Built a box …birch pine 3/4 ,and made the mistake of a much larger enclosure than needed ,(Sundown v.2 12 d2 ) with that said 2.6 cu ft was too much so I added wood in the corners small cut strips ,then added larger pieces on the inside walls port walls side wall top and bottom and if math is right I’m at 2.2 now and it drops low for sure ,my question is should I go smaller .?spec is 1.75 and I might as well build another one to achieve this .Will it damage speaker overtime? It sounds amazing. Also My port tuning may be a little off ,I have overall 25 inches one 11 another 14 x15.5 3-4 ….2.5 inches wide slot. Looking for expert advice here . Thankyou
