[QUOTE="jonathanengr1, post: 7350732, member: 633698"] Hispls--just saw your post. I'm not sure if I've specifically said it, but you hit on a good point. I'm not looking for loudness here--I just want some good-sounding decent-volume bass to blend (or maybe outdo a LITTLE) the rest of my stereo. Trust me--as loud as those subs were playing at mid and high levels, I could definitely do with less bass... especially if the solution would give me a good, clean low-end. I actually thought about taking an hour or so to build a 1.5 cf sealed box and trying it out. If it doesn't work, then bore a hole and put in a round vent. I noticed they have "tunable" vents out there (can slide to lengthen or shorten)--are these any good? My main concern about the sealed box is size. Please don't everyone bash me because I have VERY little experience compared to you guys, but I have never seen a sub that has rec'd sizes for ported and sealed enclosures that are the same size. Most of the time the ported enclosure size is almost double the sealed enclosure size. I don't want to toss these into a ported enclosure the wrong size where they'll sound horrid when they might actually be *perfect* for what I'm looking for at the "right" size. How can I determine what the "right" sealed enclosure size would be? Honestly--they guy I spoke with at DD who told me "the same size " reeeeeeally seemed to be pulling that one our of his ear. Lastly, when you say the sub might sound terrible in a sealed enclosure, what do you mean? That it won't be as efficient and then quieter than ported, or that it might really have terrible SQ? I have an SVS Ultra-13 subwoofer for my home theater system, and it is one amazing piece of low-end technology. It is triple-ported, and comes with baffles to "tune" it. Despite its being ported, it is never, ever, ever, ever boomy--even with the baffles completely removed. It just sounds amazingly good, and at loud volumes almost compares to a good massage :-) You said that DD designed the subs for a specific use, so surely they designed it to sound good in their box design and not distort horribly... so confusing!
