Douk Audio M1 PRO 320W Bluetooth Power Amplifier, 2 Channel Audio Amp, Wireless Receiver, for Home Stereo Speakers/Active Subwoofer, with Treble & Bass Control/U-Disk Music Player

It’s good quality and works well for my speakers. I like the subwoofer sound output plug. I have dropped it a few times on concrete floors and it still works great. Highly recommend

To being, this little amp is just what I needed for my application. I'm powering two Definitive Technology AW6500 outdoor speakers with it.Pros:Size - This amp is small in terms of amplifiers. It's Class D, so small form factor is the name of the game.Power - The power it puts out is consistent. I have no issues powering my 200w speakers as this amp provides 160 watts per channel.Features - The bass and treble control was a huge selling factor for me. Having the ability to adjust the tone sets this amp apart from others. The knobs have a metalized texture that allows for easy adjustments, even with wet or sweaty fingers. The inputs and source options are a big plus as well.Speaker connectors - The connectors on the rear of the amp that accept speaker wire are decent quality. The screw posts that retain the speaker wire are made of plastic, which seems pretty standard for these amps. I'd suggest using the banana plugs to maintain a more reliable connection, especially if you move the amp from time to time.Cons:Bluetooth - While Bluetooth connectivity was the primary method of connectivity I had in mind when deciding to purchase this amp, the range of the Bluetooth is poor. Most Bluetooth is reliable within 30-33 feet. When having my phone in my pocket and walking 15-20 feet away from this amp, it can cut in and out, and it's solely a BT connectivity issue. With Bluetooth 5.0 technology, I'm not sure an external antenna is necessary, but it's worth noting that this amp does not include an external antenna.Overall, I'd recommend this amp to anyone looking to power accessory speakers like bookshelf speakers or outdoor speakers. I have not used it in a home theater setting, but I imagine if your setup is compatible with the ports on this amp, it would work well. The Bluetooth connectivity issue I mentioned is manageable (which is why this amp is still getting a 5-star rating) if you leave your Bluetooth connected device nearby, but it's definitely something to be aware of if you plan on being at the outer reaches of the Bluetooth connectivity range.

I used 9ft of 8-gauge electrical wire each from the subs to amplifier. For the subs, I used two Dayton Audio SD215A-88 8" DVC Subwoofer's (Power Handling 80 Watts RMS /Power Handling MAX 160 Watts) and a Bbox E8DV Pro-Series 8” Dual Vented-Divided Subwoofer Enclosure for this build. My sub grills are coming in tomorrow DS18 PRO-GRILL8 Speaker Covers. Total watts at 100% volume on amplifier 320watts at 160watt max per sub combined. I unfortunately had to request a replacement amplifier on the day I got it, as it was a Dead-on Arrival (DOA). The DOA amplifier had power but no volume both Bluetooth and RCA. I knew for sure I had my connections all good and my suspicions of a DOA amp was confirmed when I tried it with my older spare amplifier and speakers worked. Now that I have my replacement amplifier up and running the subs sound good that it vibrates some of my garage.

I just bought the Douk Audio M1 Pro. Has anyone connected a powered subwoofer to this unit. And if so, can you recommend one that worked for you.

Excellent sound quality and works well with an active (powered) sub. The Bluetooth 5.0 quality is excellent, even with no antenna (which makes it look slightly sleeker than those with - personally I don’t care). The range from this Bluetooth 5.0 unit without an antennae is about the same as other brands that have antennae’s and Bluetooth 4.2. That’s nice but from what I’ve read about Bluetooth 5.0 range - if they had an antennae on this the range theoretically would have been phenomenal.Was getting the odd pop and click once every couple of hours - until I got a one piece 3.5mm to 2 x RCA (don’t use adapters, use a one piece).Returned my Foster Audio (without sub out) which was also great quality. Both sounded and looked much the same. But I had a spare powered subwoofer sitting around in wanted to use, which adds significantly to the sound quality for me.Lastly, also like the control switch selector from BT, RCA and Off. Other units can be auto switching, which can be beyond annoying. Whichever one you end up buying, look for a switch to control that functionality.

This is a fine product but be aware that there is no way to reduce the treble or bass, just a way to boast. That makes this amp unusable for me.

This review is written primarily based on the price. If you want better sound, you will pay a premium price. For what you are getting here, this thing is great! Nice lows, nice imaging... really nice within it's category. I've never had anything under $500 that sounds as nice as this!

The old (and quite expensive) Harmon/Kardon receiver/amp I've been carrying around since the late 1990s had been living out it's last year at the little gym my wife & I own, where it slowly died. It was a workhorse, and served its purpose well, but I when it came time to replace it, my gym didn't need all those bells and whistles. What it needed was something very simple - analog & bluetooth input, powerful stereo output to run several gym speakers. This little gem came highly recommended, and it turned out to be perfect for our needs. It's elegant - simple dials and switches, no useless menus or screens, not an inch of waste in its compact design. It's even smaller and more beautiful in person than I imagined. And, boy howdy, it puts out a lot of sound. Douk knows what they're doing - if you need big stereo sound in a small package, I could not recommend this little dude more.
