*1 Power compression is the reduction of sensitivity at the specified power. Higher power
ratings do not necessarily give a proportionate increase in SPL therefore the maximum SPL of
the driver may significantly exceed that of other manufacturers with high power ratings.
** Distortion is measured at 10% of the rated power (AES Standard).
1. AES Standard (30 to 300 Hz) @ 1000 Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 1000 Watt preconditioning period.
Please note that frequency response measurements are supplied for comparison purposes
only and are not a measure of the low frequency performance which may be achievable in a
fully optimised system.
*2.83V. Half space response measured in a 975 Litre sealed enclosure.
• Vented cast aluminium chassis for improved thermal control of voice coil.
• Vented motor structure for improved control of power compression.
• 50 mm peak to peak travel.
• 31 T/m BL.
•
Dual suspension assembly.
• Inside/ outside voice coil windings.
The PD.185C003 is ideally suited to applications where high power handling,
long excursion and perfect linearity is required. Ideal for bass reflex and horn
loaded enclosure systems where a high punch and low sub is required. The robust
mechanical design and construction makes this unit an ideal choice for high power
high SPL bass applications.
