Hi,
I own a set of 152's that I use for monitors. I believe they are identical exept for design and the mid. First let me start off with the good news about them. They are rediculously durable. I work with nothing but punk bands and drunkards, so my monitors have been dropped, kicked, beered, and a truck ramp was dropped on one once. So far the accumulated damage is one small scrape and one very slightly dented grill. I also use them for my own band where I sing. And I have never heard myself better. Even with the hypercardioid condenser mics I use, I can place one monitor in front of me (which you shouldn't do with those mics) and I can still hear myself very accurately above my rediculously loud band (if you are familiar with The Boyzz, I currently play with, Mike, the guitarist LOUD!!!!). Vocals and guitars sound great through them, snare and toms sound pretty good. They start to have a problem with the lower frequencies. They project the "pop" of the kick drum pretty well, but the guts aren't there as much as I would like. But, then again I might just be to picky. After all they are designed to be monitors and they were $329.
For what it is worth, I got comments from some of my clients after their band performed with the set of four and I could not even solicit a bad comment. These acts ranged from heavey metal bands to adult contemporary lounge acts, to blues bands and aside from the occasional request for an alteration in the mix there were NO BAD COMMENTS!
For monitors, I believe they beat out mpro's and sr-x's. Unequalized, running my own sound from stage, I've gotten these to sound better than sr4722x's run by a dedicated monitor mixer at a big gig. By the by, I run them passive and the 4722's were run biamp for those curious. They are beaten in clarity and volume by community sls920's though.
So basically
a run down of qualitative specs
Durable--Hell yeah
Loud--yep
clear--enough
bassy--leaves some to the immagination
For the price they are unbeatable!!! But I'm still debating about using them as an foh system.
SEACREST--OUT
