I am looking for a good woofer witch is cheap and will perform well in small boxes... I was considering a vented design and I would like to know if you guys have any ideas, as I am not experienced with what the Theile/Small Parameters mean. The driver has to be less then $100.00 USD and I prefer a poly cone. Any ideas?
Thanks,
Slice
p.s. where can i find out what the Theile/Small Parameters mean?

I have a sealed box with a standard 10'' Kenwood in my car and there is plenty of bass. Michel Donato (Jazz) and his bass helps a lot to loosen my screws...
subs
my opinions :
cerwin vega
kenwood is okish apparently
sony is ok i heard. Personaly i cant say but cerwin vega has a good rep.
Fs=resonance freq. this is the lowest note Possible that the speaker will play in the correct box(below resonance the speaker wil distort more,30hz is probably ok for most music.)
Q=quality factor,damping factor.lower usualy better(more control)
eg Q=0.33
Excursion-for a 10inch possibly 7mm is ok.
the more excursion the louder it can play ,in theory.
efficiency --
90db/1watt is good for a 10inch sub.
compared to a 87db/1watt sub, the 90db/1watt sub will need only half the power.(in theory)
ported boxes are harder cos u have to tune them reasonbly accurately.use winISD www.linearteam.org
or just use manufacturers recomended box

this from an employee of Jo-Di's car audio
Hi I've been working at Jo-Di's car audio store based in Connecticut for about 4 months now and I think your best bet is something like the Autotek SS104 whick you can pick up at www.caraudioexpert.com for $70. It has a ten inch cone and 40 mm surround. Yes you have it right it is a high exscursion woofer and while produce lots of big and move monterous air. If I also may sujest going to your local car audio dealership and buying it from them if this isn't a problem. They can help you with many questions.
I also have a few questions why you want to use a ported box. What kind music do you listen to mainly? A ported box while resonate a constant tone whick will be heard when ever you play music. A non ported box is more geared towards fast clean response like jazz or even heavy metal and a bandpass box is mainly for rap and possible some funk with really loud lows. so you have choices.

What?!
Ive had a lot of experience with ported boxes, and they dont do this. They cant. Its impossible.
A ported box is tuned to a certain frequency that just determines how the box will support the speakers front wave with the rear one. It doesnt all of a sudden create its own sine wave out of no where.
I do agree with your box suggestions, however. But a good ported box will still play music very well. I myself dont see the need, as cabin gain will make up for a large amount of the sealed box rolloff.
This is not true. I have had nothing but problems with their drivers and their company. For around the same price, Infinity Reference subs are much much better.
I like Kicker CompVR's if your going under $100. They can handle 400W RMS, and sound very nice in a proper cabinet. The only drawback is they like perticularly large ones. A .707 alignment for a 12" is 4.6 cubes. But. if you have the space, you wont be dissapointed in anyway.

>> ported box while resonate a constant tone whick will be >>heard when ever you play music.
no sub does this.that is completely untrue.
a decent ported box sounds great and goes lower than sealed boxes..
bad designed ones are crap
sealed boxes have lower group delay and nicer transients.better sound.
in a car thumping 50hz tones you dont need audiophile hifi quality sound.
-so porteds are fine u just have to tune them.
bandpass are tricky.
use winISD or use manufacturers boxes.-they are often boomy and honky but loud.
