[quote user="Johan Dreyer"] I had a SG370 mid apart only yesterday.I should have taken a photograph. I have also seen the inside of the tweeter. They are very similar, so I have no reason to suppose the low mid SG 505 will be much different. I'll try...

[quote user="Dominic"]I'd put your sub horns above your head. There are some big issues with that but you save a lot on concrete engineering, and assuming space remains in future you could apply what you learned from the overhead wood horns to a more...
