I guess I'll post my impressions of the subs we listened to. Everything was crossed over at 100hz and everything was ran about as loud as it could handle. I was probably the least technical guy there so I'll just post my impressions. This is the order of the subs we listened to as well.
After the first couple of subs we opened up the window because it was getting warm, so the room couldn't really be pressurized so I may of not gotten as much out of the low notes as I should have. You can kind of read my opinion on that on my Worx review.
Bic H100- This is my sub and at the $250 point I enjoy it. It was the cheapest out of all the subs, so it can't do the stuff that the other subs can, but it doesn't try to and distort the sound either. I'll let other people comment more about it since I've probably got some bias.
Outlaw LFM-1C - I thought this was definately a more musical sub than the Bic. It had a pretty good sound to it on the music, but when we switched to movies I prefered the Bic.
ED A7S-450 - Big step up in output from the first 2 subs. Did highs pretty well. Kind of overpowered the mains so it may of sounded a little muddy. (We ran the first few subs about 10 or more hot so thats the reason). I thought it did pretty good in the output department.
(both the A7S & Shiva are mjgs)
Shiva- For the price point it was probably my favorite sub of the day. It had less output than the A7S-450, but the SQ seemed a little better. It does seem to go lower than the 450.
TC Epics- They had a large amount of output to them, but couldn't go very low.
ED 1902 - Pretty good output to it. Tuned to 15hz so it was the first sub to actually be able to rattle the doors a bit. For Brandon's application directly behind his seat it probably would shake things up a bit. A couple of times I thought it started smoking, Brandon said there was some sawdust still in it and when we hit a couple of low notes it made the saw dust fly out. It was pretty cool to watch.
LMS 5400- This is the sub that I basically came to listen to. I was expecting a lot from it and it didn't dissapoint. I could feel this sub the most out of everything we listened to. My impression was...this is what a sub should sound like. I wish I could afford about 4-5 of them in my home
XXX- Similar in sound to the LMS. Does need a bigger enclosure though per Ricci, so that has to be accounted for in WAF as the LMS is in a rather small encloser comparatively. It could go down lower than the LMS, but I couldn't feel it as much in my chest. Very nice sub though.
Worx- Pretty cool sub. It could only go to around 25hz or so. To be honest before the meet I thought I needed a sub that could go down to 10hz or something crazy in order to get everything. I seemed to enjoy things the most in the 20 to high 30 hz range the most though because thats what I could feel. It made me realize I could be very happy with a sub that could only go down to 20hz or around there. Lot of output, not the prettiest sub in the world, but I wish I could have a few in my home.
Danley- I didn't write down the model #s so I may get them confused so forgive me if I do. The first one was the smallest I believe the CS30. I've never heard a horn sub before and it definately has a different sound. The CS30 had some crazy output in the mids and rocked, but I felt the highs weren't at the same level as the mids that it did.
THSPUD- It is designed for you to sit your cough on it and go from there and since it was stood up on its side we were listening to it at something other than its intended purpose so you have to take that into account. Sounded good, but I couldn't feel anything from it...until I moved up within 5 feet of the sub. Once I did that I could feel my pants vibrating. I put my head down by the port and I could feel the sound pushing on my head, it was a cool sensation, but I couldn't handle it for too long.
Unfortunately I had to leave before the Danley 50 was done so I can't comment on it. It was a 4 hour drive and I didn't get home until a little after midnight.
Feel free to ask any questions about what I wrote.
