"great price, big sound"4.0 starson by orinjoseph
Pros: -volume control & frequency control allow for manageable bass
-enough power for a room to a home theatre
-frequency range 25Hz-200Hz
Cons: -requires time to manipulate controls to suite environment
Summary: I purchased CS-315 which came with excellent speakers (D-N7X, 50Hz-100kHz). I placed them on shelves way over head that the bass seemed to be missing. I added SKW-204. It is big and beautiful. I hooked it up in no time. I played a few CDs just to get a listen of what SKW-204 had to offer. It offers a lot! It should be called a sub-whopper! I played around with the volume control to match the room and the frequency control to match the speakers. After a few tries, it blends well into the room. It is unnoticeable. Sounds like it is filling up the room with warm bass. I was hesitant because another reviewer mentioned that it was boomy. Yes, that is true if you decide not to manipulate the controls to your advantage. I am overjoyed that I made this purchase.
