Product Description

Product Description

300 watt 10" powered subwoofer with DSP

From the Manufacturer

The new B-10d subwoofer is a really compact and affordable high-end powered subwoofer for home theater and stereo music systems that says you're dead serious about good sound. It combines 23 years of speaker building know-how with the best subwoofer technologies to deliver more sonic bang for the buck than any compact subwoofer NHT has ever built.

The NHT B10d Classic Subwofer
The B-10d is simply elegant in NHT's piano gloss black finish and all business

Buying any NHT speaker means you care about getting the best speaker value for your hard earned money. It means and you care about quality craftsmanship and high-end performance. It means you're ready to join the family of fanatics who love music, movies and the best gear that produces them. Welcome to the club--Now Hear This!

Acoustic Suspension Design

The B-10d is an acoustic suspension system, which means that the box itself is sealed; no ports or holes to spoil the fun. Acoustic suspension systems use the air (natures most perfect spring) trapped in the box itself to control and damp the speaker's movement - a bit like the shocks on a car. The results are lower distortion, higher power handling, and tighter deep bass tones.

What should a great subwoofer do for your system? It should relieve your receiver's amplifier of the burden of producing deep bass through your main speakers--allowing it to run cooler, sound better, and last longer. It should reduce your system's overall distortion by handling the lowest frequencies and leaving the midrange and high frequencies to your other speakers. It should improve the system dynamics. It should seamlessly integrate into your system and simply disappear. It should be able to do all these things without visually dominating your living room. The B-10d does all this and more with ease.

Compact Cabinet Design with Piano Finish

The B-10d powered subwoofer is a compact 12.6" cube--a bit smaller than a 12-pack of your favorite bottled beverage. Don't let its compact size fool you though; the B-10d packs a keg's-worth of punch into its tiny enclosure. Like all NHT Classic speakers, the B-10d comes beautifully wrapped in NHT's signature 10-coat piano gloss black finish.

A compact subwoofer with low distortion, high power, and deep bass tones

Since the B-10d has no holes or ports that can interact with its surroundings, it's okay to put it wherever it fits in your space. It comes with four cool looking, yet functional aluminum feet to keep it anchored to carpeted floors. Four aluminum floor protectors (pucks) are also included that slip under the cones to keep it from doing donuts on slippery hardwood or polished concrete floors.

Under the Hood

The B-10d starts with 300 watts of really smart, efficient power, delivered by a BASH PWM (Class D) amplifier design with dedicated switching power supply. What's that mean? Unlike traditional amplifiers, the B-10d's amplifier is super-efficient and converts just about all of the electricity coming from your wall outlet to bass, instead of wasting it as heat. Bottom line? Rock out and stay (cool) green at the same time.

The real voodoo can be found in the B-10d's dedicated DSP (digital signal processing) engine. The DSP engine controls everything going on in the subwoofer including a phase perfect equalizer for ruler flat bass response and 24/dB per octave low and high pass signal filters to keep out unwanted frequencies. A digital compressor and limiter in the DSP maximizes output and minimizes any overload danger at the same time. Rocket science all preprogrammed by NHT so you can just enjoy.

Also in the B-10d's DSP is a unique feature called DRC (Dynamic Range Control). The DRC program dynamically controls the amplifier current at all speaker impedances to insure that the B-10d slams at all bass frequencies. No rulers, microphones or math. NHT engineers expertly programmed everything at the factory. As a result the B-10d subwoofer goes lower, plays louder with way better control than any 10" sub on the market.

The NHT B10d Classic Subwoofer
Easily integrate the B10d into your current stereo system

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-10d. As you can imagine, this massive woofer creates some very high pressure inside the B-10d's sealed enclosure. NHT thought of that too. They lined the interior cabinet walls with a 1 mm thick sheet of aluminum to help make the cabinet stiff, strong and thereby eliminate any trace of cabinet vibrations.

