The PAW 30 ND combines a paper cone, die-cast basket and 75 mm voice coil with a neodymium magnet. Its 400 W rated power and published Thiele–Small parameters support enclosure and crossover design. Bass extension depends on the finished cabinet; the free-air resonance is not a guaranteed lower operating frequency.
Typical applications
- PA loudspeaker cabinet construction
- Replacement driver work where the enclosure and crossover match the current specification

Installation and cabinet guidance
Check the 286 mm baffle cutout, fixing pattern and rear clearance against the exact drawing. Use a rigid baffle and fixings suitable for the 3.0 kg driver, tightening evenly around the gasket.
Connect the spring terminals to a suitable 8 Ω amplifier/crossover path, observing polarity. Keep the rear vent and cone movement clear of stuffing, bracing and wiring.
Choose the enclosure, port tuning and electrical filtering as one system. The manufacturer cabinet examples are starting points; allow for the volume occupied by the driver, ports and bracing.
Use the current 2025 drawing and parameters when replacing an older PAW 30 ND. Confirm the frame clearance and cabinet alignment before treating it as a direct replacement.
