[QUOTE="johnc, post: 85111, member: 2084"] Thanks Ludo. That's a lot to think about. Unfortunately, option 4 is looking quite attractive. I measured the drivers and they are quite different. IIRC, one has Fs of 70 and the other 77 with a slightly higher Qts. (can't check now... My pc power supply packed up. Will my bad luck please pause for a while so I can get on with this project?) Thanks to JimGore for the the tip of using a R5 coin as added mass for Speaker Workshop. I don't even need a scale. ;) Anyway, I'm thinking I can make the boxes the same externally and then put the better driver in the box with less internal volume. Where can I get some thinnish copper or aluminium flatbar/busbar at a good price? I'm based in Alberton. I have many uses for copper although aluminium is fine for this project. [/QUOTE]
