  1. I hadn’t gotten one of these emails that someone had posted on the thread for a long time, but I was glad I did. I built my BIBs several years ago. I pretty much stopped reading Stereophile etc. because whenever I get free time, I just want to listen to them.

    • I stopped my Stereophile subscription years ago. The money I saved went directly to speakers (and my children of course – who I built speakers for). I hope you still enjoy the BIBs you made.

  2. I do! I friend helped me build a pair of Single Ended Triode amps based on the 45 tube. The 45 SET tube amps and the BIB’s make a great pair!

  4. Thank you and all the people who had worked on the bib spreadsheet. I went with a fairly small driver, the dayton audio pc105-4. After 10 or so listening hours, i really enjoy the dynamics with this enclosure and it kinda waf too.

    • Mtlsir, yes, even small BIBs sound great. The BIB design offers an open and dynamic sound even if not reaching deep into the bass. Using small drivers allows you to build a very tidy and slim floor standing speaker.

  5. I was wondering…. I just filled in the values and it said that my Line should be around 3 meters. The speakers used is a small 4″ woofer with a Xmax of 4 mm and a FS of around 53. 8 Hz. Qts of 0. 4 and a Vas of 0. 11ft3 . If I do a transmission calculation the tube is around 1. 5 meters @ FS. So this will be a bit longer after fine tuning…. But really 3 meters??? I’m wondering if this is correct?
