Thunderbolt Active Subwoofer

The Thunderbolt subwoofer uses the same bass driver technology found in the $126,000 Alón Exotica Grand Reference System. A blend of natural and synthetic fibers was formulated to create a woofer cone that is both extremely rigid, yet lighter in weight than Kevlar, aluminum, magnesium or titanium cones. A voice coil was developed to provide ultra long excursion while dramatically reducing distortion-producing back EMF. An extremely rigid cast frame was engineered to support the huge magnetic structure required to control this outstanding woofer. Alón maintains the stringent rigidity required for the overall system by constructing a cabinet entirely of 1- inch thick MDF panels bonded with wood adhesive and completely clamped during the drying process. To further reinforce the design, Alón created a dual front baffle, "box- within- a- box" construction, which creates a completely sealed, exceptionally rigid cabinet. The Thunderbolt has a front-firing port, so can be placed in various locations ‹ such as in a cabinet ‹ without affecting performance. The amplifier's output stage employs discrete components and runs in Class A/ B mode to provide a level of performance only associated with the finest high- end amplifiers. To properly integrate with a wide range of loudspeakers, the Thunderbolt features a continuously variable low pass crossover (40Hz to 160Hz) and a continuously variable phase control (0 to 180 degrees). A sensing circuit allows the subwoofer to be automatically powered on and off by the preamplifier or receiver. The result is an innovative subwoofer that has both the high- speed attack of a small woofer and the enormous energy at low frequencies of very large woofers. The Thunderbolt Subwoofer provides powerful and dynamic yet detailed bass reproduction to recreate reality at all sound levels ‹ from very soft and delicate to very loud and powerful. This wide dynamic range is lacking in other subwoofers, both large and small.

Specifications
System Type: Powered, front firing ported subwoofer Front firing allows it to be placed in various locations, such as in a cabinet, without affecting performance. Driver Diameter: 12 inches We developed a unique driver with the attack speed of a small woofer and the very deep bass of a large one. Driver Construction: A blend formulation consisting of both natural and synthetic fibers Highly rigid with lower mass than Kevlar, aluminum, magnesium or titanium drivers. Response: 20Hz to 160Hz We roll off the response below 20Hz to eliminate spurious low frequency noise found in some digital discs. Crossover Frequency: Continuously variable low pass 40Hz to 160Hz, fixed high pass 100Hz The wide range, low pass crossover allows proper integration with a wide range of large and small speakers. Phase: Continuously variable from 0 to 180 degrees Allows subwoofer's sound wave to properly integrate with loudspeaker, independent of room placement. Power:Manual or auto on/off, detachable power cord, 120 or 240 Volt operation Sensing circuit allows subwoofer to be automatically powered on and off by preamplifier or receiver. Amplifier: Fully discrete Class A/B outputs Wattage output is ample enough to provide more low-end impact than any competitor's subwoofer. Finish: Black or cherry wood veneer The cabinet is handcrafted to very high wood finishing standards to compliment the finest of furnishings. Cabinet Size: 16" H x 16"W x 18"D; 41cmH x 41cmW x 51cmD (20"/56cm deep with allowance for grille and power cord) Small size allows for ease of placement in any room. Weight: 85 lbs/39kg, net
