Description

Supplier availability is subject to confirmation; contact us before arranging collection.

The HELIX CI7 T20FM-SC is supplied as a pair of component drivers, not a complete amplified audio system.

  • 20 mm silk-dome tweeters with damped coupling volume
  • 4-ohm impedance; 1.5–30 kHz published driver response
  • Flush mounts, angled pods and extension cables included
  • Passive crossovers not included

Appropriate amplification and crossover/DSP filtering are required. Published frequency response is not a safe crossover recommendation. Tweeters must never be connected to an unfiltered full-range output; use the manufacturer’s specified high-pass protection. For 3-ohm drivers, confirm amplifier compatibility.

Compatibility, installation and delivery

Contact for install price. Supply only. FlexMount and WireKit vehicle-specific adapters are separate unless expressly listed above. Exact vehicle, mounting space, wiring and system compatibility must be checked before ordering; no universal BMW, Mercedes or other direct-fit claim is made. Fabrication, wiring, amplification, tuning and installation are quoted separately.

Prices include VAT. Delivery charges apply to shipped physical products at checkout. Workshop collection requires confirmed stock and an appointment.

UK price: £349.99 including VAT (£291.66 excluding VAT).
