JBL 4309

JBL mini monitor – Invoking uncle Albert's law of relativity, when you've got 12" and 15" monitors already, a 6.5" variant is certainly a mini. Hello 4309 [$2'000/pr] which marries a twin-ported 165mm paper-pulp mid/woofer to the company's familiar 25mm polymer compression tweeter loaded into a rectangular horn. A tweeter contour knob allows ±1dB trim in ½dB steps. 87dB/2.83V/1m sensitivity and claimed -6dB bandwidth of 42Hz-30kHz round out the specs and a 1.6kHz filter handles the frequency partition. One trim version sports JBL's 'iconic' blue baffle as shown.
