Ive just bought some bipole surrounds (Eltax B.6) and would like to know the best place to position them. I have read conflicting reports regarding this - some people say the back wall, some the side. Ideally I'd like to put them on the back wall, about 1/2 meter from the side walls, and two metres from the floor. Also, I now have a pair of Kef Q15s going spare....would there be any point replacing my Q95C centre speaker with one of them? I know the 95C is a dedicated centre speaker, but would the Q15 be a better match tonally for my front Q35s? Thanks.
