So are the RE and BL figures I entered above correct? Why does the JBL brochure state 0.96 for VC Dc Resistance? is this different when both are wired in series for a 4ohm load hence the figure 3.84 you guys mention?
With the above figures I have used, and a 600w input I am looking OK in WinISD, even with a 700 litre cabinet I look OK, it seems to have a more even maximum SPL line with less tail off than 506 litres? An extra 2 to 3db around 20hz? 114dB at 50hz down to 113db at 20hz with come excursion peaking at 7.9mm at 14.90hz and port velocity peaking at 13.572 m/s at 18.77 hz with four 4.02" + 10.85" ports
Cabinet size and design seems quite a lot of work, so I am still busy calculating what braces and battons and such equate to what volume........
