Yes, too late. Once you've heard a good "stupid horn installation", there's no going back is there?
Yes, something similar to what was shown in Jeffery's GOTO installation. It should work the same on the floor or ceiling, (loading wise) as long as the mid-bass coming from above doesn't sound strange. I'll build them so I can mount them either way, and try them both ways just in case...
Why? Long story, but here's a quick, dis-jointed explanation which boils down to less ripple, less distortion.
The horn was designed around the 80Hz crossover point on Jeffery's suggestion, and everything else around that. I tried Tractrix, Expo & Hypex. When you truncate they're close anyway, but John said the same thing about expansion profile and distortion. Expo & Hypex give a little more bass extension, tractrix has smoother frequency response, less ripples. It's taken me months to get this far, and this is the best yet. It's flat + / - 1 1/2 dB from 80 - 400 Hz, with a slow roll-off after that. The mid-bass was the hardest piece to get to work right on paper, and will probably be the hardest to actually build.
I know many people say not to use tractrix for mid-bass, that you can't annul the reactance with the compression chamber volume, but I'm banking on that not being true.
That's not what the math says, or what people say who've actually done it. That's who I believe.
Like I said before, Jeffery's system sounded so much better than anything else I've ever heard, that I do listen to whatever he says as comming from someone who's been there, done that.
No rush at all on my side! I'm just trying to gather resources.
MF-- Anything you care to share thoughts on.
Mid-bass, low-mid, or high-mid especially.
I doubt I'd mess with the sub or tweeter--I haven't built the sub yet, I'm told THs of this type work fine as is, and I have been using the JBL 2405 and can't fault it if crossed high.
Congratulations accepted, however I must add I feel very lucky, and realize I had nothing to do with it. I think the "perhaps just a smart woman who knows how to live being a women" is what's going on. That and she loves music.
