Well, this is pretty late but since the gtg things have been real hectic. And the hurricane didn't make things any less so. Hopefully everyone else who was in the path of Sandy is doing all right.
This was my first gtg and it was a whole lotta fun. Can't wait to do something like this again. Met a bunch of great guys (even that hillbilly - you know who you are - hey, Mark Cuban says hi), listened to some loud music and movies and had some tasty beverages (not to mention that awesome pulled pork). And props to Andrew for hosting the event, allowing us into his home and being the gracious host.
Since so many have already posted their findings on the event, this may not offer much of anything ground breaking. But it is another perspective on what was heard nonetheless. (And my apologies if I offend anyone with my opinion on a sub they brought.)
First of all, it was not exactly home field advantage for the single subs. The listening area was a pretty good size and as stated in the gtg thread by Andrew, the room is bass hungry. That being said, most of the single 15 inch subs auditioned would be more than adequate if using two of each or in rooms smaller.
I was very interested to hear this one as it was a contender for my dollar when I was last purchasing an ID sub. However, it was a little disappointing. The reason being the statement in the previous paragraph (room size). Sure, it didn't have that room filling, shake the walls hit but in hindsight, that is not surprising. The other being it was not a tight as I thought it would be. Don't get me wrong, it was not muddy or boomy. It simply wasn't as tight in some of the music as I was expecting it to be. This is not an across the board statement as, for some of the clips, I do have in my notes "clean" and "articulate."
Another sub I was really looking forward to hearing. My thoughts (for music) were "impressive, clean" has authority and is articulate. For movies it did surprising well with sub 20hz content. Did a nice job with the "Pulse" clip and even though for this sub I was seated a bit back in the room felt it in my chest during the "Hulk" clip. Suspect two of these in this room would be quite impressive. Add in the price factor and PSA has a real winner here.
I'll try not to turn this into another apology to Rythmik post (but I make no promises). My opinion is certainly not biased at all
but I felt this was the cleanest sub with music and did the best blending in with the mains.
With movies there are two issues - user error regarding setup as well as lack of cranking the volume up. If you look at the graphs in post 8 and see that big dip at 70hz, that is not typical of this sub. In fact, that was a result of trying to use the subs built in PEQ without sufficient time to do so and lack of experience using it. That dip certainly had an impact (or lack thereof) during playback. However, even with all that, until we got to the bigger boys on the block (which were also duals or more - looking at you Mark Seaton) this one shook the projector the most - again, until we got to the bigger subs at the event. Come on, it took dual Caps to dislodge the PJ for cryin out load.
But this is another sub that would do quite well to fill that room and shake the paint off the walls when a second one is added.
The "issues" encountered during this demo are well documented earlier (that 23 hz filter, low volume playback). However, this one left me with a sense of unrealized potential. I would really like to hear this one again but next time "unchained."
Very much impressed with the ported Rythmik. Only going back to back can you tell the difference with the sealed Rythmik (with music the sealed is a bit tighter, cleaner). However, when unleashed and cranked up, it was very impressive with the movie clips. (Dstew was not afraid to turn it up and this sub did not disappoint - go back and look at the video clip to see the tp flapping in the breeze and of us giggling like loons.) It is very tough not to keep comparing to the sealed Rythmik instead of to the rest of the subs heard that day. Suffice to say, anyone who values their music listening but who also wants impact for movies will be happy with this sub. For me, my preference is for the sealed sub and the more accurate reproduction for music. So, as always, it comes down to personal preferences.
Dual DIY LMS 5400 Ultra
At this point I think everyone agrees that Popalock is nutz (but in a good way). Most people think they're hard core because they turn it to 11. Well, Popalock turns it to 12 and then rips the knob off. And then wants more subs, amps, speakers and volume.
I'm finding it hard to write constructive thoughts on this setup due to the (well documented) clipping that was occurring. Don't get me wrong, this is a very impressive build. But I want to hear it again when we have proper amplification to do justice to the driver and build (still can't get over how quickly one of these was rebuilt and what a great job was done on it). Even with the clipping, this was still impressive. It was pretty accurate and went plenty low. This setup is just screaming (sometimes literally) for a healthy set of amplification ballz to realize its potential.
JTR Passive Captivators and (3) Seaton Submersives - 2X Submersive HP and 1x Submersive F2
I'm lumping these two (ok 8) together. There is ample discussion of these subs all over the interwebz and here at AVS. These subs are on a whole 'nother level compared to all the other subs here (except the LMS's bridge the gap - and may fit in this "class" with the right amp). Let's face it, we're talking about single 15" drivers versus two 18" or six 15" inch rigs. Hardly comparable. Not to mention that Mark cheated. Look at that setup - EIGHT drivers. No wonder the JTR's cracked the foundation and the Seaton's moved it two inches to the left.
My thoughts are probably going to buck the trend. I felt the JTR was cleaner on the music section than the Seaton setup. I was in the back of the room during these subs demo's and the discussion was whether or not the Subm's should have been that close to the wall (given the driver being so close) and if this was having an impact of making it sound less articulate ("muddy" would be a bit harsh here but you get the idea). So, it may sound backwards but comparing these two, it seemed to me (and a couple others) that the ported JTR was a cleaner, more articulate, accurate sub. Are we splitting hairs here? Probably. But that's what we do isn't it?
When it came to the movie clips, WOW! First off, the JTR dislodged the projector, what, twice. And for good measure knocked down a bass trap. The Subm/F2 was no slouch either. It took a day for my internal organs to reconstitute themselves back from being liquified.
Let's face it, anyone would be more than happy with subs from either company. They are truly impressive and anyone with any interest in bass must listen to them.
