Anyone with a high-end home theater sans sub?


Is anyone else out there enjoying a high-end home theater without the contributions of a subwoofer, e.g. 7.0?

I always planned on getting one (partly because folks selling speakers say I need one), but enjoy what I've got enough to question spending another $2-$5K on a sub(s) for the deep bass extension.

(As a reference, I have Aerial 8b's, 2 pair of SR-3's, CC3b, Meridian 568v1 processor, and Theta Dreadnaught amp.)

i have a 4.0 system using gershman acoustics avant garde rx-20 in the front and mirage frx-r for rears. however, i wouldn't totally classify it as a high-end home theater. it's a high-end two channel system with a mid-fi home theater around it (denon avr-3805, dvd-5900, mirage frx-r, sony vpl-hs3 projector). the gershman's go deep enough that i don't really want for a sub.
If you were watching sitcoms and sports it would be acceptable, but for movies a sub is a must. In fact, ROTS is out tomorrow and I can't wait to watch it and hear it - with the sub.
I have a Meridian Reference 800v4 and 861 v4 with 5.0 full range DSP 5200 and there is clearly no need for a sub. It slams and crunches with bass.
