Rockville Rock Shaker 15" Powered Subwoofer, 1000W Peak / 500W RMS, Class-D, MDF Enclosure, RCA, Speaker Inputs, Phase & Crossover Control, Black, for Home Theater & Studio

A little background history I've been dealing with audio since I was 14 years old and I'm now 39. So I've had my experience for quite some time in audio, not only upgrading receivers, amplifier, speakers and especially subwoofers over the years from basic home speakers in a box (cheaper one) and jumping price ranges all the way up to 2k or a little more. And from standard subwoofers that lack an amplifier and powered subwoofers, of course. I have to say this is completely worth the money. I do want tp clear up a couple things that might be causing people to hold back or possibility they're setting up their unit incorrectlyRockville gives a really good explanation with only maybe four or five pages on how to set up your receiver and subwoofer including the connection but it also has a QR code with a link for a video if that's more of your thing.It's actually much better sounding than any of the units I ever purchased when I first started getting into audio. It packs a punch and what's more surprising it's $250 all the way up to $300 and sometimes you can get them on special for $230. These are very good subwoofers for starters. They're basically the equivalent of when I first started audio of a unit that was considered middle/high-end brand, but still classified as a middle type of subwoofer packs of punch, deep powerful, and good but affordable. Keep in mind the back then you were spending anywhere from $500-$700 for a medium level type of subwoofer. (which it was very expensive back then) so getting these completely worth the money.It's a party subwoofer.I was skeptical first but they deliver and was surprising it delivered good quality for the money. Keep in mind. My last subwoofer was $1300 when it first came out that was double the size of this unit, the same 15 inch sub but was constant 600 Watts RMS (constant) and 1000+ in peak power. It can hit extremely low bass and hits notes under 20/17hz. While the Rockville caps at 30hz (still good btw) for the price you can't beat it. I would consider it to be a compressed tank versus the more expensive subwoofers are massive tanks if that makes sense? I'll upload some images so you could see. It's basically the same size or a little bit higher than a standard small table for living room. (sitting positioned by your arms on a couch)I'm going to label a few talking points with numbers! Skip those if you're already familiar with audio and know how to fine-tune and set things up yourself.#1It's pretty straightforward. It has multiple ways to connect but the way you want to connect these for a home theater is use a sub/coaxial cable + Y splitter.. (instruction manual says this so clearly it's required versus optional on other subs)#2The instruction manual and I'll upload an image specifically says that it does not have an LFE sub connection, which means low frequency effects and it's suggested to use a Y cable splitter: 2 males to 1 female type. So make sure to have one of these handy. You can buy a cheap one for about $7/10 or a decent one for 12/15 bucks but practically any one of them will work just make sure that it's nicely built and not one of those rubber ones that looked like you bought them in RadioShack for two dollars. lol#3Connect from your subwoofer out which either has 1 RCA connection or an LFE for the subwoofer, and then on the opposite end add the Y cable (2 male plug RCA into left/right) on the subwoofer. Basically, forcing the subwoofer cable from one plug-in RCA into a double into the subwoofer.This normally adds extra power at lower volume levels to the subwoofer, giving it a boost of about +3 and then some other subwoofers +6. I can't comment on the boost because I'm not familiar with the components, but I will say it gives it a +3 and extra power at lower volume levels. I'm not getting into back-and-forth on the never-ending Y cable argument, but the instruction manual specifically says to use it versus other subwoofers will say to use LFE and 1 line. Also crank the crossover in the back of the subwoofer to 150 which is the maximum. Then set all your speaker crossovers on the AVR to 80 Hz so that it sends the majority of the bass of the sub itself. (EDIT 2 60hz for tamed bass more in edit section at the end)#Build QualityConstruction of the subwoofer itself is very basic, like a standard classic subwoofer box. The woofer is decent and the amplifier packs of punch. For what you're spending it has very good functionality and flexible.#Negative (not a negative)The warranty is one year but take the consideration a lot of $800 to even $1500 subwoofers nowadays only have two year warranty on the amplifier itself considering the price of this subwoofer you can easily replace it for 1/3 of the price if it came down to it. TThis isn't a negative but some might perceive it that way, but really it's not when you do the comparison.EDIT: 2:OK after having the sub for a while, yes it does have a habit of getting boomy depending on the content and your set up. If you follow my instructions, everything should be fine, but if it's still overly booming lower crossover on the AVR subwoofer 60hz Hz rather than my originally recommended 80hz. To get less of the midbass and then adjust the bass to your preference on your AVR and on the subwoofer knob itself.I found out that doing this. I can keep the power of the sub for itself in the middle, switched the crossover point on the subwoofer in the AVR to 60 Hz and then tame the bass. If I wanted more base simply increase it on the AVR if you originally had it at a negative it all depends on your subwoofer settings on the AVR in combination with the sub. I originally with 80 Hz AVR at -5. I can now increase it to -3 get heavy bass but it's not overwhelming. It mixes with everything. (better in my opinion) if you want even more just simply inclusive to -0. But remember to keep the sub knob for itself in the middle. This will give you enough room to play around with your subwoofer settings without overdriving the sub itself.

