Diamond Audio M1SRT Short Throat Horn Tweeter

The Diamond Audio M1SRT is a short-throat horn tweeter with the best sound quality of any horn Diamond builds — extreme pro-audio output and clean, detailed highs in a body short enough to fit where other horns won't. A great finishing touch on a bagger, a boat, a slingshot, or a car-audio front stage.

Why we recommend it

The M1SRT is the improved replacement for the acclaimed MSRPRO1 horn. Its refined phase plug (the bullet in the center) delivers standout sound quality with a big 106dB sensitivity across a 3kHz–20kHz range. It shares the same face diameter as many bullet-style horns on the market but has a much shorter body and shallower mounting depth, so it drops into tight spots where longer horns simply won't fit. The diaphragm is rebuildable for long service life.

Fitment & install notes

Shallow 1.12" mounting depth, 1.75" cutout, 2.28" overall. 4-ohm with an included 12dB crossover for protection. Pair with pro-audio mids for a complete, high-output front stage.
