RockvilleRock Shaker 10" 600W Powered Home Theater Subwoofer, Deep Bass, Adjustable Crossover, Compact Design, Perfect for Movies and Music

I purchased the sub for my son after he ditched his floor speakers and went with upper end bookshelf speakers. I have the same setup, 2 bookshelf speakers and a floor sub. Made an incredible difference. I'm not a huge audiophile, but the sub + bookshelf speakers is a great pairing. This not only gives great bass, but fills in the midrange quite well. This subwoofer is solid. Reasonable price for a clean bass addition. It does have phase control for multiple subs and volume/power adjustment.

Connected this in between two 100w powered speakers, and everything sounds great!

I purchased this speaker to replace a 13 year old polk sub woofer PW 111 that quit working due to a lighting strike. I was just going to replace the electronics, but I could buy this speaker for about the same price and it is a 10 inch vs 8 inch. So glad I purchased the whole speaker! This subwoofer sounds great with my system and I have no complaints. It has such a nice deep base for my listening preference. I'm using an old Yamaha home theater system with dedicated subwoofer ports and my old ears can tell this replacement has a richer sound that what I had ! I am not an audiophile but I LOVE IT !

I ordered the 10" Rockville to pair with my Paradigm Atom speakers. The Paradigms are excellent speakers with good definition and clarity, but they can't get below 50 Hz. or so. I bought the 10" sub because I knew that anything smaller would just muddy up the upper bass frequencies. I set the crossover control all the way down at 50 Hz. and set the volume to about 1/3 - 1/2. I was very pleasantly surprised at the performance, especially at low volumes. It's nice having that last octave and a half back after using these Paradigms for about 2 months.I've read some bad reviews here for this speaker. I've also seen pictures here of a speaker completely blown out of the cabinet and I can't help wondering what these people have left for hearing! I wonder if these are the people that drive down the street in Jeeps with 5000 watt subwoofer setups shaking everyone's dinner plates within 6 blocks. If so, that would explain why they can't hear.If you have reasonable hearing and have a clue what to do with a subwoofer, this is an inexpensive addition to any small speaker setup that needs a little help on the bottom end. It comes with low-level AND high-level inputs/outputs so you can hook it up to most systems with no additional parts needed. I hooked mine up using the high-level inputs/outputs and had it set up in minutes and playing some demanding tunes.The reason I subtracted a star is because of the crossover control. It doesn't really behave like a true crossover control in that it's more of a shelf control. It seems to only affect the frequencies passed to the subwoofer and not the frequencies passed to the main speakers. If you turn up the frequency too high, the bass starts getting real muddy with the main speakers covering much of the same frequencies as the subwoofer. It's not a deal breaker in my case because I have it turned as low as it can go, but may be of interest to others. I have not checked the behavior on the low-level inputs/outputs so I don't know about them.The construction seems solid and it works well with it's auto-off function turning the speaker off after several minutes without signal. It removes the need to pull out the speaker to reach behind it and turn it off when not using it.I've only had it a few days so if I have any problems with it I'll edit my review, but for right now it's 2 thumbs up.

It doesn't produce bass, rather an annoying popping sound. The speaker is absolute junk!

Nice quality sound and product. Sounds better than my 12" Polk subwoofer with also more watts.

The speaker arrived in good time. It was packed well. It produces good quality sound. We are very happy with this purchase.

Packaged very well and hooked it up very easy to connect ,sounds great already.
