Our take on the MTX Blue Thunder BL104
The MTX Blue Thunder Legend BL104 10" subwoofer hits hard and clean, thanks to a tough poly woofer cone and one-piece EPDM rubber gasket/surround. A four-layer voice coil and oversized magnet structure contribute to the power handling capability of this great-looking speaker.
MTX's asymmetrical linear drive technology combines a flat, progressive spider with an extended, vented pole piece to minimize distortion while keeping power handling at high levels. Pull it all together and you're in a hard-rockin' neighborhood! 2-year warranty.Details:
- frequency response 37-150 Hz
- power range 75-250 watts RMS
- peak power handling 500 watts
- sensitivity 85 dB
- top-mount depth 5-1/16"

Woofer: The inverted dustcap is integrated seamlessly with the tinted gray polypropylene cone, for a sleek, high-tech appearance.
EPDM Rubber Surround: The woofer is made with a one-piece EPDM 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. EPDM has the added benefit of being resistant to UV rays for extreme durability.
Oversized Magnet Structure: This woofer has an oversized magnet structure, made with a 33 oz. Strontium Ferrite magnet.
Four-layer Voice Coil: A 2" four-layer voice coil is used for higher power handling.
Asymmetrical Linear Drive: This system improves linearity and permits high output with low distortion.
Extended Vented Pole Piece: The extended vented pole piece provides a more symmetrical magnetic field.
Enclosure Compatibility: This woofer can provide extended bass in sealed, vented and bandpass enclosures (please see "Specifications" section for more information on enclosures).
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 0.75 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 1.5 cu/ft enclosure, so this is the enclosure recommended by Crutchfield. One 3" diameter x 10.75" long port should be used with a 1.5 cu/ft enclosure; a 1.5 cu/ft enclosure with a 3"x 10.75" port has a tuning frequency of 33 Hz.
Single Reflex Bandpass Volume: The bandpass box sizes recommended by MTX with an "S" value of 0.6 range from 0.91 cu/ft to 1.33 cu/ft. The bandpass box sizes recommended by MTX with an "S" value of 0.7 range from 1.14 cu/ft to 1.77 cu/ft. The bandpass enclosure MTX highlights on the woofer specification sheet is a 1.0 cu/ft enclosure with an "S" value of 0.6, so this is the enclosure recommended by Crutchfield. The highlighted bandpass enclosure has a sealed chamber volume of 0.39 cu/ft, a vented chamber volume of 0.53 cu/ft and a 3" diameter x 5.75" 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.
