Magic Compression Horns

The Diamond Audio M075T is a dual-stage horn design that has a much smoother sound. The full format diaphragm is large and robust and allows for extreme level output volumes. The magnet is in front of the diaphragm and the voice coil is on the front side of the diaphragm which allows for a much more compact horn design that easily fits in front of the midrange.

Bold Pro Audio Mid Woofers

The Diamond Audio MSPRO65 6.5" woofers have a better bottom-end response. The convex cone geometry increases cone rigidity under load while keeping the moving mass down. Installation Note: The factory speaker pods in the fairing require a light modification for magnet clearance. Simply heat the plastic speaker pod with a heat gun around the area where the magnet touches and screw the speaker in place. The plastic will then conform to shape allowing the speaker to fit perfectly.

Steel Speaker Grills with Horns Mounted

We stamp and mount the M075T horns for you. Black coated stainless steel fasteners are used and a CNC machined HDPE backplate so that the speaker grills match the integrity of the rest of the bike.

12db Crossovers Add a Lot to Performance and Reliability

The crossovers included in this kit though are 12db crossovers with a much higher power handling and more stable output at all volume levels.
