Up for auction is A PAIR (2) OF JBL PROFESSIONAL MODEL 2104H 4-INCH HIGH POWER CONE MIDRANGE TRANSDUCERS .This is the Cone High Midrange Device that is used in the VERTEC ARRAY model VT4887 Loudspeakers Systems, the latest version of the legendary 2105. This is an 8-OHM Device. Since this model is not sold separately, I don't have any other technical specifications. Suffice to say that they are certainly outstanding speakers for them to be part if JBL Professional's "Flagship" Vertec Line Array Concert Systems. These speakers are lightly used, but in excellent condition, guaranteed to meet or exceed factory specifications.
