  • does this winisd result look right? ND65 with two peerless passives.

    guys, at the moment i'm thinking of doing a few things, but one is revisiting a old project but changing a few items to see if it gives any better or worse results. I've always struggled to get anything decent out of the 3.5inch passives from Peerless and have 3D printed an enclosure for a smaller build and thought i hadnt tried this combo yet.

    Dayton Audio ND65-4 as the full range driver coupled with

    I have had some mixed results on occassions using Winisd which made me think potentially there is a mistake somewhere i havent picked up on.

    I know there are a few builds using those pre fab boxes around that 0.04cuft size with Passives that made me think maybe it is ok.

    thoughts?

    I think your model IS okay.
    My curve looks different (but F3 should end up between 60 & 70Hz) - I use ISD 0.50a7.
    Biggest diff. is probably 'cause I'm using my OWN DATS data:
    Qes=1.02, Qms=4.3, (Qts is 0.82) Fs=138, Vas=0.008cu.ft., Re=3.4, Le=0.44, Xmax=3.5, Pe=15, Sd=16.6sq.cm.
