Crescendo HDL-1 Supertweeter - 4Ω

The Crescendo HDL-1 is part of the new HD series, replacing the legendary FT1 tweeter with a magnesium alloy–coated titanium diaphragm that delivers smoother, more extended high frequencies. Featuring a neodymium motor and a CNC-lathed heatsink housing, the HDL-1 is built for thermal efficiency and precision, providing high-definition, hi-fidelity treble response that cuts through the mix without harshness. Sharing the same sound signature as the HD-1 but in a slightly larger format, the HDL-1 is ideal for applications that demand even higher output.
