The thinPRO10 is the ultimate paradox. There really isn’t anything else like it. 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 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 0.4-1.0cu ft, with 0.6cu ft recommended for optimum performance. thinPRO10 Features 750 Watts RMS Power Handling 2.9” Mounting Depth 4.5” Voice Coil 4-Layer Winding on Vented Polymide Composite Former Protective Grille (TP10G Sold Separately) Honeycomb Nomex® and Glass Fiber Cone FEA Optimized Dual-Gap Motor Structure Double-Roll NBR Surround Mirrored Internal NBR Spiders 8AWG Push Terminals Vented Cast Aluminum Frame Dimensions: 9 1/8in (232mm) Standard 10” cutout Specifications: General Specifications: Nominal Size: 10" Nominal Impedance: 4 ohm Power Handling: 750W RMS, 2250W Peak Recommended Power range: 250W-750W RMS Frequency Response:
