Curious on this. I live in snohomish county an hour north of Seattle. This is one of a few on my sub list i'm checking out in the 600-700 range.

Welcome to the board, SB, from a fellow Washingtonian. I'm in the wrong part of Washington, and I don't own a 350, but I hope you find an audition. The new v3 EP350 seems to get plenty of positive comments.

If I did live in Washington, I'd be a little cautious inviting someone with that name into my home to listen to my twin 350's, just kidding.

Most people either think I'm a Dr. or some crazy person based on my name.

Congratulations on the new nickname, Dr. Crazy!

So sirquack how do you like the 350's and what version are they? I'm looking to buy the V3 ones with the 300 watt amp in them probably from the outlet store for 685. What's your take on them? do they do well with movies on the low end? i'm sure they do well with music too. I like the daisychain output on them. better than a Y adapter.

I currently own 2 350v3's and an EP600. The new 350 blows away the previous 350 from a few years ago, totally new design, new amp. Great for music and theater in my opinion. Here is a link to a review from Alan back when they introduced the new design.

Does it really get down to 18hz?

Based on the specs, it can achieve frequencies down into the high teens "in room", however, understand this is not at full output. At some point all subs begin to fall off. It WILL stay within a +/- 3db tollerance from 28-150hz. A lot depends on your room, placement, etc. on what you will achieve, this is true with any sub. Also, understand you can't 'hear' frequencies that low anyway.

Anechoic Resp. +/- 3dB 28 - 150 Hz
Room Resp. + 3dB/- 9dB 18 - 150 Hz

I think the reason they mention -9db is the lowest level where you still hear a contrubution. I am [relatively] flat until about 21db and then output drops sharply.

I do not know if you can feel the bass at -9db from reference.

Fred, not applicable to subsonic frequencies, but it's worth noting that at p.392 of "Sound Reproduction" Dr. Toole discusses the great importance bass extension has shown in blind evaluations of speaker preference. The tests showed a maximum correlation between the listener ratings and the low-frequency cutoff when a -10dB level was considered.

Thanks John. I figured it was something like that. Axiom usually has a reason when they put something in their specs.

I really need to buy this book soon.

Why? John's here! Having him around is like having the movie version of the book!

Well, I need more books in my bookshelf so it works better as a sound diffusor, but maybe john could just stand in my room and recite from the book??

I decided to not go for the EP350 v3. I ended up going for the Epik Sentinel sub and spent more then my budget. Not sure which subs out there the Epik compares with but i'm getting it on either the 7th or the 8th next week. I figured i needed some more power.

Congratulations on the purchase. I hope you'll stick around to give your impressions of the Epik. I've heard the name mentioned, but I don't really know much about them.

Epik is another ID company with great product and service from what I have heard. They are on the same scale as Elemental Designs. Many times you see eD, Epik, SVS, Hsu mentioned as the best bang for the buck subs out there.

Looking at the specs and the flatness of the FR, I would say there isn't much out there right now that is close to the performance for that price, except maybe the MFW-15. The EP350 or EP500 would also be in the same league if they had better low end extension, if the specs for the Sentinel are accurate at ~18hz.

The SVS PB12-nsd is about the same low FR and price but the graphs I have seen are not that flat. I wonder how the dip from the mid 20hz to mid 50hz range will play out, possibly manifest itself as that thump I disliked about the PB12-nsd.

Please let us know your impressions of the Sentinel.

the FR on the sentinel seems pretty flat than dips once you get under 20hz unlike the PB12 nsd. the svs is 350 watts while the sentinel is 600 watts and doesn't use a bash amp. Wonder if the dip is a concern i should worry about or not. never heard an actual true sub before so i doubt i'll hear anything wrong or whatnot.

It all changes when you put them in a room, every room is different, and every placement brings about different results in FR. Multiple subs placed around the room is the best option, if you can afford it.

I will be placing it to the left of the couch which is about three feet from the left wall in the room. the side surround is against the wall on a stand and the sub will be in front of the stand. I talk with Chad from Epik today and he said the Sentinel will go down to 14 or 15hz in room. That's what frequency response he gets inside. Pretty sweet. The FR on Epik's page is an outside freq resp not indoors. I would get two of them but only have room for one. wouldn't mind one on each side of the couch though but the right side is the walkway to the front door.
