The ribbon driver has yet to gain wide acceptance, but maybe the new QR Series from Alcons Audio is just the thing to do it. Designed for use in churches and large halls, this line source system utilizes an 18" ribbon driver and three 6.5" LF drivers, offering 120° by 19° dispersion. Available in two forms, Q36 and Q18, the former is merely a vertical doubling of the Q18. This two-way system has a frequency range from 70Hz - 20kHz with an SPL peak of 150dB (QR18: 144 dB - presumably at 1m).
