The story
Byrne primarily handled sales and marketing, while Kantor (introduced to Byrne by Michael Riggs, then at High Fidelity magazine) was responsible for design and engineering.
In 1987, NHT shipped its first product, the Model 1 loudspeaker.
In 2004, NHT unveiled its XdS line of speakers and supporting processors. XdS speakers are DSP corrected active speakers with digital amplifiers. The XdS line has since been discontinued.
In 2007, NHT introduced the Classic Three Bookshelf Speaker, which received critical acclaim. Theo Nicolakis of Audioholics wrote that "what the Classic Threes do have is a total sonic package that’s nothing short of amazing".
In 2016, NHT released its C Series line of speakers to replace the Classic Series. Secrets of Home Theater Hi-Fi praised the C 3 Bookshelf, saying the speakers "look great, sound great, and measure superbly. And in true NHT tradition, they accomplish all that at a very reasonable price."
