Hi folks, it's been a while since I last posted. I have dabbled with horns and high efficiency for the best part of the last 20 years, bit of an addict you could say, but following a recent house move I have had to 'make do' with a pair of Castle Winchesters... Whilst I miss the air and openness of good compression drivers in the upper frequencies, I must say I am rather taken by how the Winchesters do bass, especially considering their very domestically acceptable size. With the right amp there is a lovely sense of articulation down below (and they go quite low). This has given me ideas for a DIY system using a similar driver layout, i.e. one front firing, one upward firing (as illustrated by the cross section below), but using bigger and more efficient drivers, say 12" or even 15". I have a pair of of 400Hz 2" Stereolab horns waiting in the wings, which I could use for the HF. Any thoughts on which drivers could be made to work in this context would be welcome, or for that matter any feedback from those who have embarked on similar projects 🙂

If it is high efficency you are after there are 8" drivers that fit the bill. Going for 12" drivers with the same geometry means 3 times the box volume and 15" about 8 times!
The cabinet is a voigt pipe not a horn, similar to this

That is a folded Voigt. It should be modeled. And it should be Mass Loaded as well.
Same folding as Mileva and Demetri, but 2 drivers, one on the side and one on top, with the terminus out the back.
We have found the Castle arrangment in these (named after their Castle speaker) in the microTower clones works very well. https://www.diyaudio.com/community/threads/microtower-bipolar-ml-tl-for-chr-70-or-el70.148901/
