  12. I have a question for the sub box building experts.  Will the 
  13. response of a ported box remain unchanged if the dimensions are
  14. changed?
  15.  
  16. To be more specific,  i have a ported box which has an volume of 
  17. 2.5 cubic ft.  It is made of 3/4"  MDF, and has a 4"x6.9" port. 
  18. The driver is a single 12".  This box (to me) sounds great, hence
  19. i want the retain the same sound characteristics.
  20.  
  21. I need to build a box which better conforms to my trunk, thereby 
  22. using the space that i have better.  If i build another box using
  23. the same driver,same port size,same building materials and give the
  24. box the same volume, but change the dimensions...
  25.  
  26.     Will it sound the same???
  27.  
  28. I'd appreciate any help, thanks,
