Sound Quality is subjective.....you're going to get way to many "ideas" as to one thinks is SQ.

Yeah, I agree...WHOA is in order..//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Yes I know. And I want to hear these "ideas" That's why I'm asking for your definitions of a SQ sub. I stated what mine is. If some can lead me to a sub that does it great. If not no big deal.

This is the subwoofer section. I'm not talking about tuning a system. I want to know what people consider a SQ sub. I dont give a shit what other speakers your running. Even if your front stage is playing the sweetest music in the the history of car audio. If your sub hits and it sounds like your running over a bunch of dead cats that is not SQ to me.

But if you're listening to a recording of dead cats while it's hitting, yea...ya got'yer self a soundy Q woofer, thar.

I'd simply stop right about now before this becomes an even more gigantic cluster**** of ridiculousness. One could explain ALL DAY that SQ is NOT subjective, NOT relative, and NOT up for debate, but then you're simply wasting your time as no one wants to hear that. What makes people happy is when you tell them what they want to hear. Namely, that SQ is something they hear. WHO DOESN'T WANT TO HEAR SQ? (did i yell that loud enough?).

The response is one of the main keys for me... Some are sloppy, some are tight and right on top of the beats... That is one of the many things I look for.

It's a question that cannot be answered with a definitive answer. SQ is in the EAR of the beholder.....

It is not subjective. It is a concrete parameter that can be measured, see BL performance. The more linear a cone remains with the lest ammount of lateral movement through out all types of response (long, short, hard, soft, etc) the less distortion and erronous sound is produced and the more accurate it reproduces the sound, and that is measurable.

Now...whether you LIKE what you hear is a different matter and entirely subjective. If you think bass sounds better with a bit of distortion (as I've had people tell me) then that may sound better to you, but it doesn't mean that sub is performing as accurately as another.

You can think all day long that for your tastes, Sub A sounds better than Sub B, but that does not make it a better SQ sub if mechanically Sub B performs more accurately.

Then don't call it SQ. Just tell me a sub that is capable of running a sweep from 30 to 60Hz at a fairly smooth volume level

If that was the case, it would be unmeasurable. Can me measure ears? No, but we can measure sound and the qualities of it.

Maybe I should have been clear....SQ is subjective based on the indivdual tastes of said user......sorry for the confusion in my statement. LOL

So to everyone that says "SQ is reproducing the original recording"

Where do you hear this original recording, you were there when it was recorded? Or at the concert! How do you know exactly what something SHOULD sound like if there is no reference?

It's not like that.

Pure sound is just that, pure. It is the sound wave and nothing else, mainly no distortion. All Woofers have some level of Distortion. Some also"bloom" or "color" bass. In other words, when the coord or tone is played, you can clearly tell that signal is not being soley reproduced. It's also being "modified" by the subwoofer. This can be measured.

That is how "SQ" is determined. A sound wave has a certain number or cycles. It's not "80hz sound like this because that's what we think it truely sounds like." It has a physical and mathematical property, I.E. has a wave length. When a sub produces a tone that deviates from that parameter, it is not accurate.

Now, to my knowledge, no sub on earth is perfect. There are some are very, very close to being perfectly linear, and there are some that are close to mathematically symetrical (meaning the same ammount of non linnear cone movement) on both sides of the stroke...which translates to minimal distortion throughout the entire stroke.

Now, at the end of the day, this all may still leave you with two subs that to your ear sound identical and thus a moot point. My only point was to point out that that instance does not just simply dismiss that one has a better SQ performance wise.

But I also know Im not going to get a sub with a Fs of 22Hz to do what I want it to, I dont care who designs and builds the box.

Umm, what? Looking at one parameter of a driver can basically tell you nothing of what the driver can do. That's like looking at a Lotus Exige and telling me that because it has sub 300 horsepower that it won't be able to handle corners and straight line roads like you want it too... that makes no sense at all.

My current sub has a rated Fs of 24hz and in it's current enclosure, the new Fs is around 16hz or so and plays measurably flat from 18hz to ~70hz with a 4dB peak at 22hz and everything else is flat within about .1 dB. Tonality is great, punch and aggression is there, group delay is very low, and phasing with my front speakers is great.

Maybe I should have been clear....SQ is subjective based on the indivdual tastes of said user......sorry for the confusion in my statement. LOL

You're confusing "sound quality" with "sound preference" or "listening preference" when these terms are not the same thing. A sound quality speaker is not one that sounds good to everybody as that's never going to happen.
