Power	Diameter	Impedence
300 watts	10" - 25.4 cms	8 or 16 ohms

	Heavy duty 10" cast aluminium frame with extra wide flange for increased rigidity

	300WRMS

	2.5" copper voice coil assembly

	90 oz. ceramic magnet

	A B/L in excess of 24 T/m for dynamic voicing

Description:

Designed primarily as a high power, mid frequency transducer, the large magnet structure gives excellent control and thermal properties. An ideal choice when supporting our 15", 18", 21" and 24" bass drivers in high power systems that require additional power handling than offered by the PD.102ER. It is equally well suited to direct radiating and compression (horn) loaded designs. Also suitable for vocal performances as the PD.107 covers the critical vocal range in a single, highly effective unit.
