Tom,

Thanks for the post. I do not have a SPL meter, and you are right, my wife would balk at the $70 cost of the meter and test disc. She has been supportive of the system so I can't fault her on this.

I have gone through the Denon on screen set up... I have it set to crossover at 80hz (crossover turned off on sub) and have set the M22's to small. As far as the boominess is concerned, I don't know how to adequtely describe it. Its just not quite as razor sharp as I would have assumed it would be from all of the reviews. Maybe I have no conception of what reasonably priced bass sounds like. (I used to work around a VERY serious mix suite with very nice earth shattering bass, and I suppose I took it for granted due to a lack of reference). The HSU is not horrible, don't get me wrong. It's deep that's for sure, its just not uber crisp. Take Norah Jones first album for instance, on "Lonestar" or "One Flight Down" the bass just seems to lag a little and come across as muddy in comparison to the way the rest of the frequencies sound through the M22's.

On Ben Fold's Rocking the Suburbs album, track 6 "The Ascent of Stan," there is a TON of low bass, I mean I didn't know that there was bass that low on this album, I was amazed, but at the same time it seems that I had to crank the sub too far up to be able to enjoy it... by crank I only mean maybe 12 o'clock on the dial.

I think I just need to play around with it some more. My only fear being that the Axiom EP175 would have been a bit quicker and more responsive due to being a front firing sub. Of course it would not have played as low either, so its a Catch-22. Does anyone else having this lag problem with their STF-2? Or is this simply a case of proper placement?
