The Parthenon still kicks it's ass though, no doubt about that.

22" is a toy in comparison.

That generates reference level (121 dB SPL) output at 20 Hz, when sitting naked in a room - no room gain, no baffle, no box required.

Simply unreal.

Yes but what does it actually sound like and how much does it cost?

 
I'd put it on it's back and put a possum on the face of the woofer... and then I'd wash my hands because possums are disgusting.
 
I don't understand this? Is MTX good stuff or garbage? I've seen their subs for $20, but then I've seen them sold at higher end car audio places and sen them in Murcielagos. I don't get it.

Why is that?

a vented enclosure if tuned correctly is GUARANTEED to hit up to 3db harder than a sealed enclosure. A bandpass enclosure can hit almost as hard as a vented enclosure but can only do it at one certain frequency, so in the rest of the spectrum, it plummets. At my brother's shop, he has a display where he shows the customers 2 subs in a sealed enclosure, and 1 sub(the same exact brand/model) in a vented enclosure. Each sub gets 400 watts RMS and of course multiply that by 2 for the dual enclosure. The single sub literally humiliates the dual setup, all because of the enclosure. Another advantage to a vented enclosure, u can have it tuned to different frequencies, if u want deep bass, hard hitting bass, or both. Pick up pioneer's new subwoofer catalog at ur local stereo shop and in the back of the catalog they have graphs of the 3 different types of enclosures(u'll see that vented/ported enclosures humiliate the other 2 types) and u'll see a better explanation of what i was talking about.

hope that helps

A vented encosure can produce 20+db more output at certain frequencies but that wasn't the point. The point is that alot of drivers are made for sealed boxes and marketed as if they can be used in both sealed and vented. They sound great in a sealed box but get a little boomy and nasty sounding in a vented box.

I prefer that the driver is actually designed for a vented encloure and yet so few exist on the market mainly because this would cost more to do.

Ever been to a competition? If so, did you happen to get a glance of what boxes they use? They use vented enclosures. I bet you can make the crappiest subs hit very hard in a vented box. Everything works well in a vented enclosure. Through experience, I should know this. Subs dont start sounding nasty in a vented box. I had cheap 40 dollar Q Power subs hit very hard and sounded very good in a vented box. They sounded better in the vented box than the band pass box they came with. We had just one Earthquake DB sub in a vented box. That one 12'' sub was hitting very hard for just one sub. It actually tickled your ears!

Have you ever heard of the company Pro Box? They make some of the best custom boxes you can get. If you take a look at Pro Boxes' best boxes, guess what kind of enclosures they are? Vented boxes. The MTX Sledgehammers custom box is a vented box. Pro Box also makes enclosures for the Solobarics. What kind of enclosure are they? Vented of course.

I was asking about the "For prefabricated boxes" part. I didn't need a fricking essay.

I posted a reply to your question earlier. I explained why a prefabricated vented box is the way to go if you do not want to pay more to get a custom built box. Custom built boxes of course will be better because they are built to the exact specs of the sub, but not much people are willing to spend a lot of money for a box.

THats not true, i've seen plenty of sealed systems in competition.

Sealed is the way to go for me, but i don't listen to rap crap - so i want my bass to be tight.
 
Sure, you may have seen sealed boxes at competions, but they are still not recommended for competitions. Kicker recommends vented enclosures, MTX recommends vented enclosures, Pioneer recommends vented enclosures, Earthquake recommends vented enclosures, and so does MB Quart. We built a custom built box for 2 of the newest 12'' Kicker Solo Baric L7's in a tiny civic. It was a vented enclosure. We were listening to Metal Health by Quiet Riot, and those damn Kickers were hitting EXTREMELY hard!!! They were hitting so hard, we made sure the guy doesnt go driving around bassing out in full blast or he would go deaf!

Some people prefer sealed, but through personal experience and what these MOST companies recommend, I would like to get the best sound possible out of my subs, and vented IMO is the way to go.

Vented is louder and produces more output from the port frequency and up. Below the port frequency it falls pretty rapidly. So YES vented is louder but unless you use a driver that was actually designed for a vented enclosure you probably won't get the best bass quality.

I love a good vented subwoofer but sadly I see to many people using subwoofers that would work best in sealed boxes.

If you ever get a chance listen to this subwoofer it's my reference point: http://www.wilsonaudio.com/products/xs/index.html

That thing is way overpriced.
 
A real test of a woofer is to be able to reproduce a SQUARE wave with low distortion. It's currently not possible as the moving cone has to have zero mass. Well it is possible to acheive, but a driver in a conventional sense is not going to...

That said, a trip to the Cascades a few years ago watching a laser system fire that created wavefronts that blasted the bark from huge trees over 30 meters away and the sound pressure level was calculated to be over 245 dB as no microphone could measure it - was impressive. Supposedly, this setup can do square wave and produce shock waves that can kill any living thing instantly. I don't know that much about it but that it exists and I want it. 🙂

Cheers!
