  • Center speaker build

    HI, I am wanting to build a center speaker using 2 Dayton RS 180p-4 woofers in a vented enclosure. I have tried modeling it on WinISD but for some reason it keeps rejecting the perameters. Can somebody please help. I know I need somewere between 1.2 and 1.8 cu. I am looking at 2 rectangular ports (1 on each end) aprox .75 x 7" long. Help would be greatly appreciated.

      Within WinISD go to Help and go to the Entering your own drivers section, and there is advice on the order of T/S parameters to enter with auto-calculate turned on.

      Or see this...http://www.midwestaudioclub.com/resources/winisd-a-beginners-tutorial/

        (w/"Autocalc" ON) just enter (in this order): Qes, Qms, (NOT Qts) Fs, Vas, Re, Le, Sd (I like cm^2 'cause that's how its usually spec'd), Xmax, and Pe. No problem.

        Looks like a 1.7cf box would want your 2 slots to each be about 9" long.

            Fb and F3 in the upper 30s. Xmax near 60w RMS into the low 30s.

                Go to loudspeakerdatabase.com and just download the WinISD file for this driver. They have every dayton woofer there.
