That's great thanks, shame I dont do Facebook :)

Hmmm, not really sure, the woofer drivers weigh 12.5kgs each x 2 + approx 13kg for the case so 38-40kg per woofer cabinet. My guess is the Bridge, Top Baffle & drivers weight about weighs about 15kg so a total of about 55kg per side.

I'm overwhelmed by your kind words, thank you again

Thank you all for the comments I appreciate it I haven't posted them anywhere else as yet & your right SO MUCH WORK

My brother and I gave Spotted Gum a nick name "Devils Wood" beautiful, yes, hard YES , cranky YES YES YES Built my sister a table from it. The best bits are figured and the more figure the more cranky. I agreed re the 1.5" being enough.

Whatever you can afford and like 2"would be plenty thick enough.

I noticed the designs at the top of your blog have the reduced baffle dimensions for the mid and tweeter drivers, for what it's worth, I can highly recommend that design approach, really helps the sound stage. Ya gotta love those Scanspeak drivers Whats the big black box between your speakers. Ok it's a sub

You should get more bass if the woofer is closer to the floor.

There expensive to

Thank you, looks mighty fine.
