I need some expert advice. Since it's impossible to find 050TIJ diaphragm/membranes for my 250 Jubilee, my JBL dealer told me i could replace them with 035TI or 035TIA.

They say they also come in gold colour.

Is this a smart move at all? Is there any difference in the sound. Would I loose any "quality"

My last option is to by a complete set of 050TIJ which will cost me a great deal of money :-)

Any input is more than welcome.
Best
Martin
