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 2 replacement JBL 046-TiS1 were installed and sound exactly as designed. I'm also happy they are the updated drivers which the XPL200A should have. Oddly, mine were the original 046-Ti. In any case, they sound incredible when using the internal x-over. Music sounds fluid, vocals are airy, and the mid range is tight and yet agile, effortlessly taking up the upper and lower mid ranges.

Hard to imagine bi aping will elevate it even more. I'm having a heck of a time with bi amping, adjusting the crossover and Parametric EQ for the highs/lows. There's not much info online for the dbx PA+. 

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.
