Very impressed with this little speaker. For a smaller speaker, it puts out decent bass, and the battery lasts for a long time. So easy to connect your bluetooth and enjoy. I liked it so much, I bought a second one. I use for outdoor events, and I carry it to many of my networking events, when a microphone/speaker are needed!

Sounds good! Reasonably loud, very good frequency response.

Three issues with the design, which may be deal-breakers in some use cases:

1.) the input jacks are strictly XLR (vs. XLR/1/4" combo, which is common nowadays),

2.) no reverb (if you're adding a separate circuit board for Bluetooth and USB, why not reverb?), and

3.) the power switch has a special position for charging (why?)

For the next edition, I hope Monoprice/Stage Right will consider addressing these shortcomings, as they'd cost next to nothing to implement/resolve, and would make an already quite good powered speaker great.

That said, if all you need is a loud & clear rechargeable powered PA speaker with XLR, Bluetooth and USB inputs, the D1 gets it done, at a good price.

Great, portable product with excellent sound for small settings. I wish I had bought two though. I was very pleasantly surprised to discover that it had its own internal rechargeable battery. When I purchased it, I was under the impression that it required external ones.

I have tried all functions other than using a XLR cable to tie to another PA for stereo. The unit has very good reproduction in both treble and bass. The battery seems to last a long time between charges. Once the power level LED's reach down to the yellow, it will be a short time before the unit will completely shut down. I am glad I purchased this PA system. No complaints.

These little speakers are great for several applications. The true stereo pairing for bluetooth input, multiple mic or line inputs, plenty of level for what it is, sounds great for its size, versatile and good value.

It is a good speaker , good sound , good bass and good treble , I like it

The first one I purchsed the battery was bad and wouldnt charge....Monoprice replaced the second one that needed charging and seems to be ok...which is why I bought it to use where there is no 110 volt outlet...To make this a more versatile unit,I would have had guitar jacks installed as alternates with the XLR inputs so my acoustic guitar wouldnt have to use an adapter to go from 1l4"' to an XLR input. Also a reverb or chorus would complete the deal to make it more usable.The sound itself is wonderful and would recommend this as its portable and has a good output wattage.....Monoprice always has good products and I hope they do improve on this as it would probably.sell more....

These are decent speakers, as long as you are not expecting great fidelity. I was expecting separate drivers, one for the bass and the other for mids and highs. This speaker is nothing more than a coaxial car speaker. Everyone knows that car speakers are not hi fidelity. I'm thinking about replacing the speaker with two separate drivers with better frequency response. The amp is adequate for a battery powered unit. Bluetooth works well and the connections for in and out are quality.

Great for portable sound. Can be linked for stereo sound. Overall, good quality construction

Pretty good speaker
