Post Subject: The date with a mechanist.Posted by Romy the Cat on: 10/3/2008
Stopped by last night I saw my mechanist and consulted with him about the section of available material for my MiniMe project. He showed me different grades of steel, aluminum and industrial plastics, gave estimates, positive and negative moments of use each of them. I was touching and playing with material G10 of different thickness. The G10 turned out to be very nice greenish plastic, very pleasant to lay a hand on. It is not wieldable but gullible. I still contemplate if I go for 3/8 G10 that do like or for 1/5 of steel. The price for G10 will be slightly higher but not too crazy. A sheet of G10 good for one channel will be $240. So, two channels + labor is ~ $1000. The steel has twice cheaper price tag on material side and the same labor. With G10 I would need to go for stronger ribs in the middle. I also consider making a sealed divider in the 3/5 of the speaker’s height, separating the speaker on 2 individual enclosures – one time 10Hz below another. I might consider having a pressure EQ hole of unknown diameter in this divider… The Cat Rerurn to Romy the Cat's Site
