I would like information as to the best alignment that would be good for lower volume usage (the kiddies need their sleep ). Would a sealed or vented box be better? Any drivers you would recommend as well? Would like as small a box as required for the WAF. Mainly looking to fill out the bottom-end on movies and classical music (50/50). I have Klipsch speakers all around and no subwoofer currently. Room is 20' by 14' by 8'. Thanks in advance for any advice.
