[quote=ObsceneJesster;20960542]I am not doubting one bit that ported subs can be everybit as accurate as sealed designs. I understand that there are people here who build, design and buy multiple $2000 subwoofers. Maybe I should have made myself clear in the begining but
my comment was more geared towards those who have a $500 ported subwoofer that think it can extend down to 18Hz while still being tight and accurate. Sorry but its just not happening.
Extension is not proportional to displacement. A rythmik FV12 will extend to 16hz and sound tight and accurate. It won't displace a ton of air (high SPL at low frequency) but four
of them will.
Yes, I do still have the Emotiva X-Ref 10 but it will be on its way back once I receive the shipping label included with the X-Ref 12 I just purchased. Some extra money came up and I figured another $100 wasnt much at all for 2 more inches and twice as much power. Im just glad Emotiva doesn't charge for shipping as im sure its not cheap shipping subs back and forth.
Speaking of 18hz, the emotivas don't even hit 30hz adequately....
You can't just throw watts at sealed subs; you still inevitably hit their excursion limitations, whereas a vent actually reduces excursion near its tuning point..
I was simply stating that the movie sounded great and that a sealed sub may have had something to do with it according to some research I have done.
Your sealed Emotiva sub that has no bass below 35hz? I watched this movie and just about all of the meaningful bass seemed to be in the 15 to 25hz region.
I didn't really think people who prefered ported subs would take it to heart.
I neither took anything to heart, nor do I prefer ported subs. It's irritating though, when people make uneducated statements
I happen to think (if done correctly) bass from a sealed cabinet sounds cleaner.
Are you even able to prove that you can identify a "correct" sealed cabinet vs a well designed ported cabinet, properly set up?
Another notion I was trying to put to rest was people thinking just because a sub is ported, it can get lower. This fact does hold true, only if however, the same exact amplifier rated for the same wattage was running both. This is typically why you see decent companies putting two, three and four times the RMS wattage in their sealed offerings over their ported counterparts.
As I said earlier, watts aren't the only limitation at low frequency. Raw displacement is. I run sealed sub, but I would never run a sealed 12" sub, period. 15s, only if I had around six of em. Sealed 18s, only if I had two to six. At the $600 price point, the limited displacement of 10" and 12" woofers lends itself a lot better to vented subs.
