Rockville Rock Shaker 6.5 Black, 6.5" Powered Subwoofer, 250W, Deep Bass, Class-D Amp, RCA Inputs, Perfect for Home Theater & Studio

Big sound small speaker. I am using it for my surround sound. Shakes the floor!! Sounds great especially for the price.

I know high quality subs. Have had Velodyne, Kilpsche, and JL subs in my cars for years. Just needed to add some low end to my Sonos run den ceiling speakers. I normally listen at a moderately low volume, but sometimes go to a moderately loud volume. You’ll need a bigger more powerful sub if you’re really trying to crank it. But for the listening levels I’m doing could not be more happy with the quality of the low end. We’ll have to see how long she holds up. Make sure to set the volume and EQ filter at your max listening level to get the most out of it without distortion.

Phenomenal product. Incredible value. Would highly recommend.

So, gonna be upfront right away and say that I haven't been able to put this subwoofer to the test like I've wanted to. My current living conditions (with "others" living in close proximity) have not allowed me to really play and let it loose...However, with that being said, I will definitely give this Rockville Rock Shaker 6.5" subwoofer a solid 4 stars. Actually, if Amazon allowed for half-points, I'd likely give it a 4.5 stars. Solid (enough) construction. Knobs feel a little flimsy, but I've been gentle with them. Happy with the connection options on the back.My setup, currently, is running off of a Dell G5 gaming laptop using the 3.5mm headphone jack.The 3.5mm cable Y's into L/R RCA cables which I've connected to the subwoofer's L/R "LINE" Input. From there, I have connected a pair of Edifier R1280T bookshelf speakers using RCA cables out of the the subwoofer's LINE OUT connectors.The room I'm in is quite small. Maybe a 13X13 ft. bedroom with laminate flooring (no carpet). The subwoofer is located about 3 feet from any wall or corner (just because that's all I have to work with).With all that being said, here's what I think (thus far)...My initial impression wasn't great. My first couple of uses with it left me feeling concerned. With both the volume and crossover knobs (on the Rocker subwoofer) set at 50% it sounded VERY shaky - like rattling in a NOT-good kinda way. The bass seemed distorted even at a low volume. But, hang in there...It gets MUCH better.For the next week or so, I began playing with different settings (on both the subwoofer and the Edifier's). I also left the volume on the laptop fairly low so that the subwoofer could "break in" if there is any truth to that theory.Tonight? A couple of weeks later? Thankfully, there was no one else around the house except for me...So, I had an opportunity to push the volume a bit and see what I could feel/hear. And I was extremely pleased. Tight bass...The Rocker filled in the lower notes beautifully and had me enjoying my music once again. **This was after a good deal of tweaking between the subwoofer and the Edifier's, because the bookshelf speakers also have bass/treble knobs).Right now, I think that I have found the perfect balance between the two, which is:Dell laptop volume set at 50%Rockville Shaker 6.5 frequency crossover knob set at just below 50%Rockville Shaker 6.5 volume just a hair over 50%Edifier speaker volume set at an estimated 50% (can't tell for sure as the control knob isn't labelled and has no tactile fell to it)Edifier bass completely turned down.Edifier treble (high frequency) set at about 75%With all of this messing around? It sounds really sweet tonight! And I'm quite pleased with my purchase.Down the road? Here's my thoughts...Will I keep this 6.5" and eventually integrate it into my home theater 5.1 surround sound system using my Yamaha receiver, JBL 8" bookshelf speakers and a Paradigm center channel speaker? Yeah, I think I would definitely consider that...Or, will I take the Rockville 6.5" subwoofer along with the Edifier bookshelf speakers and use those on my ramped up gaming PC? And, then, snag a, 8 or 10" subwoofer for my home theater setup? Yeah, I'm thinking that this will be the case.IF this Rockville 6.5" subwoofer continues to provide great bass like it currently does? In the future, I wouldn't hesitate to try one of their larger versions as an addition to my home theater setup.For the money, this thing feels like a really good "buy".

A++ little powerhouse. Added this into my high end Rotel system. System has 4 tower speakers and one sub. Needed a little more kick in the room. This delivered. Most bang for buck and size.

I was really excited to use this in my office but it didn't work - no power. I returned it with no issue. It looked nice and felt very solid but it didn't work. Unfortunately, I needed a Y adapter for this subwoofer. It was $10 and Amazon charged me $7 to return it. Other than that the return went well. I really wanted this to work but I am going to buy a more familiar (and expensive) brand instead.

Remarkable sub woofer. Needs very little input.

I received Klipsch R40PMs for Christmas, and while they sound great, they were definitely missing the low end. Since they’re smaller speakers, I didn’t want a big sub, and since they were pricey, I didn’t want to spend a lot. I quickly found this sub and thought it would be perfect. After receiving this Rockville, I hooked it up right away, and was somewhat impressed. After moving it to the corner of the room, I can’t believe how much sound it puts out, and how deep it will hit. For comparison, I have the Klipsch RP 600Ms with a Klipsch R120SW in my living room, and this little sub will give my 12” Klipsch a run for its money. I am playing my smaller system at lower volumes, but it sounds absolutely amazing. The Rockville sounds like it’s delivering lower frequencies than the Klipsch, albeit at lower volumes, which is all I needed. I highly recommend this sub if you’re looking to fill out a smaller bookshelf system. Extremely happy with this purchase!
