Square Polypropylene Cone: The Thunder Square 55 features a
painted gloss-black metallic, stitched polypropylene square cone with a raised
MTX Audio logo. Polypropylene is lightweight yet durable and offers efficient,
dependable bass response. A square subwoofer provides16% to 20% more area than
a conventional round subwoofer.
Rubber Surrounds: The Thunder Square series woofer features a
rubber surround that is stitched directly to the cone for durability. The woofer's
rubber surround uses FEA optimized roll geometry to maximize excursion without
sacrificing cone surface area.
Voice Coil: The woofer's voice coil is wound with 428-degree
High Temperature wire to ensure reliability even at loud volumes.
Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice
coils that offer flexibility in wiring. When the voice coils are wired in parallel
with each other, the woofer presents a 2-ohm mono load. When the voice coils are
wired in series with each other, the woofer presents an 8-ohm mono load. In addition,
each coil may be connected to a different amplifier channel and each channel will
see a 4-ohm load.
Spider Plateau Venting Technology: The Thunder 55 woofer uses
proprietary Spider Plateau Venting technology which helps push out air out of the
voice coil and bring cool air in, adding to the reliability of the subwoofer and
keeping it cool even in the hottest vehicles.
Asymmetrical Linear Drive System: The woofer's Asymmetrical
Linear Drive System combines a flat progressive spider with an extended pole piece
to reproduce smooth, linear motion for incredibility crisp, clean sound.
Stamped Basket: The TS55 subwoofer has a black stamped basket
design for structural strength, a stamped back panel with MTX's aggressive looking
Gothic logo, and a large ABS plastic boot protecting the woofer's magnet.
Dual Terminals: The square woofer features two pair of nickel
plated, spring-post terminals for attaching your speaker wire from your amplifier.
