Rockville Titan Slim D8 Black Dual 8" Powered DJ PA Deep Bass Subwoofer

Update to sub pole issue (see initial review below). Rockville is sending me a replacement Gaspole-B M20 that works with the Titan Slim D8. Apparently, I had the older model. Therefore, I am amending my review to a 5 star review. I already said the D8 sounded good and I used it for another day with further mixer EQ (Behringer Flow 8) and was further sold on what you could do with this compact subwoofer. For, its size, with proper eq, it filled my 1,970 square foot basement without clipping. No chest pounding bass, but it was loud enough with a tight bass that complimented my QSC CP 12 speakers perfectly. So, if you want something easy to use and can adjust EQ from a mixer (no bells or whistles on this Sub but great tight sound), I highly recommend it. I like it so much I bought a second Titan Slim D8 and will put them to work at a company Christmas Party. Thanks for doing the right thing Rockville. OLD REVIEW I received my Rockville Titan Slim D8 and noted it was packed extremely well. The dual 8 subwoofer only has one handle but that isn't a big drawback. I then plugged the subwoofer in to test it out and run some decibel testing (DBA and DBC) to see how loud it was. Used QSC CP 12 Top Speaker in Dance Mode with subwoofer out so the QSC bass would not overwhelm the Titan Slim D8. The Titan Slim D8 sounded pretty good and hit over 100 decibels in the DBA Test and around 120 decibels in the DBC Test. AND THEN I attempted to add subwoofer poles and noted neither my Rockville air assist 35mm nor the air assist M20 worked with the pole cup. I tried a couple other sub poles I had, and they didn't work either. The pole holder was too wide and shallow for the 35mm pole and the M20 was to fat and wouldn't thread into the cup threads. The subs advertise you can use either a 35mm or the M20 for your sub pole. I contacted Rockville who indicated a different model pole would work but now I would have to shell out more money and the pole recommended did not have air assist. So close to being a great deal but now I will need to change out the cups (available on Amazon) myself so I can at least use my M20 air assist pole for the Top Speaker.

Just like Dusty, I paired this with my little Alto Busker, along with two little speaker-poles, that screw together for double the length, much better than any adjustable version with plastic knobs. The sub is GOOD. Like REALLY good, and verified to actually be 400 Watts too on as it draws that much during hard hits from my power station. Specs say it goes down to 30 Hertz, and I can attest that it moves a LOT of air and smoothly reproduces low frequencies way down low, without any boomy resonant frequencies to muddy the sound. These dual eights are TIGHT and PUNCHY, to say the least. Cabinet construction is plywood, with a very nice truck-bed-type rhino-lining coating. I removed the grill (four nice threaded bolts) and both drivers to inspect the quality. The drivers were quite impressive! The magnets are nearly as big as the cones, and weigh a lot, 50 oz magnets, I believe. There is no adjustment for crossover frequency, but it does sound like it’s set at about 80Hz, and I just crank it all the way up. I watch the input level LED and it does not clip until waaay past where I think it should. I’m constantly super-impressed with the performance of this little (50 lbs) guy. I do wish it had another handle though. If using only the one integrated handle on the back, the unit tips forward as I lift it and scrapes the bottom-front on the ground…. Once I realized this, it’s easy to avoid, but that one handle makes it awkward to carry. Also, the description says it has dual-use speaker-pole-cups, but I found them only to be compatible with the MN20 threaded types. My 1-3/8-inch (35mm or 1.375”) poles were just loose and didn’t work, so I bought the M20 threaded poles and they work wonderfully, so solid and secure. It only consumes about 30 watts at idle, up to about 40-50 dB, so just chillin with that low-end bumping, lasts 11+ hours on my modest little power-station of 350 Watt-Hours. It’s so solid that it provides such a sturdy base for my cute little Alto Busker Speaker, and they’re nearly the same width, so it looks great. (The Boze S1+ Pro is dang near exactly the same width, so it looks slightly more better with this sub) I appreciate both XLR and RCA inputs, as botht

While I haven't used these out on gigs yet, the price and value of these seem to be pretty great. I was getting ready to buy some weighted stands for nearly the same price so I added these to handle the low end of my main PA tops. These punch way above their price range. I don't expect these to keep up with my high-tier tops, but they bring in enough 55hz and lower bass they extend the tops without needing a dedicated sub, even at higher levels. I'd love to see these with some more options on the amp. A sub HPF would be great. These get down to a usable 42hz. If the amp removed anything lower these could serve as a great mid-bass unit with dedicated bigger subs. These are Amp limited, meaning you'll clip the drivers before any limiters kick in. You will hear this very clearly. This is expected with lower end equipment like this but if you understand your systems limits these will do good. The other benefit of these is you could run 2 unit per top and get a theoretical 126db per pair. The modularity of these, with a small footprint makes these a win. I'd love to see other companies expand this area, smaller dual 8s but for now Rockville is the only one out there worth anything. At ~$270 each , these have great value.

Did not meet my expectation

Update 3/29/26 I still live this thing . It is the perfect complement to my garage system. It actually SOUNDS GOOD. In my previous comment I complain about my main kicker speakers but I now realize they just needed something to compliment the bottom end. The system is a hole sounds actually quite impressive.. I bought this with absolutely no expectations whatsoever except expecting that they may return it because I might hate it. The opposite is true. I've only used it for a couple days but I think I really like it. I purchased this knowing it was inexpensive. This is for a small system in my garage where the summertime heat and humidity and winter time cold would be problematic for a higher end subwoofer with a cabinet probably made out of an MDF material. So I bought something I wouldn't really have to care about for this application To my surprise the fit and finish is quite good for what is supposed to be more of an industrial use product. So far I am pleased with the sound quality. Like I said this is just a cheap garage system I've thrown together to Make my shop a little more entertaining. I have a paired with a couple kicker outdoor speakers ( which honestly sound very terrible ....). I think if I replace the kickers the whole system will sound very good....... Very good for a garage..

It's a really good sounding subwoofer. It sounds really punchy and it's heavy and it sounds pretty clean with the Bluetooth. I have to see where the mixer but so far it sounds good and it's heavy solid wood

I've been a mobile DJ playing primarily weddings for 35 years. I have been in the market for a small footprint sub to add to my setup for quite a while. Space is at a premium in my truck, so I wasn't interested in a 15" or 18" sub. This Rockville TITAN SLIM D8 did the trick! Small enough to put under a table. In fact, I was so impressed I bought another one and will use them flat on the ground as bases for my tops. For $300 you will love this little sub! It's not chest thumping bass, but it will fill out the low end very nicely.

Good product but DO NOT order this from Audio Savings! Their shipping is horrendous!!!! It took 8 days to arrive. That is unheard of today!
