Product Information

Upgrade! - Trade-in your old NHT subwoofer! Download the Sub Upgrade Program on the right hand side for more information. 

The new B-12d subwoofer is a compact high-end powered subwoofer for home theater and music systems that says you're dead serious about great sound. Everything we’ve learned in our 23 years of speaker building was crammed into the best twelve-inch sub 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 air suspension design - no ports to interact with its surroundings. It can be placed wherever it fits in your room without sacrificing sound quality. Four aluminum leveling spikes are included to anchor the sub on carpeted floors, and 4 aluminum discs keep it from doing donuts on slippery floors. Like all NHT Classic speakers, the B-12d features NHT’s 10-coat piano gloss black finish. 

Inside - Start with 500 watts of really smart, efficient power. For the techies, we use a BASH PWM (Class D) amplifier with switching power supply. Unlike traditional amplifiers, the B-12d’s super-efficient design converts most of the juice coming from your AC 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, a sophisticated limiter, compressor and more. As a result the B-12d subwoofer goes lower, plays louder with better control than any 12" sub we've built.

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


Backside – Everything to integrate the B-12d with your stereo or surround sound system 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 a boundary control that electronically "moves" the subwoofer for best sound without actually moving it. The automatic power mode turns the B-12d on and off or select "Always On" mode for remote power switching. The B-12d 's smart, power supply adjusts to deliver full output anywhere in the world from 100v to 240v at 50 or 60Hz 

The Sound – Like all NHT subwoofers the B-12d is musical and natural on music and scary on movies. One B-12d in your system is serious. Two B-12d’s will deliver the ridiculous, even in larger rooms. If want a subwoofer to turbo-charge your system, blend perfectly into your system and provide smooth, seismic low end – drop and buy.

The Company - Let’s not forget that you’re buying an NHT subwoofer and that means all sorts of things like you care about getting the best speaker value for your money, that you care about quality craftsmanship and high-end performance. It also means you’re ready to join our family of fanatics who love music, movies and gear that produces them. Welcome to the club - tell a friend.

First thought visually and sonically, is WOW. Again, WOW! Now that I’m done with that, here’s my story. I originally purchased one B-10d and one B-12d for a 25’ x 27’ theater room. After speaking with Jeff Coats at NHT, I decided to use the B-10d in a Classic Zero setup (excellent idea!) and purchase another B-12d for my theater room. Jeff suggested that there is something magical about having dual NHT12’s in a theater setup. Jeff was right again! Oh my goodness, I was not prepared when I first turned my system on with NHT dual B-12d’s, again Wow. (My son says it sounds EPIC!) I have only heard one 12” woofer that even came close to sounding this good. The B-12d would literally blow that sub out of the water! This is a very musical and revealing subwoofer. I give yet another thumbs up to great new NHT product! If you have one of these or any other NHT product, help them out and submit a review. I know I always read reviews before purchasing and if you’re reading this, you do too! Spread the love and review your NHT products. We all want to have a good idea what we’re buying and want some assurance before our purchases…even if it is negative. I have been extremely pleased with everything I have purchased from NHT and the customer support they provide. So far, NHT gets an A+ from all my purchases and I’ll even go out on a limb to say they get an A+ from everything I have ever heard that has the label NHT on it. Thanks NHT for making a 12’ sub that exceeds expectations!

Very Pleased

I have a small room(24*20) with Paradigm Reference Studio 40 Speakers and a ParaSound 5250 Amp pushed by a new Denon reciever. I had a NHT Sub Two. The B-12d is crisp and strong. I am a lay person that can only tell you that I am very pleased with my new sub.It is worth the money. As you can tell, I do not normally write reviews, but I am very impressed the this Sub.

Great upgrade!

As a long time owner of the Sw2p, I was very excited to learn from a friend of mine that NHT was implementing a trade-in program. I was even more excited to learn that I was within driving distance to the showroom. I packed up the ol' sub and headed out to beautiful Benicia. I was quickly greeted by the head of security, "Sadie" who was very happy to see me! After talking at length with John about the history of the company I felt very comfortable in the showroom surrounded by all of the new speaker models. I gave up the 15 year old subwoofer that had served me so well and took home the shiny new 12 inch model. I was seriously shocked by the small form factor. My wife didn't even see it at first. From the beginning I knew this was a different sub. The boominess of the ported sub was gone and in it's place was a super musical low end with great accuracy to boot! I told John it took some getting used to, especially on music but it is the most natural sounding subwoofer I've heard in a long time. I was concerned about watching movies and losing some of the rumble of explosions and whatnot but that was not the case. I have to say, there is a bit of a break-in time (sorry, John), not much but once it went through the weekend something changed. It became fuller and meatier on the movie soundtracks. It was clear this speaker gives the best of both worlds. I really like it! Thanks John and NHT!

Unbelievable, Truly Outstanding Sub

Had NHT SW10II 10" and Polk PSW505 12" subs in my family room, with an otherwise all NHT system (M6 fronts, M5 center, iW3 surrounds and backs). Those two subs did a great job, especially with movie sound effects, but both were ported and definitely muddied music (especially when compared to the M-00/S-00 system I have hooked up to my computer). Again after much deliberation, decided to sell the Polk and drove down to Benicia to trade in the SW10II for something, maybe 1 B-12d, maybe 2 B-10d's. Was warmly greeted by two NHT mascots, a veteran and a rookie, who accompanied me my whole stay (cute dogs!). I've never met a president and VP of any company before, but Chris and John are two of the most unassuming, patient, down to earth, really nice guys you'll meet, presidents or not. I spent a lot of time listening to both new subs, mainly Lyle Lovett -- who John says is produced with NHT monitors . . . what a coincidence -- whose music I know by heart (played off of my iPhone), but also some rock, some electronic stuff, and some movies, to get the full breaadth of experience. John is right: the B-10d sounds amazing, but the B-12d is on an altogether different plane. It sounded deeper, fuller, better. I guess I am a basshead (as I said in another review), John said I cranked up the B-12d about 6dB too loud out of balance, but that's where I enjoyed listening to it. I picked up TWO B-12d's, 12 instead of 10 for the extra, effortless lower bass extension, two instead of one to reduce modes. John most certainly did not try to sell me two, he said on more than a few occasions I only needed one B-12d, but I was raised on the two-sub-better-than-one-religion. I'm glad I did: after setup, there are no dead spots, almost the entire room sounds like a sweet spot, and (for music), even though the subs are right next to me flanking the couch, the bassist is standing in the front of the room. And the sound: amazingly clear (clear? sub?), tight, responsive. Movie sound effects carry an incredible weight, having lost none of the power that I enjoyed from the ported subs, and music sounds INCREDIBLE, a thousand times better than with the previous subs. I'm incredibly pleased with these subs, as you can tell from the length of this review. But also genuinely pleased with the customer service at NHT, in this case delivered directly by the Pres and Vice Pres themselves. Oh, one final, really important detail: these things are tiny and look good. They passed the wife test: she loves the sound as much as she loves the black glossy, compact, unobstrusive look.
