F 17 PWH

The F 17 PWH is concepted as a straight waveguide horn with a vented transducer cabinet. The recommended active x-over frequency is 160 Hz, 18 dB/oct. Butterworth. The 18" EVX 180A OEM loudspeaker chassis is reliably protected against critical power levels and short thermal overload by thermo switches and 4-way halogen lamp protection. The F 17 PWH cabinet is made of poplar plywood 18 mm. All corner joints and braces are grooved and glued. Braces are screwed additionally in order to reduce natural resonances to a minimum. The cabinet surface is finished in extremely resistant needled black-mottled felt. A powder-coated steel grid and an acoustic foam front protects the speaker front. The connector panel uses two 4-pole Speakon connectors (Input/Output) for safe connection and easy chaining to the next loudspeaker. The 2 handle trays on the sides guarantee easy and safe transport. 4 large-sized rubber feet and 4 castors allow easy handling and safe stand. A recessed speaker-stand threaded flange on the top allows various setups (clusters, sidefill, top).
