Features
Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils, offering wiring flexibility. When the voice coils are wired in parallel the woofer presents a 2-ohm load. When the voice coils are wired in series the woofer presents an 8-ohm load.
Terminals: The woofer features two pair of heavy-duty spring post terminals which can accept single or dual (standard 3/4" width) banana plugs, pin connectors, or bare wire up to 10-gauge.
Inverted Apex Surround: The new Inverted Apex surround allows increased cone surface area, creating more air movement and higher SPL.
Progressive Suspension: The progressive suspension controls excursion at high power, thus reducing distortion and improving sound quality.
Spider Plateau Venting: Heat from the voice coil is vented through vents that surround the back of the spider. As the woofer travels back and forth, cool air is pulled in and heated air is pushed out.
Enclosure Compatibility
Sealed Box: For the best possible sound quality where space is a premium MTX recommends a sealed enclosure with an internal volume of 1.5 ft³. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
Vented Box: The recommended vented box has a net internal volume of 2.48 ft³ with a slot port 14-1/2" x 2" x 20". Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power.
