  • Option wood cover available for certain driver models. The cover replaces the rear cover on the compression driver to increase the rear chamber volume.  This effectively flattens the phase response near the horn’s low frequency cutoff.  The rear chamber is then packed with alpaca wool to reduce subtle resonances in the upper treble.
