“Blue Moon Audio Technology LS 3 speaker system is seriously pushing

the bar of ultimate sound reproduction, acting on a very different plane of reality. “

The LS 3 (Line Source 3) are top-level loudspeakers, unique in their project and strongly innovative.
They use the Array configuration, they are four-way loudspeakers with a super-tweeter with some peculiar and special characteristics.
As well as using AMT Tweeters , they have cones for others ways.

All these drivers work in free air with dipole emission in order to assure a truthful reconstruction of the acoustic scene.

A tower of six closed-box woofers for each channel deals with low range which is independently amplified .

Each loudspeaker can adjust the inclination of the two lateral panels in a range included between 0 and 30 degrees, so that the best interfacing loudspeakers/environment can be provided.






The LS3 are equipped with dedicated active crossovers, to achieve maximum audio quality.

With the LS 3 by BLUE MOON Audio Technology the reproduction of the sound message is as close to the real event as possible, both in terms of realism of the scene reconstruction and in terms of the most important sonic parameters such as timbre, transparency and dynamics. All this is obtained without that sonic gigantism typical of this kind of systems.

The LS 3 are becoming world-class Hi Dream systems with full rights.
