I just ordered a BIC PL-200 sub which is on the way.
I still cannot believe that PL200 is only $279.
It has been such a pleasant surprise for me in my family room!
When I first saw the PL200 box, one of the corners looked banged up (handle hole on side box). I was a little nervous opening up the PL200. But it was in perfect condition.
One thing about the PL200 is that the owner's manual is 100% garbage.
The crossover that says "OUT" actually means the PL200's internal sub crossover is BYPASSED.
"IN" means the internal crossover is active.
So I would turn the crossover to the "OUT" and let the 3311 do all the crossover, which I set to 80Hz, Small speakers.
Be sure to level match that subwoofer. Recommended is the usual 75dBC for all channel levels. If you like it a little hot, set it to 78dBC or 79dBC or 80dBC like I do.
