Right now my main issue with my HT is that my rear soundfield is too narrow. Unfortunately, I am constrained in that I have to wall mount my rears horizontally and near the ceiling because of insurmountable WAF issues. Right now I have a pair of Paradigm Titans up there resting on their sides. This produces a very narrow sweet spot. The speakers are pretty accurate, but I crave more envelopment. It occured to me that replacing them with multipolar speakers of roughly the same size could help out. I have Paradigm Studio 60's and the Studio-cc center right now in front, but I find timbre matching with surrounds unnecessary (the Titans aren't Timre matched to the mains anyway). The Axiom Quadpolar surrounds caught my eye in terms of price, size and horizontal orientation. The Paradigm dipoles are vertically oriented and won't work here. I was considering either the Qs4's or the Qs8's. I am seeking opinions as the following: 1. Sound quality. Wide diffusion? 2. How easy are they to wall mount? Do you need to purchase brackets? 3. How do they look with the cherry finish? If the finish is cheap or fake looking, I'd just assume go for the regular black finish. Thanks in advance.
