Beautifully drawn designs, thanks for posting upSmile

I'm gonna post some hornresp input parameters but please note these are definitely wrong, because I did it by eye when I got home after smoking a plenty last night...

S1 = 715
S2 = 1951
Path length = 155cm
Vtc = 50000
Atc = 1046 (I don't even know how to calculate this so it's gonna be wrong)

Cheers stipe, i got some of those very wrongLOL

Input parameters for HR

S1 = 750     
L1 = 100 CON
S2 = 1951
L2 = 50 CON
S3 = 1951

Vtc = 85000 (85ltr.)
Atc = 1400

"Atc" is average cross section area of throat chamber and roughly said defines shape of throat chamber ..(for example when "Atc" is set small it makes  throat chamber appears long-tube like .. in HR simulation that have effect on throat-end-correction factor and make horn apear a bit longer.

.. HR inputs also added at first post now Big smile

..1 cm more width will make approx 1.5ltr volume in throat chamber ..which really will not make noticeable difference.

Such way my mini's are width-compatible with ES-18 Wink

If one want achieve effect of a larger chamber it is easily achieved by adding damping material in chamber.

However I recommend slightly damping of mini scoop rear chamber at least in top and rear-panel chamber corners all time.
..For effect of bigger chamber - moderate damping on all rear chamber panels (take care to not obstruct air flow at driver unit magnet-vent )

Best wishes, Stipe
