Wait 5 cubes TOTAL for two 15's? I thought that would be kinda low hehe. are you runnin 12's or 15's? I asked this question thinking 3 cubes each might be a little small //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
My limit of space is 7 cubes, and i want two enclosures (leaving 3.5 cubes for each sub)

Sorry, disregard my post. I have no experience with the 15 Type R's only 12's and thought you were trying to do (2) 12's in 3.5 cubes total giving each the factory recomended 1.75 each which is way too low IMO. Anyways good luck with building a box for both your 15 type R's //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
