Hi there wise ones, I'm looking to buy a centre speaker. At the moment, I do have a fairly budget system, with Eltax liberty 5 front speakers, liberty something (i forget what) rear speakers, running off a Marantz SR-4300 amp. So I'm looking fo a centre to keep in with that sort of system, and not out perform it all and scew the sound. Any recommendations? Budget of upto a couple of hundred.
