Haut-parleur 38cm Precision Devices PD.158
[PD.158-8] Avis/Critiques Perfectly suited for 1x15” or 2x15” horn loaded/bandpass sub bass designs, the smooth mid range makes it easy to integrate with the PD.C2 or PD.C14 compression drivers.
This transducer delivers commanding and powerful lows in compact cabinet designs.
DISPONIBLE EN VERSION 4 et 16 OHM sur commande et par 2 pièces uniquement.
• Heavy duty 15” 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
• B/L in excess of 27 T/m for fast accurate lows
• 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 of life on the road
