The JBL's C29AV-1 is a shielded passive 8" loudspeaker with a low-saturation transformer for voice amplification and foreground music reproduction in a variety of indoor and outdoor venues. This public address system can be powered by 70V, 100V, or 8-Ohm power amplifiers thanks to the 110W transformer (available separately). A sturdy 8" Kevlar-cone woofer and a 1" titanium-diaphragm compression driver are included, resulting in a frequency response of 43 Hz to 15 kHz and a continuous programme power output of 300W. The loudspeaker may be positioned horizontally or vertically with its rotating horn.
