Feature:
Plug and play, 3 buttons on rear to adjust. Nothing much more is needed. Can be daisy chained to other amped speakers. Don't bother trying to hook up non-powered, does not work, I tried. Maybe Behringer will think to adapt speakers so they can amp a non powered too!

Quality:
I have used them at over 25 gigs in the past 2 months without a hitch, Knock on Wood. Compliments from my customers abound. They are plastic, but not scratch resistant. I have banged the crap out of them and they still pound the sound. Great price, great quality!

Value:
By far the one of the lowest priced best sounding amplified speaker on the market with a name that other DJ's and Sound Technicians trust to get the job done.

Desirability:
Very Sleek and Sexy stylish speakers. Just look at them real close and compare to the other more expensive brands. My clients look at these and compliment me on the looks of my rig and my new Behringer B212A's!!

Sound:
Pure and clean, crisp Lows, and Mids, and if you don't want to buy a sub, you don't need too, just put this on your sub output, crank the low all the way to the right and thump all night. My son hooked this to his IPOD direct and plugged into a 120 AC adaptor in his car, he cranked it about 3/4 of the way and the hum was phenomenal. His $1500 system does not sound near as good.

Ease of Use:
Plug and Play! High Mid Low adjust, daisy chain is easy.

Support:
Yes, I have dealt with Behringer asking for advice, I own Behringer Mixers, relays, Power Conditioners, Equalizers, and Now I own these speakers. I have worked with Behringer products for over a decade and I trust nothing else to make me the big bucks! Low price, great products, and dependable beyond belief.

Overall:
If I knew in the beginning what I have learned in purchasing these powered speakers; I would have saved a lot of hassle and money on amplifiers and non-powered speakers. I would have also saved myself a lot of back ache carrying those amps and speakers around. This is a must have for any DJ starting out or just wanting to experiment and see what amplified is all about. ZZounds lets you pay as you play, this is the way to start. I will buy the B215's next, no need for a sub. I hook one of these to a sub output on my Behringer mixer and it sounds awesome. Don't be suckered by the High priced speakers, these are just as good, if not better.

Feature:
Built in Amp is perfect. Built in bass/treble controls. The addition of multiple speakers is pretty much endless too as it has both input and output jacks. Speakers are stackable as well.

Quality:
The only thing I have an issue with is that at 30% power and up the "all in one" features are noticed. The construction of the cabinet does not seem to be sealed and air escapes from around the seems between the front and back halves of the cabinets as well as around the amplifier and all of the connectors (especially the power switch). Although this creates some air sound behind the speakers it DOES NOT affect the performance on the front side of the speakers. Overall, the pro's out weigh the con's which is why I gave it such a high quality rating. I have not had a chance to really work with these speakers yet so I cannot comment on the longevity of them or the actual speaker dependability but from the performance they gave last night I would purchase more if needed. NOTE: As they are a trapezoid configuration KEEP the boxes if you don't have a road case as it makes transportation a lot easier.

Value:
I've heard other very high priced items compared to the B212A's and I am extremely satisfied with the fact that it is less than half the price and 100% quality even though some reviews say that they do not compare to the pricy models.

Sound:
I used the B212a's last night for the first time. I was asked to DJ/KJ a party for 30+ people and was expecting to be in a hall no bigger than 30' x 50' In actuality it was a 75' x 100' hall. Honestly, I was a little intimidated thinking that I would not have the power needed to give a good performace. To my surprise I only needed half gain and you could still feel the kick of a drum at the furthest part of the hall. As far as sound quality I would have to say the B212A's are excellent. I am using a Behringer XENYX 1002FX to control mic's and effects and between the bass/treble on the B212A and the bass/mid/treble on the 1002FX there is enough tonal control to make the speakers sound how I want them.

Ease of Use:
As expected these are trapezoid plastic enclosures so the midrange needs to be cut back a bit to get the "boxiness" sounds out. I have also heard that these speakers do not produce bass adequately but I beg to differ. They do just fine for their size. Of course you're not going to get the sound of a 18" sub but for small club DJ or bar room Karaoke performances these speakers are A+.

Overall:
I plan on purchasing 2 more of the B212A's in the future which should be enough for my needs as 2 alone are quite powerful. I do not believe I will be replacing these with another model unless this model was discontinued. I will not be replacing with another brand. I chose this model based on the price value as well as the number of satisfied reviews I have read about them.
