Another Aussie - aspiring to design and build from scratch!

Hi,
I have a long history of dabbling with DIY speakers - I dived in with a KEF Concerto kit in 1975 at the tender age of 15, then after a long hiatus starting around 1990 I designed and built some Home Theater subwoofers (1 x sealed, 3 x ported and 3 x IB) and built a set of three DIY Sound Group "Elusive 1099" kit speakers.

I am now retired and just for the fun of it I have decided to have a crack at designing a pair of bookshelf speakers from scratch. I am about a week into it - the drivers have arrived and I have a basic cabinet design. The remaining bits and pieces are on are on the way so now it get's serious - the next step is to build the cabinets and take some measurements so that i can start a crossover design. So much to learn....
Cheers
Bill
