Listening impressions

This one sounded great right out of the box. Not too surprising, I suppose,
considering my previous experience with the TriTrix MTM. Not trusting my aging
ears, I enlisted Wayne Wendel for his impressions. He proclaimed the voicing
was just about perfect, with tight bass, sounding more like a larger sealed
design than a small vented one. While missing the final octave of bass, they are
quite adequate for most music genre. I specify an adjustable length port, but we
felt it sounds best without the slide on extension. While they model with roughly
3 dB less max SPL than the TriTrix MTM, a pair of these can certainly provide
adequate output for even larger rooms.
