EL 210 is a three-way speaker. Its 21 cm- diameter boomer-medium can reproduce deep and striking bass sounds. The medium speaker ensures the natural and realistic reproduction of voices, whereas the tweeter ensures a subtle and detailed reproduction of trebles, exempt from any harshness
1) The cabinet of the speakers Advance Acoustic is built of medium, reinforcements and internal partitions insure perfect rigidity to avoid the development of vibrations.
2) The energy reflected on the internal walls of the speaker creates stationary waves. To eliminate these interferences causing a colored listening, we developed the BSW system (Breaking Stationary Wave). This system is composed of a rubber ovum, semi-reverberating, whose faint oscillations are caused by the variations of internal pressure in the loudspeaker. The oscillations of the rubber ovum do not generate noise, but eliminate the stationary waves completely.
3) After numerous tests, we noticed that the positioning of boomers on the lateral, internal sides of the speakers, improved significantly the three-dimensional broadcasting of music. This technology introduces the double advantage to be able to use a boomer of greater diameter, more efficient in basses, while keeping a slender aesthetic line.
4) We develop our drivers in order to obtain the features and performance desired. The membranes, in pulp of cellulose, guarantee a neutral musical restitution, the pure copper moving coils are fixed on a capton support.
5) The final performance of a speaker will be determined by the filter! Advance Acoustic developed a precise and rigorous filtering technique. The choice of the best components, air selfs, polypropylene capacitors, precision ceramic resistors contribute considerably to musical performances.
