WH3 Single 21″ Low Frequency Horn

Category:

Description

The WH-3 is a full-size 13 foot long folded low frequency bass horn with a 32 Hz flare rate. At the heart of the horn is a 21 inch low frequency transducer with a 6” voice coil, 2000 Watts RMS, 4000 W Program and 8000 W peak power rating. It has the acoustic output of two of our WH1 18” folded horns. The expansion of the horn is constantly curved with no abrupt angles to color the sound. All the unused portions of the box are filled with hard polyurethane foam to increase efficiency and damp internal resonations. The result is clean, clear, well-defined, high-output low frequency reproduction.
