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 2nd order 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.
