Alright.. I have head this countless times "Install is 90% equipment is 10%, a simple slot port box isn't going to make your system amazing (or something along those lines)"


WELL, I want to know What other choice I have for boxes... I have heard of "T-Lines", Sealed boxes, "Aero ports", and thats about it, well, the slot port of course.

So what do you do to make a box that will achieve maximum sound? I know subs, and vehicle have a lot to do with it... But Since I'm not making a box right now, and want more of a general knowledge, I don't really want to include those factors..


Thanks,

Mike

1,500+ posts but you don't know how to design a worth while box?

not surprising.

Why don't you Google "DIY subwoofer" and read every link that shows up?

Each box is going to act diffrently in diffrent cars. Go to TTB (teamtoxicbass.com) and look around there site. That might help.

4th and 6th order bandpass:) Don't ask me about them, my knowledge is pretty limited because I've yet to try them out:laugh:

aren't these designed for peaky output? like a small range of frequencies, but loud?

15-100hz is a pretty small bandwidth of frequencies.... But, if you increase bandwidth, you decrease efficiency and if you increase efficiency, you have to decrease bandwidth.

Subwoofers in general have a small range of frequencies.

Most ported subs in cars have peaky outputs.

A properly designed bandpass box can peak loudly or cover many octaves. Depends on the design.

The search button is your best friend. It has been my best friend, and still is.

Have to search for answers because now days the forum is full of members just adding smart azz coments. Search and look at post back around 2003-04 where members where helpful.

A good alignment mostly depends on the vehicle and how well the enclosure is implemented with the vehicle's interior. You might have an enclosure that pegs the meter with car "A" but does very little in car "B" with the same power.

I have some question with some things that came up.

Like what are they, and how do I find them.


Xmax = maximum linear displacement (mm)
Dia = Effective diameter of driver (cm)
Qts = driver Q at system resonance
Ql = box losses (Ql=infinite (10000) can
be assumed for most cases)
Vas = equivalent air compliance (litres)
