SPEAKER-X in Space Ship Gray


SPEAKER-X with tone-wood resonating back panel and internal resonator and twin by-pass ports


SPEAKER-X Is a 3-way, 5 driver, true bass-horn loudspeaker with unique hybrid horn loading. All six drivers utilize the horn with the correct timing: dual side mounted bass-drivers vent through the mouth of the horn as do the dual wide-band drivers which are slot loaded half way inside the extra large horn. The dual neo ribbon drivers are mounted in the mouth of the horn with a substantial set-back which helps with timing. In summary all six drivers fully utilize the extra large horn for a seamless overlapping soundscape with pinpoint imaging, exceptional detail, and thunderous bass.
