Hi, I`ve just purchased a a cheap surround setup to go with my widescreen tv. I got from Richer Sounds the Sherwood RD-6103R av receiver and the Eltax Hollywood 5 surround speakers. My idea was to buy cheap now and if the system got well used to upgrade later. My initial immpression on the setup was good, especially with DVDs but rather less so when listening to music (mainly pop/rock).The top and midrange sound quite good but the bass sounds very loose and muddy. Would a sub take the bass away from the main speakers and give me an improvement or is a sub only for the really deep bass end rumbles ? The front speakers left/right are just on thick carpet, is it worth getting spikes or can I somehow `weigh` the speakers down ? Am I just chasing rainbows with this setup or can I get more out of it? Any advise or comments would be helpfull. PS. is there any difference using the coax-digital imput than the optical input on the receiver? Cheers, Disastermaster.
