Completed my pair of Omni 15s this morning, and was MOST impressed when I fired them up with my EA iAmp 800 and my G&L L2000! These cabs seem to be a great match for the very neutral iAmp, as I was able tle leave the eq completely flat and it sounded perfect (which is the same way I run my EA cabs whenever possible). Way more volume than I'll ever need, but if I have to share a stage with another caveman/basher drummer or some guitarist that believes he can't get "his tone" without a full Marshall or Mesa stack...I'm ready! What's also really nice is the angle of the upper cab's woofer...it's nicely angled to ear-level, so you get good coverage both up close and at a few feet.
Hooked these guys up to my PA rig afterwards and again, they sound great driven by my Mackie 1604VLZ mixer and 1400i power amp. I am struck at how musical the tweeters and mid drivers are in these cabs. Very smooth, and very natural-sounding (to these damaged old ears, anyway). I added the L-pads and pole-mount top hats so I can use them as PA or bass rig, so I have a pair of really versatile cabs....looking forward to using them on a gig! Will post further comments when I have them.
