Ruth's sister 72.2mm Titanium Treble Voice Coil Reel

SKU CH-PQ4N-726A4

A 72.2 mm titanium diaphragm voice coil reel for professional tweeter drivers with a 6 ohm impedance and 103 mm total diameter

  • Titanium diaphragm delivers clear treble with 91 mm diameter
  • CCAW voice coil on 72.2 mm KSV bobbin for low distortion
  • 6 ohm nominal impedance matches professional tweeter designs
  • Ultra-thin .05 mm film handles high sound pressure
  • Light 103 mm total diameter reel simplifies storage and handling

72.2 mm Treble Voice Coil Reel

This 72.2 mm titanium treble voice coil reel is built for compression-driver tweeters in home-theatre and professional audio systems. Its KSV bobbin and CCAW winding deliver clear, noise-free output with low power consumption. The imported film construction yields higher sound pressure than resin alternatives. It suits technicians and DIY builders who need a lightweight, ready-to-install diaphragm assembly.

91 mm Titanium Diaphragm Headroom

The 91 mm titanium diaphragm, 13.5 mm high and 0.05 mm thick, handles treble frequencies with high sound-pressure capability and minimal distortion. The 6 ohm nominal impedance matches standard crossover networks for smooth integration. It runs out of headroom when pushed beyond its thermal and mechanical limits in high-SPL professional reinforcement, where larger-format diaphragms are required.

103 mm Total Diameter Fit Constraint

At 103 mm total diameter the reel fits compression drivers designed for this frame size; it will not mount in drivers with smaller throat openings or different bolt patterns. The 72.2 mm (2.02 in) coil diameter fixes the magnetic-gap geometry, so the part cannot be adapted to voice-coil bores that deviate from this specification. Installers must verify driver compatibility before purchase.

Questions about this item

Will the 72.2 mm coil fit the compression driver I already use?

The coil diameter is 72.2 mm and the total diameter is 103 mm; compare those dimensions with your driver's voice-coil opening and mounting pattern before installing.

How can I verify the 6 ohm nominal impedance after installation?

Measure DC resistance across the CCAW winding with a multimeter; a reading near 6 ohm confirms the coil is intact and correctly seated.

Does the package include adhesive or a replacement diaphragm for the 91 mm titanium unit?

The box contains only the treble voice coil reel; adhesive, ferrules and any additional diaphragm must be sourced separately.
