Haut-parleur 46cm Precision Devices PD.188
[PD.188-8] Avis/Critiques Designed to provide superlative performance when used in either a horn-loaded or reflex enclosure where fast accurate lows are demanded.
Delivers faultless low end performance in applications in which others fall by the wayside. Perfectly at home in new or refurbished horn loaded sub bass systems this unit also delivers powerful lows in reflex designs.
An exemplary choice for upgrade or replacement situations where the capability of the PD.188 to “drop in” and provide outstanding bass response makes this a versatile, popular and highly effective unit.
Well suited to use with PD.107/PD.121 and PD.C2/PD.C14 in direct radiating/horn loaded systems where the double suspension system allows it to thrive in the demanding touring sector.
DISPONIBLE EN VERSION 4 et 16 OHM sur commande et par 2 pièces uniquement.
• Heavy duty 18” cast aluminium frame with extra wide flange for increased rigidity
• Sub Woofer
• Field replaceable magnet for touring applications
• 600WRMS
• 4” copper voice coil assembly
• 125 oz. ceramic magnet
• A B/L in excess of 26 T/m for fast accurate lows
• Double suspension maintains pure piston action for the moving mass even when driven with the most complex programme input signals and provides additional durability against the rigours of life on the road
