Looking to do the modular thing with my new Aguilar TH500. I currently have a neo 4ohm 115 in an old ampeg cab, but i think it might be blown b/c it was distorting badly when the amp was starting to clip at my first gig with the new setup. Need to test it again today. Any rate, trying to decide on an 8ohm Avatar neo 210 or a set of Hartke hydrive 112's. The 210 would likely work for most of my gigs (bars, weddings), and for outdoors/larger rooms i could pair it with an old hartke 410 or with the ampeg cab if i replace the speaker with an 8ohm. I'm aware of the debate about mixed drivers, and that's part of the reason for considering abandoning my old cabs and going with the 112 pair. I like the idea of taking a single 30lb 112 to practice and smaller side gigs, but i think most of the time i would need to stack both...in which case am i really slimming my load in? If the sound profile is better in the end, that's all that matters, i suppose.
