Can you provide some room placement details. I can't put these too far out in my room. Maybe 2' from the sidewalls, 1' from front wall. Do you think these with the subwoofer option would work for me?

Hi,
The Speakers themselves are already well over 1' deep and with the subs would need some room behind them to 'breathe".
If you need to place them very close to walls the best option may be to place the Crescendo main modules on stands.
As the crossover is very low you could build a mono "coffee table" style sub to go with a pair of stand-mounters. This could then be placed independently for best results, especially in smaller rooms this can be the better option.

I have some very interesting wood options here in Costa Rica (harvested only from trees that have fallen naturally). Would you recommend soft, medium or hard density? Thanks.
Hi,
I'd probably recommend a laminate, with hardwood outer skins and core of wood that is similar to spruce (so medium density I guess) with good internal damping and structural strength.
Maybe a 15mm thick core and 3 - 5mm thick hardwood skins.
For the Baffle (which needs to be CNC Routed or needs quite complex shaping) I'd probably use solid hardwood or void free Birch plywood.
Of course, this is all hypothetical, based on the "if you have access to the right woods and carpenters etc.".
BTW, for anyone not living in Costa Rica, the local building market usually has 15mm Pine Boards for Shelves. If you laminate them with 5mm Hardwood Plywood outer surfaces you get very similar results.

PS, I intend to use solid natural stone for my own Crescendo's (and yes - a natural tone coffee table sub), as I have a company nearby that can work this stuff and is quite reasonably priced.
