justinschmidt Posted April 10, 2012 Author Report Share Posted April 10, 2012 (edited) is it really only .3 for two t1's? Thanks for your help, Where should the port be located and what direction should the subs fire? I'll sketch something up on my ipad once I have that information. Also, there would be two measurements for the port correct?, any idea what those would be? Also, that's only 3.91 cuft after port volume and displacement, that's enough to maximize the potential of these t1's?

justinschmidt Posted April 14, 2012 Author Report Share Posted April 14, 2012 (edited) Can somebody run this through the calculator for me and tell me what they get? I have the calculator but I don't understand how to calculate the port yet. L = 35" x W = 18" x H = 30" plus the port info is posted in the sketch. EDIT: also rockford lists the woofer displacement as follows Woofer Displacement (in): 0.151 cu. ft. x2 of course.

Joe X Posted April 14, 2012 Report Share Posted April 14, 2012 Ok I will say that this is a unusual box for a hatchback but if that's what you want then here it is, based on RF suggested net volume and 35 Hz tuning: Enclosure Specifications: Fb = 35.074 Hz Vb = 4.538 ft^3 External Height = 30 in External Width = 29 in External Depth = 18 in Port Height = 3 1/8 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: 2 x Front & Back (3 parts) = 29 x 30 Left & Right Sides = 15 3/4 x 28 1/2 Top & Bottom = 29 x 15 3/4 L Port Internal Assembly Parts: Front to Back = 12 5/8 x 27 1/2 Extension = 14 1/4 x 27 1/2 Quote Link to comment Share on other sites More sharing options...
