Re: Ahhh Houston, we have a problem....
I don't think you would have any unusual issues with bamboo, but I've not tried that.
I discovered the misfit issue after I had everything else done...... crossover, binding post connections, insulation back in. I had to remove all of that before I could try enlarging the woofer cutout. I hope I at least saved you the hassle of that! Fortunately I only had the 1st speaker assembled like that.
