Feature:
No features. Power cord and no slip stick on surface for bottom of speakers included. Back inputs are 1/4 or XLR, neither of which are included. Wouldn't expect that, but would be nice. Agree with the other reviewer here, the tweeter needs a grill or protection. The 'woofer' is kevlar and very sturdy, but the silk dome tweeter looks like it could very easily get destroyed.

Quality:
Nice weight, volume knob and on/off switch are very solid. Slick black surface and kevlar woofer look nice, and the connections are all very solid. It definitely feels high quality and durable.

Value:
Compared to other monitors in it's price range, there is no doubt that the BX5 is the bang for the buck.

Desirability:
Basing speaker purchase on aesthetics is idiotic.

Sound:
The sound is very detailed, and crisp. There are no muddy spots, and everything comes through very loud and solid. The highs sound great, and bass is not lacking. The 5 inch low end speakers will put out enough bass to shake my desk and rattle loose objects. I only have lower end monitors to compare with, but I have heard many different speakers, and these are most definitely clear and excellent sounding.

Support:
Haven't dealt with them.

Overall:
I'm sure I will own these with a possible sub upgrade, but they have plenty of bass for everything. When I do upgrade it will be because I can afford much much more, not because they lack anything.

Feature:
the ability to tune them to your listening environment is really the only feature other than good drivers that you can ask for. ohh, the little blue light is a nice touch too.

Quality:
mine have ripples in the vinyl that covers the box at the corners--not enough to cry about unless you are truely a perfectionist. also, one arrived with a tweeter dome collapsed--i used some scotch tape to pop it back out and it's been fine ever since. also, mine have been on since i bought them except for when i'm on vacation and no problems yet.

Value:
the pair are a pretty good value--add the sub-woofer and you've got a great monitoring system for $500.

Desirability:
at the time i bought these there weren't many choices in this price range. i'm happy with them but i don't lust after them.

Sound:
exceptional sound for the money--especially when you take the time to set the different adjustments to suite your room. i have had my bx5's for awhile and was pretty happy with them. today i just recieved the SBX8 sub-woofer and together the system pretty well blows me away. i have e-drums, bass (including 5-string), guitars--all running through POD XTLive, synthesizer so i've just been playing around with everything and it's like they are brand new instruments to me because the Sub allows these speakers to do what they were really built for. i used to have to turn the level down when playing bass because you could really rattle the speakers but with the SBX taking all of the abuse these things really shine. with sub-woofer i would rate the sound as an 8.5

Ease of Use:
plug them in, turn them on. of course to get the most out of them you should spend some time optimizing the eq functions on the back.

Support:
i've dealt with M-audio support for other products and would say that they are pretty average.

Overall:
i don't think i'll upgrade these until they break. if that happens i would consider M-Audio again--probably the 8".
