I have the all parameters for jbl sub cs1215, Qts-0.54,Qes-0.57,Vas-76.7 Lts, Fas-28hz, Xmax - 12.1mm ,Dia -12",then the Vb - 31.57 Lts at Qtc-1,
At sealed rectangle enclosure,L-12.5" ,H - 20.25" D - 7.5" , So i m confused, because diameter is 12", So give any other dimension at that volume for any other type sealed enclosure.... Regards , Gnanasundaram |

As per the dimension W x H x D for Vb=31.57lts looks like it is followed for "Golden Ratio" rules for reducing standing waves.But IMHO, i feel this ratio may not be valid for "real Subwoofers" because the wavelength is too long for it.
