General description

With the Jamo D 4 Concept the goal was to create “the link” between high-end hifi and - surround sound and at the same time focussing on versatility – or flexibility – in system configuration and placement.

So, what are the “problem areas” in doing that?

Well, it could be extended treble response “demanded “ by the new multi-channel sound formats, it could be the extended bass response “demanded” more and more by the extreme movie soundtracks – and at the same time maintaining musical fidelity, absolute coherence, perfect imaging etc. And last but not least, products that you can actually live with in your home . . .

This of course was a huge challenge for the development team; acoustics- electronics- and mechanical engineers as well as our design team from Carl Bro.

The code word in the whole process was: Form follows function

The result of this can e.g. be seen in the slim line cabinets without any edges to cause diffraction, the double curved front baffle which is not only a very rigid and resonance dead construction but also improves time alignment of the tweeter.

Of course the task also demanded choice of very high quality materials and development of completely new and very powerful driver units.

The sound reproduction of the D 4 is very detailed, clear and open in the

entire spectra, with a large listening window making it easy to locate instruments, vocals and subtle details when listening to music or experiencing a movie.

The Products

D 400

D 400 is a closed 2 way system featuring a 5¼” woofer and a 1” DCD tweeter (see more details about the driver units later in this document).

This is probably the most compact high-end hifi speaker ever made - just 11 cm/41/3” deep.

And not only is this a true high end performer it is also a very versatile speaker that can be used for 2 ch. hifi, as front, centre and surround speaker in a surround set-up with identical main speakers and as surround speaker in a set-up with the D 430 and D 450.

The D 400 is optimised for wall mounting –which gives several advantages.

When wall mounted more parameters are “controlled” than with a free standing position: As there is no distance from the speaker to the rear wall, we know that low frequencies are acoustically amplified and how much. We recommend placing the speaker 1 metre above the floor. The most common listening distance is 2 – 4 m / 6 – 12 ft., so we can quite accurately predict the contribution from floor reflections too.
