Features

Power: The power handling specification (100 watts peak/50 watts RMS) is given when using a high-pass crossover, 4.5 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. For best results, solder speaker wire terminated with quick slides (item number 120FQS10PK, sold separately) to both ends of the capacitor, then insulate the assembly. Optimally, an electronic crossover should be used, and the capacitor discarded.

Mounting: Unlike most tweeters, the ST 44s have a wide flange and are top mounted like typical midrange drivers. They are also quite heavy, 3.4 pounds each, so the panel they are mounted to may have to be reinforced.

Measurements:

  • Required Cutout Diameter: 3.75"
  • Mounting Depth: 2.57"
  • Mounting Height: 0.42"
  • Flange Width: 3.98" (4.53" measured diagonally)
