And, if you're going to make one of those swoopy, curved-surface type horns, then building your own 'ply' from thin pieces of wood/hdf and strong glue will give you a pretty good start.
I'm trying to locate a local business that makes 'moulded ply' at a reasonable price so that I don't have to do this. It makes the curved ares very strong and they don't require much bracing - I used a childrens' bench (in moulded ply) to build a small TL and this worked quite well.

The consensus of most (but do search to confirm it) is that there are problems associated with solid wood that do not generally make it good for speaker building. Unless it's stable (I think Stradivarius used very old, slow grown wood from the previous "little ice age", good Japanese flute makers use bamboo that's been aging for 100 years), then chances are that it may split or develop cracks during periods of high and low humidity. Depending on the type of wood, it tends to 'sing' or reverberate at various frequencies, whereas the various fibreboards and plys are more 'dead' - which is better for a speaker to reproduce recorded music.
But there's no consensus on this, and there are more threads out there to read. The simplest idea is to get some cheap wood (ply or MDF), cut it carefully (don't breath in any wood dust) and build your first speaker. The trials and tribulatiojns you go through will mostly be with design/crossover/damping/driver parts. If you reasonably happy with the result, you can always build another box and transfer over the parts - that's the easy bit...
