I'm ordering these speakers to check them out.  I definitely like the usb feature.  It will be interesting to see how the internal sound card sounds and will report on that.  I like the fact also I can use the usb to hook up to my laptop instead of running audio cables.  The front volume knob is nice also.

I've always liked Alesis after doing comparison shopping at Mars music... (remember them?)   I liked Tannoy but the bass used to get lost in the mix.   Also my friend with Tannoy's seemed to be replacing tweeters a lot.  With the Alsesis Mk1 and the big brothers I could always hear the bass.   Maybe since I'm a bass player I was looking for a particular sound.

These M1 Active 520 is the third generation of the Alesis M1 Active Series. The 520's offers nice bass and mid-range presence and flat frequency response from its high-precision driver and sweet spot crossover. With a redesigned driver, bass density control and EQ, this  high-precision active reference monitor delivers!

UPDATE:

I've had these for over a year, using them every day, so I thought I would do an update.  I must say they sound good.  No problems at all.  I still haven't gotten around to using the interface to the computer yet.  I guess I'm a midi guy too much going in to the computer.

They are a fine replacement for the Studio One if space is an issue or you don't have a power amp to drive your mk1 or whatever you are using.  About the only down side to these speakers if they are doing double duty as computer speakers for the net and mixes, they are fantastic for mixing.  But I must say there are times I wish they had a tone knob front side.
Every once in awhile I'l visit a website that the audio is just too bassy and it would be nice to turn the treble up without going in to the computer.

But this wouldn't keep me from buying another pair.  They are holding up nicely.  and the crossover point is excellent considering all the trade-offs.   Every once in awhile I see someone complaining of no bass response.  Mine has plenty but not too much.  You're not going to rattle the windows in your house with these little 5" speakers.   I guess you could but I wouldn't push it that hard, I can definitely hear a good bass tone and that is why I always go Alesis for playbacks.

UPDATE 2: I used the interface and I must say it works good. Good fidelity, I can't compare it technically to other upscale brands because I don't know the specs off hand. But it worked good, clean. What I like about it, the computer I was using it on wasn't my main music computer. I wanted to lay down a bass line so I used the USB connection, went in to Reaper, laid the track and it worked great. So yes, the interface works well and the speakers still get comments when people are listening to my recordings.
