How to make bi-amp setting

Hi Gvasale,
Thank you very much for your information. This site was helpfull for me. http://www.audioheritage.org/vbulletin/showthread.php?24303-JBL-XPL-200-amp-crossover
Thank you, Ted

Checking the net and finding the Lansing Heritage pages dealing with the XPL products, the speaker you have in mind has a 250hz crossover point for bi-amping. And if your amplifiers have over 100wpc capability, you're well on your way. I assume they (JBL) did not recomment any more than a 2 way bi-amp.
