fe103em = awesome!!!

I am an avid enthusiast of stereo equipment. My latest adventure was building a low power vacuum tube amplifier kit. The kit was very successful. That led to my next need... very efficient speakers. I wanted to have a smaller size bass reflex, bookshelf enclosure. I tried several commercially available speakers. Their touted efficiency was at 1000 hz. There were steep drop-offs in efficiency outside of that range. This would not work...

Enter the fe103en:
With great help and direction from the Madisound team I invested in a pair of fe103en speakers. Combined with a pair of .25cu ft enclosures and a two bass reflex ports I was rewarded with wonderful sound.

For lower listening levels and smaller speaker cabinets you can make a low power (or high power) amplifier sing. For the money these drivers cannot be beaten. I have 10 pairs of speakers and these are my favorites. Absolutely fall out of chair vocals and silky Mid-range.

Clear out your calendar because these speakers will make you listen for days!

Thank you Madisound for such a great experience!
