Rumbling bass from a compact subwoofer

NHT's compact B-10d offers deep, punchy bass that belies its low price and small size. This little wonder packs 300 watts of power and a 10" woofer into a cabinet that measures just over a cubic foot. You may not see where the bass is coming from, but you'll hear powerful, natural lows that put some excitement back into your movie nights and music listening sessions.

Airtight design for solid bass

The B-10d has a built-in Digital Signal Processor (DSP) that dynamically controls the amplifier power, equalization, and crossover functions to ensure that you hear loud, deep, controlled bass without distortion. A special equalizer switch on the back lets you optimize the sub's output for either movies or music.

Unlike most subs, the B-10d uses an acoustic suspension (sealed) cabinet design — a common feature of NHT speakers. It means there's no hole or port to interact with your room, so you'll hear tight bass from this sub no matter where you put it. And since the driver creates some serious pressure inside the closed cabinet, NHT lined the interior with a sheet of aluminum to eliminate any cabinet flex and keep the bass clean.

Classic looks help create a Classic system

The B-10d features a beautiful high-gloss black cabinet made of very dense, rigid MDF. It's finished with ten layers of high-gloss paint that's hand-polished between each coat for lasting beauty. It perfectly matches NHT's Classic family of speakers, so you can easily create a high-end audio system to meet your needs.

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Cons: NONE

Well matched to the NHT Absolute Zero

Crutchfield Customer Review (What's this?)

I paired this with NHT Absolute Zero satellites and Absolute Center. The tonal quality and transition from satellite to sub is seamless. This sub is very musical while still providing the punch a home theater systems needs as long as you are using it in a small room. If your room is larger than 250 sq ft or has an open floor plan then you will not get the visceral punch for HT but for music it should be more than adequate.

I have since swapped this out for the B-12d as I have an open floor plan and am very happy with the entire NHT package.

Overview: The NHT B-10d subwoofer is a compact high-end subwoofer for home theater and music systems. The B-10D sounds powerful and natural while playing either your music or movies. You'll get tight, controlled, articulate, fast, and deep bass out of your soundtracks. Adding a powered subwoofer to your home theater or home stereo system offers plenty of benefits -

  • takes the deep bass load off of your main speakers, so they play louder with lower distortion
  • helps your amplifier by handling the deep bass (your amp handles just the midrange and high frequencies)
  • blends seamlessly with your main speakers and disappears

DSP (Digital Signal Processing )Engine: The integrated DSP engine dynamically controls the powered subwoofer's amplifier power, equalization, and filter functions. As a result, the B-10d plays louder, deeper, with more control. The DSP's built-in limiter and compressor even protects the woofer from being over-driven.

300W BASH Class D Amp: The NHT B-10d powered subwoofer employs a built-in BASH Class D amplifier rated at 300 watts, 4-ohms, 0.5% THD. The digital amplifier design is super efficient and provides powerful, deep bass performance.

Note: Always provide adequate space for ventilation of the subwoofer amplifier. Do not place the powered subwoofer directly against a wall, curtains, or any other surface.

10" Woofer: The NHT B-10d powered subwoofer houses a heavy-duty, long-throw, pulp-cone 10" woofer that has been custom designed by NHT specifically for the B-10d's closed box, acoustic suspension design. The loaded woofer fires forward into the room (not down-firing).

Sealed Enclosure: The NHT B-10d powered subwoofer features a sealed enclosure. It has no holes or ports that can interact with its surroundings making it ok to put it wherever it fits in your space, instead of the other way around. An instead of boomy, sloppy bass - you get deep, accurate, natural sounding bass. The interior walls of the enclosure are lined with a 1mm thick sheet of aluminum to eliminate cabinet flexing, so the B-10D can hit deeper bass notes &  player louder with more control.

Gloss Black Finish: The B-10d powered subwoofer comes beautifully wrapped in the signature NHT gloss black finish.

Mounting Feet: The NHT B-10d comes with four aluminum spiked feet for carpeted flooring (adds approximately 1.1875" to height). There are also four aluminum floor protectors included, in case you have hardwood or tile flooring (adds approximately 1.375" to height). The feet are adjustable to combat against uneven floors.


Subwoofer Volume Control: The NHT B-10d's volume control (min/max) matches the powered subwoofer's volume to the your satellite speaker's output.

EQ Switch: A Unique EQ switch tunes the powered subwoofer for your choice of Movie or Music. The Movie setting augments soundtracks and special effects, while offering higher output (+3dB @53Hz). The Music setting will provide lower, more balanced bass response (0db).

Crossover: The NHT B-10d incorporates a variable low-pass crossover (50-140Hz). The crossover is active for the powered subwoofer's stereo line-level and speaker level inputs. It does not function with the LFE input (you will need to use the low-pass crossover built into your A/V receiver).

Phase Control: A phase control (0/180-degrees) integrates the Super 8's output with your satellite speakers for a more blended, smoother sound.

Auto On/Off: The NHT B-10d will automatically turn-on when it senses an audio signal through its line-level or speaker-level terminals. The powered subwoofer will then turn itself off when there is no sound present for approximately 20 minutes. Or, you can leave the powered subwoofer always on.

USB Wireless Adapter (optional): There is a USB (type-A) connection for use with a future NHT wireless audio adaptor (sold separately).


LFE/Stereo Input: The B-10d has an LFE/RCA input for connection to your receiver's sub out, and stereo RCA inputs for your receiver's line-level preamp outputs.

  • LFE/Subwoofer Input: The most common connection for A/V receivers today is to run a single audio cable from the receiver's Subwoofer or LFE output to the powered subwoofer's LFE/RCA input. The LFE input bypasses the powered subwoofer's crossover control and uses the built-in crossover settings in your receiver.
  • Stereo RCA Input: Some older A/V or stereo receiver only offer preamp outputs. In this case, connect a pair of audio cables from the left/right preamp outputs on the receiver to the two stereo RCA inputs on back of the powered subwoofer. With this connection, you will use the powered subwoofer's integrated crossover controls.

Speaker-Level Inputs/Outputs: There are speaker-level inputs with a high-pass (bass removed) speaker level outputs to connect your satellite speakers, if your receiver lacks LFE/Stereo RCA Inputs. Simply connect a pair of stereo speaker wires from the receiver to the speaker-level input terminals on the powered subwoofer. Then connect a second stereo pair of speakers wires from the powered subwoofer to each satellite speaker. With this configuration, you will use the powered subwoofer's integrated crossover controls. Not only will the crossover prevent high-frequencies from reaching the powered subwoofer, it will prevent low-frequencies from reaching your connected satellite speaker to prevent unwanted distortion.

Universal Power Supply: The B-10d uses a super-efficient, universal power supply (100v-240v, 50/60Hz) to deliver full output anywhere in the world.
