The NHT XD System is an active speaker system with DSP based crossovers and inherent phase/time and room correction.
The XD System is designed from the ground up to incorporate DEQX Calibration. This is a DSP technology for loudspeaker correction and incorporates very steep linear phase digital crossovers.
The amplifier section of the NHT XdA contains four PowerPhysics One-Cycle Sound™ amplifiers that supply high-efficiency bi-amplification of stereo channels and two balanced,line-level output channels for the woofer(s). PowerPhysics™ proprietary Class D amplifier is compact and highly efficient, generating the bare minimum of heat, allowing NHT to put all electronics into a single chassis measuring 2.6″H x 17″W.
The diminutive (10.25″H x 6.5″W x 8.5″D) NHT XdS satellite speaker features a two-way acoustic suspension design that houses an ultra-low distortion 5.25″ midrange and 1″ neodymium tweeter. A massive heat sink is attached to the rear of the tweeter to provide substantial power handling while the cabinet baffle itself is molded from a dense, sonically neutral composite material designed for far-reaching sound dispersion. Each satellite is bi-amplified, with the midrange and tweeter each powered by an individual amplifier.
Rounding out the NHT Xd system is the NHT XdW powered bass module, comprised of two active, opposed 10-inch drivers and a PowerPhysics 500W amplifier. Unlike other powered woofers, the XdW features only three controls – volume trim, balanced input and voltage selection. (Crossover functions such as frequency response, phase, crossover point and time-domain filtering are managed by the DEQX processor in the XdA.)
DEQX Calibration™: Why and what for?
In short, DEQX Calibration measures loudspeaker and room acoustics using the company’s unique methodology, with special filters that simultaneously correct all frequencies in time as well as phase and frequency response to optimize system performance. As a result, sound is dispersed across a much wider stage without being tied down to a narrow sweet spot. The mechanical errors inherent in all loudspeaker drivers are largely eliminated, providing a strikingly natural sound. Additionally, imaging is articulate and defined while distortion is reduced to previously unattainable low levels that are usually associated with electronics components, not speakers.
This high end speaker system will perform superbly in all environments large and small.
Very good condition.

I have used this system in my own home theatre for the past 7 years and it is now time to move on.
Obviously this is a large system, and will suit medium to large rooms.
Bag End 18″ Sub Woofers (1 pair) With ELF 1 Integrater & 600wpc BG Radia BGX A2 Amp
These Sub Woofers will do justice to any system. They have been my favourites until I auditioned and subsequently sold a pair of Velodyne DD15 Plus Sub Woofers which have now become my reference.

This is Usher’s flagship. Each speaker comprises of two diamond tweeters, one 4″ quality high compression maple driver horn and two 15″ woofers.
The sound from this loudspeaker system is akin to a live performance with no compression which is normally associated with most loudspeakers.
It is suitable to medium to large rooms and one can literally transform one’s listening room to a concert hall. Sound quality wise it’s presentation is similar to a live performance.
As it has two diamond tweeters, it is not rolled off like other electrostatic/horn speakers and it’s top end frequency extends to 40 khz. The bass section extends to 22 hz thanks to it’s twin 15″ bass drivers. The midrange magic and immediacy is produced by it’s compression horn. It is very efficient and is easily driver by moderate amplification.
Each speaker weighs 236 kgs. However each speaker is broken down into four modules for easy transportation.
If you have the space and wish to be treated to a concert hall experience every night, this is your opportunity to purchase a very rare masterpiece at a fraction of it’s original price.
Sensitivity 94db, 1 watt/1 metre
Impedience 4 ohms
Freq response 22 hz-40khz (-3db)
Weight 236 kg each (including bass)
71 cm wide x 78 cm depth x 178.5 cm high.
