Prodigy Audio NB2-12D4 12" 400 Watt RMS Dual 4 Ohm Subwoofer

Prodigy Audio NB2-12D4 12" 400 Watt RMS Dual 4 Ohm Subwoofer is a great fit for shoppers who want clean daily bass, solid low-end response, and a subwoofer that gives you more than the usual entry-level features. Sold by AudioSellerz.com, this 12" Prodigy Audio subwoofer is part of the NB2 Series, which Prodigy describes as a class-leading first-level subwoofer line with features normally found in higher-end products. Prodigy rates the 12" model at 400 watts RMS and builds it with a dual 4 ohm voice coil design.

The NB2-12D4 is built around the features that help a woofer stay reliable and play well in a real daily system. Prodigy highlights a double stacked magnet structure, very long voice coil, high temperature 4-layer copper voice coil, black aluminum 2" voice coil former, rear radial coil gap cooling holes, and a center pole vent to help move heat out of the coil gap. The woofer also uses a durable foam surround, strong paper cone, quality cotton blend spider, chrome push terminals, and flat stitched tinsel leads. Prodigy says the NB2 line reaches up to 14 mm one-way Xmax at 70% BL with 2" of mechanical movement clearance peak to peak.

Fitment is friendly for a lot of real-world 12" bass builds. Prodigy lists the mounting depth at 6 3/4", cutout at 11 1/8", overall diameter at 12 1/2", and displacement at 0.13 ft3. That gives you a solid starting point whether you are planning a custom enclosure, replacing an older 12" woofer, or putting together a budget-friendly setup that still sounds right.

On the spec side, Prodigy lists the NB2-12D4 with Re 6.2, Fs 28.37, Vas 55.392, Qes 0.522, Qms 3.662, Qts 0.457, BL 21.268, Mms 216.268 g, sensitivity 85.4, and Xmax 14. If you like having more than just basic RMS and impedance numbers before choosing a woofer, this gives you a better look at how the sub is designed.

Prodigy also promotes a 2 year warranty, a 5-year discounted trade-in program, and says subwoofers ship free by ground in the US48 states, which adds even more value around the product.
