This is the Wavtech thinPRO10-4 10" / 750W RMS / Single 4 Ohm Shallow Subwoofer with Grille.

• The thinPRO10 is the ultimate paradox. There really isn’t anything else like it. Our Patent Pending design changes the game for what is possible with a shallow subwoofer. With a mounting depth of less than 3”, if it won’t fit in the desired location, you probably aren’t putting a subwoofer there. The dual mirrored NBR spiders and axial force transfer assembly allows for unparalleled performance in a multitude of applications.

• The FEA optimized dual gap motor structure features a massive motor with double stacked strontium magnets. This maximizes flux density and control for an impressive 20mm of linear xmax. The honeycomb cone is made of a composite Nomex® and glass fiber, making it incredibly rigid and very lightweight. The 4.5” voice coil, available in 2 or 4 ohm, provides a powerful moving force with 750W RMS power handling.

• The point of a shallow subwoofer is maximum performance in a small enclosure. The thinPRO10 is perfect in both small sealed and ported enclosures. Sealed box sizes range from 0.25-0.8cu ft, with the sweet spot at 0.35cu ft. Ported enclosures range from 0.8-1.5cu ft, with 1.0cu ft recommended for optimum performance.
