Sweet and strong,
packs a wallop.
Ultra-deep, liquid BASS.
A rum punch of bass: sweet, deep, and powerful. Horn-loaded for the attack, vented for the extension, giving you total dance floor mastery.
You really can't have too many. 😉
A deep reserve of class-D continuous power means the amplifier is never the bottleneck. Higher rail voltages slam the peaks, while steady sustained output keeps the low end liquid.
The secret ingredient is powerful DSP limiting and protection.
Five limiters work in concert, including thermal, excursion, and clipping, each protecting the driver differently. The woofer can take everything you throw at it while the transients stay clean.
Warning: BASSBOSS is addictive.
The 6th-order bandpass hybrid has a large vented chamber tuned low, front-loaded onto a short horn that boosts sensitivity in the upper range. This combo creates a beautiful blend of impactful mid-bass and the low-lows down to 28 Hz.
Save your presets for max impact.
96 kHz DSP with 8 onboard presets, switchable in real time with zero dropout. Store up to 100 more with ControlBASS. Dial in once, save, rinse and repeat.
Parties anywhere, in any weather.
The auto-sensing 90–250VAC power supply provides reliable performance worldwide, and IP65 waterproof connectors with weather-sealed inputs keep the electronics safe from the elements.

They deserve every penny!! I've wanted the speakers to be loud but at the same time provide a flat and clean frequency response without distortion. BASSBOSS delivers exactly that.

Just had a killer show last night. We absolutely destroyed the club. The rig is sounding great! Here's what they said: "Kicked ass and props on the bass too, sound was really good!"
Eddie Mapp
FOH Touring Engineer
The human range of hearing starts at 20 Hz. Why settle for 40 Hz? BASSBOSS creates pure, powerful and natural low-end. When listening to acoustic tracks I heard and felt depth in the music that I haven't gotten from other speaker manufacturers.

Stage, Lights & Sound
I have been using Meyer Sound for years. I was at a festival and a friend of mine was running the BASSBOSS Subs. I was floored by the sound levels BASSBOSS was able to achieve using half the number of cabinets. From that point on, I switched to BASSBOSS.
