Our manufacturing starts right from the design and conception of the loudspeaker. We leave nothing to chance that could potentially damage the sonic quality of the loudspeaker itself, and this is why we take such care in our manufacturing process, so that you the listener will never be compromised. |

A view of the factory floor. This is where the components for the cabinets are machined. We want to emphasize this is a factory, not a warehouse or assembly shop.
A lot of the work is done by hand.
For accuracy we use the CNC (pictured at the back) to router out the components.

All of that for this. Consider how powerful vibrations are. A woofer can move 3 mm back and forth 2000 times per second (2 KHz). Imagine your car motor doing this cycle with loose engine mounts. Most of the energy will be lost on the mounts, with very little transferred to the tyres. An 8 inch woofer has a surface area of 220 cm2. An average excursion is 3mm, so air displacement per cycle will be 66 milliliters. A cabinet with side walls measuring 90 x 36 cm, will only have to flex a tenth of a millimeters to produce the same sound pressure. Half that movement is only three decibels less, a quarter of that (now just a bit more than the thickness of hair) is only 6 decibels less. Now consider that there are front, back, top and bottom panels as well.
This means transient signals such as plucking a string are significantly muted. Natural decays are virtually lost. The added resonance of the cabinet disguises harmonics.
This is referred to as noise level. Amplifiers are tested for this. However this is seldom mentioned with loudspeakers, the only component in your system that converts electrical energy to mechanical energy.
|
This is why we place so much emphasis on the cabinet.

Our construction is remarkable, but it doesn’t stop there. We use unbalanced veneer on some panels, and use a double or triple ply veneer on others.
Although wood veneer is usually 0.7 mm thick, it is incredibly strong. A single layer applied to one side of a 50 mm board will warp the board by 5 mm within a week.
This approach of using veneer for acoustic outcome as well as aesthetic is unique.
Although the HT-M’s are the lightest of our floor standing speakers, they are subject to a pressure of 1.5 tones in this process.
Imagine a 6 tone truck being held off the ground with a speaker under each wheel. Even more impressive when you consider that our small surround speakers (HT-R) can handle the same pressure. |

Take a close look at our cross-over filter boards. There are no ferrite core inductors. The filter capacitors are of our own design. The boards are completely hard wired.
To ensure that the EMF between components remains constant from board to board, we engrave the mounting positions for the components. The boards themselves are made from 18 mm MDF. With the exception of the HT range, the boards are mounted in an isolated compartment with in the main cabinet. |

Yes, we do use drivers with huge magnets, boasting the latest technology.
We source our drivers from Denmark, and ensure that they are equal and matched to the cabinets.
The cost of a good cabinet far exceeds the cost of a new type magnet, or what ever seems to be the latest rave at the patents office. |

The final phase is to ensure that each assembled speaker is tested and compared against our reference specification.
Once it passes that test, the pairs are tested for both SPL and Impedance matching. The serial number is issued, and the plots stored.
We cannot patent dedication and commitment. But you can hear it.
