I agree. The good news for the OP is that the FV-15 and the VTF-15h are BOTH good subs. But for somebody to extrapolate from the GTG that the Rhythmik is somehow superior is beyond me. It also means they must have skipped reading the conclusion:
"The A7s-450 and 18.1 are spl monsters. They're pretty much a tie in that department. The 18.1 to both Ethan and I does sound better than the s450. It just sounds cleaner and tighter. The s450 still sounds very good, not muddy at all. Its just once you've heard both, its clear the 18.1 sounds better. And so does the Empire, it is also a little monster. (little next to these guys) We'd put its sound quality on par with the CS18.1, although it has its own distinct sound so some of you may prefer one over the other. It was only down 2db's compared to the 18" subs yet went down to 20hz with authority. It's nice to know that even without room gain the Empire can go down that low. Rythmik's FV15 is a ported sub that has the sound quality of a sealed - a high-end sealed sub. It amazed us how clean and tight the sound was - at very loud volumes. You would never guess it's a ported sub except for it's output down low. It went the deepest of any of the subs, which is to be expected, and made it's presence known on some material where the other subs didn't. Then there's the HSU. It tied with the Rythmik in sound quality over the other subs, and again these two had their own distinct sound so you might prefer one over the other. The Hsu had the least output average, but only by about 2.8db. Oddly enough it shook the couch more than any other sub. One of the things we loved about this sub besides its looks was that it never complained no matter how loud it went. An outstanding sub all around.
Ok so to sum up, yes all these subs have their own strengths and each one is amazing in its own way. So again, the whole point of posting our experience is to provide some insight - not to sway you one way or another, but to leave it up to you the reader to draw your own conclusions. Hopefully we've helped you out a little in that regard.
Thanks for reading!"
