I purchased two of these for on stage monitors, to accompany my Mackie SRM450v2's which are used for FOH. I work in a duo, so backing tracks, live keyboard, and microphones.
They have plenty of power for personal monitoring. Sometimes when my FOH speakers are a bit further away from me I miss a bit of bass oomph in the monitors, but then you're not going to get that from 8" speakers. However, clarity is very good, and portability is fantastic. The handles keep coming loose, and every 2-3 months I'm taking of the front grill, taking the driver out, and re-fitting the handle. It's just a little nut and bolt so it's not a big deal. Never had any faults with them, even though they've been bumped around in my boot, and fallen out of my car. Brill product!
