Subwoofer for Acoustic Zen Adagio?

Well. I have worked on speaker placement for general quality. My work at that time didn't come up with anything that increased the bass a lot. I wouldn't want to do an extreme placement for bass that messed up everything else.

The most bass I ever had was when I bought the Musical Fidelity A5 and was still powering my PSB Stratus Bronzes. Switching to the Unico SE dropped the bass notably, but to proper from almost overwhelming.

Before this stuff, I never would've thought I'd like that much bass. Now I want it along with all the quality the Adagio's have everywhere else. So this is how you get hooked on endless upgrading.

Raul, How do you roll-off the lows from the main speakers ?
My sub does not have "hi-pass" outputs to drive the main amplifier. My pre-amp drives the sub (with its built-in amp) and the main amp directly, so even though the sub handles the lows, the main amp and speakers see the full audio spectrum.

I have found that a very musical sub works well for my tastes with music. Something like the REL Strata or MJ Acoustics Ref100 should work perfectly. If you want something for Home theater to mimic dinasaurs stomping about, then get a more powerful sub with a stiff cone that stands out and forget about music.
