rcardell Posted June 24, 2012 Report Share Posted June 24, 2012 I just got a pair of 15" american bass hd's and i can't figure out the subs displacement from this sheet. Can someone break this down in laymans terms to me. How much displacement per woofer do I need. My available box space is 17.5(h)x41(w)x22(d) Total airspace 7.50cuft. thank you thank you thank you.

8ight Posted June 25, 2012 Report Share Posted June 25, 2012 (edited) I'm not sure if that can be determined from the provided information or not but when I can't find the displacement of a driver when building a home theater speaker or monitor I measure with this method: Take the magnet diameter and the diameter of the CONE (not including the metal ring with mounting holes surrounding the driver) and imagine them as cylinders with a height equal to the subs mounting depth. Calculate the volume of each cylinder (v=(pi)r^2h) then take the volumes of both respective cylinders and average those figures. This helps to get an estimate close enough to build a box.

n8ball2013 Posted June 25, 2012 Report Share Posted June 25, 2012 This is the only thing I hate about american bass. Bob is still in the stone age and doesnt provide all the specs. At least they recently upgraded their website.
