Greenboy cab for home stereo speakers?

My preferred solution to double duty would involve DSP and bi or triamping. Too...much...pie!

Eh....I may be getting things confused then. I take the Fearless line to be a bit more controlled, not quite as extended huge bottom, and some smoothing in the upper mids. Switching one to FearFull voicing would mean removing the smoothing from the mid, letting it pretty much run out of range on it's own and passing the tweeter quite high, like 5-6 khz?

Anyway, I'm thinking the smoothing circuit would make a nicer, less "raw" sounding upper range for music listening.

My intro into HiFi was two Altec A7's with multicell horns feed by McIntosh MC60's, McIntosh preamp and Ampex reel to reel with direct copies of master tapes. The man hid the A7's behind drapes of grill cloth for his wife. It is very had to find anything that sounds as sweet as that did.

Klipsch also had some outstanding PA speakers, the KP-250s that were repurposed and ruggedlized Heresy's. JUst over 100 dB/1 watt/1 meter sensitivity

I think the only real difference was changing the woofer (a 12) to something with better power handling than the home version and losing the wood veneer finish for something suitable for MI/SR. Picking up a pair next week from a local band that's switching to QSC K-10s, can't wait

Actually I have a pair of those klipsch ruggedised heresy's with the after market softer linen tweeter diaphragm + crossover mods etc.
Yeah they are great little speakers.

His HT subs have smoother response and reach much deeper, albeit at an SPL penalty (compared to his other horns). The Prosound subs bring it in the bandwidth that really counts in live sound and bring it loud. The Tuba series is a bit of an inbetween that's popular with the DJ crowd. Combination of lower extension needed for recorded music, at an SPL level that can play raves, etc.......all cool stuff. I have Titan39 plans, but haven't built them yet. This spring and summer, my PA is getting a big transformation.

would like to hear about what you did with those, always looking to improve things if possible

I stopped fallowing his designs after I bought the plans on E-Bay from him back in the early 2000's. They were a disappointment for me and my views are shared by two other engineers I have had PM's with.
Go ahead folks string me up by my thumbs My experience may not be yours.

Right, but I was suggesting something more like switching a fEArful's voicing to something smoother, not the other way around.

almost identical to mine, just swap the Altec's for the big Klipschorns tucked into the corners and a Cornwall (IIRC) for the center

A "good" friend picked up a pair of corner horns for cheap a long time ago. Never could talk him out of them, but we still speak...... occasionally

Ahh.....got it, right then. Looking at Fearful components, most of the hifi "fixing" would be done at the upper end of things.

The 12" with alpha6 and different tweeter integration could work acceptably well, which pretty much brings me around to what you were suggesting in the first place.

There is a solution in the works that is applicable to 12/6/1 and 15/6/1 designs. Details should be available soon.

I will try to look out the guys details, he was offering after market soft dome mods to the old Electrovoice phenolic's and a mod to slightly reduce the pad and a better caps. He was on the Klipsch forum when I found him, I think he makes other midrange diaphragms like the old simbiotic Altec ones for all the klipsch stuff.
He sounded pretty old, I hope he's not dead yet.

I decided I want a Fearful 15/0/0 for my hi fi with one of these bad boys clapped on top of it:

No that one isn't Altec or Klipsch or JBL, its a mighty Vitavox 220Hz multicellular.
One of the Vitavox S6 2" drivers will be very smooth on that, in at 300Hz with ample handling power(believe it or not) and out about where the great old JBL 2441 compression driver with the original aluminium diaphragm fell off at about 16k. Then I just want Coral super tweeters.

Don't want much do I?.
The Vitavox compression drivers sound even better than the ALE low midrange drivers I have heard to me. Not even a trace of honk!.

much appreciated, thanks, PM if you like

This thread has turned into a bit of esoteric and way cool stuff!

Esoteric may not be the proper term, more like just appreciation of things that were figures out decades ago. Maybe lost their "flavor of the month" luster, but their quality stands just the same.

In any case.....way cool stuff.

back on topic--
I have a lot of experience with all of the cabs mentioned. I would say that the new F112 would be really good for both. I think it's the best sounding Greenboy design. The Faital driver for the mids gives a much smoother response.

By the way---the Big E guys that I work with had a horn from the 30's or 40's. It's about 14" x 30", is made of cast iron, and weighs about 80# (maybe more!)

Well you would be the one to know, I have only heard the 15/6/1, These days I also like to limit the size of drivers in my control room monitoring to 12" bass.
I just go crazy in the drum room monitoring.
Your mates cast iron horn isn't an old Thomson Houston is it.
80lbs Well at least at that weight it won't wobble about much.

F112 for sure. The fEARfuls imho aren't right for PA work. Greenboy has optimized the crossover for bass guitar. No reason they won't work if you're willing to put in the time to adjust it. But xover work is not easy. The alternative is the TC112. Duke came from the hifi world, where he's a well respected designer.
