The PD.185C001 is ideally suited to applications where high power handling, long excursion and perfect linearity is required. Completely versatile in bass reflex and horn loaded cabinets. TSP’s naturally suit all PD.186 applications but offer increased horsepower and punch.

Conceived around the famed PD.186. The PD.185C001 engineering has been focussed around minimal weight using a traditional ferrite magnet motor system. Weighing in only 13Kg, it's lighter than some neodymium models available on the market today! The robust mechanical design and construction makes this unit an ideal choice for fixed or touring applications.

Notes
* 2.83V. Half space response measured in a 950 litre sealed enclosure.

*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) Program 900 Watts.

2. AES Recommended Practice.

3. Thiele - Small Parameters follow a 900 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.
