At first impression this could sound really impressive,
but especially when listening to music the sound can
be "boomy" and rather annoying.
The Boundary Gain Compensation starts at 55 Hz -3dB
and drops to –10 dB at 20 Hz.
For users of THX decoders without Boundary Gain
Compensation, the D 7SUB has a quite unique feature:
Boundary Gain Compensation is built into the D 7SUB
on a separate input, thus granting optimum benefit
from the D 7 System with existing equipment.
The level control is placed on top of the D 7SUB
elegantly integrated in the design. When it is turned to
the point of THX reference level a LED lights up –
indicating the THX specified input sensitivity.
Drivers
Tweeter
The tweeter was chosen for 3 main reasons:
1. Extremely low distortion
2. Totally freedom of accentuation of "s" sounds.
3. The low range extension
