Serve Simply Smashing Sophistication Sound with the BASSBOSS DiaMon-MK3 12-Inch Coaxial Powered Top Loudspeaker

The secret of the DiaMon-MK3 is its size. It's tiny but it's fierce. It's often misunderstood, so the DiaMon-MK3 may be perfect for you and you would never know it. Do you always take subs to your gigs? Good for you! A philosophy we can get behind 100%! But if you have subs at every gig, do you really need a full-range top cabinet?

Picture a 12-inch 2-way top cabinet. How big is it? It's almost impossible to fit a 12-inch woofer into a cabinet that's less than 14 inches wide, and then you have to add a horn for the highs. You've seen them, lots of them… Let's look at the concept of a 12-inch 2-way a little differently.

A 12-inch woofer can get pretty loud. If you need it to produce bass, the cabinet will need to be big and the voice coil will probably need to be quite big and the amp will need to have lots of power… But what if you were going to use this 12-inch woofer for mid-bass and midrange only? The cabinet could be pretty small, and a small cabinet is a light cabinet. The voice coil could be smaller and the cone could be lighter, making the woofer more efficient. Making the coil smaller means you can make the magnet smaller, which also makes the cabinet lighter. With a more efficient woofer, you don't need such a big amplifier, which can also save weight and cost.
