Hi Wayne,

I prefer simple systems to complex, and 2watts to 200. Usually means backhorns augmented. I always use Fostex only. Arguing Lowther Fostex is audio S&M. Ultimately it's the *implementation* that matters most IMHO. I have a dozen amps mostly tubed but some nice solid state amps too.

My Abby model is a voigt pipe. Voigt pipes are the best compromise between a std monkey coffin and a horn.

As far as tuning methods I have eveery speaker builder article relating to high efficiency on my desk. I was a longtime Magnaplanar fan. But started with single drivers and tubes in the 60's because that's all a paper route could support. Built SpeakerLab and did prosound gigs in Seattle in the 70's. Lotsa JBL PA cabinetry for local bands.

The double horn shown is my largest speaker using the fe208Esigma and t-90a. Self powered sub in the corner.
