From the designer:

"Here is a new design I have just completed.It is based on the famous Tapped Horn as discussed by Tom Danley.This design offers many advantages in terms of efficiency compared to a reflex but also mainly in its "musicality".

The idea for this box came to me after discovering Tom Danley's MiniTH, I ahve always been impressed by its products.

IN NO WAY is this design a MiniTH copy(I don't even know the internals of the MINITH anyway).This plan is 100% original, based around a specific driver and the design is very close to the MINITH performances.

The inspiration for the design was to make a small enclosure, with a inexpensive, but quality 12" (DIY spirit) able to compete with a 15" reflex.

The enclosure is based on the Precision Device PD.12SB30.Efficiency is 100.5dB 1w/1m in Half-space (2pi), cutoff 52hz at -3dB.

I recommend 15mm seing how small the box is, should make for a very light cabinet adapted to mobile djs, or bigger PA with multiple enclosures..."

I'm not sure about the last horn part....the driver occupied a lot of space so...s4 would be around 411

cheers, bitzo

Thanks, But what is the SPL???

we have to wait the designer reply but if you are in hurry, hornresp is your friend.
But to me is wiser to wait....sim is useful but the real testing and build is the real answer.
