    Adire Audio is back?

    Based on what little I’ve heard, my impression, which could be wrong, but my impression was that the new people in charge aren’t necessarily engineers. So it is possible it is a brand resurrection based on their previous good name. I agree that it would be nice for new drivers to rebuild the reputation but I’m not sure if that will be the case but I hope I’m wrong.

    MicroWrecker build thread

    Yep. https://spacemath.gsfc.nasa.gov/weekly/6Page53.pdf I primarily use metric for my designs, which was primarily driven by my purchasing a Festool track saw over a decade ago. I have no clue why the US doesn’t join the rest of the smart world in switching to the metric system but there’s no discussion of that, I guess the US has too many other problems to try to solve.

    MicroWrecker build thread

    You guys are lucky that construction quality is that good. Even following code, construction is often not that great depending on where you live in the US, so if you’re in a normal apartment in the US, I doubt you could have even a Sb16 without getting into trouble even on low volume. Now bigger/taller buildings might have concrete floor construction and likely wouldn’t bother neighbors as much but that’s definitely not the norm where I’m at. Looking good and sounds like a good plan.

    MicroWrecker build thread

    Second floor apartment? Really? When I have people ask about my subs and find out they’re in an apartment or connected condo, I tell them my subs come with eviction notices. Good luck with those and the fight to keep them. When I first turned on 3 sealed 18s for my wife, I said if that was too much vibration, we could put rubber feet under the couch. She looked at me and said, “you most certainly will not, that was awesome.” And I’m sure people ask why do you need a car as fast as a Bugatti. If you have to ask, you just don’t understand. Luckily, our subs are a heck of a lot less expensive for their capabilities than someone buying an exotic car.

    It’s not quite a sealed 24 but it might wreck something. Lol! I kid. Looking great so far.

    Mr. Ricci, can you design me a ported box for the SI HS-24 with no more than 8 cu.ft. of enclosure volume? And can you tune the port to 12Hz please? You’re the bestest! Thanks Josh. Happy Holidays guys! Thanks for hosting such a magnificent and informative site!

    Paradigm Persona Sub

    And here is the picture of Brandon's previous setup that we knew and loved. The speakers on the left and right are Danley SH50s and the center is a Danley SH96 I believe. The 4 DO boxes have the old popular Stereo Integrity HT-18 entry driver that so many used and still do. Really was a nice setup. His current setup has some nicer JBL 4637 speakers and one of Josh's SKHORN subs.

    Paradigm Persona Sub

    Haha. Very serious. I don't like dual-opposed subs for that very reason as too many times I've seen/heard them with one driver facing out into the room and the other firing into the wall. And since both drivers, now with completely different phase and frequency differences, are driven by the same amplifier/signal, you have to DSP them together. You'll never get an optimal setting that way and what I usually heard, namely smeared sound bears that out. However, if dual-opposed subs can be placed along a wall and one driver isn't firing into some object, they can work well. However, I just don't feel that their advantages outweigh their disadvantages in placement with the primary advantage being an inert cabinet since the drivers cancel out vibrations. A well-built sub doesn't need dual-opposed drivers to still have a strong, vibration-free cabinet. Now I've heard one setup with dual-opposed subs that was about the best setup I've heard and you've heard it too, which is Brandon's dual-opposed setup. His quad boxes were placed optimally in the front corners at a 45 degree angle to the side wall and front wall. Add in the fact that he had one pair on the floor and the other pair stacked near the ceiling on top of his speakers, he had one of the best front-sub setups available and it sounded like it. I looked for a picture of the setup he had then with the Danley's but couldn't find it. I'll see if I can get him to send me a picture. By the way, this post is sort of ironic as I'm thinking of offering a dual-opposed subwoofer that I was previously opposed to, primarily because a customer wants it to be able to place it correctly parallel to a wall.

    Paradigm Persona Sub

    I have 2 concerns with that sub. 1. Where are you going to place it so that you don’t have potential phase issues with some sound coming directly off of the drivers while other sound waves will bounce off of the wall or furniture? 2. They mention 12 Hz output in-room, which I can believe but I’m concerned it might not be very loud and impactful. 3. And just thought of a third when I found the price. I think you could do much better with some of the Internet-direct 18” or similar subwoofers. Funk, JTR, PSA, Seaton, or Deep Sea Sound would probably perform better at a much better value. FYI, I started Deep Sea Sound.

    Now you hold on. Don’t mess with my fake sounds in space because I love said rumbles. And can you imagine how boring a space movie would be without sounds in space. Duh!

    Othorn - HT capable?

    Haha. Yes my definition of a smaller subwoofer is completely asinine. I think my skewed definition took hold when I first heard the SI HS24. Lol! Now I often have customers contacting me wanting a single 24 and I’ll often try to steer them toward a pair of “smaller” 18” subs for more even bass response. But really, a pair of 18” sealed are really impressive with output easily in the 120s with the ability to play down to 10Hz flat in room. Of course the room and more importantly, the floor have a huge impact on how impressive the sub system. Large sealed subs on a wood floor are oh so impressive but not nearly as impressive on a concrete slab.

