Duntech Regent/Black Knight



The Regent uses a five driver system which is symmetrically arranged on a vertical axis to ensure time alignment.
The woofers have a magnesium, diecast chassis. A vented, long throw magnet system reduces air movement noise. These low distortion drivers employ hexacoil technology for very high power handling.

The mid-range drivers have a large voice coil diameter on an aluminium former, with a wide dispersion pattern and excellent phase characteristics.


 

The tweeter is positioned 950mm (37") from the base of the cabinet, about ear level when a listener is seated. The use of ferrofluid dissipates heat very efficiently and dampens driver resonance. Soft rolloff suspension prevents phase anomalies in the upper frequency range.

The cabinet size is optimum for this combination of drivers and has the ability to reproduce very low frequencies at realistic sound pressure levels.

An infinite baffle system is used, in preference to a vented enclosure which very often produces a woolly or ill-defined sound.

The mid-range drivers are mounted in their own sealed enclosure to prevent interaction with the woofers. The tweeter is a sealed unit.



Foam is placed in the cabinet to reduce panel vibration and permit optimum performance of the drivers. The density, shape and position of the foam is matched to the specific requirements of the drivers.

The first order type crossover employs hard wire point to point construction with aircore inductors. Polypropylene capacitors are used for their stability, high voltage, low loss and low inductance. Resistors are high powered ceramic type.

The input terminals are gold plated for reliable connection and to eliminate corrosion.

The system accommodates bi-wiring and passive bi-amplification.

The loudspeakers are covered with acoustically transparent black cloth which has minimal effect on sound reproduction.




 
   
     
                         

The Regent and Baron cabinets, and the stands for the Viscount and Esquire models, come with hardened steel spikes which may be used to minimise motion and increase stability.
