INCREDIBLE DISPLACEMENT
Displacement is a direct measure of a subwoofer’s output capability. With more than twice the displacement of most 10-inch subwoofers, the M7-12IB is in a class of its own.
M7 marine subwoofers are purpose-engineered to operate without dedicated enclosures, needing only large volumes of air behind them.
The M7 marine subwoofer easily handles up to 600 watts RMS.
Proprietary motor, suspension and cone modeling systems are employed, resulting in reduced distortion, improved transient performance and stellar bass sound quality.
For long-term use, all models are built to withstand saltwater marine environments and deliver years of listening enjoyment.

| Additional | The enclosure recommendations listed above are external dimensions which assume the use of 0.75" (19 mm) thick material. If you are using 0.625" (16 mm) thick material, subtract 0.25" (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625" (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. When using multiples in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support. We recommend the use of this in a bi-amplified system using high-quality satellites and a high-quality amplifier. We do not recommend the use of this with a passive crossover (coil), as this type of device will adversely affect performance. |
