hayden55 Posted January 2, 2013 Report Share Posted January 2, 2013 I was wondering if someone could help me design a box for a R8 subwoofer? The engineer over at alpine stated that a .55 cubic foot box would be best for ported boxes. I dont really know what to tune the box tune except for maybe 30Hz? I plan to run the subwoofer off of a rockford fosgate r250-1d rated at 295w rms, and a harrison labs fmod 30hz inline rca subsonic filter. It says that the subwoofer can play all the way down to 28hz on its frequency response. All i know is that i want a .55 cubic foot slot ported box that can play really low. 2006 Ford Ranger XLT 3.0l-Rockford Fosgate 6x8s 3-ways- Sundown Audio SA-8- 3.64ft3 tline box in naked mdf- Kicker zx750.1- 0/1 Gauge wires- Pioneer head unit stuff to come:16 steve meade 18's7 rockford fosgate t15000bdcpa fleet of escaladeslol jk new car?

Joe X Posted January 2, 2013 Report Share Posted January 2, 2013 Ok here is a suggestion: Enclosure Specifications: Fb = 35 Hz Vb = 0.6 ft^3 External Height = 10 in External Width = 20 in External Depth = 11 in Port Width = 1 1/8 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front & Back = 20 x 10 Left & Right Sides = 9 1/2 x 8 1/2 Top & Bottom = 20 x 9 1/2 L Port Internal Assembly Parts: Front to Back = 8 3/8 x 8 1/2 Extension = 15 1/2 x 8 1/2 Extension 2 = 3 3/8 x 8 1/2 Assembly guide (generic dimensions): Link to comment Share on other sites More sharing options...
