Way back in the mid 1960’s I purchased pairs of JBL LE-85’s, LE 15A’s and L-91 lenses. The last I used these was in a built-in system on each side of a brick fireplace wall. I removed them when the house was sold and they have been gathering dust since. Something I have always wondered about is what would they sound like if I added either a 075 or 077 tweeter to them? I guess the basis for this is because when I originally bought them what I really wanted was the three way system with the 375 driver, 075 and LE-15A’s but could not afford them at the time.
Over the last 10 years or so I have also procured pairs of 075’s, 077’s, LX5’s and N8000’s to gather dust alongside the LE-85’s and LE-15A’s. Now that I finally have the time I’m thinking of building some boxes to hold a three-way using the LE-85’s, LE-15A’s and 077’s. So my question is, do you think putting a LE-85 in the middle instead of a 375 is worth the effort? Has anyone done this?
