So far I've still not used all of the inputs or bluetooth features of this device. But what it has delivered is far better than anything else in the same price range, hands down.
I only gave it a 4 star rating because to use it as a floor monitor the cabinet isn't angled enough so you must wedge it with a block of wood or something to get it to the proper angle.
But I will probably buy a second one and put them on stands instead.
Monoprice has always delivered great product at amazingly low prices.

I got this speaker to use with my Roland TD27 electronic drums. It works great! Prior to buying this SRD212 I had purchased a different "budget" brand from that big box store and it performed terribly. It could not handle all the frequencies that drum sounds put out. THIS stage right powered 12" works GREAT! It easily handles the electronic drums. Kick sounds punchy with boom and all the cymbals, snare sounds and toms shimmer and sing. The key setting is the "FLAT" eq on the back of the speaker and then minor tweaking in the Roland module and I have great drum sounds that blast out from the kit. I use it in practice AND performance. So not only are drums mixed through front-of-house pa, but also come off the stage with this awesome speaker. I've also used the Bluetooth to play music during workouts and in my backyard when friends are over and the sound quality and fullness is just great. Glad I got it, might buy a 2nd for stereo drums!

I have to say I was a bit hesitant buying these speakers. The price was great but worried about the performance. I was surprised how good they sounded. Very clean and powerful. I'll be using the 12" as stage monitors. They get more than loud enough. They could do the job as FOH mains in small venues as well. Great price and value.

This thing has limitations. The bass is lacking you will need a subwoofer. I hooked up a small JBL sub sounds fine. These speakers are not 1200 watts RMS I don't event think they are 400 watts RMS if I had to guess I'd say around 250 to 300 RMS because they peak out rather quickly. I got the 12" version had problems with one of them being blown right out the box which was surprising but issue was fixed. Bluetooth is nice but does not do stereo you have to use output to send to other speaker then adjust volumes. I was using output for subwoofer so have to pick and choose which one to run; For cost it's fine (if you want to use as home DJ Speakers) Maybe mid field monitors on a budget. There is a lack of bass though. So Subwoofer is a must IMO.

Great speaker. I ordered the 10" model but it was out of stock. After a delay, Monoprice sent me a SRD212 instead. Works great, lots of headroom. The Bluetooth feature is clean with easy connection.

I wish it had adjustable EQ, but its not a major issue.

The absolut best bluetooth speaker on the market! If your buying JBL, your paying way too much. Had a visit from the local police the first time i used it! JUST ONE SPEAKER! Will be buying a second one soon!

I love this speaker. It stands about 3 feet tall and has an amp and is verry loud! I couldn't believe it from the size of the picture and what I actually received. This speaker has 3 handles and is portable and I can connect it to all my bluetooth devices. This is the most awesome speaker I have every owed.!:)

Absolutely Fantastic

Background: I am not an audiophile, nor am I using this speaker for anything other than my personal use. I have a small studio in my home and I tinker with music of all kinds.
I use near-field monitors for everything and had been considering a PA speaker or an FRFR (full-range, flat-response) to use, essentially, as a guitar cabinet.
I am not a performing artist, so I just couldn't justify the typical $700 starting point for a true FRFR cabinet which lead me towards PA speakers. I shopped around my local
music stores, researched, reviewed, and compared all of the different PA speakers out there.

I came away with the following requirements:
- Blue-tooth...Once I learned that some PA speakers include blue-tooth connectivity, I knew that was something I wanted
- Inputs...I have already mentioned guitars, but I also have a small electronic drum set. Having 2 XLR inputs allows me to run output for guitars and drums.
- Power - at 1200W this thing is 3X more powerful than any almost any other PA speaker at this size and price
- Build - I won't be hauling this thing around to gigs, but wanted something durable with handles for easy mobility.

After deciding these were the features most important, the Monoprice SRD212 seemed like a no brainer. I only wanted one speaker, I don't use it for live performances, it has blue-tooth,
multiple inputs, and way more power than any other 12" PA speaker under $500.

After about a month of use, here is my feedback:

- Blue-tooth...This is a sweet feature. I took the speaker out on my back padio this past saturday and was blown away how well this thing sounded.
It sounded like a DJ was set up in my backyard.

- Inputs...I am indeed able to run my guitars and drums through this thing. I just wish I could play both at the same time.

- Power - To be honest...it's way too loud for the little room I use, but it 100% serves it's purpose as an FRFR for my set up.
It provides a completely differnt listening experience than near field speakers and I now have the ability to hear both.
If I ever decided to play a gig, I now have a 1200W stage monitor.
The blue-tooth, power, and portabiliy of this thing have given me a sweet solution for outdoor music

- Build - It's built like it looks. I love the closed mesh metal cover and the rest is solid, durable plastic.
There are handles on 3 sides so moving it around is relatively easy given it's weight.
The design allows you to lay it on either side like a studio monitor or upright like a typical PA speaker.
The bottom has rubber foot pads and the insert for speaker stands.

For the price, I feel like I got way more than I paid for. I purchased this speaker to use as a guitar cabinet and it is perfect for my purposes
in that department. I've made sure to set it up so that I can quickly move it when needed. The next time I get invited to "the shed" for an open jam, I'll now have a great option for
cabinet/monitor. I know I'll also be using it outside this summer instead of the horrible WiFi speaker we've been using.

I am really pleased with this speaker. Thanks MonoPrice!

I purchased two 15" cabinets 3 months ago & those worked out great as on stage drum monitors. I purchased two 12" for stage front vocal monitors & the clarity is as good as any $500 cabinet I've heard. These will be going up in price quickly from the reviews and personal use satisfaction musicians are having using them!
