xx1 Posted June 5, 2012 Report Share Posted June 5, 2012 is it harder to get loud in a larger vehicle??? (without removing any seats) for example. a chevy suburban leaving the 3 rows, using only the trunk for subs. will be harder to get loud than a volkswagen golf?. which trunk is so close to the front.

Nikitaaa Posted June 5, 2012 Report Share Posted June 5, 2012 (edited) put simply, yes I've actually been quite confused about this as well. My wagon is pretty long and narrow. I've been told that the distance between the dash and port needs to be as short as possible but I've also heard that low frequencies need distance to build up making my wagon a prime vehicle. Can someone shine some light on this for me?

Guest Posted June 5, 2012 Report Share Posted June 5, 2012 the less amount of space (air) the subs have to move, the louder it will be. thats why walls are so loud Quote Link to comment Share on other sites More sharing options...

HHR Ed Posted June 5, 2012 Report Share Posted June 5, 2012 Sound waves have a length to them. There is a certain distance between the peaks of the wave, or the compression nodes if you prefer. This length can be found by dividing the speed of sound by the frequency. For example The speed of sound through air at sea level is approx. 1130 feet per second. Divided by 20hz equals 56ft for the length of a 20hz wave. Most cars bass is between 30hz and 60hz. So this means waves between 37ft and 18ft. All of which are too long to entirely fit inside a standard passenger car. So we use the half and quarter wave method. If your interior is between 9 and 4.5 feet long, then you have the potential to play these frequencies very effectively. Now, in fluid dynamics and the physics of air pressure, we know that it is much easier to compress and vacuum smaller amounts of air as compared to larger amounts of air. Therefore, it will be easier to create high SPL with smaller amounts of air mass. So smaller cars have the greater POTENTIAL to get louder, as long as you know how to build for it. And we run into the frequency conundrum, so if you want a small car to still play low frequencies effectively, there is a limit as to how small you should go.

It can and does to an extent. That has long be an issue with SPL competition, but the new TL is not effected by elevation, just your system.
