Wall mount:

The rear wall "amplifies" low frequencies and the floor

actually gives a dip in approximately the same range due

to the first floor reflection reaching the ear in opposite

phase with the direct sound from the speaker.

The speaker can be used as full range. In this case the

subwoofer should be adjusted to blend in seamlessly in

order to suit the room and personal preferences. However,

D 400 is intended for crossover at 80 or 100 Hz – again

depending on the room.

The resonance frequency of the tweeter is as low as 600 Hz. The x-over to the mid-woofer

is set at 1.7kHz but due to the excellent low frequency extension we use a low Q 2

filter to roll it off downwards. So, actually it plays down to 1 kHz. Thereby, we secured a

seamless integration between the drivers, and avoided potential phase errors caused by

high order filtering.

D 430

D 430 is a 2 way bass reflex system featuring a 6½" woofer and a 1" DCD

tweeter.

This compact bookshelf speaker can be placed on a bookshelf – or on the

designated D 4FS stand – providing a very stable placing at the correct

listening height.

The D 4FS can be placed either by using the adjustable

spikes securing a good mechanical coupling to the floor

independent of floor materials or, if you prefer to

decouple it from the floor, by using the enclosed rubber

absorbers. The design and choice of material for the

rubber absorbers (PUR 80 Shore A) was made to match

exactly the D 4 speakers.

The D 430/D 450/D 4CEN all feature Jamos Convex Tapered Vent. This high

flow bass reflex port design ensures less turbulence and allows 5 dB higher SPL before port

noise occurs – which means that in practical life, port noise is eliminated!

The D 430 features gold plated bi-wiring/amping terminals – giving you all possibilities of

"fine-tuning" the sound by using cables that suit exactly your equipment, your room and

personal preferences.