    Othorn - HT capable?

    I've stayed out of this conversation since I'm not a ported or horned guy and haven't heard a horn in an optimal setup yet. But for me, multiple smaller subs is preferred and recommended to get more even bass response in the room. Regarding how bass is perceived, if we compare an 8" midbass driver with a 12" midbass driver at the same volume, the impact of the 12" is noticeable over the 8". I'm not sure what the physics are but I liken it to a towel being snapped, maybe the 12" snaps quicker because it doesn't have to move as far as the 8" driver to reach the same volume. However, I haven't noticed a difference in impact between my 18" and 24" sealed subs so maybe the impact doesn't translate at (much) lower frequencies or I'm not doing it right.

    Horn length extension on Othorns?

    Geez, just wall it off and get a rotary sub already. Now that is some bass headroom!

    Woofer for 40-250Hz?

    Many people have used the JBL 2242H and 2226H drivers for midbass both sealed and ported. They are solid drivers, easily available on eBay, but I don’t know there is anything that sets them apart from the BMS or AE, especially if they are more expensive or harder to get. And I’ve also used the AE for midbass drivers and they are really nice too.

    Woofer for 40-250Hz?

    I have similar JTR 212 HT-LP and use the JBL 2226H drivers. I actually bought a bunch of JBL 2226H drivers for a project I never got around to and need to put them on eBay. Really impressive midbass in a pretty small cabinet though that AE cabinet looks pretty modestly sized for this board.

    You act like you know so much about Obsidian. Hint - Electrodynamic was also the owner of Obsidian but decided to combine the car and home audio offerings under the Stereo Integrity brand.

    B2 Audio XM18 vs Dayton Ultimax UM-1822

    I was thinking of my follow up response. I kept thinking, sure a couple 18s would be phenomenal and may fit into his budget now. If you were to buy 4 HST-18s, you’d have one of the best subwoofer systems on the continent. Or a pair of HS-24s would do the same though the quad 18s in the corners would provide more even bass in most rooms. Realize that we’re talking about bass systems in the top 1% in the entire world. That is going to cost some money but then again, is a value compared to what most uninformed consumers pay for their “high-end” audio equipment. Either way, this system should last you 10 years and likely many more than that so I’m of the opinion to save your money and get what you want. Or even better, start with a pair of 18s and add a pair of 18s later and you have almost the equivalent of a pair of 24s and more even bass. Or buy a pair of 18s now and add a pair of HS-24s later where the 24s would be up front and the 18s in back. And if you want the real deep bass and smaller cabinets, that would be sealed and I oh so love the sound and tactile feedback of my sealed 18s and 24s. Then again, if you’re not interested in single digits or are on concrete, then a ported 18 may be the way to go. You’ve definitely have some options and won’t go wrong listening to the experts on this forum.

    B2 Audio XM18 vs Dayton Ultimax UM-1822

    Thanks. Not familiar with the IB-24 but I’ve heard both HS-24 models, BHS-24 (130lb beast!), both HST-18s, HST-15, HT-18, and BM MK IV(12” car). All of them were high quality and high performing. Even more important to both of us, me for business and you for distance, the subs have been very reliable though I would recommend having Nick go through an extended burn-in period in your case. I have no reason to doubt the IB-24 as it shares the same pedigree with which I am so enamored.

    I’m a biased fan of the SI HS-24 driver but I also have more experience with it than just about anyone as I’ve measured it in many different rooms of different shapes, sizes, and construction. My 24s have measured flat to 7 Hz in every room except one, which was flat to 6 Hz. And I haven’t had a customer with my 24s get near their full output capability, which is easily in the 120s depending on the frequency. So it really depends on what you’re looking for. If you want effortless output above 15Hz then I’d recommend ported like LukeAmdMan did. If you’re willing to give up some output capability (efficiency) to gain full extension, then I’d highly recommend the 24 in a sealed enclosure between 300 and 400 L. And it really is easy to DSP the sub to be flat as the mk II driver has a mild inductance hump. Take a look at my website (Deep Sea Sound) to see how flat I was able to get the HS-24 using 3 minor DSP settings. Regarding sound quality, the HS-24 mk II is up there with any on the market. I used to own the TC LMS-5400, which was lauded as one of the cleanest, lowest distortion drivers, so much so that some people didn’t like it as it was “too clean”. Most people aren’t familiar with low distortion bass and the LMS-5400 was definitely clean. I put my LMS subs up against the HS-24 mk I on multiple occasions and the 24 had more output than a pair of LMS-5400s and didn’t give up anything in regards to sound quality. The HS-24 mk II driver is even better than the original in all regards except power handling, which is the same. I don’t think you can go wrong with the HS-24 sealed but it really depends on what you want. I don’t know about ported as I’m not interested in working with refrigerator size cabinets and as I said previously, my customers haven’t needed any more output than a pair of 24s provide.
