I read in this thread that after completing the Audyssey setup I should increase the crossover freqs to 80hz (THX). I'm curious if anyone can comment on this, as Audyssey had me at 40hz, 50hz, and 70hz. After setting these all to 80hz, I can hear the sub working much more, and it seems more "boomy" (although much more bass) than what I heard at the Audyssey's settings. Is there a specific reason in setting all the speakers to crossover at 80hz?
I know that the PSW125 is not the most popular sub, but it seems capable and I got a good deal on a refurb. My dilema now is that I have room (closer to the couch) for another sub, and I am debating on picking up another PSW125 to match as I would like a bit more bass feel when in my listening position. I could also mismatch and go with a DSW PRO 440wi or something similar if it would be worth it... thoughts?
See my post above, ref 80hz. It isn't Audyssey setting the crossover, it is the 809 based on the info Audyssey gave it. Subtle difference.
Rationale:- much better explanation in Audyssey web site, FAQ's, and this forum Audyssey Sticky guidelines.
Short version (no order)
(i) frequencies less than 80hz are not directional
(ii) difficult low frequencies better handled in a device designed to ONLY do that (Sub woofer)
(iii) active subs relieve the 809 power supply
(iv) the Audyssey MultEQ filter resolution is x8 more powerful at correcting for room issues than the other channels - so better flatter response.
I have probably missed a few, but you should read it from the experts for more info.
For the 809, I would recommend using 2 similar subs. To be placed as indicated in attached (from HK White Paper).
