It depends on how you have designed your car system. You can't hit something if you haven't targeted it. But the car has great potential, if you explore it, to play 20 Hz or even 15 Hz much louder than headphones. Headphones that target the low end can usually beat subwoofers when there is no...

You should research before reacting this way. There is a scientific publication about this: Olson, Harry F. (1967). Music, Physics and Engineering. Dover Publications. p. 249. ISBN 0-486-21769-8. Under very favorable conditions most individuals can obtain tonal characteristics as low as 12...

@shredder1 , I won't quote your last post because I find it to be inappropriate and lacking in any sort of constructiveness. PS: If you ever do a hearing test, you'll notice they always use headphones.

The measured car SPL reveals that there is a lot more going on in addition to the window port effect that I described. In regards to the cancellation effect, can be observed in the mid-bass. I believe that if the sub is placed at the center of the car (over the back seats) and the car is...

Oh, so you were still talking about IB. Sorry for my misunderstanding. A raised floor takes too much space from the trunk, partially defeating the purpose of an IB. But a thin mesh seems enough. Like this "Galvanized Steel Mosquito Screen":

Many years ago, while driving my car, I had the most incredible bass experience among all of my experiments. Surprisingly, I was using just two 10-inch speakers. One was in a BP6 box placed at the...

Hmm. That's a car with a much smaller cabin with 1500 liters since it does not have the back seats, and it probably has a slightly bigger window (maybe 45x45). Throwing in those numbers tells me that your windows were being tuned to 37 Hz. That matches with the tuning of most sealed car boxes...
