Now the reference speaker in France this product with its unique Bc100 horn tweeter design has taken the world market by surprise. In business for over 15 years Bc acoustique latest series the Act has spread through the European, Australian, Asian and now the North American market at a rapid pace and is not looking to steady down any time soon. Its popularity has come from its unique design that reproduces a very coherent sound. . The Bc100 horn tweeter puts out a very dynamic and lively sound, also the adjustable crossover allows it to adapt to varying room conditions. Bc acoustique has received many awards and great reviews across France and now more recently from across the globe.

	Bc acoustique Testing facilities BC Acoustique’s technical lead in research and development is based on a policy of intensive investments and on a partnership born 12 years ago with the largest acoustic laboratory in France (Laboratoire National d’Essais). Our engineers have at their disposal: a fully suspended 500m3 anechoic room, a semi-anechoic room, a reverb room,and 3 listening rooms. They have access to some of the most sophisticated testing facilities which allows them to precisely engineer their products.
	The Ideal Crossover The ACT loudspeakers use only low slope crossovers. This choice is the only one that can limit significantly the phase difference to preserve the cohesion of the sound image (see image on left). High slope crossovers (24dB or more) give a linear response curve but lose much quality in terms of time response of the loudspeaker. Our loudspeakers also have a possibility to change the level of high frequencies. With 5 different positions, it allows the listener to adjust the frequency balance depending on the acoustic of his listening room. The ACT crossovers use only high end components: TARA LABS™ cables, WBT™ connections, Litz coil, aluminium or tin polypropylene capacitors.
	revolutionary Cabinet Revolutionary speaker cabinet: To suppress stationary waves that can appear in loudspeakers, our engineers have developed specific resonators that absorb harmful frequencies. The benefit of this solution is an significant improvement in efficiency (absorption up to 40dB) and a maximum selectivity (about 1/48th of an octave). To absorb medium frequencies emitted by the rear side of the speakers, the ACT loudspeakers have quadratic diffusers that allow for an homogeneity of the energy inside the acoustic charge. The use of a new absorbing material (natural unicellular fiber) allows an important and homogenous damping. Before being processed (figure 1 on left) we can see that the frequencies corresponding to the resonance mode of the loudspeaker stay on top of the original signal and last for more than a second. After being processed (figure 2 on left) the interference frequencies have completely disappeared. The original signal is not disturbed. The diagram shows the energy of the signal (on a scale going from blue to red) according to its frequency (horizontal axis) and the time (vertical axis from 0 to 1 second bottom to top).
