Fast Bass

[[]0[][]v[][]0]

I've noticed a phenomenom, or maybe I'm just stupid. It seemed that at stand-still, or low speeds, that there seemed to be more bass than when traveling at highway speeds.

Now mind you, this is in a 2000 Mustang with a 15" Titanic with more than 500 watts going to it.

Is this with the windows down or up? The bass response can be quite different (typically louder) with the windows down (car turns into a big bandpass box with the window opening as a port)

I could imagine that at speed the air rushing past/into the car could disturb the front chamber resonance (cabin space) enough to reduce bass output.

I made sure to test this phenomenom with the windows up for both situations. It may be the case that I was expecting something, after I thought I noticed a difference.

You'd be surprised at how much low frequency energy increases with speed in a car, especially if you have the performance package. That could have the effect of masking woofer output if you listen at any volume below insane.

I'm almost positive this has to do with road noise. My car stereo sounds best, and fullest, with the windows up and the car not running. At speed I too have noticed I need a little more bass.

Guy,

I believe you're correct and to be honest, I had taken it as a given.

Yeah, I agree. It's road noise.

I have a pretty solid and well built car, it's not noisy compared to many but I have to turn the volume right up to overcome road noise on the motorway. As a driver, I'm not really consciously aware of road noise when the stereo is off, I guess I just tune it out.

According to wikipedia (http://en.wikipedia.org/wiki/Horsepower) 1W = 1/ 735.49875 HP.

So you got a 0.68 HP Mustang - no wonder speed is a concern.

12” on a Mustang…………………. Not exactly low profile.

Sorry … thought this was DIYauto.

anyway

that is because of the harmonics coming from the car,the different vibrations absorbes the bass or gives more depending on frequencies

Fast bass are the ones that bite your hook quickly and do not let go... then you eat them...
