A lot of the guys have already commented on things and I agree with most of what has been said so far. This wasn't a contest to determine a winner and it wasn't a testing and measurement session. I would've loved to do that kind of thing, but with the amount of equipment and people there, plus the limited time frame, it just wasn't possible, which I think everyone quickly figured out. I was supposed to get there around 10:30 or 11 and help get things set-up, but I didn't show up until after 1pm. We were already running late and due to a navigation error with the GPS on an Iphone, we ended up a few counties over at another Shady lane about an hour and 20 minutes from the house! Ooops.
I believe that there were around 20 people there at one point and over 10 subwoofers.
Basically, we just dropped the subs in an available spot, roughly level matched all of the subs and let them go. We switched through them back and forth a lot playing the same tracks. No EQing, LTing, or fine tuning of them. We just didn't have time and the prospect of tweaking everything. We didn't even get a chance to mess with the SDX15 I brought. Moving all of those heavy bastards in and out of the way to use the same in room spot was daunting to say the least as well. We also had to switch the pre-amp twice during the day. Later on we basically just used the CE4000 bridged for all of the DIY's and switched the cable (speakon FTW). Maybe if there were less people, more time and way fewer subs like maybe 4 to 6. That said what we did do was: have a meet and great, a few beers, some food and a good time listening to some subwoofers. Nothing wrong with that at all.
I think that even with the different room placements and general flurry of activity, there was enough there for everyone to get a feel for what each subwoofer had going on.
I also think that some of the guys who aren't that familiar with the DIY side of things got a good glimpse of the madness. We had raw drivers, enclosures and amps everywhere, John put together the AV15 and PR's sub in the workshop, I put together the LMS, Patrick was drilling out holes and wiring up speakons, we were mounting drivers, smashing fingers, cursing like sailors, etc, etc. I believe that Chris video'd most of the process of preparing and mounting the XXX. Good times.
My impressions on some of the subs is as follows...F112
I liked it. I really don't have much to add to the thousands of descriptions already out there. It was by far the tiniest and best looking sub and it sounded good from the limited time that I heard it. The build quality is excellent. It obviously was not the output champion, but it was impressive for it's size. I wish I could've heard it more.Rhythmik's
I didn't get to spend much time listening to these unfortunately as the sealed one was only there part of the day and I was late. I thought the sealed sounded better from what little bit I did hear, which seems to be the consensus. Could've been room placement or the set-up though. They both did appear to have a nice upper end of their range through the x-over region. The sealed Rhythmik was finished very nicely. Hopefully someone has a pic. It was second only to the JL on fit n finish.ED190v2
I didn't listen to this one much either. What I did hear of it left me with the impression that it was a good budget driver, it rolled off the upper bass around x-over a bit, it would get loud with music, but will not shake the room with lows like the other 18's would. Gives up the ghost earlier. It's not on the level of a Mal-X and definitly not an LMS. But the entry price is much lower as well.LMS
It's mine, so I know what it does and I'll let other people comment. I thought that it was right there with the best SQ of the bunch.TC2K
Maybe it was the placement but this did seem to have a perceptible amount of softness in the x-over region compared to some of the others. It was clean though. Both Patrick and myself prefer the TC2K over the 3K. Not a bad driver.TC3K
This driver had the most obvious difference in the punchy upper bass 70-100hz. It was noticeably softer than the AV15 PR set-up, or the MAL-X which was right below it. It also seemed to be pretty innefficient. It was still clean sounding but obviously darker toned and less snappy than the TC2K which was stacked on top of it. I would say that it had the most low grunt out of the 2 though and probably the most out of the 15" drivers.AV15X PR'd
I thought this thing sounded great. From what I heard I'd put it right up there near the top of the heap SQ wise. It was punchy and clean sounding to me. John had a track with a clean un processed sounding bass guitar recording and it had a very fast run of low notes on it that really accentuated the note tracking ability of this sub. The TC3K and TC2K sounded less crisp and defined on that track. Of note here is the fact that John's sub was set-up on the wall by the entrance of the room , which had a hallway, a couple of doors and along with the XXX was the only sub to be set-up there. It also seemed to be pretty efficient and would jam when called upon. At one point we were in the garage talking and someone was cranking on it a bit and you could feel the concrete floor vibrating. Everyone thought it was the LMS. It did have the biggest enclosure of the group. I'd guess it at 26" all around. It was one of only 2 resonant alignments in attendance.Mal-X
I thought it sounded good and aquited itself well. It seemed reasonably efficient and had a nice sound to it through the x-over area. Compared to the TC3K and TC2K stacked immediately on top of it, it sounded clearly superior to me. Much clearer than the ED190v2 as well I thought. I really wanted to spend a significant amount of time comparing it to the LMS and XXX, but we just ran out of time. Mainly it just seems to give up a bit of ruggedness and some useable output to those two. It is also significantly cheaper though. Patrick can probably expand here. We had a good conversation on these. I know that he knows what the Mal-X can do, as do i for my drivers and I trust his opinion and thoughts on it.XXX
We didn't get this ready to go until late in the day and many people had already cleared out. It performed as I expected. Let me add that I was worried how it would sound in a box that small and those worries have been laid to rest for me. I'll be running mine in a 24" cube in the future. At the point that we got this running it was later in the day and the volume level had steadily crept up all day, as people wanted to see what things would do. It was subjected to a harder beating than any of the other drivers and it didn't dissappoint. We did clip the Crown REALLY hard into it with a 7hz note that Patrick's son had on some crazy bass track. I think that we got the full 108mm p2p plus some suspension stretch on that one. No damage. I had to actually say "hey why don't we switch over to some more SQ oriented tracks and lower the volume so we can listen to the x-over area" at one point. I think it surprised a few people when we did.
