I need some advice and I am not that familiar with components. My REL StormIII bit the dust and cannot be repaired...no parts. So I bought an SW 12" 400 W sub. Hooked it up with the single cable. Can't say I notice any difference in base at all. I have Klipsch Forte II speakers, center channel and Solid back speakers as well as a year old Onkyo receiver. What do I do to know if I'm getting the base I want and I want base. Thanks.....
