Excellent news on all fronts. I really enjoyed your write-up, too.
You know, Duke, with the proper speakers (and the current ones might be just that for some), something like the Birdhaus could make a great guitar cab -- not to mention that, if guitarists can hear themselves better, they might not turn up so much -- the cab would have to be of the right efficiency to operate their amps in the "sweet spot" though -- that and we would be spared the "cone of piercing treble". Amp placement/overhang might be an issue for some.
Just a thought.
Thanks, and one thing I didn't mention is that while I usually play pretty clean on guitar these days, since getting the Birdhaus and experimenting with the Zoom/Peavey/AK rig I have been revisiting my higher-gain youth a little bit, and to my ear the Faital 8PR drivers don't sound bad with guitar crunch. I've tweaked a Zoom model of a Boss ODB3 bass overdrive into a pretty decent Mashall JCM rock tone for guitar and if I set the Zoom's high-EQ "module" for shelving instead of parametric or three-band graphic, I can set a corner frequency (I think that's the right term) of 2.4, 3.6 or 4.8 kHz, and it seems like starting a gentle rolloff at 3.6 kHz, or a little steeper one at 4.8 kHz, gets me into recognizeable guitar-speaker-like top end. If I set the low-frequency module up for low shelving and start the HPF rolloff around 100 Hz I feel like I'm getting realistic-sounding guitar speaker lows too. In between those shelving points I can do broad tweaks with the tone knob function within the amp model. It seems pretty intuitive and effective to me.
One thing I did notice about these drivers in this box is that they are SO detailed and articulate--not always a go-to quality for guitar players--that I really notice now that my guitar and lap steel require different EQ settings. I never felt I needed that before, but it's apparent now that my steel is very midrangy and kind of dark, and needs a more scooped EQ and more presence (so far, that's been setting the high shelving to 4.8k and using a gentler rolloff slope) to sound its best and put across the various glassy steel artifacts. I like the lap steel to sound as much like a pedal steel as possible, and less like a distorted bluesy beer commercial soundtrack.
I have no complaints whatsoever about the Faital 8PR as a speaker choice for this unit.
