gauge Furez speaker wire. The quick disconnects I got weren't super tight so I did a lot of extra crimping to make them work. Also since I needed to combine a few wire together and the disconnects were only rated for a single 14 gauge run, I ended up cutting a 1" section out about 2" above the disconnect and stripping that section, and then pairing the connected wire to it, then wrapped the whole portion with lots of electrical tape to keep it safe. At a later date I may go back in and solder those connections, I just didnt have the material for that on me. I also need to buy some pillows and stuff the box a bit. I'm aware of the data on how a box performs stuff v unstuffed on databass and that I may be giving up a bit of SPL to stuff it, but given that its literally less than 2 feet from my back, I am ok with that. All in all I'm super happy with how this box came out, and feel the few compromises I made were worth it to get this thing up and running. Hopefully today I can get it connected (have to pull out my rack and re-organize) and take some measurements and EQ it. Then I just need to wrap up my two Sonotubes, which we didnt even touch yesterday.

    Ricci's garage sale

    Lol.... it’s not the 21s that would be costly.... it would be the divorce attorney lol.... Although don’t think I wasn’t tempted as the organ sub I’m building has a 24” opening and would be approximately 6cf internal lol..... 1 21” is more impressive than 4 12s lol And same for my behind the sofa build... it’s about 24” tall but I’m limited in depth to 8” total (not just interior).... otherwise id seriously consider it lol.... at least the 4 ohm ones you have (i think)....

    Behringer inuke replacement?

    Correct. Someone else in AVS actually made custom fit covers for his. I think he’d be up to make another set...

    Behringer inuke replacement?

    They do look much better. If I didnt have two Crown XLS2000s myself I’d look hard at these. Would have solved my need for a MiniDSP and saved me some cash...... But then I found another pair of decent amps so I’d still need it since I’m gonna run 4 amps bridged to my 4 subs lol..... Also hello madaeel!
