recycling a Mark Audio Alpair 10.2

hi all,
I built two big speakers with my trusted pair of Alpair 10.2 (the metal ones, not paper) some 10 years ago.

I am now in need of a pair of wall-mounted speakers, mainly for a home theater setup - but that eventually, I'll probably use for generic listening in the living room.

I have been looking around for a decent pair of speakers, but then I thought.. what if I recycle those two, put them in a small enclosure (VERY small, like 25(H) x 20 (W) x 10(D) cm ~ 10 x 8 x 4 inches and use them as main speakers?

The enclosure will be so small to screw up all the wave dynamics though.. so here I am again, asking for perspective 😉

What would you say? Is it a bad idea?
thanks and cheers
