[QUOTE="Joe89, post: 7692540, member: 583644"] Thanks Buck! I am going to try the same thing. I'd like to build my enclosure tonight but I am having a hard time figuring out what to do... I am going to use 4 12" RD Classics until I get some beefier subs for the 4kw. I've heard these drivers do best with sealed enclosures, and if they are ported, with a smaller-than-usual port area. RD Classic 12" Specs: fs: 38.6hz qes: .4 (ebp=96.5) qts: .365 qms: 4.24 rms: 12.07 cms: 0.0803 MM/N mms: 210 G BL: 20.85TM vas: 34.7 xmax: 13mm xcoil: 36mm Now, on to the WinISD graphs... [URL="http://imageshack.us/photo/my-images/24/freqresponsegraphsclass.jpg/"][IMG]http://img24.imageshack.us/img24/4512/freqresponsegraphsclass.jpg[/IMG][/URL] Blue: 4ft3 rear, 5 ft3 ported section. 45hz tuning. Teal: 4ft3 rear, 8ft3 ported section. 45hz tuning. Green: 8ft3 ported, 38hz tuning. The port is set to be a ~288sq in slot port for the 2 bandpasses. Obviously I want loud but its going to be a daily so I want lows and highs! These graphs look really ugly. I am thinking I will build the port separate so that I can shorten it if need be. Any thoughts? Advice? What enclosure specs should I try first? [/QUOTE]
