Hi,
I know I have read on this forum people asking about the weight of the various designs. I weighed what I built today and I'm posting in the Build section as I wasn't sure where best to post it or if posting such info is allowed. If it is not, I apologize.
My OT's with Kappalite 12's weigh 40 lbs. Melded array with no grills but one metal hat.
The T39, at 28" wide with Kappalite 12's is 80 lbs.
A Kappalite driver is spec'd at 7.6 lbs.

In new money thats:
18kg for the OTs
36kg for the 28" T39
Kappalite is 3.5kg
No point in all of us doing the same calculation!!

When I worked at a bike shop, everything was metric. I could look at a bolt across the shop and tell you what size it is. Now I work with strictly imperial measurements and struggle to find the right socket or wrench.
Don't even get me started with American cars that have both types

I'm one of those 'transition' guys. i was in my teens when the UK started to go metric with currency, measurements, volumes etc...
So most of my schooldays were in imperial and in pounds, shillings and pence. All of my adult life has been in millimetres, litres and decimal currency...I much prefer metric, although I do all of my BFM building in inches ( I don't bother with metric conversion, even though I find millimetres a much more convenient measurement system than 1/8, 1/16, 1/32 etc). Bizarrely, in the UK, all fuel has been sold in Litres for at least 20 years but we still measure fuel economy in miles per gallon.
