Passive Radiator

[Nestabilz]

Thanks. That's the exact thing I wanted to know.

I have not tried the WinISD yet, but perhaps this is the time to do so, I've been working on JBLspeakershop 1.0, but there's only one item of PR to input.

Boston Acoustics Subwoofers

Came across these for mobile audio use -

Boston Subs

Product Manual

They have a passive radiator called GTR that you can change the mass loading from the front without removing it from the enclosure.

Those BA PR's look nice, but ridiculous prices (>$100), as they (PR's) often are.
