  1. 2 more on the way https://imgur.com/gallery/dRGsebY
  2. What are the options for cooling a driver? I would suspect cooling the outer circumference of the magnet wouldn't be much help as the heat is created in the coil winding. What about directing air flow into the screen that covers the core of the magnet?
  3. From my understanding cnc machines often use slightly different software programs so there really isn't a one size fits all cnc file that will work with all machines. Its likely the dxf files on the first post will require some tweaking by the operator anyways. My cnc guy just converted the original pdf files to a format that works with his machine, added 50 bucks to labor price to do the conversion. Prices on the DS and SW are stupid up here in Canada. The best street price I have found for an SW was about 950 Canadian (about 720 US dollars). Thankfully I have a buddy who works for PK Sound here in Calgary, I've been buying mine through them for about 550 US dollars shipped. Only bummer is they have to come right from Italy so it has in the past taken between a month to two months to get here. On that note, I've started building another pair of cabinets so I can keep a pair in my livingroom at home. I'm weighing the pro's and con's of staying with the 21sw152's that I've used in the previous 4 cabs vs saving a bit of money and trying a pair of the DS drivers instead. It will be likely that occasionally Ill run all 6 together so maybe sticking with the same driver is my best move.... but it seems they do provide fairly similar performance. What do you guys think? Should I just stick with the same drivers to match the others? A final consideration is ill be using a lesser quality amp to run the ones Ill keep in my house, a crest prolite 7.5 vs the k10 I use for my others. Maybe the DS will work a bit better on the lesser amp?
  4. Ah, yeah that makes sense... was just an idea. Seems I fucked up putting a pair of my skrams in my livingroom... seems unacceptable to not leave them there. Just messaged my Cnc guy, another pair on the way.
  5. Hey Josh, what would happen if you blocked a port internally where the port starts? I personally don't need or feel the need to play with the tuning on mine but when I was constructing mine I thought to myself it might be easier to add the blockage internally where the vent port starts... It would also look nicer than doing it externally
  6. Ok great! Updated my notes One last question on the spacing. By keeping the subs within 1/4 wave length of each other within their operating freq range, that will ensure no destructive cancellations.... but will it effect the subs ability to couple to each other? Will you loose some output gained by having all of the subs side by side? I think there is a bit of a trap that you can fall into with how many cabinets you really need to fill a space. When I assembled by first system I started with a pair of my old RCF 4pro subs under a pair of the RCF towers. Pretty much right away I knew I was going to need more, so I added another pair of subs. The jump between 2 to 4 subs was a substantial improvement. Maybe a year after I added another pair but that time it didn't feel like such a big jump forward.... I eventually added another pair and ran it like that for pretty much a decade. The interesting thing was occasionally when I deployed only 6 or even 4 subs.... it really didn't feel like I was missing that much power. Obviously there is a point where you need more power to cover larger spaces and larger crowds but you should strongly consider really what your needs are before selling your house to afford more speaker cabinets haha. Not running your gear at full tilt is also a consideration for sure. On the flip side, the other thing I come across, especially in my city is that often crews bring literally too many cabinets into venues that just don't need that much gear. There is a point where I believe too much gear will have a negative effect over the listening experience. Yeah it certainly blurs your vision and re-arranges your guts, but if the low frequency pressure is so high that it literally overloads yours ears ability to discern what the rest of the music sounds like I really don't see the point. I suppose maybe some people simply want a visceral physical experience like that, but I think more people really want to experience the full range experience of the music artist they came to hear. For the venue sizes we use, I can't really think ill be left wanting with what my 4 skrams can put out..... maybe 6 just to get off the gas pedal a bit... but 8 would simply be overkill. I've got that paper bookmarked, there really is some good info in there. I used to get a fairly narrow hot spot out the front of my 8 old subs. Splaying them in a arc really helped even out the coverage out front... such a simple way to improve the directionality of a sub array
  7. Thanks for the formula, I had read an article by Nathan lively that described this but his formula was a bit different, allowed even wider spacing. When you say 3.3 feet apart that should be center to center yeah? Or 3.3 feet between cabinets? And what frequency would you use in the formula? The crossover frequency? I guess you would want them tight enough so that any frequency produced by the subs would fall within 1/4 wavelength of each other? And yeah, better to have more than enough horsepower on tap, I would rather run them conservatively vs full tilt all night. Ill have to keep my eyes on driver prices, perhaps after some more rental revenue ill try and pick up another pair.
