Default Slowly does it !!

This one is taking some time because of other stuff that has to be done. Also I am ultra triple checking everything while working with the Tassie Blackwood, because its VERY expensive to replace. !!

Top section is getting there slowly, and lots of work to do on the bottom section.

largish pic files !

Drivers for the top are some left-over Vifa M11WG and the Peerless 80mm flange tweeter (can't remember the number at the moment.) open back MTM.
Bass drivers are 10" Jaycar 120w poly's which have been waiting for a project for a long time, vented, tuned to 35Hz iirc.
X-o will probably be a link series at 300ish and 3000Hz. All drivers have nice flat response in the range asked of them, and no gremlins lurking outside their anywhere near working range, so should work

ie, its a "use up what's on the shelf"project.

How much do you have to pay for the blackwood up there?

Nice work Andy!

I'll be very interested in seeing how you finish the Blackwood. It's such a beautiful timber.

How do you find working with it?

Where did you buy your timber from?

Cheers, Ralph

This piece I bought down in Tassie about 4-5 years ago, when I had my station wagon down there, visiting parents.

This piece seems to be rather dry and brittle, it leaves feathers when routed, rough surfaces when milled against the grain etc.. ie quite hard to work with !

I am hoping to finish with a natural oil of some sort. We will see !!

the brittleness is mostly caused by the fairly course grain, make sure you wear a respirator cutting the stuff (probably a bit late heh), the saw dust is somewhat toxic and can cause lung irritation. When you are routing the driver recesses a spiral down cut bit can be used to prevent tear out, you have to take it slow since the sawdust has no where to go though.
