JBL XPL200A The Unicorn speaker?


I found a pair of JBL XPL200A which I immediately snatched up! Anyone that had the pleasure of listening to the XPL200 would agree they are worth the $ to repair. The woofers needed re-foaming which was a given considering the vintage. One of the tweeters (046-Ti1) needs a new diaphrgm, unfortunately JBL stopped producing them but offer the newer version (046-Ti1S) which is supposed to sound identical. However, the replacement diaphragm is 10db lower. We swapped the new diaphragm on the working tweeter and it played 10db lower also. The XPL200 is 6ohm but I haven't seen a 6 ohm diaphragm. Does anyone know a direct replacement or have experience replacing Ti speakers? TIA!

The speakers are wired by JBL for bi-amping. Use 250 to 300Hz., 24 dB/octave slope. Do you have the XPL200 manual?

Woofer is on the low bi-amp terminals and other 3 drivers, 6.5" midrange, 3" titanium midrange dome and 1" dome are wired to the high terminals through the internal crossover. If you need a copy of the XPL200 manual, it's available on HiFi Engine. 

Thanks for the reply, I have the XPL manual. I figured out the key x-over points. Now I'm setting up the EQ manually since Auto EQ is not working. They will be ready to be placed and angled for the sweet spot in a day or so! I will attempt to shoot a small audio clip. 

Many thanks for putting up with the rookie questions. You're an asset to the community.
