ESS 689-1012 10" Cast Frame Woofer Speaker
Whose equations were used to arrive at a vented volume of 2.51 ft.³?
The Thiele-Small specs I measured on my pair are QTS= .51, VAS= 2.38, FS= 40hz. The resulting cabinet size (using the equation Vb = Qts 2.87 x 15 x Vas) is 5.2ft.³. I am very disappointed.
This volume was determined using the manufacture specs from our website and BassBox 6 Pro. When I punch in the parameters and hit "Suggest" I get a volume of 2.516 cubic feet with a tuning frequency of 21 Hz and F3 of 22 Hz. Your Vas is much higher than the manufacturer, how did you calculate this number?
