BIC F-12 newbie review :)

concidering $200 investmnet i'm sure happy!

I swapped sub amp [:$] (didn't like texture on the replacement sab) and noticed
that 3 walls (left, right and top) are covered with 1" of polyfill or something
similar but front (where sub driver mounted), rear (where amp mounted ) and
bottom left without any insulation. any reason for that? why they didn't cover
everything?

I've read that polufill will absorb unwanted vaves "It’s a sound absorb­ing,
damp­en­ing fiber that makes bass sound deeper. It pro­vides a cleaner midrange
while get­ting rid of unwanted reverberation".

I have few sheets of the speaker insulation. If I would cover rest of the
walls in my sub box (not gonna cover amp) is it gonna make bass deeper or most
likely effect not gonna be noticeable?

You can try it both ways but I doubt you'll hear a difference. If they were trying to cancell standing waves, you only need to cover 3 sides.

Polyfill make the box seem bigger to the speaker. Too much polyfill and the bass gets muddy. Have to experiment to get it right.

I guess I'm not gonna try to fix what isn't broken.

I'm good for know and not going to mess with my sub.

but I do have a question about MCACC:

first of all my MCACC sets different settings for the speakers every time I run it. difference within +/-1 and +/-2 on sub...

is it normal?

second, if I would run calibration and would set exact the same parameters for all speakers and sub in manual "EQ off" mode does it mean that I would get exact the same sound in "EQ on" and "EQ off"? I have only one preset "EQ" and can choose between "EQ/MCACC on" and "off" only.

I'm not familiar with that room eq software. You might post that question in the Home Theater section. There's a lot of guys familiar with Pioneer there.

ok. thanks.
