I recieved these cabs "on loan" to use for an extended period of time. The details of how/who sent them for the moment are going to be kept quiet. Anyway, this is going to be brief, I'll update this post later after a gig or two are through them. The first thing I noticed is how much these two cabs sound alike. The 115 seems to just sound "bigger" than the 112, but in no way (IMO) extreamly different like most 115 vs. 112 can be. I will say this, in the past I have not been the biggest fan of AccuGroove. The cabs I played out of did not impress me a whole lot (2x8 and another one they don't make any more). Couple that with the issues surrounding the "switch" and they didn't fair too well. BTW, if any thing gets out of hand on this thread reguarding the switch or general bad mouthing of AccuGroove like I've seen in past threads, I'll ask for it to be deleated. Let's stay on the subject at hand OK!? BAck to the cabs.... They are not like other cabs. Not at all in how they sound. From what I can tell, there isn't any "EQ-ing" of the cab like others. To break them in, I played music through them for about 5 hours at a pretty good level (not really loud). The first thing I noticed was they sounded stinkin' great with audio through them. Something almost all bass cabs do not sound good doing. A pair of Tri-112's on poles would kill as a PA!! These cabs are made to be EQ'ed. What I mean is they will reproduce what you put in. At a rehersal with a country band (who normally plays at a pretty quiet level) I took just the Tri-112. This night they decided to play pretty damn loud. I noticed that I could hear myself better and I was at a lower level than what I would normally would be for this volume. The Tri-1112 performed fantastic. Lows were nice and tight without being "boomy". The mids were not harsh and the highs were actually a bit quiet, but smooth none-the-less This was an issue with a lot of guys reguarding the highs, but for me, they were fine. The amp/basses were my Acoustic Image Focus, Smith BSR5J-MW and old 70's Jazz with super old Barts- passive BTW. My old cabs were Epifani UL112's FWIW. I haven't tried my BSX Allegro 5 through them yet, but I will in the next day or two. I have two loud gigs next week- one outdoor with the country band and the next night with a loud funk/R&B band. I'll be taking both cabs to both gigs. I'll post up again after the gigs. But as of now, these things are pretty sweet. Very versitile. And not as "colored" as most other cabs on the market.
