Sub6
Professional analog
monitoring subwoofer
The Sub6 is an active subwoofer (1 x 350W RMS built-in amplifier -
BASH technology) for professional monitoring systems. The driver is
an 11" Focal with a "W" sandwich composite cone loaded by a large
section laminar port. It can be used both as LFE channel in a surround
system or as a bass or sub-bass complement in a stereo system (2.1
or 2.2). The Sub6 was designed to permit optimum acoustic coupling
with professional monitoring speakers. Therefore, it includes all the
features to achieve this task, such as stereo high pass filter (75 or
100Hz) for the left and right satellites, low pass filter (adjustable)
with mono summation, phase inverter, phase fine tuning, mute
switch, 2.1 bypass with a footswitch remote control (not included), as
well as a wiring panel rich in possibilities
.
• The “W” cone
Focal has been developing the technologies of composite sandwich
cones for more than 15 years. The "W" process (Glass/Foam/Glass),
used on the SM11, SM8 and SM6 lines, provides a true optimiza-a true optimiza-
tion of the frequency response by fine tuning of mass, rigidity and
damping parameters.
The balance between these 3 fundamental
and often contradictory parameters is at the base of the outstanding
sound neutrality of our speakers.
The 10
5/8
"(27cm) Focal speaker is equipped with a high excursion
system to enable accurate and extended reproduction in the bass/
infra bass register. The 2
5/8
" (66mm) diameter and 1
1/4
" (32mm)
height voice coil ensures a perfect mechanical coupling and a
total control of the driver even at high sound level. The magnetic
construction made of double ferrite and large field and back plates
offers high symmetrical magnetic field to keep dynamics even at
very low frequency.

A custom designed amplication stage
Designing an amp to be integrated inside a speaker requires a very
different set of rules than for a traditional amp. Speaker size and
cooling concerns are often in contradiction with the high quality and
high power requirements of a sonically transparent speaker.
Our engineers used the BASH® technology to develop the bass/me-
dium amplification circuit for the SM6 professional line of speakers.
This was the only way to exploit the best of class AB style circuits
(for exceptional quality) with a class D type yield, which is crucial
when housing a 150W RMS circuit in such a small space (300W RMS
for the Twin6 Be and 350W RMS for the Sub6).
