I'll try; it's been a couple of years, so I'll do my best to remember. First off, both Accugrooves were really tight and accurate sounding. There wasn't much 'bleed' out the sides or back of the cabs, unlike my EV B-410, which is loud in every direction. Unlike my EV, the Accugrooves were deep sounding without being boomy. Now, I cut my teeth on SVT's way back when, so there's just no single 12 cabinet that really does it for me, which probably has a lot to do with why I didn't like the Tri-12's as much as the El Whappo Jr. I even tried the set of Tri-12's against the Jr, and to my ears, the Jr just had more life to it. Deeper lows, livelier highs, that sort of thing. Anyway, after deciding which one I liked best, I took the Jr. on a few gigs, and it was excellent. I've always had difficulties with boominess, but not with the Jr. I can only imagine what an El Whappo would be like! Anyway, I was definitely going to get a Jr, but life intervened (divorce, child support, etc.), and I'm still stuck with my old EV for now, which isn't exactly slumming, but when you know something better is out there, it is kind of annoying.
