The most important of the many elements contributing to this achievement are Descent i's TriLinear BalancedForce driver configuration and its advanced triple-servo monitoring and control system. Three identical drivers high-performance, high excursion 10-inch aluminum-cone units in this case are mounted precisely 120 degrees apart from each other in the cabinet.
As a result, their reaction force vectors exactly cancel, virtually eliminating cabinet resonance and vibration. Gone with them are the cabinet-radiation coloration and bass blur that afflict even the best conventional subwoofers. The triple-servo system, meanwhile, ensures that the output from the drivers themselves the output we want is always an absolutely faithful replica of the audio input signal. It's the power of a charging rhino expressed with the nimble athleticism of a cheetah performance unsurpassed in any category and unrivaled overall.
No matter how well a subwoofer performs on its own, ultimate satisfaction depends on seamless integration with the rest of the audio system. With that in mind, we've outfitted Descent i with easily accessible top-mounted controls and with LFE and two-channel inputs that allow separate optimization for home-theater and stereo operation in the same system. Descent i is a truly no-compromise subwoofer, regardless of application.
Each of Descent i's high-resolution drivers combines an extremely rigid 10-inch aluminum-cone diaphragm with a high-intensity magnet structure to achieve huge excursion and output capability without sacrificing detail. By eliminating cone flexure, even at long voice-coil excursions, aluminum diaphragms help our advanced-technology bass drivers achieve the very low distortion necessary for proper blending with MartinLogan electrostatic speakers.
Descent i has three 10-inch aluminum-cone drivers, each weighing 12 pounds and possessing a maximum peak-to-peak excursion range of 1.2 inches. That works out to a total displacement of 30 cubic inches typical for most high-quality subwoofers. Descent i has three of these drivers, however, yielding the equivalent acoustic power of a 36-pound driver with a maximum peak-to-peak excursion of 3.6 inches and a total displacement of 90 cubic inches. And because the thermal load is distributed over three voice coils instead of concentrated in one, the system is less influenced by to temperature-induced compression. The single-driver alternative would be an extraordinarily robust 18-inch unit, which by virtue of its size and very long excursion would inevitably generate considerably higher distortion. Descent i enjoys all the advantages of the smaller, more refined drivers while achieving the output capability of a huge 18-inch driver.
