* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied. 
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is "louder".

Sealed Enclosure Specifications

Table_Image
Wall Thickness0.625 in / 16 mm
Front Baffle Thickness0.625 in / 16 mm
Volume (net int.)0.75 cu ft / 21.2 L
External Width (W)15.5 in / 394 mm
External Height (H)12 in / 305 mm
External Depth (D)9.75 in / 248 mm
F360 Hz
Fc80.73 Hz
Qtc1.155

* The enclosure recommendations listed above are external dimensions which assume the use of 0.625 in (16 mm) thick material. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure.

* All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account.

Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.

When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van.
