      Dual Voice Coil 5x7 Inch Fullrange Speaker - 15 Ohm & 4 Ohm

      Description
      This 5 x 7" fullrange speaker features a dual voice coil design equipped with both a 15 Ohm primary coil and a 4 Ohm secondary coil. Engineered for applications where a higher load impedance (15 to 16 Ohm) is required, this driver is ideal for vintage automotive radios, classic vehicle restorations, valve gear, and custom dual-source audio setups. Featuring a durable black cloth dust cover, it delivers clean, clear mono audio reproduction across fullrange frequencies.

      Technical Specifications:

      • Driver Size: 5 x 7" (127 x 178 mm approx.)
      • Speaker Type: Fullrange Mono Driver with Dual Voice Coils
      • Primary Voice Coil Impedance: 15 Ohm
      • Secondary Voice Coil Impedance: 4 Ohm
      • Power Rating: 15 W
      • Dust Cover: Black cloth
      • Mounting Hole Pattern: 110 x 110 mm
      • Baffle Cut-out: 118 x 170 mm (approx.)
      • Mounting Depth: 50 mm (approx.)
      • Total Height / Depth: 57 mm (approx.)
      • Overall Length: 183 mm (approx.)
      • Overall Width: 129 mm (inner frame) / 126 mm (across mounting tabs)
      • Supplied As: Single unit (1 speaker)

      Suggested Uses & Applications:

      • Classic Car Audio Restorations: Replacing original dashboard or rear-shelf speakers in vintage Australian, European, British, or American vehicles equipped with factory 15 Ohm or 16 Ohm mono radios.
      • Dual-Source Vehicle Setup: Utilising a single dashboard speaker location to connect two separate systems - such as running the original factory vintage radio on the 15 Ohm coil and an auxiliary modern receiver or hands-free kit on the 4 Ohm coil.
      • Vintage Valve & Tube Radios: Retrofitting older tabletop radios or console units requiring a 15 Ohm load matching output.
      • Commercial & Communications Gear: Industrial intercoms, PA systems, or receiver units specified for 15 Ohm driver loads.

      Installation & Wiring Warnings (What to be Careful Of):

      • Do NOT Connect Both Coils Together: Never bridge, wire in parallel, or wire in series the 15 Ohm and 4 Ohm voice coils into the same amplifier output channel. Because the coils have different impedance ratings and winding properties, combining them on a single amplifier channel will cause uneven load distribution, acoustic distortion, and potential amplifier overheating.
      • Verify Radio Impedance Match: Always confirm the required output impedance of your radio or receiver before connecting. Connecting a 4 Ohm load to a vintage radio designed strictly for 15 Ohm or 16 Ohm speakers can overload and damage the radio output stage.
      • Dual Source Isolation: If connecting two independent audio receivers to the separate voice coils, ensure both systems are not driven simultaneously at high volumes to avoid inductive feedback between coils.
      • Physical Fitment & Clearance: Measure mounting depth (50 mm) and cut-out size (118 x 170 mm) in your vehicle dashboard or enclosure prior to installation to ensure adequate terminal and magnet clearance.
