[QUOTE="n2audio, post: 6252177, member: 540940"] FWIW - your sealed box will work fine temporarily. The rec sealed box is 1.0, but it plots ok in 1.75, just use some caution when cranking it - being that much bigger than recs could reduce it's power handling some. Or your could secure something inside the box to take up some space. You lose some output with a sealed box, but you gain it at the upper end of the sub spectrum, especially vs a low tuned ported box. They both have pro's and con's. I recently went to ported from sealed because I went from two 12's to one and wanted to retain as much output as possible. I've had good results with both. MVW - is "frequency response" not a BIG component of sound? If two speakers have a different frequency response based on their enclosure is that not "sounding different"? You're taking the amp challenge basically verbatim and applying it to enclosures. I've been experimenting with ported enclosures for less than a year, but I know enough to know a well designed ported enclosure can and will usually plot as flat or flatter than a sealed design. The ixl12 is pre-loaded in win isd pro. Look at the ideal closed plot vs the ideal ported plot and tell me which one is flatter. [/QUOTE]
