Precision Devices PD.188 PD188 600W 18" Driver 8 ohm
Designed to provide superlative performance when used in either a horn-loaded or reflex enclosure where fast accurate lows are demanded. 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 to produce direct radiating/horn loaded systems where the double suspension system allows it to thrive in the demanding touring sector.
- Heavy duty 18" cast aluminium frame with extra wide flange for increased rigidity
