Here you go two of the fane's in a 40l cab will do this with a fully rated amp driving 450W into the cab. That's a couple of db louder than most 12's. What it will need is a decent sized port as the amount of air that port will be moving at full power will be considerable. I've looked at using a 110mm soil pipe inside diameter 108mm 11.15mm longas a decent compromise. I'd be rear mounting the port so as not to weaken the front baffle too much.

 

 

If the port is 11.15mm long, surely that means it will be shorter than the thickness of the cab (assuming 12mm ply).

I see that many people round the edges of the cab.

 

Is there a good reason for this please? Perhaps for the mottled finish or because the plastic corners assume so?

 

If so what's the recommended radii? 5mm?  12mm? Or just to take edge off?

 

Thanks.

I assume it’s to lessen the impact to your fingers when you walk in to some immovable object loading in.  I’ve got a hell of a lump on my little finger where I bashed it on a hand rail carrying a tumble dryer - if only it had rounded edges…

To stop chipping and make it more pleasant to handle. Very easy with a router.

 

Also paint won't take well on sharp corners. 

 

12mm is good.

Fair enough...
