Pros Nicely designed enclosure, great sound
Cons No cons that I can imagine!
Summary I've owned this for about a year now, and it has never failed to impress me. With my Yamaha HTR-3063BL and some JVC satellites, television, movies and music have come to life. My previous Panasonic HTIB setup absolutely pales in comparison. The bass does require some tweaking to suite the environment. The sound is more than loud enough to fill a large living room. Add this to a great price, and you cannot go wrong.
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.
