PD 1850 18" ......800 Watts RMS

• Heavy duty 18” cast aluminium frame with extra wide flange for increased rigidity
• 800 Watts RMS
• 5” copper voice coil assembly
• 170 oz. ceramic magnet
• Power compression only 1.6 dB at rated power *1
• Distortion *2 2nd Harmonic <1% * 3rd Harmonic <1%
• Advanced magnetic assembly incorporating a composite alloy & steel pole piece giving a uniform and stable magnetic field, improving linear excursion and providing an efficient thermal path to dissipate the heat produced by the voice coil.
• A B/L in excess of 31.57 T/m for fast accurate lows
• Exemplary electro-acoustic performance & long term reliability in all types of professional applications
• Double suspension system maintaining a pure piston action for the moving mass even when driven with the most complex programme input signals and provides additional durability against the rigours

APPLICATION NOTES
Designed specifically to provide powerful and accurate bass frequencies with minimal distortion and power compression. The PD.1850 is the superlative choice for top of the range sub bass systems where the ability to take punishment in the most demanding applications is the ultimate selection criterion.

Suitable for sound reinforcement in a variety of enclosure types since it allows enclosure designers considerably more freedom with specialised loading techniques without having to make allowances for physical characteristics or power handling limitations which are typically the result of more traditional designs.

Appropriate for applications as diverse as scoop bins, conventional reflex cabinets and horn loaded systems.

*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 PD.1850 may significantly exceed that of other manufacturers with high published power ratings.
*2 Distortion is measured at 10% of the rated power (AES Standard)
