39 Subwoofers SW9100 Titanium DVC Pro Series SW9100 Titanium DVC Series The SW9100 Titanium Double Voice Coil (DVC) series subwoofers were developed to meet the need for subwoofers that combine quick response, efficiency and very high SPL performance. These demanding specifications required the development of the radical new technologies used in engineering and building the Titanium series subwoofers. QCA (Quick Change Assembly) technology ECLIPSE QCA exclusive technology has designed the speaker to instantly allow its two sections to separate in the event that the speaker cone gets physically damaged. Simply unlock the two sections with one allen key, twist off the speaker assembly (QCA) and replace with another. Replaceable section Retained section Performance that's a revelation Apart from delivering prodigious amounts of low frequencies, truly excellent subwoofers show what they’re made of by the quality of the low frequencies they produce. Along with moving lots of air, the ability to define the pitch of the low notes is important and to preserve transients is crucial. To do that, subwoofer cones have to be able accelerate fast. The ability of the low-mass high X-max 15. to move faster than a typical 8. woofer but provide bass like an 18. cone is what make the SW9100 Titanium DVC Series deliver such exceptional performance. Solid titanium cone The solid titanium cone adds the best of this metal’s properties to the subwoofer: very high tensile strength, high stiffness to mass ratio, excellent heat dispersion and corrosion resistance. At high power levels, the titanium cone resists the cone flex that causes coloration and distortion, moving air efficiently throughout the full power handling range. 2-inch surround The surrounds are two inches wide to accommodate speaker travel of 3.5 inches peak to peak excursion. Made of special polyether foam that is resistant to ultraviolet radiation and moisture, the surrounds have superior mechanical properties and the low mass needed to produce extremely high excursions. Aluminum voice coil The voice coil former is made of 8/1000. thick aluminum, much thicker than industry standard, to handle the stresses of the high power motor at large displacements. The voice coil wire is a high-temperature aluminum wire, used to minimize mass and maximize thermal radiation. Since the bond between cone and former is thermally conductive, the voice coil heat is quickly dissipated throughout the entire titanium cone. The superior conductivity combined with unparalleled heat dissipation of this voice coil and former assembly means more power transfer into the cone movement instead of wasted heat. Dual symmetrically arranged spiders Two spiders designed with special non-linear Finite Element Analysis (FEA) software are spaced precisely apart to keep the voice coil centered in the motor structure. The woven-in tinsel lead wires are the ultimate in durability and power transfer. The synthetic fabric used to manufacture the spiders is four times stronger than conventional material used in most subwoofers. High force motor structure The motor structure was designed to maximize the force versus displacement curve of high excursion drivers. The motor has a unique shape that results in 20% more force from the same magnets than is normally achieved. The magnetic field is very symmetrical above and below the magnetic gap, contributing to a low distortion and audibly superior driver. Cast aluminum frame The aluminum frame forms the skeleton of the high performance Titanium series subwoofers. Venting below the spiders accommodates the enormous amounts of air that are moved during operation, as well as keeping the motor assembly free of any excess heat. The cast frame also acts as a heatsink to dissipate any additional heat produced from the subwoofers. Triple-stacked magnet ECLIPSE Titanium subwoofers feature a extra-long magnet and pole piece to accurately control woofer travel and enable high-power performance. One-piece machined back plate and pole piece The back plate and pole pieces of a Titanium series subwoofer are machined from a single block of low-carbon steel. This expensive process yields a component part of unparalleled precision and results in a highly efficient magnetic circuit. Aero-vented pole The pole piece of the subwoofer is aero-vented both outside and inside to facilitate the laminar flow of air into and out of the voice coil area for superior motor cooling. Aero-venting also reduces vent noise in high driver travel conditions. The Advantage of Dual Voice Coil (DVC) Dual Voice Coil speakers are designed to maximize space for more flexibility during installation. A dual-voice coil speaker is essentially two speakers in one: two separate voice coils are connected to the amplifier. Depending on the impedance of each voice coil, the two can be combined in a parallel or series configuration to match the impedance ability of the amplifier. The dual voice coil design does not sac...
