Exceptional efficiency, power handling and frequency coverage from compact dimensions. Primarily for full range sound reinforcement and because of extended frequency response is also suited to multi-unit PA systems. Performance is optimised for full range singular / multiple use.
Please enquire about alternative impedances.
A.E.S. power handling test. Pink noise bandpass filtered at 12 dB per octave with cutoff frequencies of 50 Hz and 500 Hz. Driver mounted in free air, test signal applied at rated power for two hours.
Please note that the frequency response measurements are supplied for comparison only and are not a measure of the low frequency performance which may be achieved in a fully optimised system.
90.5 dB Sensitivity (1W/1m).
Exceptional efficiency, power handling and extended frequency response.
Kevlar cone for increased strength and rigidity.
Ideal for compact two-way and multi-way systems.
Works well in line array and studio monitor enclosure designs.
1-inch Polyamid-imide coated, copper voice coil.
