I have searched the forum, but cannot find any specific info on the tuning freq (or vents used) on the various 4310/4311/L100 models.
These all had an interior cabinet of ~1.75 cf (if my math is correct based on 3/4" walls).
What was the diameter of the "hole" in the unvented (=3/4" vent) units?
What length vent tubes were used? (?same diam as hole?)
What frequencies were they tuned to? (easy to calc from diam/length or vice versa!)
If anyone has this info, a simple chart with the various options might be of a lot of interest!
Thanks!
