It combines NHT's over 23 years of speaker building know-how with their best subwoofer technologies to deliver more sonic bang for the buck than any twelve-inch subwoofer the company has ever built. The B-12d is simply elegant in NHT's piano gloss black finish but underneath, 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 DesignThe B-12d is an acoustic suspension system, which means that the box itself is sealed with no ports or holes to spoil the fun. Acoustic suspension systems use the air trapped in the enclosure 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 than any ported sub can offer.What should a world class 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 managing 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-12d does all this and more with ease.Compact Cabinet Design with Piano FinishThe B-12d powered subwoofer is a fairly compact 14" cube--barely bigger than the 12" driver contained within. The size of the sonic impact on your system is more like garage sized subwoofer cube. Like all NHT Classic speakers, the B-12d comes beautifully wrapped in NHT's signature 10-coat piano gloss black finish.The B-12d's cabinet has no holes or ports to interact with its surroundings making it okay to put it wherever it fits in your space. It comes with four cool aluminum feet to keep it anchored to the floor when doing its thing on carpeted floors. Four aluminum floor "pucks" are also included to slip under the cones to keep it from doing donuts on slippery hardwood and polished concrete floors. Note: The included cones can be used on hard floors as well, but they are sharp and will scratch or dimple the floor.Under the Hoodthe B-12d starts with 500 watts of really smart, efficient power, delivered by a BASH PWM (Class D) amplifier design with dedicated switching power supply. Unlike traditional amplifiers, the B-12d's super-efficient design converts just about all of the electricity coming from your wall outlet to bass, instead of wasting it as heat so you can rock out and stay green at the same time. NHT's best subwoofer technologies deliver more bang for the buck than any other 12" subwoofer The real voodoo can be found in the B-12d's dedicated DSP (digital signal processing) engine. The DSP engine controls everything including a phase perfect equalizer for flat bass response and 24/dB 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.Also in the B-12d's DSP is a unique feature called DRC (Dynamic Range Control) that dynamically controls the amplifier current at all speaker impedances to insure that the B-12d slams at all bass frequencies. No rulers, microphones or math. NHT engineers have expertly programmed everything at the factory. As a result the B-12d subwoofer goes lower and plays louder with way better control than any 12" sub on the market. It's easy to integrate the B12d with your current stereo or surround sound setup 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. As you can imagine, this massive woofer creates some very high pressure inside the B-12d's sealed enclosure, so NHT lined the interior cabinet walls with a 1 mm thick sheet of aluminum to help hold everything together and eliminate any trace of cabinet vibrations.The Ins and OutsIt's easy to integrate the B-12d with your current stereo or surround sound setup. The B-12d has LFE inputs for your receiver's sub out, line inputs for your fancy 2-channel pre amp connection. There's a phase switch for matching the output timing of your subwoofer with your main speakers, and a two position "Movie" or "Music" EQ switch for adding a little extra low-end oomph, or not. An automatic power mode allows the B-12d to turn itself on and off when it hears a signal from your system or select "Always on" if you switch the power remotely. The B-12d's smart, switching power supply automatically adjusts to deliver its full output anywhere in the world on a diet of 100v to 240v at 50 or 60Hz.Wireless OptionNHT 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 SoundLike all NHT subwoofers the B-12d 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.Technical SpecificationsWoofer: 12" paper cone, long throwFrequency Response: -3dB 27Hz - 130Hz, -6dB 25Hz, -10dB 23HzDistortion: <1% above 48Hz, 1W equivalentAmplifier Power: 500W, 4 ohms, <0.5% THDPeak Output: @1M 120dB @58Hz, 115dB @40Hz, 112dB @30HzFixed Low Pass: 200Hz, 6th orderInputs: LFE on RCA, L and R on RCAOutputs: Speaker level L and RCabinet Size: 14" x 14" x 14" (H x W x D)Cabinet Material: 18mm MDF with 1mm Aluminum sheet (interior)Product Weight: 33.7 lbs.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    NHT speakers are consistently world class..Excellent Sub
  

*by B***R on Reviewed in the United States on January 13, 2013*

I just submitted and identical review for the NHT Absolute Towers and the comments around the sub/product and the buying experience are the same. This is a world class subwoofer for a very fair price, I call it value. Company supports the product, is there for advice simply send a quick email and it's as though you doing text messaging..yes, that quick.Summary is this sub is as good as 98% of the people listening to albums or movie sound tracks will ever need. To spend anything beyond this or attempting to buy sonmething more expensive would be a waste. This is a class D amp'd sub, piano gloss black, line in of LFE, all the crossovers you'll need, technically as good as anything. Looks tremendous and matches timbre with the Absolute Towers, and TwoC Center/Three C Center...More on the company and a higher level review on other NHT's I've recently purchased is below.These are likely the best kept secret from the mass markets of buyers who flock to highly marketed brands such as Polk, Klipsch, JBL etc...all of which are fine product. However, if you want world-class quality, looks, sound, service, and value then buy NHT speakers.1) I've been buying speakers, receivers, Hi-Fi gear for the past 35 years and have had the typical lines and as the wallet allowed I would upgrade. Crutchfield carries this speaker line as well and frankly that is how I found their website and spoke with the founder, Chris Byrne. Well, that did it as how often can you speak with someone who knows the supply chain from start to finish...Never. These folks are quality people and provide world-class service and product.2) The Absolute Towers are a glossy black, 10+ coats of piano black, acrylic etc...gorgeous...solid, look better than anything I've seen. These feel and sound like they should be $1,200-1,500 each!3) Sound: phenominal, and certainly what you drive them with will make a difference along with the music source: turntable-excellent, Yamaha higher end CD player-excellent...warm, crisp, excellent sound field,4) Value/Service....cannot be beat. This is a California based company, quite small so you get the personal touch. You will end up at some point, if you like, speaking or emailing with Chris or John (both founders of the company). Briliant guys, know their product and respond in minutes via email, maybe an hour if they are tied up...World class service, advice and people and product...No, I don't work for the company. I'm a white collar guy from Chicago who wants to share a great story about a company that earns it everyday. Spend your money with them and step up to world class speaker quality for mass market pricing. Seriously...I don't write review hardly ever...but these guys deserve the press for what they deliver.BTW...I started with "trying" the Absolute Towers after speaking with Chris, was very impressed with our honest/sincere conversation and decided on the $400 center...Then two weeks later bought the Absolute Wall mount speakers and in spite of having 3 subwoofers already, bought the b 12-d subwoofer...so now I have the complete 5.1 system driven by a new Denon 1713, LG BluRay, Yamaha CD (higher end) CD player, with a Vizio 50' plasma...The sound will make you smile once you put on your favorite album, movie, CD...kick back with a cool one and enjoy the great decision you made....60 day return policy so you have nothing to lose...buy them.
