Default Vented VS. Ported

I have a 12" Bazooka 200w RMS that I want to get an enclosure for.I would like to get a second woofer thats the same model but their pretty pricey so I'm thinking about just getting a 1 woofer enclosure.So what I want to know is,does anyone have a 1 woofer enclosure and if so whats your setup and how does it sound?Also is it better to get a vented enclosure or sealed?And what exactly is the difference in sound between the 2?

Im running a 10" JL w6 in a vented Box. IMO Vented Sounds better because it lets more air out then a Sealed Box. Def get a vented box it will beat much better

Which model sub do you have? http://www.sasbazooka.com/prod...s.asp

Why not just go with the factory recommendations? http://www.sasbazooka.com/tech...rrent

Quoted from crutchfield:

Sealed boxes: For deep, precise bass
A sealed box is an airtight enclosure housing your subwoofer. A sealed box is best for any music that demands tight, accurate bass. Expect flat response (not excessively boomy), deep bass extension, and excellent power handling. Since a sealed enclosure tends to require more power than a ported box, use an amplifier with ample wattage for optimum performance.

Ported boxes: For forceful bass
Ported boxes use a vent (called a port) to reinforce low bass response. You get more output than you would from a sealed box at any given amplifier wattage. Some people prefer the sound of ported boxes for rock, heavy metal, or any hard-driving music. Ported boxes can deliver deeper bass than sealed boxes, though they need to be much larger than sealed enclosures to accomplish that.

Bandpass boxes: Maximum slam
Bandpass boxes are a special type of ported box designed for maximum slam. The woofer is mounted inside a dual-chambered box (one chamber sealed, the other ported), with the sound waves emerging from the ported side. The sound that comes out of the port is extra loud within a narrow frequency range.

Because bandpass boxes are super efficient within that range, they tend to boom. Their aggressive sound is great for rap, reggae, and hard rock. Not all subwoofers work well in bandpass boxes, though; consult our product information or call one of our Advisors to be sure.

I guess you found the specs for the sub http://www.bazooka.com/pdf/current/EL10041204.pdf

It's gonna be hard to find one thats right. So build one IMO.

It will be impossible to get a pre-built box that is exactly right, unless it was built for the speaker you have, yes you can get one that is close, even one that sounds pretty "good" and mods can be made to get the best possible sound out of it, but at that point you may as well build your own.

The above assumes you know how to build a vented sub cabinet and have all the tools to do so, if not, buy a pre-built, although I would recommend a sealed box when buying pre-built, find a 1 cuft box, [gross internal volume] made with at least 3/4" MDF, use up the extra .07 cuft by installing bracing, [3/4"x3/4"x1" blocks] along the inside seams, every few inches or so, this will "use up" the extra volume and brace the box, making it stronger and more efficient [less loss to flex], run a bead of silicon into all the seams and "paint" the inside of the box with a wood sealer, [I use fiberglass resin] and you increase efficiency even more, [less loss to air leaks] SQ will also improve as will power handling
Beefing up a pre-built sealed box is easier then beefing up a pre-built vented box, or I should say it's easier to get good results. 94

So if I get a pre-built sealed box I should drill a port in it ot leave it sealed?

LOL. We're trying to tell you that 1.) If you want a ported box, have one built because finding one even close to specs is unlikely. 2.) A sealed box is easier to find pre-made for around 1cu. ft. of space(your sub takes .93); so if you find a 1cu. ft. sealed box.....before you install sub add some small wood braces to the inside of the box, it will make it stronger and reduce the 1cu. ft. of space to near .93cu. ft. which you need for your sub.

If you still want a ported box and don't want to spend a lot ask some friends or post a message on craigslist about it.

There are a number of free programs on the net that help you build a proper enclosure for your subwoofer. Winisd is one those programs, and best of all it's free! Go to the following link:

http://www.linearteam.dk

They have some tutorials and examples on the site aswell.

I personally used Winisd to design my ported enclosure and built it myself. It's definitely worth the effort!!!

Don't ever buy a ported enclosure that isn't built for a specific speaker. Never! A friend of mine bought a random ported enclosure- the wind noise was terrible and the sound quality left much to be desired.

I have one SVC Sony XS-L124P5B 380W RMS in the custom box with 2 ports. The amp is giving it 300W RMS. There's no wind noise and it sounds great. The response is very good (for example when listening to metal music with double bass kickers). Also for a single sub, compared to others I've heard, it's pretty loud. So yeah, if you have the time and motivation design a proper ported enclosure.

Closed enclosure is a whole other story- you can basically build anything any size. You dont have to worry about using the proper port(s) to tune it to a frequency- that is only dictated by the size of the enclosure.

Anyway, hope this helps!

IMO homemade =

the T/S paramaters pretty much dictate which box that speaker was designed for. id base my choice on that.

Yea I'll probably just stick 2 ported.Thanks everyone.
