Default Tube speaker with a twist

Ive got a couple of new Vifa 7"woofers'(BC18SG69-08) that were give aways and 2 HiVi tweeters (SD1.1-A ) that were quite cheap from Darcher Audio.
What I thought was and Ive got nothing to lose, what would they sound like in tubular enclosures (7'and 4') made from 8mm stainless steel?
Would this unusual combo work?
I work on a very large industrial plant and mine way out in the Australian outback, we use tonnes of SS piping and new but discarded offcuts are plentiful.
I thought it would be interesting to make a set of speakers for my donger (mitesite room) that reflected the environment I work in.
They would be stacked lengthwise and mounted on 600mm x 40mm SS pipe with 250mm x 30mm thick pipe flanges as bases.
Ill do a quick sketch if you in the know think the enclosures would work.
Im going to get a couple of Trend Audio TA10.1 amps and use one in the medical centre and one in the room.
I have too much time on my hands I know.

Hi,

The end of a tube is pretty bad in terms of diffraction ripple but that
does not mean it will not work - it depends how "right" you want
to get them to be.

SD1.1 see http://www.zaphaudio.com/tweetermishmash/compare.html

Thanks. What is diffraction ripple and does it come in any other flavour? Im partial to raspberry.
I take it it isnt good but how bad is it?
I chose the tweeters on the bits of Zaphs testing that I understood, which wasnt much.
"Nice performance for a tweeter of this price, and probably worth the few bucks more than the K1"

I will have to 'suck it and see' (an expression rapidly losing favor these days).
The speaker system is not really meant to be the last word in HiFi as it is for a mine camp room. Low volume and thin vibrato walls.
I just dont want to spend the effort only to have it sound really bad.
Thanks
