I need to know at least the port tune Hz, and the driver (Fs) resonance frequency would be nice too. This way I'll have a good idea where to set the high-pass at when I get a Dayton Audio DSP-408 with the DSP-BT4.0 Bluetooth dongle. Then I turn off the high-pass on my new Crown xls 1502 before I hook up my other R-112SW to the xls1502. I appreciate your help.
