Tear Inducing Clarity
Take the best of hi-fi sound quality, combine that with studio reference monitor accuracy, and add the power to cover a dance floor or a small festival stage. The AT312-MK3 is a 3-way active co-axial point source: precise imaging, enormous output, and the kind of resolution that makes you reconsider every system you've ever run.
Three drivers. One direction.
The AT312-MK3 builds its 3-way system around a true co-axial point source. Two 12″ neodymium woofers handle the lows. A co-axial 12″ midrange and compression driver occupy the same axis: mid and high frequencies arrive from the same point in space. Phase interference is practically eliminated. What you hear is the recording.
All the Advantages
Reference-monitor accuracy at live-event volume. The AT312-MK3 covers 80° × 80° conically: consistent coverage at every seat. 4,000W across three amplifier channels keeps every driver in its sweet spot. Pair with any BASSBOSS sub and ControlBASS handles crossover alignment automatically.
4,000W across three dedicated channels.
All-new MK3 amplifiers deliver 4,000W Class D across three independent channels: 2,400W to the dual 12″ LF woofers, 800W to the 12″ midrange, 800W to the co-axial compression driver. Higher output voltages sharpen transient impact. Auto-sensing 100–240V universal supply and IP65-rated Neutrik powerCON True 1 TOP connections for any environment.
96 kHz DSP with 8 presets on the panel.
The MK3 DSP runs at 96 kHz sampling with 8 onboard pushbutton presets and storage for up to 100 presets loadable via LAN. Every preset delivers HPF, LPF, phase alignment, precision EQ, and multi-stage driver protection. ControlBASS software (macOS/Windows) gives live remote control and seamless integration with every other BASSBOSS cabinet in your system.
Reference build for real-world use.
CNC-machined 18mm Baltic Birch plywood with dado joinery and extensive internal bracing. Four M10 fly points and six integrated handles cover rigging and carry. A 35mm steel pole socket gives ground-support options. High-pressure bonded polyurea finish is rugged, waterproof, and textured black. Perforated powder-coated steel grille. This is a workhorse: built for the road.
Take the stage.

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.
