EPI & Epicure Speakers:
The Epicure 1000
It is an incredibly simple solution to the problem of increasing power handling and bass response without losing all the careful design efforts invested in a high quality bookshelf speaker (the EPI 100/Epicure 10).
By using the smaller system's parts on every side of a square column, power handling is boosted by a factor of four - or, at any given power level, each driver is working 1/4 as hard and is vastly less prone to distortion. By carefully selecting the woofers used, the much larger "per-woofer" volume of the box takes advantage of this drivers ability to respond to very low frequencies when used with the right amount of air behind it.
The crossover can still be the minimalist single capacitor used in the smaller "module" speakers, since every bit of the engineering that made this work beautifully is still present.
The power rating given below of 60 to 250 watts is a bit conservative. These speakers sound great when played quietly, only consuming a few watts per channel, and will easily handle 500 watts each. I would say that 650-700 watts rms would be fine.
Given the impressive stature of this system, and the fact that I build woofers and tweeters that are exactly the same (except my parts are better than the originals!), it only makes sense to encourage people to build this system for themselves. The box is fairly simple, and can have whatever cosmetic effect you desire if you build it yourself. The resulting sound is phenomenal.
I should know, I have a pair of EPI 1000's in my living room... and if I ever sell them, I will build some more to replace them.
