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.

Electronic overload protection
An electronic PTC resistor automatically limits power to the loudspeaker if it becomes overloaded.When the volume is turned down again, the resistor cools down and the sound is restored to its normal level.

Neodymium loudspeaker units
Neodymium is a powerful magnetic material – 10 times more powerful than a normal magnet. Therefore the magnet can be reduced in size, and be placed inside the voice coil of the loudspeaker unit, allowing the magnetic force to be concentrated around the voice coil – exactly where it is needed. Another benefit of the compact magnet is that is does not take up space inside the speaker cabinet, an especially important consideration with compact speakers

Fibre-glass cone midrange and woofer
The midrange and woofer drive units used in the E 6 series feature diaphragms made of a special fibre-glass/ glue compound.This material helps to control and distribute wave modes evenly, thereby ensuring minimal coloration and a very transparent midrange reproduction. The inverted dust cap together with the natural rubber surround linearises frequency response even further.

Gold plated binding posts
To ensure loss-less connection, the terminals are equipped with goldplated binding posts, accepting stripped wire as well as spades, pins etc.
