I did build last weekend a new box for this driver i had in an old ported box. As i made a better version of that ported box a while ago, i was not listening to it anymore.
I wanted to explore the BBC/Spendor/Harbeth way of building cabinets with thiner plywood box but damped with bitumen, and a thick front and backplated screwed (not glued) to it. So i made this sealed 11.5L box quick, simulated it in winISD and build it in 2 sunday afternoons. The box is stuffed almost fully on the inside and has 5mm thick bitumen pads on the sidewalls and the top and bottom
I did not take many pictures during the build (as it was ment as a test) but i'm so pleased with the result that my other ported box is in storage now and this took it's place in my waw setup in my living. I wonder why nobody else tried this before?
The driver is an old (as a few years and many hours playing) Mark Audio 10M gen 3. I did not measure it yet, but the few hours playing showed me already that this box is way more accurate in the reproduction, and got bass lower than i expected when put close to a wall. And with the sub it works like magic...
