As I keep progressing, I'm encountering new challenges. I'm posting them here as this thread has documented the build of all the speakers that I'm building too. Hope OP doesn't mind my posting queries here.
I've noted that a few members have made baffle twice as thick as the rest of the box by affixing two 19mm sheets which can loosely be termed as double baffle IMHO. In India, we get only 18 mm sheets. Many members of that Indian group buy have made X-LS speakers with double baffle which I personally consider an overkill. However, since the X-SLS is much longer, I found the double baffle to be a great idea and hence have fabricated the same by affixing two 18 mm sheets. (I've also remembered to do some chamfering of the inner sheet.)
Now my query is, does this double baffle thingy is necessary for the X-CS and A/V 1RS too or would it be an overkill (especially for the A/V 1RS) As per my perception, since the X-CS has two mid-woofers, double baffle may be of some relevance.
