hook'em Posted August 6, 2012 Report Share Posted August 6, 2012 That is definitely not going to work. WIth that box design your box is tuned to about 77Hz and will sound like complete crap. Quote Link to comment Share on other sites More sharing options...

WIth that box design your box is tuned to about 77Hz and will sound like complete crap. huh? how did you get a tuning when he just posted external dimensions?

Joe X Posted August 6, 2012 Report Share Posted August 6, 2012 Welcome to the forums.Here is a suggestion for a box: Enclosure Specifications: Fb = 37 Hz Vb = 0.88 ft^3 External Height = 12 in External Width = 20 in External Depth = 14 in Port Width = 1 5/8 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 17 5/8 x 10 1/2 Back = 20 x 10 1/2 Left & Right Sides: Side 1 = 12 1/2 x 10 1/2 Side 2 = 13 1/4 x 10 1/2 Top & Bottom = 20 x 14 L Port Internal Assembly Parts: Front to Back = 10 7/8 x 10 1/2 Extension = 14 1/2 x 10 1/2 Extension 2 = 3 1/16 x 10 1/2 Let me know any questions.
