More bass from a smaller space
Most “thin” subwoofers suffer from some combination of limited excursion (“Xmax”), limited power-handling, and or require a large box, despite having shallow-mounting depth. Alternatively, they may “work” in a small enclosure, but have a rather high Fs (resonant frequency), so they are not really true, high-excursion “subwoofers.”
Taking a page from the audio history books, our team recognized that the most proven way to get more bass from a smaller space, was to employ what is referred to as an “Isobaric” design.
Our solution was both elegant and simple; create a family of drivers that duplicated the physics of the pair of drivers, but in a single, compact driver, which would have both the long excursion, power-handling, as well as the typically mutually exclusive combination of a low Fs, as well as small VAS (the required air-space to hit the Fs).
Long excursion, power-handling, slim depth
The GTS “21″ series perhaps represents the ultimate development of this concept, as it delivers the best balance of incredible low-frequency extension, from a very small enclosure, yet retains remarkable efficiency, allowing it to perform optimally with just a couple hundred watts. However, as the “21″ series suggests, it’s like two (2) drivers in one, so it will take 400 – 500 watts RMS, without complaint, making it an ideal solution for today’s high-power monoblock amplifiers.
- Custom-tooled, low-profile frame, featuring “FAB-RAC,” bi-radial cooling vents.
- Monolithic motor design, featuring no axial rear vent, permits minimal mounting depth.
- Multi-layer, pure-copper high-power voice coil provides huge thermal power-handling.
- Unique, Aluminum Flux Modulation Device (“FMD”) reduces inductance and distortion.
- Advanced, Kevlar composite, multi-layer, sandwich “CLS” cone is near perfect piston.
- High-quality SBR rubber surround, permitting up to 2″ of peak-to-peak excursion.
