I have a 12" Pioneer running on a Pioneer amp. The sub is in a sealed box and sounds pretty good. Is there much of a difference in sound from a ported box to a sealed box? Most home audio systems have ported speakers and seem pretty smooth with bass. Does it make much of a difference in car audio?

Sealed Enclosures

Straightforward in design, the sealed box is nothing more than an airtight enclosure whose purpose is to enhance speaker performance. When a woofer is installed in one, the sound waves that emanate from the front of the speaker cone are separated from the rear-firing waves. This improves bass response, since opposing waves can cancel each other out when they aren't isolated. Superb damping, good power-handling capability, and simplicity of construction make the sealed-box enclosure an ideal candidate for a variety of installations. A sealed enclosure will be the smallest (for a given response shape) and will have good low frequency extension but may not have the best low frequency extension. If space is limited, this may be your best choice.

Vented Enclosures

Vented enclosures – also known as ported or bass-reflex systems – are more complex than sealed boxes, but the extra construction work required to install a vent has its rewards. Vented boxes are more efficient than their sealed counterparts, since they channel sound waves from the front and rear of the cone into the listening environment. Other virtues of the vented design include better reproduction of low bass, a reasonably flat response curve, and low distortion – provided the box is properly constructed. A vented enclosure will generally have a better low frequency extension for a given response shape (alignment) but would require a larger enclosure. If you made the enclosure as small as the sealed enclosure but ported it to gain the low frequency response, the output would deviate from the desired flat response.

so in short...

sealed box = simpler to make, good space saver

ported box = harder to construct, might sound better, but requires larger space to get the sound you want.

could swore i saw what i thought i saw last night.... sometime after 7-7.30pm

Question What is the difference between a valet key and master key?

Best Answer - Chosen by Asker

Master key can open doors, trunk (inside or outside of car) start your car open the glove compartment etc! The valet key is mainly used for Valet to park your car, it can start your car up & lock it thats it! It cannot open glove compartments maynot open the trunk. Never give your master key even to the mechanics.

go on and try out the machine that the germans used to send out secret messages

saw a 03 (i think) corolla with trd/toms badging (cant remember which) there at plumpton one time... i left a home made card promoting TOCAU on the windshield.. turned out it was some old middle aged lady driving it? wierd

out of curiosity, how often would you change the fuel filter?

there are a few mystery corollas lurking round plumpton shops...

hate going there now witht he construction.. when i try 2 get onto hyatts road when leaving i 4get that the plastic barriers are blocking the way so i gotta turn round to the mcdonalds side and go home that way..

personally id leave it out.. give the police another excuse to bust you for something... "you could be using it for something else". out of the car i mean.. not your sig :P hell do whatever you want with your sig! hehe

sensitive to wood?

your av is the reason i didnt squash my corolla.

besides your rims, mine would look exactly the same :P

mabuhay :P

sorry man thats all the tagalog i can speak! (im in sydney, but my family is from visayas area) welcome to TOCAU!

are you asking us to find the parts here in australia?

Ill keep a look out, but my guess is that you can find the switches you are looking for in ebay.

another place is http://www.ozeparts.com.au/ - youll probebly find the parts you are looking for under 1998-1998 AE112, since im not 100% sure if we have AE111? it looks the same front as your car.

im guessing its a sedan right? we have both sedan and hatch here, but i think the ozeparts website only lists the hatch.

Ive found the parts in philippines are a lot cheaper when you convert it to pesos. Unless you have a good job and a credit card i wouldnt bother ordering parts from overseas if i was living in phils.

good luck man.
