How old are your speakers

The oldest everyday set is my Altec "home brew".

I have some Bozaks probably contemporary with the Altecs.

One EV cornerhorn from the 50s.

Then the WE 12a & 13a probably close to 90 years young.
These are not the plywood horns.

Merlin VSM Basic since 1997. Listening to them right now.

Bought my Musical Fidelity MC-4s in 1987, so they're 28 years old. These are Martin Colloms designed two-ways with a see-through TPX 8" bass/mid and Elac metal dome tweeter. I enjoy rotating them through my secondary system where I additionally have Spendor SP-1s (also mid-'80s), Revel Performa M20s and Usher BE-718s. Shockingly, of the listed speakers the MC-4s "disappear" best.

Wilson Audio Maxx3's will be a year old in December! Former speakers owned were as listed. I'm done finally as I have reached my goal.

I forgot to add the Altecs date to 1968, but I have a small pair of Montereys which are several years older.
