NHT B-12d Powered Subwoofer

The new B-12d subwoofer is a compact, smart and affordable high-end powered subwoofer for home theater and stereo music systems that says you're dead serious about good sound. Everything we’ve learned in our 23 years of building great speakers was rolled into the best powered twelve-inch subwoofer we’ve ever built.

Outside - The B-12d subwoofer is a compact 14" cube - barely bigger than the 12” driver contained within and packs a huge sonic punch. The B-12d is an acoustic suspension design - no holes or ports to interact with its surroundings. As a result, it can be placed wherever it fits in your room without sacrificing sound quality. Four aluminum cones are included to keep it from skidding around on carpeted floors, and rubber pads to keep it from doing donuts on slippery floors. Like all NHT Classic speakers, the B-12d comes beautifully wrapped in NHT’s signature 10-coat piano gloss black finish.

Inside - Start with 500 (bone crushing) watts of really smart, efficient power. For the techies, we use a BASH PWM (Class D) amplifier design with dedicated switching power supply. Unlike traditional amplifiers, the B-12d’s super-efficient design converts most of the electricity coming from your wall outlet to bass, instead of wasting it as heat. The brains of the B-12d are in its factory-programmed DSP (digital signal processing) engine. The DSP controls the 24 db/octave phase-perfect adjustable low-pass filter, internal EQ, Boundary EQ, and even a sophisticated limiter and compressor. As a result the B-10d subwoofer goes lower and plays louder with better control than any 12" sub we've ever built.

The speaker itself is a long-throw, pulp cone design with a heavy-duty butyl rubber surround. Both the cone and the massive motor structure it’s attached to were custom designed by NHT specifically for the B-12d. This massive woofer creates some very high pressure inside the B-12d’s sealed enclosure, so we lined the interior cabinet walls with a 1 mm thick sheet of aluminum to eliminate any trace of cabinet vibrations.

Backside – Everything you need to integrate the B-12d with your stereo or surround sound setup can be found around back - LFE inputs for your receiver’s sub out, stereo line inputs for your 2-channel rig, and an LFE out so you can add another B-12d. There's a variable phase control for matching the B-12d with your other speakers, and NHT’s Boundary control that electronically "moves" the subwoofer for best sound without physically moving it. An automatic power mode turns the B-12d on and off select "Always On" for remote power switched systems. The B-12d 's smart, power supply automatically adjusts to deliver full output anywhere in the world on a diet of 100v to 240v at 50 or 60Hz.

The Sound – Like all NHT subwoofers the B-12d sounding musical and natural while playing music and scary on movies. One B-12d in your system is pretty serious stuff. Two B-12d’s will deliver the ridiculous, even in large rooms. If want a subwoofer that will turbo-charge your system dynamics, blend perfectly into your system and providing smooth, seismic low end – stop searching and start buying.
