General description 

 

With the 

Jamo

 

D 7 System

, the goal was to 

create a THX certified system, where the famous 
qualities from our two predecessors are kept i.e. a 

wide and high listening window, design and 

compact size, but with an even more dynamic, 

open and detailed sound reproduction. 

 
This was done through the choice of very high 

quality in materials and development of 

completely new and very powerful driver units. 

 
The sound reproduction of the 

D 7 System

 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. 

 

With – 6dB points at 20Hz and 40.000Hz, compatibility with multi channel audio is obvious. 

 
The 

D 7 System

 fulfils the new THX Ultra2 standard and is at the same time a true 

high-

end hi-fi system

. And probably being the most compact THX Ultra2 certified system in the 

market enables most people to integrate the system into a “normal” home interior. 

 
A complete 7.1 set up requires 5 x 

D 7LCRs

 (3 pcs. as front speakers and 2 pcs. as surround 

back speakers) and 2 x 

D 7SURs

 as surround speakers. Finally 2 x 

D 7SUBs

 complete the 

system.  However, as the THX certification applies to a 3000 cu. ft. /110 cu. m room which 

approximately refers to 400 sq. ft. /40 sq. m., one subwoofer will be more than sufficient for 

rooms smaller than this. This is in fact one of the reasons why Jamo has chosen to make a 

more compact subwoofer – giving the consumer freedom of choice depending on his 
room size and personal preferences – we call this “Individual Sound Solutions”. 

Also, using two “small” subs instead of one “big” sub, makes it easier to obtain a smooth 

power response throughout a large room. 

 
In some aspects, the 

THX Ultra2

 requirements are not as restrictive as the “old” THX Ultra 

as a wider vertical dispersion from the front speakers is allowed. 

We welcome this, as it fits well into our philosophy about not having a narrow vertical 

dispersion. In our previous THX systems we have always kept this focusing to a minimum. 

 
In the development of the 

D 7LCR

, great efforts have been put in getting as wide vertical 

dispersion as possible. 
Our philosophy is lived out through the 

D 7LCR

 - you will simply experience a large open 

listening window, regardless of the listening height. 

 
All seven main speakers in the 

D 7

 

System

 are designed for wall mounting. But as a new 

option, the 

D 7LCR  

is also designed for free standing – on an extremely sturdy dedicated 

floor stand.  

 

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 the room amplifies low 
frequencies and how much. We recommend placing the speaker 1 metre above the floor.
