bringing up the 140 inch path 206E simulation for the third time - look at the first impedance minimum around 32Hz - - FWIW I'd way this is the effective tuning and 1/4 wave of this pipe which at ~5.4 cubic feet is larger than one shown in the BIB calculator F3 is also predicted around 30 or so

Hello Eric,

Looking forward to see how your project develops. I have 140" 206e BiBs in my room and I can tell you that your brother in law will be REALLY surprised. Just find demos with good dynamics and you'll see.

I don't have measuring equipment but using tone generator and my "golden" ear I'd say these BiBs are good to 30hz in room.

Good luck and have fun making saw dust

ps. Yamaha is also kicking BiBs here and doing a wonderful job.
