surround back speaker - help

[alex aleluia]

good afternoon, i don´t know if i´m in the correct forum to ask this but here it goes:
my amplifier is the YAMAHA RX-V757, and i have the following speaker setup:
front speakers - B&W DM601 S3
center speaker - B&W LCR60 S3
surround speakers - B&W DM302
subwoofer - YAMAHA YST-SW225
now...my greatest doubt: what is your opinion for the surround back speakers i should get ? and should i choose one or two speakers ?
thanks in advanced :)

You could move your B&W DM302's to the rear and buy a pair of DS6 S3 for the side surrounds. This would match your front and center speakers.

I usually recommend polar surrounds for the sides. But without knowing your room and setup, they might not be easy to work with.

hummm that´s a very interesting proposal, by the way: my listening room is in the atic, about 2 meters high, all the ground as carpet and walls and ceiling completely covered in wood, two meters space all around the speakers position...anyone as other proposals ? thanks !

get another better B&W "set"(pair) for the front and put the fronts to the rear.
or get a similar set as in use now in the front for the rear.
Sometimes good used speakers are about.
Get a lower good used B&W model for the rear.
