*): add additional 2,1 L for woofer! |

formula: outer diameter [dm] square times 3,14 devided by 4, times length [dm] |
|
|

ports should be rounded (aeroports)! In cases where round tubes don't fit, |
|
|

channels with same cross-section (rounded at both ends) may be built. |
|
|

damping: sealed encl. Fill loosely with poly-padding, vented encl.: 2 walls covered by acoustic foam. |
|
