Haut-parleur 30cm Precision Devices PD.122
[PD.122-8] Avis/Critiques Medium resonance 400WRMS bass driver with a smooth response down to 40Hz in a reflex enclosure, the PD.122 is an ideal selection when building/re-furbishing stage wedges.
Well suited for use in small compact full range systems in combination with our PD.C14 or PD.C2 compression driver.
An excellent choice for compact/portable systems where the powerful bass response eliminates the need for a dedicated subwoofer where circumstances do not allow for a separate 18”, 21” or 24” unit.
DISPONIBLE EN VERSION 4 et 16 OHM sur commande et par 2 pièces uniquement.
• Heavy duty 12” cast aluminium frame with extra wide flange for increased rigidity
