Help with an old subwoofer

[John Link]

In my truck, I settle for thump. Otherwise I like it clean too. One system uses bandpass subs that also serve as printer stands and work down to 20 Hz. The other has a Sunfire sub that reaches 18 Hz. Both use sealed enclosures to control the drivers, which typically controls excess motion from the driver better than ported.

Once you put in a new passive radiator, your enclosure will be much tighter (not quite as tight as a sealed box, though) and control the excursion of your driver much better. Basically, your cardboard/tape left a huge leak, not to mention messed with the original TS parameters something fierce.

But, you don't want a pure sealed box with this speaker. Clearly, the box volume and driver characteristics were selected to work with a passive radiator that moves (and moves some air in the process). Sealed boxes do not move.

I'm just checking with parts express to see if an installation kit comes with the speaker.
