Features
Mounting: The tweeter is designed to be flush mounted from the bottom, with the mounting surface sandwiched between the included backing nut and threaded mounting flange. The threaded shaft is approximately 1⅛" tall, so the tweeter can be positioned within a range of depth/mounting height combinations.

- Required Cutout Diameter: 1.71" (compatible with 1¾" hole saw bit)
- Mounting Depth: 1.9" (minimum) -2.375" (maximum)
- Frame Diameter: 2.3"
- Mounting Flange:

- Height: 0.2"
- Backing Nut:
- Diameter: 2.25"
- Height: 0.2"
Terminals: The tweeter has spring post wire terminals and will accommodate up to 16-gauge wire.
Crossover: The included 3.3 μF capacitor is a 1st order high-pass crossover (6 dB/octave slope) and must be used if no other crossover is added; the crossover point is approximately 12 kHz. The capacitor is wired in-line with the positive input of the tweeter. The capacitor measures ⅜" diameter x ¾" long. When used, the capacitor should be soldered into speaker wire and insulated with heat shrink.
