Hmm, the JBL part number for a 4ohm diaphragm would be D4R046ti. What you have specified is for an 8-ohm diaphragm. Was the 1S diaphragm you installed a genuine JBL part? In a sealed JBL box?
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!

It’s 8 Ohms D=diaphragm, 8R=resistance and O46TI is the driver. JBL Technical Manual XPL200A(diaphragm replacement) see below: file:///C:/Users/ditus/Downloads/XPL200a%20ts.pdf Mike |
