Looks nice, just a little clean up and just the raft out behind the speaker.
I have a recently revised version of the code that beings the crossbars deep to avoid a raft:

module speakerbars()
{
for(y=[87:10:270])
{
translate([50,y,0])
cube([217,3,16.8]);
}

for(x=[77:10:270])
{
translate([x,85,0])
cube([3,180,16.8]);
}

}
