1. General description 
 
The goal with our new E 7 series loudspeakers has been to bring audiophile quality 
loudspeaker technology to the mass market. Furthermore our requirement from the start 
has been that this new series should perform equally well with music as movies and have 
the eye pleasing aesthetics that allow most people to integrate these loudspeakers in their 
everyday living rooms without sacrificing their interior decor. A task that proved to require 
new and ingenious solutions as well as ground breaking technology from our EISA award 
winning D 7 series. 
 
These are loudspeakers designed by engineers with a 
passion for music in all its forms. Anybody who listens to 
these designs will hear that. We wanted this new range to 
exceed all sonic expectations in the class… we think that’s 
exactly what it does. 
 
One of the biggest challenges when designing speakers is 
preventing unwanted cabinet vibrations from clouding or 
colouring the sound. High frequencies are particularly 
susceptible so we came up with the first ingenious 
solution… Decoupled Tweeter Technology (DTT)
Exploded view of the 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. 
 
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. 
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.

The loudspeaker cabinets themselves are constructed from solid MDF and the front baffle 
is angled by 2 degrees in order to further enhance the rigidity of the cabinets. The two 
floorstanding models in the range also have internal bracings adding further to the 
structural stiffness of the whole construction. Please refer to section 4 for more information 
about the cabinets.
