riley804 Posted September 11, 2000 Share Posted September 11, 2000 can anybody tell me if you can make a pair of forte II biampable??? Quote Link to comment Share on other sites More sharing options...
leok Posted February 19, 2001 Share Posted February 19, 2001 I have been advised to be careful using the term BiAmp. Since you ask the question at all I assume you want to preserve the crossover functionality (low pass for the woofer and band/high-pass for the two horns). I guess that also means you don't intend to perform crossover before the power amplifiers. If all that is the case: Remove the crossover unit from your speaker (mine is a Forte II) and you will notice that the woofer low-pass inductor-capacitor network is connected in parallel with the band/high-pass network. With two foil cuts you can completely isolate the low pass circuit. In the end, in my case, I completely removed the low pass circuit from the crossover pc-board, and moved it (inductor and capacitor) to the far side of the cabinet. I did this because the high frequencies I was feeding to the low pass network, since I don't perform crossover before the power amp, were magnetically coupling to the high frequency section. Be careful. Make sure you completely understand what you are doing before you start making changes. I like the results. I think the imaging is improved with either twin amps per side or simple bi-wiring. Quote Link to comment Share on other sites More sharing options...
jadams Posted March 27, 2001 Share Posted March 27, 2001 I've been looking for this information for a long time. What did you do with the rear connections? I also have forteII's and was wondering if any of the new bi-wireable speakers' contact cups would work on the fortes(klf-30,etc). I was looking into the idea of tube mid/high and solid state to bass. Had also thought about a simple bi-wire setup from one solid-state amp. john Quote Link to comment Share on other sites More sharing options...
Bluesteel Posted March 27, 2001 Share Posted March 27, 2001 What if you did use a crossover before the amps? What I was thinking of was disconnecting the woofer from the crossover, and replacing it with a 8-Ohm "Dummy" load like they use for bench testing amps (they also make 4-Ohm dummy-loads if required). Then using the existing crossover to connect the output from the Receiver (set to either "Large" or "Small" output, whichever is better). While the LFE/Subwoofer signal from the Receiver goes to another amp and then to the woofer. The reason for this would be having an extra Chorus/Forte/Quartet for the center channel, and wanting to use the center speaker's woofer and cabinet as a convienent sub-woofer. Aside from not using these speakers in the way they were designed, is this possible? Quote Link to comment Share on other sites More sharing options...
Bluesteel Posted March 28, 2001 Share Posted March 28, 2001 Thanks, If its only a loss of power from the mid-hi amp, a resistor makes the most sense. That way the original x-over stays intact. Update: Additional information on this topic is in the "General Questions" section under the topic: "2 components.....1 pair of speakers???"
