Randy I didn't know the two subs utilized different drivers as well, I was just curious if my old 350 could benefit from the larger amp. I did connect the 350 on the opposite side of the room of the 600 and I just don't believe it has enough to keep up, I may leave it there for a little just to see but so far I don't know if there is going to be any gain by adding it.
It does give me a very good refresher of just how well of a sub that big 600 really is though.

Hi all,
Yes, the EP350v3 uses the same driver and the same enclosure as the EP500. However, the amplifier is different and lacks the DSP control that the EP500 has.
The new EP350v3 amplifier also uses a touch of analog EQ to goose the low-frequency output a bit. I don't think the new 350 amplifier would fit into the old 350 enclosure.
Regards,

Hitting 21hz in room, is most likely just due to room gain effect.

Well I have not read thru all of this thread I can answer RickF's question as to the benefit of adding the new v3 amp to the EP350.
I recently had my amp replaced with the new 300w amp.( The sub input plug broke off when I was unhooking the sub-cable) Axiom looked after it on warranty and sent me a replacement amp and I was happy to see that it was the new v3.
It has made my subwoofer really wake up. It seems to have much deeper bass than it ever did before. I actually wonder if there was something wrong with the old one all along, even though I know it did work.
It does fit

Here is a typical rolloff for a ported 12" driver:  The -3db point is 24Hz. If I go down 7Hz from there (the equivelant of 21Hz in my room) the sub is down another 11db. Typically room gain is 4-6db per octave meaning that at 12Hz you would see 4-6db of gain. In contrast, 11db gain by 21Hz is a huge amount of gain. I think this is more than can be accounted for by room gain.

What is the subs extension like when in other positions? This would tell you if it is room gain or not.

Skreefer, but the it does fit comment I take it this is a new amp in the old v2 sub?
If so, that deeper sound is probably due to the dsp boost.
