Advance Acoustic
Advance acoustic was formed after the decision was made in Toulouse France, to create a new French brand with an idea which was both simple and audacious: to design audio equipment, reasonably priced but with faultless musical quality. Speakers were the first products off the production line, with 5 models becoming available.
These were an instant success and received high praise from many French magazines. In 2002, Advance Acoustic added electronics to their product catalogue, while keeping the same simple philosophy, reasonably priced without compromising on sound quality.

Advance Paris company, designing and developing Advance Acoustic products, decided to launch its Hi End range of products, under the Advance Paris brand

X-L500 loudspeakers are designed by Advance Paris’ acoustical engineers. Their design, based solely on acoustic principles, allows it obtain pure, modern and elegant curves.
The X-L500 loudspeakers provide a perfect reproduction of instruments and voices. Their harmonic richness and rhymic speed, give a perfect preception of presence and realism. These parameters, are only some of the exceptional qualities of the X-L500 loudspeakers.

The MDF cabinet is built in 3 independent boxes, with walls reaching 4 cm in thickness. The boxes are linked by separations with decoupling, ensuring the complete control of vibrations. The location of the drivers were calculated in order to achieve the best phasing.

We designed the X-L500’s drivers. These drivers combine excellent performance which is rarely achieved.
The Woofer and mid-range are built with a cellulose pulp membrane. Rigid and lighter, these are associated with very powerful magnetic circuits (the woofer 12“ (307mm) has a voice coil : inner diameter is 49.55 mm, magnet spec : 170*85*25 mm, magnet field is 1.8-2.0 T).

The sound transparency and the absence of directivity make the mid-range driver, one of the best transducers at this time to reproduce music with realism and precision.

The ribbon tweeter reproduces high frequencies with low distortion. Moreover, its frequency response makes it ideal for the mid-range driver, coupling sweetness and dynamic without any form of aggressiveness.

The crossover elaborated with great care, divides into an ideal way the different frequencies, found in the musical message, towards all the drivers. Due to its perfect control of phases, the different drivers reproduce the music with consistency and coherence.

Moreover, with a sensitivity of 94 dB, and an impedance of 8 Ω, the X-L500 loudspeaker can drive amplifiers from 30 to 300 W.
Designing the
X-L500 loudspeaker, our aim was to achieve exceptional loudspeakers, without compromise, and working on several parameters often neglected or contradictory.
