Agree, Not that large...~45.5" high (if 18mm wood).

What is your application besides being used outdoors?

I will be playing R&b,hip hop and pop music.

The next hard part is to find someone to fold it up for me.

Cut the HR layout in half(=112 cm internal height) and locate the terminus S4 at the bottom of the enclosure facing rotated 90 degrees (S4= a rectangular opening of 46 x 8.78 cm^2).

I calculated with a very narrow internal width of 46 cm and driver should be located at fitting snugly touching the bottom plate . The box external width would be at minimum~46 +2 x 1.8 cm= ~19.53".

Hi Soundhead,

A few more hints:

PS: If you are 'off' a quarter of an inch on any dimension: IMO/IME, This wouldn't cause noticeable differences on the performance.
