Single Tannoy monitor red as a sub?

[Brisso57]

HERESY WARNING & DISCLAIMER: Any persons of delicate sensibilities who feel they may be at risk of "going postal" pls read no further. :-)

I scored a Tannoy monitor red 15 at the flea market today. Unfortunately just the one.

Until I can obtain another, I was pondering the use to which I could put this one.
(Fear not gentle souls, when I get a second MR, the cabinets will be built!)

I listen to music at moderate sound levels, and in a listening room that isn't huge.

I don't currently have a sub, so I was contemplating building a cabinet and using just the LF driver. From the web, Fs = 32Hz, Vas = 266 litres.
(See www.44bx.com/tannoy/Tannoy_ts.html#anchor43934)

Is the above a feasible idea? (Given that I already have the driver.)

cheers
