High performance meets heavy-duty sound in MTX's top-of-the-line Thunder8000 series T8104A 10" subwoofer. And we mean heavy — the strontium ferrite magnet alone tips the scales at a beefy 102 ounces! With that kind of power at hand, you know this sub will deliver the fullest bone-shaking bass MTX has to offer.

The T8104A is the picture of strength — the injection-molded, spun-aluminum cone has 12 polished ribs to increase stiffness and manage incredible sound pressure levels. A sturdy 12-leg, die-cast aluminum basket anchors the extra-stable structure. A durable black NBR (Nitrile Butadiene Rubber) surround fends off moisture and temperature extremes for long-term speaker accuracy.

Even when the music is hot, this sub stays nice and cool with a four-layer, 2-1/2" voice coil. You'll also find small vents around the frames — spider plateau venting — to help dissipate hot air under the spider and curb distortion.

Details:
  • asymmetrical linear drive system (ALDS) — spreads stress evenly across the suspension for high output with low distortion
  • spun aluminum cone has 12 stiffening ribs for extended power handling
  • one-piece gasket/surround made of thermal-pressure-formed Nitrile Butadiene Rubber (NBR) for superior sonic accuracy and greater overall durability
  • extended pole piece for a more symmetrical magnetic field and smoother sound
  • computer-optimized five-roll spider design combines extreme excursion with exceptional linearity, for maximum output and minimum distortion
  • die-cast aluminum basket resists sound-altering resonance without pulling electromagnetic energy from the magnet as a steel basket can
  • heavy-duty, gold-plated push-type speaker terminals provide extra-secure connections, ensure maximum signal integrity, and resist corrosion
  • frequency response 24-150 Hz
  • power range 75-400 watts RMS
  • peak power handling 800 watts
  • sensitivity 84.2 dB
  • top-mount depth 5"
  • sealed box volume 0.5 - 1.0 cubic feet
  • ported box volume 1.0 - 2.0 cubic feet
  • Recommended Q-Logic Box Type: 1, 3
  • 1-year warranty

Priced per speaker

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Features

Cone Cosmetics and Materials: The woofer cone is made of Mica-filled polypropylene with an aluminum finish with 12 stiffening ribs for improved cone stiffness and higher mechanical power handling; the ribs increase cone durability and performance.  Concentric rings are molded into the cone and dust cap surfaces to give them a machined appearance.  "MTX Audio" is embossed on the poly dust cap.

12-leg Die Cast Aluminum Basket: The basket was built with the strength and stiffness required to handle the demands of enormous bass without flex or distortion.

Oversized Magnet Structure: This woofer has an oversized magnet structure, made with a 102 oz. Strontium Ferrite magnet.

NBR Rubber Surround: The woofer is made with a one-piece NBR (Nitrile Butadiene Rubber) surround and gasket combination.  When bottom-mounting the woofer, the one-piece surround and gasket make an air-tight seal, to prevent any loss of performance due to air leaks around the woofer.  When the woofer is top-mounted, the one-piece surround and gasket combination enhances the overall cosmetic appearance of the woofer.  NBR has the added benefit of being resistant to ozone and UV rays for extreme durability. 

Computer Optimized Progressive Roll Spider (COPR):  A "five roll" spider design is used to maximize the linear region of the speaker's movement.

Four-layer Voice Coil: A 2.5" four-layer voice coil is used for higher power handling.

Spider Plateau Venting: Small vents are located around the base of the frame to prevent hot air from being trapped between the spider and the back plate. The vents help cool the voice coil to increase power handling and reliability.

Asymmetrical Linear Drive: This system improves linearity and permits high output with low distortion.

Extended Pole Piece: The extended pole piece provides a more symmetrical magnetic field.

Spring Post Inputs: The inputs are spring post connectors that will accept bare wire, tinned wire or wire terminated with pin connectors.

Enclosure Compatibility: This woofer can provide extended bass in sealed, vented and bandpass enclosures (see below for more information on enclosures).

Enclosure Compatibility

Recommended Sealed Box Volume: The sealed box sizes recommended by MTX range from 0.5 cu/ft to 1.0 cu/ft.  The sealed enclosure MTX highlights on their spec sheet is a 0.63 cu/ft enclosure, so this is the enclosure recommended by Crutchfield.

Vented Box Volume: The vented box sizes recommended by MTX range from 1.0 cu/ft to 2.0 cu/ft.  The vented enclosure MTX highlights on the woofer specification sheet is a 1.25 cu/ft enclosure, so this is the enclosure recommended by Crutchfield.  A 3" diameter x 16" long port should be used with a 1.25 cu/ft enclosure; a 1.25 cu/ft enclosure with a 3"x 16" port has a tuning frequency of 31 Hz.

Single Reflex Bandpass Volume: The bandpass box sizes recommended by MTX range from 0.66 cu/ft to 1.15 cu/ft.  MTX highlights two bandpass enclosures on the woofer specification sheet.  One highlighted enclosure has an "S" value of 0.6, and the other highlighted enclosure has an "S" value of 0.7.  The highlighted bandpass enclosure with an "S" value of 0.6 is a 0.77 cu/ft enclosure, with a sealed chamber volume of 0.23 cu/ft, a vented chamber volume of 0.31 cu/ft and a 4" diameter x 19" long port.  The enclosure with an "S" value of 0.7 is a 0.91 cu/ft enclosure, with a sealed chamber volume of 0.28 cu/ft, a vented chamber volume of 0.43 cu/ft and a 4" diameter x 16" long port.

Note: The bandpass enclosure with the higher "S" value produces a more narrow bandwidth with better transient response; the enclosure with the lower "S" value produces a wider bandwidth at the expense of transient response.
