The low crossover frequency of the woofer (150 Hz) also make sure that the drive unit

performs in the frequency range were it is designed to perform best, delivering a deep

powerful bass equally at home with music and movies.

2.3 E 770

The range-topping floorstanding model in the E 7 series is the E 770, similar in proportion

and driver complement to the E 750 but physically larger at nearly 1m high and even

better endowed in the driver

department. The same 1" DTT

tweeter is used, naturally, but

here it's partnered with a

front facing 6½" mid/bass

unit and a ported 6½" woofer.

The crossover frequencies are

similar as with the E 750 150

Hz and 2,500 Hz.

By utilising a rear firing

woofer on the E 750/E 770 the

in room bass response is also

easier to control as the

natural

quarter

frequency

cancellation

minimised.

This model offers a low frequency response that reaches down to 35 Hz, allied to 90 dB

sensitivity.

Vocal clarity is all important in any centre-channel loudspeaker so using the Decoupled

Tweeter Technology in the E 7CEN was the natural step. Here for timbral accuracy, it's

partnered by a pair of the same 4" mid/bass drivers you'll find in the E 700 and augmented

with a flowed port at the rear

The crossover frequency is 2,500 Hz.

With a height of just over 14 cm the E 7CEN is extremely compact and thereby easy to

place in the listening room.
