The aperiodic design utilizes a highly damped vent (not a bass reflex port) whose acoustical resistance is very precisely controlled. This lowers the “Q” of the system through a high friction venting action. The listening result of the aperiodic design is better control of the bass and improved transient response producing noticeably better defined bass with none of the typical “boom” that is quite common to ported speakers.
Cabinet resonances are known to be a significant cause of coloration in speaker systems. Extensive bracing of a typical MDF enclosure can help reduce these resonances but at the cost of increased energy storage which is detrimental to bass performance. Speakers constructed according to these principles can often sound like the life has been sucked out of the music. The enclosure itself is CNC fabricated from 13 layer Baltic Birch plywood with and additional veneer of American Maple on each side for a total of 15 ply and 20mm of thickness. This is both stiffer and lighter than an MDF loudspeaker enclosure of the same size. In addition, the enclosure is braced and cabinet wall vibrations are critically damped through the application of a constrained-layer material on all inside walls.
