The most common listening distance is 2 – 4 metres, so we can quite accurately predict the 

contribution from floor reflections too.  
 

Wall mount: 

The rear wall “amplifies” low frequencies and the floor 

actually gives a dip in approximately the same range. 

With a carefully calculated compensation in the crossover 
we end up with a linear frequency response, down to 80 Hz 

(-3dB). 

 

 

 
 

 
With the speaker placed “freely” on the 

D 7FS

 (D 7 Floor Stand) there is little or no 

influence from the wall behind the speaker, it then acts as any other speaker placed on a 

stand. – i.e. with “normal unpredictable” room influence. 
 

The two placement options require separate input terminals for wall mounting and for free 

standing. 

 
As earlier indicated the design idea of the 

D 7 System

 is kept in the same way as the D 6 

system, with three identical speakers as front/centre. Due to the flat planar design the 3 

7LCR

s can be mounted in a horizontal line which prevents the sound image from 

“jumping up and down” when the sound pans between the speakers. The sound image 

also benefits from the 3 identical front/centre speakers, as there is no difference in timbre 

and dispersion pattern. 
 

The aesthetic impression from the system is quite unique with the three elegant identical 

speakers at the front. The black fabric is shaped with an arc shape over the “midrange/ 

tweeter array” in the centre and with a thin vertical aluminium line on each side of the arc. 

On the top of the front frame is an exclusive oval aluminium badge with the Jamo - and 
THX Ultra2 logo.  

The cabinets come in Stone Grey. 
The surround speakers 

D 7SUR 

and the subwoofer 

D 7SUB 

match the design of 

D 7LCR
