I am looking to build a new subwoofer. Something easy to build.\nRoom is sized about 20" x 15". Crown XLS 1500 or 2002 amps.\nUsage is Music and Movies, with Music as higher priority.\n\nI am currently looking at these two drivers.\n\nDayton Audio RSS390HF-4 15"\nDayton Audio RSS390HO-4 15"\n\nWhich would be a better option? Or is there something else i should look out for?\nShould I go sealed or ported? 2ft x 2ft box or smaller would be great (A bit flexible on this).
