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!

Congratulations! Multi-amping will blow your mind, just don't overdrive them.

So I ran the EQ with the RTA mic then went to the crossover section where I'm not having any luck in with the settings. Do these setting look correct? I'm using the dbx driverack pa+...there's no mid settings.

If I adjust the mid to tweeter @ 4.5Khz I lose mid frequencies

I read that the xpl200  Crossover Frequency 250 Hz.

While the standard passive point is 300 Hz, flipping the speakers bi-amp switch shifts the internal mid-bass filter to ~250 Hz to align with an external active crossover.

Does the low pass need adjusting also. I don't see a setting for it. It's only for low and high.

Update: my crossover settings are as follows:

for the 12” woofers 90Hz to 280Hz, High/mids 1.2khz


 

Does that look right?
