like I said, its the weight, heavier/dense the wood the better

Whatever plywood you use, you have to remember that although it is a manufactured product, it is made from layers of natural wood. Even if you buy similar quality boards there will be some variation between them.
Voids are caused because there are knots in natural wood and some of these fall out of the laminates before it is glued together. For this reason it is possible to find voids in any plywood. With an increased number of laminates for a given thickness board any single void will obviously be effectively smaller.

I get the impression that a lot of forum members use ply from the big DIY chains, so the original poster could always compare what he has bought to that which others are using.

Should be fine, ive got 12 HDs, some void free birch, some MDF, and some cheep ply, i cant tell the difference by liserning to them.  If your really botherd you can make the brace longer towards the fount.   As long as its wbp (waterproof) and not the stuff thats really cheep that d lamanates when it gets a bit damp i think you will be fine.

If these are your first build, then cheap ply will be ok. Any mistakes you make will only be cheap ones. Then you can always sell them on ebay, and remake them with void free ply.

3 things you have to think about
 
1. its a bass cab
 
2. is the voids 'buzzing' when you have some kick arse bass going through it
 
3. is the weight of the cab, you don't want it going walk about because its too light
 
I bet its 7 layer ply? too light

difficult to say - if you are going to build a cab with sh*te wood the HD is probabily going to be more rigid due to it's small size - all depends on whether you can sleep at night really... bringing a sub standard cab into the world - i don't know...Ouch

the hd15's dont have any big panels that will vibrate too much, and the cabs are not likely to take corner knocks as frequently as a 1850 horn.  youll probably be ok, though the resilience and aesthetic wont be as good as if you spent £40 per sheet.

Haha! I must have come across as a strong opinion style person. I'm not too fussed about whatever the wood is physically myself, as long as it is void free. It's subjective for me. But if your ply is like swiss cheese...
