Crescendo Audio HDL-1 Supertweeter

Description Crescendo HDL-1 Supertweeter The new HD series Supertweeters replace our legendary FT1 tweeter. Both the HD-1 and HDL-1 utilize a new magnesium alloy coated titanium diaphragm that surpasses the musical performance of the FT1. Each HD series tweeter features an optimized neodymium motor coupled to a CNC-lathed heatsink housing for improved thermal efficiency. Designed for smooth, controlled dispersion with extended high frequency range to gift the listener that high definition & hi-fidelity treble response that cuts through the mix. The HD-1 & HDL-1 are engineered to produce the same HD series sound signature but are sized for whatever your application calls for.

I've paired them with some pwx 8s and it sounds very good and gets loud. Nice push terminals as well made setting them up that much easier. Would definitely recommend
