MPD (Midrange Phase Diffusion)
This unique technology incorporates a midrange unit in opposite phase with a two way system on the other side of the surround loudspeaker. This provides the diffuse surround reproduction typical of dipole loudspeakers, yet still gives the full bass reproduction that such designs have traditionally lacked. Mineral/paper cone Due to its light weight, paper has always been an excellent material for loudspeaker cones. To obtain a stiff cone with optimal internal damping, the paper is reinforced with mineral fibres. The increased rigidity makes flat, exponential cone design possible, allowing the woofer to cover a wide frequency range and thus enable a very smooth transition to the tweeter. The result is a very precise quality of sound reproduction.

DTT (Decoupled Tweeter Technology)
By decoupling the tweeter from the rest of the loudspeaker, vibrations transmitted from the front baffle to the tweeter are reduced by more than 20 dB resulting in an uncommonly detailed and realistic reproduction of high frequencies.

EPDM (Ethylene Propylene Diene Monomer)
Firstly the tweeter is decoupled from the aluminium front baffle using a special rubber compound called EPDM (Ethylene Propylene Diene Monomer) which has extremely good acoustical properties.

Wooden Front Baffle
Secondly the aluminium front baffle is not just screwed onto the wooden front baffle but mounted using natural rubber rawlplugs which further prevents vibrations being transmitted.
