Hello all,
I believe Ed's speakers are the hidden gem in audio. I am so impressed w/ the DIY that I went on to audition and were immediately sold on his EFE branded speakers.
I have a set of his EFE-T22 for a few years and their transparency and speed is simply amazing and disappears into the living room leaving only the music behind. Generally, speaking, it is extended, crystaline and clean on top w/ out edge or grain. The midrange is very liquid and articulate. Down low, the bass is fast, punchy and has great transient attack w/ great pitch articulation w/o smearing, overhang or bloating.
Put all these together and you have a great sounding speaker system w/o the need for expensive equipment. However, better electronics will only reveal more of the speakers' true nature. One of my best acquisition as far as I'm concern.
Cheers!
