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.

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!