The Ins and Outs

It's easy to integrate the B-10d with your current stereo or surround sound setup. The B-10d has LFE inputs for your receiver's sub out, left and right line inputs for your fancy 2-channel integrated amp, and even a set of speaker level inputs and outputs so you can connect to your vintage silver-faced stereo receiver too. There's a phase switch for matching the output timing of the B-10d with your main speakers, and a two position "Movie" or "Music" EQ switch for adding a little extra low-end oomph or keeping thing flat. There is no power switch on the B-10d - just auto on/off or always on. You don't need a power switch because the B-10d uses less than flashlight power with there is no signal. In fact, the B-10d's smart power supply design automatically adjusts itself to deliver its full load of bass output anywhere in the world on a diet of 100v to 240v at 50 or 60Hz.

Wireless Option

NHT has designed the B-10d and B-12d to be wireless ready via the back panel USB connector. The back panel USB connector conveniently supplies the wireless receiver both power and signal input capability. The optional wireless kit will available July 2011.

The Sound

Like all NHT subwoofers the B-10d sounds powerful and natural while playing either music or movies. It's tight, controlled, articulate, fast, deep, and even a bit scary when the soundtrack demands it. If you're shopping for a subwoofer that will seamlessly blend into your system, completely disappear most of the time, not dominate your room and always fool you into thinking all the sound is coming from your main speakers--stop searching.

It rocks! My home theater/music room is about 10' x 15' and this model supplies all the bass I need. Plus, I love the fact that the unit was made locally (in Benicia - SF Bay Area). The footprint of the unit is fairly small and fits nicely in the corner. And boy, does it ever deliver the thunder!

I have had this subwoofer for about three weeks and I am delighted with it.

SOUND: This does not sound like there's a subwoofer in the room adding something. Instead, it seems to seamlessly extend the sound of my wall-mounted Martin Logan speakers. This is a home theater arrangement with right and left speakers mounted on either side of my 60-inch TV and the center channel speaker centered below the TV. The subwoofer is in a corner off to the side of the TV wall.

My Onkyo receiver has a built-in program to set the levels of all speakers, so it was extremely easy to set this up properly. Sonically, this subwoofer seems to disappear, and I certainly cannot detect what sounds come from it and which from the main speakers. I have watched a couple of action-adventure movies to see how well this NHT can dip into low bass range. There is more than ample low frequency material, and I have not heard any distortion.

My wife remarked the other night that she could feel the bass in her bones. This evening she said she could hear it and feel it when she was upstairs taking a shower. And it was not turned up very loud. I don't recall her ever saying anything like that before with the subwoofers I previously had.

SETUP: The unit was nicely packed at the factory with just the accessories necessary. Unlike some electronic products, this one was not burdened with cords and other things that would cover every conceivable eventuality. Because my receiver made the proper adjustments, I had to do very little except plug this in and connect it to the receiver, then follow the receiver's instructions.

APPEARANCE: I was nervous about whether my wife would accept a black box in the corner of our living room, which until now has been decorated with a plant.

I wouldn't have even considered this lil mighty mite, but for the fact the svs sb12 sub I ordered directly from SVS hadn't got held up in customs in Canada, with that being said I ordered the nht b 10d not knowing how long it would take to get the svs. And low and behold they both arrive this morn (10/19)....let's have some fun, I first hooked up the svs sb12 it runs down to 30hz I set it at 35hz & set the volume to half set up btw is emotiva xrt6.2 towers an xpa 3 amp usp 1 pre amp & erc-2 cd player, my listening area is relatively small 9wx12Lx7h....the reference cd's I chose was michael Jackson's I'm bad cd there's very good low bass highs & midrange on this cd & earth wind & fires latest cd, then I chose several diff movie trailers from my Apple TV. The svs sb12 nsd performed well giving me a nice clean thump, it's a sealed 12" 400 watt rms sub so there's not a lot of overhang when it hits those low notes it's a very musical sub & it performed well In the movie arena, but OMG! This little 10" blew me away. The nht b 10d is a little beast! only plays down to 50hz but this lil guy can rock the house! On Michael Jackson's I'm bad it had my sofa shakin, it too is a very musical sub & it has an eq switch to change between music & movie mode & you can really hear the difference when you use this feature. So in my test between the to subs I used the the same songs & same movie trailers to try & create an equal playing field, the nht for its size was really out performing the svs 12... I did however change the x-over setting on the svs to play the same as the nht (50hz) so now the battle is pretty close, it's so close In fact I'm bringing in a second set of ears to help me decided on which one to keep.Read more ›
