I just bought a new HT setup (see sig) and moved my old setup into my bedroom. The sub I had for the old setup, Onkyo SKW-204, left much to be desired but it fit perfectly in my space challenged living room so I figured I'd leave it there for the time being and just buy a new one for the room. I didn't want to spend much money at all so I decided on the Sony SA-W3000 for $129 at B&H Photo Video. Not gonna lie, it was extremely hard for me to spend the money for this sub because I kinda felt that if I were to spend a little more that I could have a better sub. While that is still applicable, I have to admit that I got way more sub than I anticipated! When I first unboxed it and seen how big it was I was taken aback. I didn't realize it was as big as it is, but that wasn't necessarily a bad thing. My Onkyo sub is 8", this one is 10", and since the Onkyo had a hard time filling my large living room I figured I'd probably have better luck with the Sony....the fact that it matched the receiver was a plus too So I kept the Sony for the living room and put the Onkyo in my room. When the Onkyo was in the living room I'd have to have it's volume maxed out and the sub output level on the receiver maxed out in order to get any decent output from it and even still it wasn't satisfying. Now that I have the Sony, which is 50 watts less than the Onkyo, the volume knob is only 2/3 up and the sub level output on the receiver is at 0 (range is -10 thru 10) and the output is incredible! I'm knocking pictures down on the shelf that's right next to it and rattling things throughout the house! SQ wise I have no complaints, it hits low, hits hard, and has excellent cone control and it fills up my living room with ease. My expectations for this thing was about as low as could be, I was already planning a DIY sub build but after hearing this thing I am scrapping the idea. I am satisfied and then some with this sub and highly recommend it to anyone looking for a decent sub on a very low budget.
