The cone excursion from all bass systems is measured through the light sensor and displayed on the control computer via the LAN network. Thus, the system can be driven to their limits without exceeding the maximum deflection of the membranes.
The pyramid tip of the compression chamber is illuminated by the light reflections from the horn surfaces. The light collects in the centre of the bass horn. From there, send 6 pcs. JBL 15 inch speakers your sound energy toward the light. The horn areas that concentrate the light so beautiful, direct the sound in the reverse direction, with the highest precision.
With horn, the sound pressure is summarised in one direction and bundled and thus greatly increased. It can be assumed that about 10 dB more sound pressure, so it must only 1.10 the performance !!!!!!!
This consolidation creates a beam carrying sound very far, like the water splashing garden. However, this beam is responsive to pressure changes of the speaker more accurately. Through this connection, the immense increase in the precision of the sound playback with horns comes alive.
Due to the large radiating surface, it corresponds to the membrane surface of 62 pcs.