My meticulously crafted 11.2 Atmos setup was already a sonic marvel, delivering earth-shattering bass that shook the very foundation of my room. Yet, I couldn't shake the feeling that something was missing, a subtle deficiency in the rear of my listening space. The absence of woofers in my rear speakers left a void that demanded to be filled. That's when I decided to take a chance on the Rockville Rock Shaker 15-inch subwoofer, and I'm absolutely ecstatic with the results, especially given its incredibly affordable price. Positioned strategically behind my couch, this beast of a sub lives up to its name, vibrating the entire seating area with intense, low-frequency energy. Despite being ported, unlike my existing sealed Definitive Technology subs, I haven't experienced any conflicting resonances; in my room, all the subwoofers work in perfect harmony. The sound was impressive straight out of the box, but after a few days of intense use, filled with movie marathons, the Rock Shaker continues to improve as it breaks in. Watching films like "Sudden Death," "Deadpool & Wolverine," and "Rampage" has become a truly immersive and visceral experience. Not only that, this subwoofer also shines with music, effortlessly reaching the lowest frequencies. I'm honestly baffled by the negative reviews; as someone who appreciates good audio quality, I find its performance remarkably impressive for the price. I especially disagree with anyone who claims this is better than a 10 inch, they must have placed it wrong or it is defective, because I do not agree at all. As long as your expectations are realistic, and you're not anticipating a $2000 performance from a $200 unit, I'd wholeheartedly recommend this subwoofer. It even includes both high and low-level inputs, a feature often found in much higher-end equipment. Though delivery was a bit slow, the wait was ultimately worth it. The only minor peculiarity I've observed is that the sub seems to power off immediately when the signal stops, rather than adhering to the 15-minute delay stated in the manual. Whether this is unique to my unit is unclear, but aside from that, I enthusiastically recommend the Rockville Rock Shaker 15-inch subwoofer to anyone looking to boost their low end or add a powerful rear sub to an existing system.

Everything looks awesome till the minute you start bumping music at high volume, speaker box will bounce around and speaker will distort very bad. Don't recommend this speaker.

15 inch hits pretty hard for the price. Took a few hours of music to break them in. Its labeled volume knob, its a clearly a gain knob. Kind of stuck with one spot.I found these arent great at playing 70-80 hz. Try setting the onboard crossover to 60 hz and use a full stereo rca 'out' instead of the dedicated 'subwoofer out' channel.

I bought this to show my 4 year old nephew what dinosaurs sound like. Also, I enjoy annoying his parents. I succeeded. This thing is loud and had the windows in the house shaking. The final resting place for this speaker is in my garage to give me the low end I need for my six car garage.In the picture you can see the difference in size between the 8",12", and 15".I also ordered two 12" active subs but I don't think I will need them. Maybe I'll have to build a theater 🤔. I have tried the 8", the 12" and the 15" Rockville shakers. They are all pretty awesome for the price. For a home theater I think two 8" would be amazing. I never thought I would say this...but I thing the 12" and 15" are too loud if you have neighbors. I have 2-12" cerwin Vegas in my car and I love them. But I don't sit out in front of my house and bump them. I annoy strangers for a brief period of time. If I had a basement I would put 2-15's down there and rock the hell out of them. They are clear, responsive and very cheap for the amount of air they move. I am very happy, my nephews parents are not.

Has port distortion. Added the proper poly fill. Sounds like a different sub. Actually worth the money after the poly fill upgrade
