Windows down = less bass?


Recommended Posts

whats your car peak at?

uhh, the hell are you talking about

acoustics are a bitch.

/thread

did u test it on a meter?

again, the hell are you talking about

as stated, every car is diffrent, mines louder with the windows down, or the drivers door open and all windows closed, but kranny pretty much put it perfectly

acoustics are a BITCH

Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k!

Why would you EVER WANT flex?
huh?...flex is what can make the lows lower and more air being pushed correct?

Every car is different. My Ram is louder with the windows down but I swear my friends Jetta is louder with them up.

i have a envoy which is damn near the same as your car. The bravada/envoy/trailblazer/volvo line is pretty much the same stuff just a different body style and features that come standard. My envoy peaks at 49Hz and mine is louder inside with my two front windows down for hitting the super low notes but for higher notes it is loudest all sealed up.

i just dont get why you guys are talking about peak this, peak that, talking about peak right now is like trying to talk to druggie about goats

its pointless

what hes trying to figure out is why he looses so much sound with the windows being down

heres an example OP, in my PT, if i put my back windows down even a little bit, and my front windows down completly, ill loose about 1/2 output (to my ears) as soon as there fully closed im back at 100%, when i close my windows its not as loud to my ear because the soundwaves are "trapped" in the car, this is the case in roughly 70% of cars depending on the set up(i may not be 100% correct on my definiton here)

soution for you, try a diffrent box, move the box a bit, try diffrent combonations of windows

could it be where the port is tuned so low, and the windows going down are lowering it even more?
