Howdy Guy,
yeah, the weather is nice here, it's like this all year round. Sorry to rub it in.

This summer has been our coolest by far, other parts of Oz have been sweltering. Even a bit of rain hasn't gone astray.
The dimensions are as per Imperial, minus a couple of mm to allow for the fact that we used 18mm chip, i.e. the horn dimensions are pretty much to plan, had to use some 22mm chip on the rear of the speaker chamber to bring the horn shape back into spec.
Jake is such a top lad, shame he and my daughter are no longer an item, but that is life, we progress and I'm sure that Jake will. He has good music plans, and now, he will have the speakers to deliver all his ideas in Kodachrome sound. They will probably be shipped up to his pad in Perth around the end of the month, though I'm sure that if they need a baby sitter, if he goes travelling, they will have a nice spot back at my house.
On the subject of 'house', I'm thinking I might grab the 'Housewrecker' plans off Steve, probably go for the 2 x 15" cabinet. The drivers in Jake's Imperials, though some might say are a little underpowered (120 or so watts rms), should be ideal for a loungeroom, and from what I have read, I could probably design the box to shape up as a nice bit of furniture.
These plans by the way are going to go on hold until at least 2007. A trip to Europe (I was born in England), World Cup soccer, and an attempt to manufacture, cast, plastic telescope mirrors is my next venture. Its worth a shot, isn't it.
Wish me success.
Oh, by the way, Jake bought me a plunger Router for Christmas, what a tool it will be, can't wait to fire it up on the new project.
Cheers,
Gary.
