Shinjitsu Audio HON Dual Driver Speaker - Heil AMT


These are our HON speakers utilizing a proven and well reviewed Japanese design back loaded horn and Heil Air motion Transformer enhanced to smooth and extend the critical high frequencies and midrange musical overtones.

All True Baltic Birch Laminate Labyrinth construction with 1/4 inch thick solid Monkey Pod Wood front panel. Neutral Danish Oil finish hand buffed.


The low frequency driver is our Swan designed wide range drive unit with precision non resonant cone coating to reduce ringing and lower Fs with a wide operating range from 36 Hz to 2 kHz with an extremely broad directivity pattern. Advanced low-distortion motor design. Long-stroke suspension with arrestor and progressive-rate spider. Low-profile surface-mount reinforced steel basket. Crossed over second order design over at 2 kHz to avoid beaming.


The high frequency driver is the critically acclaimed original Heil Air Motion Transformer widely recognized as the world’s best midrange tweeter. The Heil diaphragm, made of soft, quiet mylar to reduce background noise, is bonded with conductive aluminum strips. It is the equivalent in surface area to a conventional cone eight inches in surface area. The low mass diaphragm is suspended in a massive magnet structure concentrating an intense magnetic field around the diaphragm. The ESS Heil Air Motion Transformer (AMT) is recognized by the audio industry as the most significant loudspeaker breakthrough of the last half-century. Shinjitsu Audio sources each Heil Transformer directly from ESS with a certificate of authenticity provided. 


The laser cut solid maple back plate is terminated with solid copper heavy duty speaker terminals and a unique attenuation network. The attenuation resistors provided allow for infinite adjustment of midrange crossover point and high frequency SPL and help to compensate for room response and age related high frequency hearing loss. Tailor the highs to your desires.


Versatility in placement allows for tilted back floor standing, stand mounted or shelf mounted placement. Designed for deep bass in any configuration these speakers are tested to energize rooms up to 1000 square feet with punchy deep bass and are perfect for small apartments as well. They can reach crescendos of live music at 100dB with just 15 watts of input.


These speakers are designed for high sensitivity and can operate with as little as 8 watts and are rated to produce up to 100 dB of sound pressure level in an average sized room. Comfortable with chamber music to all out rock and roll these speakers provide a wide gamut of musical tastes.

  • Optional stands raise the speaker to 36 inches which is the average ear height when seated
  • Weight: 47 Lbs.
  • Sensitivity: 87dB to 90 dB depending on high frequency attenuation selected
  • Maximum Power Swan low range driver 50 steady and 100 watts continous
  • Maximum Power Heil AMT 40 watts steady and 100 watts continous
  • Maximum combined SPL 100 watts which is equal to: 100 dBA tractor, helicopter or racing car 10 meters from the stage at a loud rock concert.



The most elegant way to enhance bass response is the backloaded horn speaker.

  • Designed to collect the back wave (which in normal speakers is wasted or absorbed) the speaker driver amplifies the bass via a properly designed labyrinth enclosure which exits the horn located on the back of the speaker enclosure. This clever design enhances bass more efficiently and accurately than bass-reflex and sealed enclosure types.
  • Back loaded horn type enclosures make the most efficient use of such back sound waves. Back-loaded horn system enclosures work in such a manner that, as bass comes out of a horn mounted on the back of a driver, the rest of sound spectrum, e.g. mid- and high-frequency ranges, is radiated directly from the driver.
  • Speakers employing back loaded horns are highly efficient by actively utilizing sound output from the bass driver and respond well to the subtlest components of music signals. Improved transient response, speed and effortless sound quality are some of the hallmarks of this type of driver arrangement.
