OMG… I never thought there would be such efficient speaker systems available. What incredible sound! The kids love the bass because they can FEEL the music. BASSBOSS has made such a difference to our students at the Texas School for the Deaf.

We set up four of the 218s and 2 of the 312s and ran through every genre of music we could think of. Honestly, it was an emotional experience hearing music sound that clear and magical. I didn’t have to touch the EQ at all, it had crystal clear and flat frequency response. It just couldn’t have been more perfect.

I don’t have do anything to the system for it to sound incredible. For 1500 people just two people can load in and I can run it hard enough that I would think it would distort. I can’t make it distort! I can run it that hard and my amps barely get warm. So much easier to move! It cut down set up time from 2.5 hours to 20 minutes. My wife sets up the system for me. 💪🏼💁🏻

Just wanted to let you know that we received the speakers this past Friday and everyone is thrilled. The AT312s are amazing. We did an A/B comparison test outside against 6 QSC KLA 12″ line array cabs and the 312’s blew them away.
