started with the debut of our highly acclaimed D 870 speaker.

The reason for choosing this conﬁ guration is that it grants you the best of two

worlds: The tweeter and mid-woofer reproduce the full frequency range, so, this 2

way system delivers the coherent, harmonious and smooth sound typical of tradi-

tional 2-way systems.

Then the additional woofer(s) blends in below 150Hz to add the extra cone area

and power handling needed to give full ﬁ delity in the low bass.

The dual bass reﬂ ex conﬁ guration means that the cabinet is divided into two cham-

bers – one housing the tweeter/mid-woofer and one the designated woofer(s).

This gives several advantages: First of all the sound pressure inside the cabinet from

the woofer does not inﬂ uence the mid-woofer and vice versa. This of course elimi-

nates colouration and so results in cleaner sound reproduction.

The two chambers are identically tuned but the bass cabinet features a larger port

(both in diameter and length) to effortlessly provide the considerable airﬂ ow re-

quired to reproduce deep bass.

The upper set of of the heavy-gauge, matt chromated bi-wiring/amping terminals

connect to the tweeter while the lower terminals connect to the mid-woofer and

woofer. This split was chosen in order to separate the heavy current ﬂ ow in the

midrange and bass from the more delicate signal going to the tweeter. The bi-wir-

ing/amping facility gives you lots of ﬂ exibility to tune the sound balance.

C 80 CEN

C 80 CEN centre channel speaker is a 2-way, bass-reﬂ ex system featuring two 6in

HCC woofers and a 1in DTT/WaveGuide tweeter.

The C 80 CEN can be placed on a speaker stand, book-shelf or on a TV (in the sup-

plied rubber cradle), allowing the arc-shaped speaker to be angled towards the lis-

tening position and, just as importantly, ensuring stable placement of the speaker.

The C 80 CEN is of course magnetically shielded to enable placement in the vicinity

of a normal CRT type TV.

C 80 SUR

The C 80 SUR dipolar surround speaker is deliberately designed to deliver a diffuse

sound, giving you the feeling of being enveloped in sound. Dipolar loudspeakers

usually suffer, however, from a lack of efﬁ ciency in the deep bass area. To compen-

sate for this fact the C 80 SUR is equipped with a special Jamo feature called XBR

(eXtended Bass Response). XBR inverts the phase on one of the two woofers so that

at frequencies below 250Hz it functions according to the bipolar principle.

Using a combination of di- and bi-polar principles not only ensures ultimate diffuse
