Ruth's sister 44.4mm Treble Voice Coil Reel Tweeter Accs

SKU CH-2R4W-G9SVW

A 44.4mm titanium voice coil reel rated for 50W tweeter repair or builds

  • 4 mm coil diameter enables precise high-frequency response
  • 50 W power handling supports dynamic treble output
  • 8 Ω impedance matches standard amplifier outputs
  • Titanium-reinforced ABS skeleton ensures lightweight rigidity
  • 90 mm column centre distance suits professional tweeter designs

Voice Coil Reel for Tweeter Repair

This Ruth's sister voice coil reel is a speaker unit accessory built with ABS and titanium materials. It features a 44.4mm coil diameter, 8 impedance, and 50W power handling for treble driver applications. The component uses imported film designed to deliver greater sound pressure than resin alternatives.

Technicians Rebuilding Dome Tweeters

The part suits audio technicians and DIY speaker builders who are re-coning or repairing compatible dome tweeter units. Buyers needing a complete assembled driver with diaphragm and housing should look at finished speaker units instead of this standalone voice coil assembly.

44.4mm Coil Diameter Determines Fit

The 44.4mm coil diameter is the critical specification that decides whether this reel matches the target tweeter motor structure. Column center distance of 90mm, skeleton outer diameter of 66mm, aluminum ring diameter of 70mm, and dome height of 8.5mm must also align with the original design.

Highlights

  • 4 mm coil diameter enables precise high-frequency response
  • 50 W power handling supports dynamic treble output
  • 8 Ω impedance matches standard amplifier outputs
  • Titanium-reinforced ABS skeleton ensures lightweight rigidity
  • 90 mm column centre distance suits professional tweeter designs

Questions about this item

Does the 44.4mm coil diameter match my existing tweeter frame?

The coil diameter is 44.4mm and the outer skeleton diameter is 66mm; verify these against your current tweeter's specifications before fitting.

Will the 8-ohm impedance and 50W power rating work with my older crossover network?

This unit presents an 8-ohm load and handles 50W; ensure your crossover is designed for the same impedance and power range to avoid mismatch.

How can I confirm the voice coil is seated correctly after installation?

Measure the coil's DC resistance — it should read close to 8 ohms — then play a high-frequency test tone and listen for clean, undistorted output.
