I used to use these back in the day. Great subs.

IIRC I used to run them in around 3-3.5 tuned to around 33hz...but is has been a while and I would have to check to be sure.

That'd be a great sealed box sub if the fs were lower, but you'd be better off with a ported box to get the low-end you need. Going off of the t/s listed, like any other mid qts woofer without a low fs, it's going to want a larger sized box and lower tuning. WinISD is showing me 5.5ft^3 tuned to 30hz for a "flat" box, but even something like 4ft^3 with a 32hz tuning looks pretty decent.

Yep, RAM is almost dead on. I was just looking at some of my sketches from a while back. Looks like I was using 4.75 after displacement and tuned to 34hz.
