BC Acoustique A-2 Brochure

The A2 is the second floorstanding speaker of the ACT line. It keeps the elegance of its little sister,
the A1, in a cabinet that is not much bigger in size.

It delivers a very dense and lively sound with a beautiful sound stage so characteristic of the ACT
line.

This 3 ways, 3 drivers loudspeaker offers excellent sensitivity. It is not too demanding and can
adapt to just about any kind of amplifier with high musicality.

The ACT line

With the ACT line, BC Acoustique wan ted to create s peakers with
a pure and sharp design using advanced technology.

The ACT speakers are the result of several years of research and
development. Looking at their fine design, i t is hard to realize th e
efforts that went in the ma king of the speakers and the level of
technology that can be found inside. The result is quite an
achievement.

Three specific technical aspects were particularly studied:

 Internal resonance modes
 Phasing
 Distortion level

These three aspects are ofte n weak points on speakers fo und on
the market, and this for a simple reason: the measuring devices
used in the world of electroacousti c do not offer the necessary
precision to clearly show some important phenomenon for which
the human hear is highly receptive.

With this in mind, BC Acoustique decided to develop its own set
of measurement devices and to adapt its manufacturing process
and testing facilities to these innovative techniques. These
devices give our engineers a higher precision in their work,
making this a significant progress in the field of electroacoustic.

These technical evoluti ons ma ke th e ACT line an accomplishment
with remarkable sound qualities. No place was left for luck.

But we always kept in mind that the final goal of all these
evolutions was to make sure that the listener would forget all the
technical aspects and enjoy the best of what music and sound
can offer. This is BC Acoustique’s philosophy.

The Tweeter

The A2 uses 3 drivers. For the treble BC Acoustique chose a BC100 horn
tweeter. A common model to all ACT speakers, this tweeter is the result
of an important collaboration with Fostex, one of the most prestigious
high end drivers’ manufacturer.

Compared to a classic dome tweeter, the BC100 brings a remarkable
definition of higher frequencies, an incredible clarity, efficiency and
good transiency.

Its frequency response chart is regular up to 50 kHz for an ideal
transcription of high definition sources (SACD or DVD-Audio) without
the inconveniences that can be found with super tweeters.

The BC100 can also reproduce all the dynamic that you can find in
music or movies without any loss or distortion.
