I am looking at a couple of Subs. Price is ranging from uros 300 to 700. The biggest it can be is a Q100, smaller is even better. Hope some can help me. Yamaha 320(350)... cheapest option. Lowly rated by HCC, while What Hifi gives it 5stars. What gives? Is this the biggest bang for the buck? Rel Quake(399)...cheapest Rel. Not highly rated. Still nice size. Yamaha(599)...overblown numbers, but i don't really need 800 watts. How good is this sub?!? Infinity HSP500(599)...anyone familiar with this model? It has a 8" woofer and 500 watts. Are these numbers for real? Anyway how does this subwoofer compared to the Q150 and Yammy 800. Rel Q150(699)...top of the line in my budget. I loved the Q100, how does this little guy compare? Teh size is actually perfect? Unlike the Q100 this model doesn't seem to be a undisputed winner. Hopefully you can help me with my choice.
