Description
Special order. Supplier order required; confirm availability and lead time before ordering. Not represented as local shelf stock.
The HELIX Ci5 T25FM-CA is supplied as a pair of component drivers, not a complete amplified audio system.
- 25 mm ceramic-coated aluminium domes
- 4-ohm impedance; 2–25 kHz published driver response
- Flush-mount fittings and angled mounting pods 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.
