The G50-A1 is a multiple-driver, curvilinear line array housed in one compact box. It should be noted that common Line Arrays have just one optimum arrangement, depending on the relation between the curvature angle of each module and the shape of the waves that emerge from the HF areas.
Since every line array module is identical, optimum coupling can be achieved only by radial shaped configurations. Real flat wave generators perform best into zero degrees position and phase cancellation effects appear into one degree position, increasing by augmenting the curvature angle. The total absence of gaps between the multiple phase plugs gives consistent advantages in the high frequency domain (JAES V52-5 pg. 467, Mark Ureda - Northrop Grumman).
The G50-A1 has multiple phase plugs arranged as a virtual point source, where the vertex is some meters away from the speaker. Every phase plug generates a slight phase shift which is indispensable for minimum vertical coverage. Every phase plug is coupled directly to the next one, thus reducing phase shifts virtually to zero.
Two systems together will serve as a 12 unit line array system that always radiates in the best physical position desirable.
Close attention has been dedicated to the physical position of each radiating area. Optimal horizontal radiation behaviour has been achieved by placing the MF speakers as close as possible to the HF output area. Interference between MF drivers and HF drivers has been reduced to negligible levels.
Revised in its structural design and his technical detail the G50-A1 is one of the most complex and faithful speakers on the professional loudspeaker market. Even if the unusual cabinet shape doesn't allow to carry the box easily the acoustic result prizes the customer, especially if the speaker is used in conjunction with our V series of subwoofers.
