Feature:
A small amount of adjustments on the back. Not many variations, but good enough for me, they sound best flat anyway.

Quality:
I've used Alesis products for a while and have never had any issues.

Value:
You can't beat the price performance when compared to other powered monitors.

Sound:
I upgraded from unpowered Alesis Monitor One MKIIs. The sounds characteristics are remarkably similar. I'd have to say that the highs are smoother though, much less ear fatique. The bass also seems more controlled and less muddy. The imaging is very good with low distortion at all noise levels I've tried. I have a small project studio so they get loud enough for me. The bass is ok but there is only so much a 6 1/4 woofer can do. The frequencies do roll off fairly smoothly when they do get too low. One complaint, if you stick your head near the tweeters when the power is on but with gain all the way down, you can hear a faint hiss. I don't know if all powered monitors do this, but it's fairly annoying considering I have a very quiet room.

Ease of Use:
If you understand what powered monitors are, this is easy.

Support:
Never dealt with them

Overall:
I'm still within the return period and may look around at other monitors to see if they have that hiss at no volume problem. Not many fall within this price range. I may look at KRK.

Feature:
Missing standard chinch connectors

Quality:
It seems this product is intended to fail after warranty. There is a design fault on the circuitry board that has been known for years and appears also on the 520, Mk2 and other speakers from Alesis: Some parts are soldered too close together, they will burn out after more or less time, thats for sure. There are many complaints all over the web. Mine failed after 18 months. Service repair would probably just change the board and a year later I would have the same again. A friend changed the parts and solved the design problem. The parts are just 10$.

Value:
Taking in account the problems with the board, I would not even take this speakers for a price under 300$

Desirability:
It looks good and plays well. But only for a year.

Sound:
The sound has good resolution. But there is a strong groundnoise or hiss, good hearable up to 2 meters distance.

Ease of Use:
I very like the buttons on top of the speakers. They are really easy to reach.

Support:
Thea have sent me their local service center address. But Service repair would probably just change the board and a year later I would have the same problem again.

Overall:
If it fails again, I will replace it, sure will never buy Alesis again!

Feature:
features are dope u could change ur lows,mids,and highs.. in addition u could increase or decrease the gain

Quality:
once again the quality is amazing. mixes sound perfect and scratching on these speakers is clean!!!!way better quality than the rp 8's and m-audio bx 8's...however the base is a little too tite. the m-audio bx8's seem to have much more bass

Value:
400$ shiets a better monitor and better price than alot of other speaker monitors out there

Desirability:
these speakers are straight up sexy nice and slim and not as bulky as the krks rp series or the m audio bx series.. these speakers pack a punch!

Sound:
damn! these speakers are amazing! best quality speaker monitor! it destroys the krk rp8's and the m-audio bx8's in sound quality and price!!

Ease of Use:
too easy to use all ya need is some XLR'S OR QUARTER INCHES AND UR STRAIGHT!

Support:
N/a

Overall:
Overall these speakers are perfect for wat i do. in the near future im probably goin to purchase a sub for these speakers so i could use the full potential of these speakers..
