I was kind of leery buying this since Douk isn't as established as some other brands, but it's turned out to be a great purchase. I live in an apartment but love pro audio, so I have an SVS Micro sub to round out the bottom end, but I miss the immersive feel of that bass vibrating your seat. So I paired this amp with with a couple of the Aurasound transducers, and it's been fantastic. Good quality and responsive, plugged into one of the sub-outs on my receiver. And the controller is very nice, it's an attractive machined metal unit that feels good, with a nice smooth intensity adjustment knob and a satisfying click to turn it on and off. Plus the cable for the remote is USB-C and not integrated into the unit, so if the cable gets damaged it'll be easy enough to replace with another long USB-C cable and not worry about ordering a whole new controller.Only downside is when you do push in the button to "mute" the amp, the LED on the front of the unit flashes incessantly. So that can be annoying depending on where you have the amp placed; it might be better to just turn the intensity all the way down instead. But overall this is a nice, premium solution for using bass shakers if you're willing to spend the money for something specifically dedicated for them. I recommend it!

I've had the time to test this amp connected to two Buttkicker mini's and i will say that this amp powers them nicely. I was concerned that at roughly 57 watts per shaker at 4 ohms in stereo mode that I would not have enough power to utilize the shakers correctly. The minimum wattage for the mini is 50 watts. My wife and I watched 'A quiet Place, part 2' which was recently released and the amp made the shakers quite noticeable. I'm thinking of getting a second amp so each shaker will have it's own amp. I'm not sure if that will be necessary but it is a thought. If I do decide to get a second amp I will update this review.The company behind the amp is also very responsive to any concerns or questions. They contacted me once I ordered the amp to let me know they'll be available for further questions. That to me is a good sign. If someone is looking for a shaker amp I would highly recommend that they consider this little amp. This amp fed by the Marantz AV 10 is a nice combo. I may have to dial back the power on this little guy.

This Douk Audio Bridge/Bass Shaker is an awesome way to take your entertainment/gaming to the next level. This is similar to a haptic vest, only for controlling your bass shakers in your furniture. The installation is easy and can be done by most handy people. I like the built in wired remote for fast adjustments, but I do wish they also had a regular infrared wireless remote controller for when I’m not playing games, but watching movies, since it is stuck in one location most of the time. They add a whole new dimension to your entertainment center.

Currently using this amp to power just two Dayton BST-1 and it does so effortlessly. I have no way to actually measure output, but with these basic transducers, I keep the BSA600 at around 1/3 volume level. The whole unit feels solid and well made. The volume knob has large detents, the frequency knob has (which I'm glad it has) smaller detents and the balance knob has no detents and turns smoothly. And the banana binding posts make speaker wire easy to connect. I know there are measurements posted, but the whole unit looks larger than I anticipated. It's not large, per se, but just larger than the images made me think it was. I'm not using this amp anywhere near it's potential, but it does allow it to run very cool and also gives me room to expand or change down the line. I'm really happy with this Douk Audio amp.
