The DJs are loving the low end. The DiaMons have massive headroom. Had such great feedback... everyone is happy with it.

Okay the BASSBOSS subs have always been impressive, but just heard the two DiaMon DJ112 Monitors during my set at Treehouse Miami and I’m completely blown away!!

When only the absolute best sound with no compromise will do in your nightclub bassboss products are the Lambo of PA speakers and subs. Every single component in the construction of the product down to the amplifiers they use are all the best possible parts available. If you are serious about your sound, BASSBOSS.

Ricky Lee
We recently had a friend—someone who’s played some of the biggest stages out there—perform on our BASSBOSS stage. After her set, she asked, “Who makes that monitor? That’s the best monitor I’ve ever used.” It was a Diamon!

See how the DiaMon-MK3 compares to the rest of the BASSBOSS mid-high product line.
Head to head
Click any sub to see how many of them a single DiaMon-MK3 can keep up with. Numbers are conservative; in practice the top usually has more headroom.
The DiaMon-MK3 in complete systems: subs and tops, dialed in and ready to go.

A compact 18″ sub that matches the DiaMon's small footprint while adding serious punch and extension on the dance floor.

The VS21-MK3 provides the deep low end the DiaMon was designed to be paired with. Together they produce a full-spectrum sound field from the smallest possible footprint.

Two 18″ drivers of controlled low end beneath the DiaMon: scaled-up impact for dance floors and outdoor stages.
Design your ideal system with our self-serve tools.
