most over-rated sub?

yeah it was an oscilliscope he judged whether or not the wave forms were in phase = cancellation.... they werent ....yet another thread taken off subject to trash my system

 
"because my 2 different sized subs with the right amps sound great, have a almost perfectly flat responce, and have no cancellation and miniscule total harmonic distortion" you can take my word for it untill i take some pictures of the oscilliscope with it all hooked up... i don't own the amps yet but i have tested the system with my buddies' amps and i allready know what it will sound like, what the oscilliscope reads, and roughly how to set the amps before i even drop them into the car... the resulting setup will/has looked great... have exellent sound quality, blow out my back window, and serve as a testimony that i have no consept of money" don't worry i'll have them within 3 months,and i'll post some readings... till then, you can leave my system alone... of course the POS they are resting in is certainly not their final resting place, that should chang by the end of the year
You are an imbicile.

An Oscilliscope WILL NOT prove anything for you. It will show a waveform output by the AMPLIFIER... that's it. (Useable measurable purposes.)

i failed english a year you'll have to excuse me... but i was saying that i know what my finished system does because my buddy ,who deals jl and sold me the subs, let me hook up 2 of his amps and we did a reading when i bought them... but i don't have the amps right now and never thought i'd have to prove that my system sounds good without letting people hear it... (newwer to the forum thing) so i don't have any pictures to prove the reading and can't get them untill i buy the amps myself so untill then just leave my system alone
A reading of what. Nothing you've mentioned qualifies as a quantitative measurement. Pictures will prove NOTHING.

wow ok? don't u understand i love the system and would preffer it to a same sub setup? when i post the readings then you can say it sucks
You really don't get it. NO QUANTITIVE MEASUREMENTS CAN BE TAKEN.

lies? simple math an 18 has an area of 254.34 square inches
a 13 has an area of 132.665 square inches, 2 13's have 265.33 square inches

so 2 13's have only about 4%more suface area than an 18
Here's a lesson for ya douchefeg. The measurement for this "surface area" you call it, is called cone area, or specifically Effective Piston Area (Sd).

 

The Sd of a JL13 woofer is 107.35 square inches.

The Sd of a standard 12spoke 18" woofer is 187.55 square inches.

This would yeild 14% more Sd.

Though, you must take into account Linear Excursion (xmax) as well. To give the total effective displacement of the speaker.

just my opinion... but i've found that re's aren't as consistant in production as the w3's, (less dependable) pehaps a reason for higher cost but still just selling a name
You opinion does not count, because you are a moron.

i would've stayed on the subject but someone said... "how can i judge subs with 2 sizes in the car", and i was trying to explain that the 2 size sub setup works great but i can't prove it right now since i don't have the amps to do a o scope reading" but the multisize sub setup can give you better SQ than a same size sub setup if you do it right, an as far as output... ummm i probly won't have a back window too long
Two different sized subwoofers are superfluous. It is absolutely ridiculous to do, since any size is able to cover nearly the same frequency range.

If anything, add dedicated midbass.

as far as multi size sub setups... is the difference worth the price and work required? probly not... but it shure looks good sounds great and you can hear it coming from another state... besides like i said i got no concept of money... it was a challenge, a challenge that i succeded in, now i just have to succede in passing english and getting 1600 bucks fer the amps lol

we're not trashing your system. if you like it good for you. what i'm trashing is your ideals behind it. they don't make sense and me and the other 17 people bashing you know it.

lol as far as my sx. it's now an RE/FI hybrind dual 0.7 ohm coils, three stiff spiders and btl sized leads. and is now being pushed by and rd audio 2200.1d. since i don't have the amp yet and the sub is still being broken in i'll get pics and vids laters.

 
I run a single 12 and a 6.5 sharing all the same frequencies in my room and it sounds beautiful.

I am going to get some numbers across 30-120hz, which is where they are crossed. The 6.5 is also acting as a midbass.

 
idealy you would have one speaker that would cover the entire hearing range. since that isn't usually possible you have to break it up in sections. I.E. sub(s) , mids, highs. the less you can break them up the better you will be. know what i mean. so having tweeters and mids and mid basses and 10"s and 12" and 15"s isn't neccesary. and as far as inverting the sub the change the phase, you can always wire it out of phase or whatever you need, or you can usually change this on the fly with any deck that has a sub out put. i know my last three decks had a sub phase control on them.
i could've just as easily changed the phase but the box for the 13 was a little short on airspace so it made more sence to invert it

 
I don't get why you guys are so confused by cotjones, if anything it makes me think all of you are retarded if it's so hard to read what he's trying to do, not that hard.

Plus it is better to have subs play different frequencies, a single subwoofer handling lets say each frequency from 50 - 100 won't sound as good as a sub that plays just a single 50hz tone, his reasoning for multiple subs is also so each sub does less work, not just that it covers different portions of the spectrum...

although, yeah an 8 and a 15 can cover pretty much the same scale of a spectrum, but what will handle 25 hz better, a well made 15 or a well made 8?

You can disagree with me if you want, fine, but by personal experiences the 15 is usually able to handle 25 hz much more loudly than an 8, not necessarily more clarity, but easily more loudly.

The only real problem I see with cot jones's setup is it takes forever to tune, and because of the accuracy needed in sub placement, box design, tuning etc, it simply doesn't really seem worth it, it's much easier to do such a cover of the spectrum with tweeters and midranges than subwoofers.

As for over rated subs:

Sony Xplod, kids go crazy for 900 WATTS OMFG

Then audiobahn

I can't honestly say type Rs are overrated, since most kids who go crazy about type Rs, don't know what they're talking about in the first place, so that's an unfair judgement

then again, neither do those who deal with xplods or audiobahn, but those two companies aren't worthy enough for knowledge of the product to be important, if you own em, you're probably a moron.

wat the **** is your problem? 90% of what you just said here is ignorant insults that anyone with a brain or half a shred of maturity would sneer at.... all the ideas you presented couldv'e easilly been stated without comments like...

you really think you're a god of the internet don't you? well i'm sry my personal prefference dosen't live up to your will oh informed and wise one... i'll make shure never to say anything again for fear your wrath might strike me down........ cut down on the shit talk.... up the audio discusion, get a life, and let your balls drop, you can't stay a pwning 12 year old forever

I'm not a fan of ng's trash talking either man, but he made a lot of valid points which you promptly ignored. Re-read his post and realize how much trash you just spewed in this thread.

 
the only reason a sing 15 is going to play a lower not luder is because of the surface area. get a single 15 and the equivelant amount of surface area of 8" and they should play just as low. as long as the tuning is low and what not. i'm sure some 8"s can get low to.

thank you //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif you are one of the few with a brain
