Thanks for delivering the fail, bro. Debating is a healthy part of life. You're just being immature.
BTW, a 5x7 paper cone woofer sounds like a 5x7 paper cone woofer. A "10" sounds like a "10". Sound reproduction of said woofers is dictated by what enclosure they are in. Good job.

haha ok..im saying that every single woofer has an enclosure or 2 or 3 or 4 for that matter that they will function and sound the best..wether its sealed ,ported,bandpass,or whatever..if you tune a box too high or too low for a woofer ,it has the potential to not perform,or not sound the way it should,or just blow the fuck up..hence the "WRONG" enclosure. and for the record,i totally agree that debating is a healthy part of life..im not too sure how anyone is being immature,but you sure did get defensive for no reason.and you are more than wrong about a 5x7 sounding life a 5x7 and a 10 sounding like a 10.. sure in a little sealed box they might sound like what they are..ive built all sorts of enclosures for all sorts of speakers and gotten tons of good and bad results..so as far as bringing the fail goes,im not sure what part you have trouble with understanding..but i know i have been installing for going on 11 years and have done tons of builds and tons of research..so im not spouting off bullshit information..im credible,ask around if you dont know,,and fyi,you are more than entitled to your opinion,and too debate what you want..im not gonna fight about what you or i think is correct.
Well said...And quite calmly too.. reps.
very rare for me by the way
nice, and understandable

What is tuning a box too high, and tuning too low?
And how am I wrong about a 5x7 sounding like a 5x7, and a 10 sounding like a ten? You might have misinterpreted my previous post. When I put a 12'' sub in my car, it is going to sound like a 12'' sub. It will vary in spl and frequency response depending on it's enclosure. We could honestly bring physics into the equation to show that a woofer is doing the same amount of work, no matter what enclosure it is in.
Most people think ported is way louder than sealed. In reality, if you took the average SPL through a range of frequencies, 20hz-80hz, sealed might be louder in that case. Ported boxes usually contain a strong peak which cause most listeners to think of as louder.
I have been into this shit for about two years. I guess that means you're more than 5 times more experienced and knowledgeable than I am, right? That being said, I am not trying to say I am "smarter" than you or anything, I am just not sure why we have to justify out knowledge through "x" amount of years.
what is tuning a box too high or too low?..well its relative depending on the woofer..if you send 1000 watts to a woofer in a ported enclosure tuned at 30 hertz,some woofers might not perform the way they would at 38 hertz,or 45 hertz..every woofer has their own footprint and an enclosure where they are the most efficient and perform the greatest..you could have a port volume that is too large or too small(port tune) and make your woofer completely useless..im not saying that every box,every size,every port is "wrong" for every sub..im simply saying each woofer has a box or a port that they perform the absolute best in.any wrong calculation in box size or port length or overall port volume can make or "break" a woofer physically or audibly
To expand, All subs have a natural Frequency at which they are most efficient. If a port is tuned above that frequency (too short) or below that frequency (too long) it wont be as effecient as tuning the port to that woofer's optimal tuning frequency.
As far as port area (size of opening), this is tuned to the box not the woofer (in most cases). Generally, optimal port area should be calculated (roughly) at 15-16 sq inches for each cubic foot of net box volume. Some woofers can vary a bit from these numbers, but generally, when using this formula you get a tuned ported box that has a wide frequency response from high pass cutoff to low pass rolloff.
When a ported box is tuned properly, it is ALWAYS louder than a sealed box. That said, the comment about across frequency range the summed SPL of a sealed box would be technically louder, which is great, but show me one competition series that rates SPL across the frequency range. The Ported boxes that beat hard at one frequency and then suck on the rest are the prefab, Best buy special boxes. these are made to pound at (give or take) 40hz, which is where most hip hop songs play. A truly tuned ported box with the right matched sub or subs will beat across any USEABLE frequency range (30hz- about 50-60 hz). Not trying to argue with anyone, just throwing out some facts.
As far as Bad Apples work, dude does sick shit. Thats coming from another Shop owner with 15+ years experience in the industry.

i wasnt justifying anything,i was simply stating in those 11 years i have done a ton of boxes and research to back up my knowledge.
In my 1.5 years of fun I have done tons of boxes(15-20) and research to back up my knowledge.
you are all about gettin defensive.im not gonna argue with you anymore
If you've ever heard a pair of DD 1508's (8-inch speaker) in a Ported box, you understand how an 8 can sound like a 12.
those dd 8s are decieving but they are one hell of an 8 i wish they made 9508s

I have sat in your SC300, if that is what your asking. I think there was a pair of dd 8s, vibe 3 way components, handful of vibe amps, and premier double din.
They didn't really compare to anything I have heard(single 12'') but I think it was cause it was in a trunk.
I have no doubt in my mind that a dd8 will out perform 12s out there. Just didn't really surprise me. I think they might have been in a truck box and that is probably why they didn't blow my mind.

Yeah, we did that setup really just for quality listening. Its hard with the sc300's trunk being sealed off from the car and having a gas tank inbetween. We had 4 of the 8's in an xterra hitting 148's on music at the windshield. They're nasty
My first real sub in my car was a RE8(I know I am an RE whore haha, I am trying to branch out). Blew my mind all the time. Never got the chance to meter it though. Not louder than my SE12 on close to the same power, but that is understandable.