  8. Agreed... Chocolate chip trip was the most exciting for me as well, it was literally a trip to experience Very cool sound experience, felt like an amusement park ride. I could maybe justify the cost of building another pair simply to give more flexibility to set up arrangements... but so far the 4 have been giving me the horsepower needed for my needs, Ive yet to feel like I needed to run them up to limiting to get the output I needed. They feel very balanced when carrying them, doable with 2 people but a 4 person carry is most desirable, it feels light and easily to maneuver with 4. The show on Saturday went well, client was impressed and has already indicated he wants to use the rig again. It was a weird room, concrete industrial bay, cement walls with metal ceiling. Only 20 feet wide, about 140 feet long with 50 foot ceilings.... basically a worst case scenario for good sound..... I clustered the subs all upright vents on the bottom slightly off center in the room hoping to somewhat reduce low frequency cancellations down the length of the room. It mostly worked, with the room empty walking front to back bass energy did rise and fall a couple times over the length of the room... but once the room got packed (was a humid sweaty mess) it evened out nicely. I ran the Danley's upright in 40 degree horizontal mode which worked awesome keeping sound off the walls, also tilted them downwards enough to keep sound off the metal roof. Bass music all night, low sub frequencies sounded full and clean, mids and highs were impressive considering the room. I did feel like it lacked some kick definition up the middle however, close to the walls the kick energy felt great, but up the sweet spot in the middle of the room it felt a bit lacking... not sure if this was room related or if the upright vents on the bottom configuration contributed to it. Considering the music styles, It wasn't really an issue, I don't think anybody other than me (worst self critic) would have noticed. Next time ill try double stacked vents in the middle, or possibly coupling all the subs on one wall. Considering the venue is only 20 feet wide, I think all 4 subs stacked with vents against the wall might actually work the best in such a narrow long room... should at least minimize cancellations. As mentioned I never felt the need to run it up to my limiting which was set at 44 volts. I certainly did have heat in the back of mind as the room got terribly hot and humid. They sounded rowdy and clean, never distressed and could not feel any discernible temperature on the cabinets. I did have to move a handful of people away from sitting up against the vents... it seemed people were really enjoying ride the skrams were putting out Def worth a listen regardless if your a fan or not. Simply from a production and sound design level its a treat for your ears.
  9. So far I have only tried deploying my 4 in a center block 2 stacked on top of the other 2 with all mouths facing each other. It worked great, nice wide and even dispersion out front with impressive rejection behind them. I wish I would have measured dB in front vs behind but take my work for it they were much much quieter behind the stack, which is super helpful keeping the energy off the stage. Tomorrow I’ll be deploying them in a warehouse space, I plan to run them 4 side by side mouths on the ground, will update how it goes. I do want to experiment with left right stacks at some point, I have wondered how it would work 2 per side stacked in a tower with the vents coupled together.... meaning the vents would be coming out of the middle of the stack off the ground. I suspect they may not couple well with the ground plane like that... but it would make a convenient way to get my danleys up high without needing scaffolding. Might not be best for bass music but maybe work good for house and techno, who knows. Probably best just to build another pair to do 3 per side stacked on their sides haha.
  10. Yeah man! Josh has given us an incredible gift, deepest bows to a true master in his craft.
  11. Na, they are in our studio with the big Danleys. Had about a dozen friends over last night for a listening party with the new Tool Album. Holy shit! I am continually blown away with these Skram subs. Danny Carey's drums sounded so immense! kick drums right in the soul haha! In all seriousness we collectively agreed that none of us have ever heard kick drums sound this good out of a soundsystem. Made for a super memorable night, fuck going to concerts lol!
  12. I figured why store them in the garage. https://imgur.com/gallery/0sg23w4
  13. Its a bit of an awkward cabinet to fit handles for sure. I skipped the side handles on mine. Instead of the knife edge on the mouth I rounded that edge so the mouth could be a handle. 2 people can carry from the hatch handles and 2 from the mouth, makes for a comfortable 4 person carry, but 2 people can carry from the same placement. I did put casters on mine.
  14. Really appreciating this thread, thanks for everyone's input. It seems every step of the way in this game there are so many new layers of learning that are required.
