Don't sweat it. Just take a picture or two at each step and say a few words - or as many as you want. Don't kill yourself. Just for fun!
Well the subwooferless RC4, it's matching center, and Tempesta Extreme will be veneered in the next few days. I did take a few shots of each for posterity. I'll post what I have. Speakers dont look nice under construction. They look nice only after being veneered and polished and if you ask my wife or her friends they all say my speakers are too big and ugly. There is little I can say when the country believes that Bose is the epitome of audio.
For the towers I have used 30mm MDF for the baffle and rear. MDF allows you to rout the basket frame. I will also add a 3-4mm thick rubbber gasket between the baffle and the basket of the drivers. This will be compensated by the thickness of the veneer (about 4mm).
For the center speaker (it is 48" wide, 16" tall and 4" deep at the top and 6" deep at the base) I have used 15mm ply as the depth of the speaker had to be kept under control. However the baffle was braced at 7" intervals to reduce flex. I dont work from drawings. I make a sketch then cut and make adjustments along the way. The center has a W12 Excel mid and NeoX 2.0 tweeter flanked by a pair of W18 Excel woofers.
