Right. That's what I figured. Thanks.

Myrison,

The graphs are telling me that the EP600 is performing far better than the earthquake. The blue/green line is VERRRY pretty and quite flat (looks be be about +/- 4 db to me from 20-280Hz). This is with no additional room equalization as well. Looking at that 20db difference at 20Hz between the two subs is amazing to me.

The "punch" may just be that your ears are used to a non-flat curve, and your listening preference is now skewed to a specific peak frequency.

In the end, you have to keep what you are happy with. If a cheaper sub that doesn't play "true" gives you more listening pleasure, then you may just have to downgrade.

That's some very good advice.

Thanks guys, agreed. The FR looks decent to me too. If I could get the defective pieces fixed I could at least focus on the sound... (the FR curves don't show the constant rattle) but lump those problems onto the fact that it's not quite what my ears were hoping for and I think it's likely that I'm going to have to send this back. If that happens, I will definitely miss the low end it provides for HT. Why does this have to be so hard?!

Btw - I made a typo - I meant 20-80Hz, not 20-280Hz.

Mojo, you heard the new EP350's right? Did you think they had the punch that myrison is looking for? He could get 2 EP350s for the EP600 and still have money left over.

I don't see why eqing it and bumping up around 60 Hz or so (making the curve unflat) wouldn't give you the infamous "punch" which I'm now starting to suspect is non-linearity.

Mojo, out of curiosity, have you ever run a FR curve on the Sony sub you have that gives you the sound you like? It'd be interesting to see if it is the non-linear curve everyone thinks we're talking about.

Yes Jason, your EP600 curve actually looks pretty good from about 20-85Hz. The very sharp drop centered around 90Hz may be due to the measurements being taken near the middle of the 12' room dimension, with a resulting null theoretically around 93Hz.

The point that's been brought up previously about a possible unusually low EP600 input impedance still apparently hasn't been explained, and again, it would be nice to know the spec.

I admittedly didn't spend a lot of time on the specs of the 350s before purchasing the 600. It's amazing when you compare the specs how similar they are, though there isn't a FR curve posted for the 350... For my modest-sized room, I'm not sure I'd miss the extra volume the 600 offers as I don't come anywhere close to topping it out now.

I know sirquack picked up a pair as well and also has the 600. Randy, if you read this I'd be curious on your opinions or anyone else who has heard them both.

I just finished watching Beowulf. This was an absolutely entertaining movie. The 600 performed wonderfully with the exception of some really loud LFE at the very beginning where I heard the strange driver noise that some of us have been complaining about.

The 350v3 definitely packs more musical punch. I absolutely loved that sub for both music and movies. It's a fantastic compromise between the "boring" punch that I heard from SVS and the lack of punch from the 600.

We have never seen the frequency response curve for the 350v3 but most likely it is tuned like a traditional sub. By that I mean that it extends well beyond 100Hz and does not have a flat response. Axiom has never published the curve either because it was never able to put it up on the pole before winter came or it simply doesn't live up to Axiom's linearity standards. It appears to me that the vast majority of consumers out there go with SVS or Hsu because they like the non-linearity. So it appears that when it comes to subs, humping and thumping is a good thing. Axiom would likely have a larger sub following if it gave people the choice to go linear or non-linear via a switch.

Unfortunately I've never plotted my Sony. Definitely it's a non-linearity that is causing the punch and it's a darned pleasing one . The degree of non-linearity appears to be a bit of an art. The SVS had too much and it got boring. The 600 has none and that's boring too. The 350v3 gets it just right in my opinion.
