When designing speaker boxes, how important is it to take in consideration the possibility of standing waves between parallel box sides? It seems JBL sometimes takes steps to minimize them through a non-parallel box side design (f.e. 250ti, Array-series etc) and other times they don't (f.e most of the studiomonitors). Is dampening material like wool or fiberglass sufficient enough to handle this problem or is there just one way to go: designing speakers without parallel walls?
Thankfull for any info on this,
