I have just loaded the T/S parameters of the Beyma 18G40 and it has a fs of 32hz and a f3 of 32hz in a 320l cabinet, and it is available from our dealer here. Do I go ahed with this driver or still stick with the JBL 2241H with f3 of 35hz and fs of 35hz? Will the sound quality of the Beyma's approximate that of the JBL's?
