Each monitor has three channels of Ultra Efficient “Class D” amplification, one for each of the frequency bands and uses a Linear Power supply mounted on a large aluminium heat sink. The amps provide a clean powerful signal to get the best from the drivers.
The SP25MA Crossover is an active, three way controller with a balanced analogue input, giving ample headroom and superb dynamic response
UHVC Drivers - Under Hung Voice Coil Drivers:
This over engineered method of voice coil and motor assembly used in our low frequency and mid range drivers involves the use of an extra deep magnet gap and an unusually short voice coil winding depth. This ensures that, as the cone moves back wards and forwards the voice coil is always contained within the same amount of magnetic flux. This enables extra long cone excursion and reduces harmonic distortion to a minimum.
CLD Cabinets - Constrained Layer Damped Cabinets:
Large flat Enclosure walls can , if not controlled properly, vibrate and add unwanted colouring to the speakers overall sound. We make our cabinets out of the highest quality MDF which is then lined with ceramic plates which are fixed to the walls using a flexible adhesive. Because these two materials have very different resonant behaviours the effectively cancel each other out leaving an acoustically inert material.
Anadised Aluminium Cones are used for the FL Drivers to give pure piston performance throughout the frequency range that we use in these monitors. The aluminiu also provides heat sinking to keep the voive coild cool. This increases the power handling and reduces the thermal compression usually associated with other materials.
