This is a custom bundle of four brand new PRV Audio D280Ti-S professional compression drivers.

They have a 1-inch exit throat and a titanium diaphragm, so they're built for clear, powerful sound.

The frequency response is 1,300 to 20,000 Hz at -10dB.

They handle 80 watts nominal, 160 watts RMS continuous program power, and peak at 320 watts each, so combined you're looking at some serious output.

Impedance is 8 ohms.

The voice coil is 1.75 inches with CCAW wire on a Kapton former, and the magnet is ferrite.

They're made by PRV Audio, MPN D280TIS, with UPC 0799928733854.

Just a heads-up: there's a California Prop 65 warning, but that's standard for many electronic components.

If you're building or upgrading a speaker system, these drivers are a beast.
