but why? I'm sure there are better modern drivers and more scientifically based designs available today?

In response to you query why build it, i guess i am old fashioned i like transmission lines in particular the complex carpentry involved. I originally built a pair of hi-fi answers back in the seventies and enjoyed the project but unfortunately had to part with the speakers over 10 years ago (marriage settlement she refused to let me have them they were that good).This is why i built them again. I also do not have the time available to go through the process of matching speakers and the designing new crossovers. Thank you very much for the info you sent but when i tried to read the text and dimensions they were difficult to read.Any suggestions.

Turns out i only scanned the plans... i have quickly assembled the work in progress to a pdf that hopefully you will find more readable.

Tony, I'd make sure you can get the drivers before you start making sawdust...

In the first picture, it looked like it was open just behind the woofer, which I really thought was very odd, but I see from the pdf's that were posted, that it isn't. At least , I sure hope it isn't. ![]() Either way, it seems pretty odd to have a mid enclosure that blocks half the bass TL !!! ![]() |

Dave Thank you for the PDF files they are great. Would you have any ideas where i could obtain crossover details ?. I have a spare pair of B139 drivers plus a couple of celestion HF1300 mid range drivers, the rest i will obtain from ebay and ship to australia. I did this with the speakers i have just completed and it was not expensive if you know the tricks on how to ship.
