I've been looking for used 035Ti or 035Tia replacements recently and have noticed that they're getting more and more expensive. They're no longer available new, nor are the diaphrams, from JBL. I'm aware of the 052Ti as a drop-in replacement, but it's a little pricey. The 052Ti diaphram is also available, but they're about $60 each. And Midwest Speaker is making copy 035's for about $80.

I was wondering if anyone has used a different tweeter as a replacement and has been satisified with it. I'm not talking about a tweeter that will be an exact match, but rather a substitute that will be "acceptable" for secondary listening uses (garage, workshops, etc.) that won't be too expensive. Modifying the cabinet opening is okay.

When looking for a substitute, the only spec I have to go on is that the 035Ti is 92 dB efficient. I don't know what it's FS is.

So, does anyone have any ideas?
