What to do with a Shiva

Somebody in Melbourne is downsizing and I've just agreed to buy a lightly used Shiva from them.
Comes in a box but I think that the supplied box might not be the best
So what's a reasonable compromise sealed box for a 12" Shiva driver and how does any of the current Dayton subs compare?
Haven't picked it up yet so I don't know which version it is.
But I think I can afford to take the chance at $50-
 
Are you referring to a old Adire Shiva?

Dunno about sealed, but I have a MkII version in a 100lt ported enclosure tuned to from memory too mid twenties, been thumping and rattling windows for 20+ years with no subsonic HP on a old Jaycar 300w plate amp!
Use to be really good in my old small lounge room, but struggles in the current room(8mx12mx2.7H)... time for an upgrade soon
 
Well It is a Mk 3 and I maybe bought a dud but the box is worth what I paid, 25mm HDF and I can barely lift it.
It came with the power amplifier not working and I have no idea if the amp is worth working on [ definitely not my skill set] but it has a couple of ELNA 8000uF smoothing caps and what looks like a 300VA toroid.
 
Obligatory photos of the box and the Silicon Chip amplifier
Driver is not a dud and works fine even tho it has some silicone on a crack in the surround and it has been modpodged.
I had to pay $60- as I misread the original add

Just add another sub or two ?


This box turns out to be 54 litres once I add in the volume of the plate amp section, and some acoustic fibreglass should give me a 10% apparent increase in volume. Just trying to decide on connections and wondering if I should wait and get a Speakon socket as well as using banana terminals.
I'll probably get a Yamaha PX3 to drive it in the short term or maybe the PX5.

It isn't pretty but I'm more interested in performance in what is, after all, just a $60 box and driver.
When I turn the box over after the glue dries I'll add more FG to the inside of the box, the yellow Acoustic stuff I couldn't get a 2-pole Speakon socket so I've just gone with the banana sockets, I may add a little anti-short block between them tho
