about the size of a Karlson Twelve with upper bulk limit at 25.25"x 18"x15" (could go taller aspect) and ideally pack a 12 inch driver. (Kappa 12A) A Klipsch Belle at 0.83X scale is close. and at 2/3 scale would be tiny and could be vented with a 10" driver.
I'd appreciate alternative horn - especially if you've got one drawn up
I know it would make noise as my 0.83 Belle (too pretty to drag outdoors and a bit heavy) sounds really good with 12pe32 and a 1.2" neo Beyma driver horn on top.
A 2/3 scale Acoustic Control w-bin would look cool - I don't have a verified sketch to scale. (~48yr. ago I had a 360/361 but traded it off before taking it on any gig - I remember a turn-on/off thump and the amp mounted in the bottom of the horn cab)
A problem with little W-bin is mounting the driver - back chamber gets really tight. IIRC, the Acoustic w-bin has a removable back chamber.
I'm not against a single path design.

Hi,
I’ve been following your threads quite a bit about the scale down W bins and university classics. I made a karlflex for a 6” mini monitor for my musical instrument, much better than the one enclosure from behringer.
I’m thinking the same thing I’m gonna go for my set up of ~95-500hz horn and I have design constraints of less than 20” depth, this classic and belle designs seem attractive. The horn would be Patrick Bateman’s horn from the unitized image waveguide thread (I built two, have not tested them yet) , but those would sit on top.
One design I have played around with is using a large version of the Danley paraline concept. Basically the exit line would be horizontal and with horn loading at exit, thus a big line areay source would be the result. I have an excel spreadsheet I used to calculated the equivalent horn the paraline lens would make. Have to look it up what results were.

Here is something that I have been working on, Dayton PA310-8 coupled to a 24" tall x 12" wide paraline lens that has then coupled to a simple 24" tall x 12" wide parabolic horn wedge. The box works out to be about 24" tall x 13" wide x 19" deep. The response is peaky, but I would be using some DSP to flatten it out. The paraline lens and parabolic horn basically gives you a horn that is 20" long. I need about 100hz-400hz for my application since it would be using the Bill Fitzmaurice T24 Tuba.
I have considered venting. I guess I’ll look into it more as since I am crossing to a sub, I was concerned of the port phase and sub interaction, but maybe I could just crossover before the port, so it’s really about unloading the driver.
One thing I was considering is taking your scaled belle and fitting the paraline waveguide into the Belle, therefore you have a line source coming out the back into the w-chamber. It will Ada few inches in depth, but far less than a straight conical expansion. I’ll see about modeling that.
I bought plans for the bill fitzmaurice omnitop 8 using dual eminence woofers. They are on sale at Madisound. That was a compact horn I was considering too for 100-400.

Beta 8A at less than 1/3 current inflated price - very good driver -I'll have to look at Bill's cabinet.
@dr suad -might you draw a rough concptual sktch of how the paraline fits into the scheme ?
Hi Nigel - I'd love to have that Fane horn - too large to ship money-wise - I've pretty much lst all strength in both arms - frozen shoulders awful tendon (?) pain up and down both arm,s from shoulders to wrists -bet it would be lots of fun for bass guitar.
