Which way to face subwoofer?

Hey, i've been wondering this, if you have a subwoofer in the trunk which would be the best way to face it based on bass/sound quality.... Towards the trunk, towards the front, etc etc... I think ive heard some talk of it..

sedan = towards the rear.
Liftback = rear or straight up

you always want to load the bass wave off a surface before it gets to your ears... it helps focus the wave .... think about it as condensing, or concentrating it like what a funnel does with water.... thats what you do when you bounce the wave off a surface first.

sedan always face rear with a sealed box
hatch backs toword the rear with a ported box

sedan with ported no such a good idea
hatch with ported alot more bass due to the fact you can use the air space in the car since your trunk is also connected to the interior without any blocking this is why majority of the suvs and trucks run ported

people run ported cause they care more about absolute volume (as in sound) than cargo area.

not really true some subs out there require it to be in a ported box and not a sealed one

require is a very strong term.... I've yet to see a driver that sounds like absolute poo unless in a ported box.

Yes, the QTC, Vas, and Fs do have a great effect on if the sub is best suited for ported or sealed, but with virtually any sub on the car audio market you can get decent results with either.

a QTC of .4 or lower means ported would be great
A QTC of .4-.6 means Sealed would be best
and anything above .6 means IB would be best... but IB really is the same as a giant sealed box.

most car audio subs have QTC's in the range of .4-.55 as the best way for stereo companies to make money is to make it work in BOTH types of boxes and have a broader market sector.

ported will generally gain you 3dB, and have a similar (slightly better response)... if you build the box right.

sound dampaning is for the rattles you have in cars... expensive.. but helps alot

well heres proof do your homework before you come back with what you have to say http://www.ddaudio.com/dd/caraudio/e...Size_hiEff.asp
try putting this in a sealed box and tell me it doesnt sound like poo when in a sealed box i install these everyday and we build the boxes and all of them a required to be ported higher watt subs sound better in ported and sound like poo in sealed. lower watt subs sound better in sealed boxes. the whole theory of a port is to tune the sub to a certain hz and provide more air space to give a deeper bass tone a low hz depending on the port length and wood density and air space every sub out there has a different air space requirement and not all boxes that are universal actually within a spec of what the sub needs there for the only way to get the correct air space is to build a box with the specs they recommend

I think you'd have an easier time arguing that a sub can be sealed, but not ported... as some lightweight cones & suspensions can be way to easily overwhelmed by the pressures found in ported & bandpass enclosures.

I almost ran a DD sub about 5 years ago... yeah... they get loud. they are beastly subs meant to get loud and ARE NOT known for having any sound quality characteristics....(read: they sound like poo regardless). They'll survive anything short of a nuclear blast. They also have a bad rap of having published T/S specs as much as 50% off from reality.

I am the first person to argue that each sub plays optimally in a specifically designed box. I don't think the point of a ported box has anything to do with giving the sub more air space... that's not the point, thats just often a requirement.


Like I said before... the overwhelming majority of car audio subs can play in both.... DD makes up an extremely small percent of the audio market. They are a brand for enthusiasts who are into getting very loud.

I'm perfectly happy to talk speakers with you over pm, or even AIM or e-mail.... I don't really want to hijack this thread tho.
