Hi everyone!
At Andy's Site of Audio Engineering Topics (diy-audio-engineering.org) I found a link to download several LTspice models for Vented Box designs. I would like to make a small contribution to them adding two more models for closed box and 4th order bandpass designs. To verify the correctness of these two simulations, I compared their results with those obtained with Brian’s Steele spreadsheets which were offered to download time ago in his site diysubwoofer.org.
I use the Dayton Audio DC160-8 spec's for a closed box with Qtc = 0.5, 0.7, 1.0 and 1.5 and the same for a Qbp = 0.714 with S = 0.7 and a Qbp = 0.833 with S = 0.6 bandpass. I found good agreement between them as can be seen in attached plots.
If you try the LTspice models I'm attaching, I would like to read your comments.
Have fun!

I needed to change the "subwoofer.asc" file because was not the one having the DC160-8 data. I apologize for that.
