Product Research

Features

Power: The power handling specification (100 watts peak/50 watts RMS) is given when using a high-pass crossover, 5 kHz and 12 dB/octave.

Crossover: The included 3.3 microfarad capacitors are 1st order high pass crossovers (6 dB/octave); the crossover point is approximately 12 kHz. One capacitor is wired in-line with the positive input of each tweeter. Optimally, an electronic crossover should be used, and the capacitor discarded.

Mounting: The ST 25 tweeters are designed to be flush mounted, with the mounting surface sandwiched between the included threaded mounting collar and threaded trim ring. The threaded shaft is approximately ⅞" tall, so the tweeter can be positioned within a range of depth/mounting height combinations. An optional threaded flange is available (301AFR25, sold separately) to top mount the tweeters.

Measurements:

  • Required Cutout Diameter: 1.708"
  • Mounting Depth: 2.17"
  • Trim Ring:
    • Diameter: 2.252"
    • Height: 0.19"
  • Mounting Collar:
    • Diameter: 2.252"
    • Height: 0.19"

Terminals: The screw post terminals will accept bare wire up to 12 gauge.
