Default MultiType Subwoofer

Hi All,

Can somebody advice me a 10 or 12 inch woofer that would perform reasonable in multiple types of subwoofers?

Oh, I want to build a pretty large sized subwoofer (35 cm x 50 cm x 200 cm), using two identical woofers, which I can relatively easy transfer from one type to the other. That is a removable back panel and internal panels, from the outside always looking the same. See picture below.

To compensate for a volume that is too big for a sealed or ported design, I am planning to just add a bag of sand in the specific compartment.

At this moment I am expecting most from the TL design...

Somebody experience or advice?

Best regards,

That is one ambicious project. I think the box will be hard to design properly.
As for the driver matter, I would recommend Infinity Kappa Perfect VQ subwoofers. Their Q factor can be varied from 0,3 to 0,7 just by changing removable metal polepiece inserts so it can sound good in various boxes.

I'd suggest any DVC subwoofer and use one coil for changing the Q factor. Acoustic Elegance AV12, Adire Audio Shiva 12, Dayton DVC...
