2. The products

E 700 is a very compact 2-way bass reflex speaker with a 4" mid/woofer and a 1" soft dome

tweeter using our new DTT (Decoupled Tweeter Technology), see more details about DTT

and the drive units below.

The compact drivers improve the dynamics: As they weigh less they can move faster. Of

course under the precondition that they are equipped with

very powerful motors (magnet/voice coil) as is the case here.

The crossover frequency is 2,500 Hz.

Every diaphragm has a break up point and it is important

that the driver is used in a range where break ups are

controllable or do not appear. By choosing newly developed

drive units made from a special fibre glass and glue

compound, we have eliminated many of the known

challenges regarding break-ups in the diaphragm material.

For example the inevitable diaphragm break ups can be

controlled and distributed more evenly across the whole

diaphragm thereby avoiding uncontrolled colouring of the

sound at certain frequencies.

When used as a surround speaker in an E 7 solution, the E

700's voicing ensures that seamless timbre matching is

guaranteed when the sound pans across the room.

E 750 is a tall slim line 3-way speaker utilising a bass reflex system and a rear firing woofer.

The E 750 is equipped with the same 1" soft dome DTT tweeter as found in the E 700, and

the rest of the series for that matter. The bass/midrange

driver is a 5¼" and the rear firing woofer is a 5½".

The crossover frequencies are 150 Hz and 2,500 Hz.

The rear firing woofer on the E 750/E770 have been

specifically designed to deliver increased bass output but

with a very linear response, even when placed relatively

close to a wall. Furthermore this design will result in a

general level of 3-6 dB increased output (depending on the

distance from the front wall and the side walls) which means

that the drive unit can obtain the same relative volume level

but with less excursion, thereby minimising the overall

distortion.
