Can anyone point me in the right direction for a comprehensive source of information regarding the speaker elements and crossovers in the JBL home lines. For example if I wanted to find out the woofer and crossover network JBL designations for an XPL200, is there a site or PDF somewhere with this info. I have perused the library and get some info, but unfortunately most of the consumer catalogs dont specify the speaker elements. I know the repair places have this info, OCS just plugs at a computer and comes up with the info. Any hints or missed threads on the topic? I know the spec sheets would have this, is there a way to access the spec sheets on line for the majority of speakers.
