So, I own an Accu Groove Tri112. I'm impressed with the thing time & time again. I did a gig with one of the bands I play in. We were opening for a "bigger" headliner. They had their gear set up on stage.....the headlining band didn't really give me a definate yes or no on whether or not I could use their bass rig. It was an Ampeg 6x10 with the big 'ol SVT Tube head. Quite large. Just to play it safe, I brought in my little rig & set it up infront of the refridgerator of a bass rig. I'm currently powering my cab with the Peavey Tour 700 bass head. I plugged in & turned up/ plunked a few notes. The bassist from the headlining band quickely ran in & started yelling at me..."Hey man! What are you doing!? You're gonna blow my speakers! Turn my rig down!!" As he got close enough to see what was going on, he got this confused look on his face. He couldn't believe how much sound was coming out of such a small rig. He was convinced that I had chained both of our bass rigs together/ or I was running through the PA.....nope. He turned around & walked away. It's like it hurt his feelings. Not to knock Ampeg/ or any bass rig that's on the large side; These Accu Groove cabs can really dish it out. I thought that I would need to purchase a couple of 2x10's or a 4x10 of some other brand....then I heard these. 1 of the TRI112's is about equal to just about any 2x12 or even a 4x10 out there (as far as volume). On top of its volume capabilities, the sound is so clear. There's no gaps. Nothing is hyped. It puts out what you put in. Two of them together are sick! & that's just the TRI112....The TRI115/ TRI210/ El Whappo....super duper cabs. The people at Accu Groove are even better than the cabs!
