Anyone here using vintage speakers?

I recently bought a clean pair of 16 ohm Altec 604Es in nicely-made but non-Altec cabinets. The crossovers are original too (N1500-A) but I have a pair of 16 ohm Mastering Labs crossovers on the way.
These will be the 4th pair of Altecs I've owned beginning in 1960 (!) with a single 604C in mono then a 604D picked up new in 1962 for a stereo pair.
I replaced these in the mid 70s with a used pair of Model 17s with 604-8G drivers. Five years ago I bought a pair of Model 19s which proved too big for our small home. My current 604Es are in smallish cabinets and work very nicely with 3 10" JL Audio subs.
Anyone else using the ML Xovers?

I only have vintage.  Infinite Slope Model 1, Dahlquist DQ12s,  ADS L1290 and finally the set that made them all expendable Speaker Lab SK corner horns.
Nobody asked but I also have vintage equipment.  2 Dynaco ST-70,  SAE Mark XXIV, the original owner of  Luxman M2000 and  Luxman CL-35 preamp and also a Hafler DH 500.

My current stable is Infinity qB, Infinity RS1.5 and JSE Infinite Slope 1.8. The JSE's are the best built and most impressive looking. But the Infinity RS1.5s are my favorite sounding speaker. They even survived a pair of Vandersteen 3s I bought to replace them....

Kef r107's for keeps ... after Nautilus 802, Sonus faber Luito towers, Avalon eclipse, Klipsch RP-8060FA,  Tyler acoustics,  snell E3's, Type D,  vienna acoustics..all sold. But can't let go of kef 107.. I guess it'll be forever. 

I still use and love my IRS Beta
