EPI M100 finished

These first generation EPI 100's just got a new lease on life this week. It is amazing how good a pair of 40 year old speakers can sound. I am glad these did not end up in a landfill.

I picked these speakers up from a guy that bought them new as part of his first stereo back in the 70's and I am happy to do a full restoration on them.

EPI 100's are a great speaker design from Winslow Burhoe and a very simple in their execution. The woofer digs deep for an acoustic suspension design and can attack the bass notes fast, the tweeter is crossed with a simple 10uf cap in the first order at 1800hz. The cabinets are well built and have a beautiful walnut veneer to them.

At the ripe age of 40 years old the following was done to bring these awesome speakers back to their youth.

Both woofers needed a re foam, which they received.

New polypropylene +/- 5% caps where installed along with upgraded copper speaker wire.

The speaker terminals where upgraded to gold plated binding post that accept banana plugs.

 

While the driver where out I sanded and re finished the walnut cabinets with 2 coats of Minwax natural stain to bring back the natural beauty of the wood.

All in all this was another excellent opportunity to bring this classic speaker back to life. I have had a few hours of listening pleasure with these original EPI 100 and it clear why these musical speakers have stood the test of time in the vintage audio Renaissance. EPI 100's  are always worth the time and effort and should be experienced by anyone who is into vintage audio.
