Prodigy Audio NB2-8D4 8" 300 Watt RMS Dual 4 Ohm Subwoofer

Prodigy Audio NB2-8D4 8" 300 Watt RMS Dual 4 Ohm Subwoofer is a compact entry-level woofer built for shoppers who want clean, controlled bass in a smaller size without giving up the features that help a sub last and perform well. Sold by AudioSellerz.com, this 8" Prodigy Audio subwoofer is part of the NB2 Series, which Prodigy describes as a first-level subwoofer line with features normally found in higher-end products.

For the 8" model, Prodigy rates the NB2 at 300 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, which is strong for a first-step subwoofer aimed at daily systems and budget-friendly bass builds.

One of the nice things about this woofer is that it is sized for installs where space is tighter but you still want real bass support. Prodigy lists the mounting depth at 5.000", cutout at 7.250", overall diameter at 8.500", and displacement at 0.07 ft3. That makes it a useful option for compact enclosures, smaller vehicles, and everyday systems where a clean 8" subwoofer makes more sense than trying to force in a larger woofer.

Prodigy’s product description also leans into durability. They highlight a double stacked magnet structure, very long voice coil, 500 degree coil adhesive and glue joints, a durable foam surround, strong paper cone, and a cotton blend spider. That combination helps position this sub as more than just a cheap starter woofer. It is built for shoppers who want value, musical low end, and dependable daily use.

On the technical side, Prodigy lists the NB2-8D4 with Re 6.1, Fs 37.335, Vas 6.955, Qes 0.515, Qms 3.417, Qts 0.448, BL 17.879, Mms 117.442 g, sensitivity 83.7, and Xmax 14. If you like digging into the small details before choosing a woofer, this gives you a better look at how the sub is designed instead of forcing you to shop blind.

Prodigy also promotes a 2 year warranty and says subwoofers ship free by ground in the lower 48 states on its product pages, which adds some extra confidence for buyers looking at the brand for the first time.
