RockvilleRBG12S Bass Gig 1400W Active PA Subwoofer 12-Inch, 8-Ohm, Deep Bass, Portable Design, Adjustable Crossover, for DJs and Live Events

I got asked by some friends to DJ for a gig (which I haven't done since covid) and I was missing a few things, a sub being one. I was a bit worried at first because I didn't recognize the brand the price was super cheap. Usually if somethings too good to be true, it usually is. I picked up the 12 inch and this thing did not dissappoint. It's loud and adds the deep bass I was missing. Shakes my whole house up! Hopefully one will be enough for the small gig I have coming up. It's as heavy as you would expect it to be if you've ever handled a subwoofer before. The enclosure is well made and it feels very durable. There isn't too many controls on it so its super easy to set up and easy to use. The sound is clear, I don't hear any wierd buzzing or feedback sounds. It looks like a regular sub. Overall, this is a great buy! Highly recommend coming from a 20+ year DJ.

Ok let me tell you that The RGB15S Active Subwoofer is an amazing little package. I ordered two of these to pair with my RPG12 Active speakers for use at an outdoor festival. The Subwoofers are built very well, the carpeting of the cabinets seemed a little lacking in QA/QC but none the less was effective and clean. The input section is very user friendly and marked in such a way that it’s nearly impossible to not connect these properly. The sound quality is also impressive, I have seen various videos on Youtube that show muffled or distorted subwoofers I am assuming this is because the RGB15S units were not set up property or had signal going to them that was distorted. The playback from the sub at my events was tight and accurate. Much better than I was expecting. On a scale of 1 – 10 I would give the RGB152 an 8-8.5 rating. Definitely enough quality sound and volume for any mobile DJ indoor or outdoor venue.The RGB15S subwoofer has an onboard DPS that is pretty user friendly. Pick a disposition and slide the selector switch to the setting and you’re in business. There is also a onboard crossover with 3 crossover points, again very easy to use, pick your desired Xover point and slide the switch. I have seen many user videos & reviews of these subs that really do not do them justice. The key to setting these subwoofers (or any speaker for that matter) up correctly is having your signal source or controller set up property. Poor signal source = Poor sound.Start with the DSP set to OFF and the Xover point set to 80hz. turn the gain pot on the RGB15S to “zero” (all the way to the left) Assuming your Controller is set up and “zeroed to no more than +3db” (your digital meters are not constantly in the red, only bouncing in the orange and peaking in the red from time to time) connect your sub to the controller and play a track with reasonable bass and at full program volume. (NOTE: YOUR TOP SPEAKERS ARE OFF AT THIS POINT NO SOUND AT ALL FROM THEM). Once music is playing, slowly increase the gain (turn to the right) on your RGB15S until you hear sound coming from your sub. Continue to increase the Gain pot until you begin to hear distortion and see the clip light flash vigorously, slowly turn the gain pot back to the left until the CLIP light only quickly FLASHES on bass notes. Then Turn it a tiny bit to the left more. This should give you a good “live play back” setting on the sub. At this point connect your TOP speakers and adjust their volume accordingly. If the low end sound is not quite right, at this point you can adjust the Xover frequency on the sub, I would recommend lowering the volume when doing this. I have found that when using the RPG12 powered system (input gain set to 5 and unit volume set to 6), the 100hz setting blends the best for most music types. You can also adjust the DSP if you are looking to boost the bottom end but I have found that the DSP seems to distort the sound coming from the subwoofer and 99.9% of the time leave that set to off.I have used TWO RPG12 tops and TWO RBG15S bottoms at outdoor events in 90* Full sun conditions and ran them nonstop at peak volume for over 5 hours with no problems. The amp on the RGB15S was not even hot when the event was over. The NON POWERED pass though outputs provide for easy connection to my RPG12 tops. For the price point I am extremely impressed with the RGB15S subwoofer. The only thing I would like to see on these for the future are “recessed wheels” so you can tip and roll the subs when needed.out of the box I did have one RGB15S arrive DOA. However the Team at Rockville was quick to help resolve my issues. The initially sent me a replacement amp, when that did not fix the issue, they issued a replacement RGB15S for me and set up an RMA and return shipping label for the DOA unit. The whole return/swap took about 5 days.In closing, the RGB15S is a lot of bang for your buck. When set up properly you’ll get good sound quality with tons of volume. On board Xovers and DSP settings add value to the package. Priced at approximately $250each with free shipping (amazon or rockville site) you really cant go wrong.

This review is for 12-inch model.I was hoping to be able to give 5 stars, but unfortunately cannot in good faith. The components are good for the price, but design and build quality are not.Value Stars:Components: 5Design & Build Quality: 3As noted by many reviewers, the amp will overheat. It is not the amp's fault. The amp is installed in a sealed "shoebox" cavity in the box. This would not be an issue if the heatsink was on the outside if the plate. With this design, the amp gets no fresh air and the heat is trapped in the sealed cavity. The way I "fixed" it was to drill out two 2" holes in the top and bottom with a hole saw. Now, when the driver pushes, air will move across the amp, cooling it.Now that the amp is exposed to the moving air in the box, it presents a different issue that some may find unacceptable. The amp plate is not sealed, so now air will push through around the various connection holes. This creates some air "huffing" noise in the back of the box. No real fix except to completely seal with silicone, but then adjustability and usefulness is lost. I used some flat adhesive weather stripping, removed the dial knobs, and poked them through the stripping. I am a Jeep owner, so i have plenty of weather stripping around. 🙂 This does not fix the leakage through the balanced ports, but it is something. A small price to pay for the sub not shutting down in the middle if a gig, due to overheating.Then, there is the box build quality. I had vibration that I thought was the grill. Turns out it was the front face place vibrating against the inset grill frame. This frame connects to the other box walls and holds the driver, so it is arguably the most important piece of the box. The fact that this area was not truly rigid and secure is unacceptable. Do better! I fixed this issue with additional screws through the frame to the face plate.I am not attaching the grill again. It is basically a flat piece of expanded metal, screwed down with wood screws into the thin raw edge of a particle board "frame". It will possibly just be a future source of vibration. This saddens me because part of the draw of this box configuration was the possible extra protection that a grill offers the driver in the case of idiot patrons around my equipment.You take the good with the bad anymore. It does get tiring needing to rebuild and improve on simple designs for manufacturers so you can have something that works as it should.Of course, i may be just too picky, place too much value on my hard earned money, and have too much pride in workmanship for today's manufacturing standards. I just wanted others to be informed before making this purchase that you will need to do some work on this new product to make it truly quality. I hope this is helpful to somebody.
