Customers compare this with the PD1550

This 15″ Full range loudspeaker is fitted in many BishopSound speakers but is frequently used as a punchy woofer in DIY speaker cabinets or as a replacement driver for B&C or 18 Sound where replacement Nexo, JBL, EAW, Void, RCF, D&B, KV2, Peavey, Martin, Meyer Sound drivers are too expensive.

This 15" Full-range loudspeaker is ideal for use in vocal PA, keyboards, club systems, and earth-shaking subwoofers.
