You need to go inside the speaker to access the crossover. Then disconnect the tweeter and add a cable from the tweeter to the upper binding post. Connect your tube amp to it and use your active crossover to adjust the sound level. Leave the rest of the crossover alone. Do not tri-amp the 4367! Tri-amping will only muck up the sound! The stock JBL crossover is designed to have the three drivers work in harmony, particularly between the bass and mid drivers. You can get away with fooling with the tweeter response but not with the bass and mid output levels.
BiAmping JBL 4367 Speakers
I was considering running a tube amp on the horn portion of the JBL and keeping a solid state amp on the woofer section. My Trinov preamp has a fully adjustable electronic crossover, so I could set a crossover point for 700 Hz for the amps.
The question is would it hurt to use the external binding posts to each driver section of the speakers and leave the passive crossovers in place. I suppose I could eventually bridge the connections in the passive crossover and go directly to the drivers, but this is just a trial to see how things work.
Any significant problems with doing it this way?

My bad. Fiesta and JB71 are correct. For best results you will want to bypass the internal crossover. JBL assumes you will not be using an external crossover with their method. @fiesta75, @jasonbourne71 It is my understanding that the 4367's are a 2-way speaker, why would there be a need to tri-amp? |
JBL speakers are very carefully designed and built. In my experience they generally cannot be improved through bi-amping. In fact often quite the reverse is true. Whatever you do try not to do something that you cannot later undo. There are speakers that lend themselves to bi-amping that are greatly improved when this is done. JBL is not one of them. I hate be the naysayer here. |
Sorry for the incorrect info. The 4367 is not wired for bi-amping like the other JBL 4300 series speakers. I should know better than to assume! audiorusty - JBL lists the 4367 as a 2-way system, but it actually has an ultra-high frequency driver in addition to the midrange horn. I'm not familiar with the internal wiring setup, so I do not know if you can actually access the voice coil wires for the UHF driver. |
