Help with Rear Surround speaker selection

How much space behind the rear row to the speaker mounting point? That will help with your decision.

I have heard great things about the Primus speakers. Especially when used in conjunction with the Beta series.

I am a little more interested in the OWS-1 speakers personally. I need a pair for my rear surrounds to match my Beta's due to having a row right up against the rear wall.

I would scratch the Polks as they are not a good match for the Beta's.

Let us know what you get. Of course if you get the Primus, I would be interested in getting those OWS-1

after much debate, and being in the same price bracket as you, but with 4 channels to fill- i got the BIC 62si for all 4 of my rear channels. They were the right price/quality for me, sound great when i got them, after 30hrs they really opened up and sound better than my fronts! i added polyfill aswell (two $5 pillows from ocean state) bout 110 a pair.

The sony SS-b3000 are highly regarded aswell. 110 a pair, but larger.

Real tight budget. The B652's are well known and reviewed. cheapest bang for you buck 50/pair

Dont feel like you have to match your rears to your front. Its only really important for your front stage (L,C,R) to match. Remember its more ambient sound. your not even supposed to point rear channels at the listener, only the fronts. Again ambiance.
