I would like a little bit of help from the people here that are more experienced than myself. I built a box for 2 Polk MM1040 subs a month or so ago. I followed the recommendations on Polks website for the box dimensions, but am not happy with the results. I think the box is too small. I plugged the dimensions into the box calc on the RE website, and the volume turns out to be slightly less than what Polk recommends, not even accounting for displacement. The subs sound really good on some songs, but seem to lack range and have kind of a boomy sound. I was wondering if someone here had experience with these subs in ported enclosures, or could tell me what size enclosure might be more appropriate for the subs. Thanks in advance for any help.
