Prodigy Audio NB2-10D4 10" 350 Watt RMS Dual 4 Ohm Subwoofer

Prodigy Audio NB2-10D4 10" 350 Watt RMS Dual 4 Ohm Subwoofer is a sound quality-friendly entry-level woofer built for shoppers who want clean bass, solid low-end support, and a subwoofer that offers better features than you usually expect at this level. Sold by AudioSellerz.com, this 10" Prodigy Audio subwoofer is part of the NB2 Series, which Prodigy describes as a class-leading first-level line with features normally found in higher-end products.

For the 10" model, Prodigy rates the NB2 at 350 watts RMS and builds it with a dual 4 ohm voice coil configuration. The design includes a high temperature 4-layer copper voice coil, black aluminum 2" voice coil former, rear radial coil gap cooling holes, center pole vent, strong stamped steel frame, chrome push terminals, and flat stitched tinsel leads. Prodigy also says the NB2 Series reaches up to 14 mm one-way Xmax at 70% BL, giving this woofer a nice mix of daily usability and real bass capability.

One of the biggest strong points of the NB2-10D4 is that it is built with durability in mind. Prodigy highlights a double stacked magnet structure, very long voice coil, 500 degree coil adhesive and glue joints, durable foam surround, strong paper cone, and a quality cotton blend spider. That helps make it a smart fit for daily driver systems where you want bass that sounds good and holds up over time.

Fitment is also friendly for a lot of everyday builds. Prodigy lists the mounting depth at 5.625", cutout at 9.000", overall diameter at 10.375", and displacement at 0.11 ft3. That gives you a better idea of how this woofer can fit into a compact custom enclosure or a clean budget-minded bass setup without guessing.

On the technical side, Prodigy lists the NB2-10D4 with Re 6.1, Fs 34.295, Vas 21.054, Qes 0.611, Qms 3.24, Qts 0.514, BL 20.11, Mms 165.223 g, sensitivity 84.2, and Xmax 14. If you like looking deeper into the numbers before choosing a woofer, this gives you more useful detail than a basic one-line spec sheet.

Prodigy also promotes a 2 year warranty, a 5-year discounted trade-in program, and says subwoofers ship free by ground in the lower 48 states, which adds even more value around the product.
