Small circular metal diaphragm with voice coil 34.4mm diameter 7.2 ohm impedance

Ruth's sister

Ruth's sister 34.4mm Treble Voice Coil 7.2OHM internal power cable

SKU CH-9F1B-RPCFS

A 34.4 mm professional treble voice coil with 7.2 Ω impedance and imported film diaphragm for DIY tweeter builds

  • 4 mm coil diameter fits compact tweeter designs
  • 2 Ω impedance matches standard crossover networks
  • 34-core imported film delivers higher sound pressure than resin alternatives
  • 03 mm ultra-thin diaphragm reduces moving mass for faster transient response
  • 8 mm outer diaphragm diameter provides wide dispersion for treble clarity

Treble Voice Coil for DIY Speakers

The Ruth's sister treble voice coil is a 34.4 mm diaphragm assembly designed for professional tweeter builds. It uses imported film material that delivers higher sound pressure than resin alternatives. The coil impedance is 7.2 ohms, matching common crossover requirements. Supplied as a single unit for DIY speaker projects.

Suited for tweeter repair or custom builds

This coil fits builders who need a 34.4 mm diameter voice coil with a 50.8 mm outer diaphragm and 6.2 mm height. The aluminium ring measures 62 mm outside diameter and the diaphragm thickness is 0.03 mm. Buyers who require a different impedance, larger coil diameter or a complete driver with magnet assembly should look elsewhere.

Critical spec: 34.4 mm coil diameter

The coil diameter of 34.4 mm determines whether this voice coil matches your tweeter former and gap. Verify the dimension against your existing driver before purchase. The 7.2 ohm impedance and 50.8 mm diaphragm outer diameter are fixed by this specification.

Questions about this item

What limits the 34.4mm voice coil during sustained high-output use?

The 7.2 ohm impedance and thin 0.03mm diaphragm set the thermal and mechanical limits during extended operation.

How much heat or noise does the 34-core treble coil generate when running all day?

The lightweight metal construction and imported film diaphragm produce minimal self-noise; heat depends on amplifier power applied to the 7.2 ohm load.

What other parts must I already own to install this 34.4mm voice coil?

You need a compatible tweeter frame, diaphragm assembly, crossover network, and enclosure suited to the 50.8mm outer diameter and 62mm aluminum ring.
