Hi Tom !
thanks a lot for the very helpful advice
Physics are not my strongest point ... but i think i have understood that is a tricky issue. With many variables.
Very interesting the concept of "room corner". I did not know this.
So the room size fixes the lowest bass that can be reproduced in the room. Good.
As i usually listen in small rooms i think i will have to do without the lowest bass for sure.
Thanks a lot again.
Kind regards,

Hi
Well i am afraid i have been a bit confusing.
The idea that low bass is limited by the room size is audio folklore.
The reality is that low bass IS EASIER the smaller the room is because of the "room gain" slope. That is how one can get 15Hz bass in a car with a sealed woofer that rolls off at 50Hz sitting outside of the car.
Hope that helps
Tom
HI and thanks again indeed and this is very exciting
Yes i have misunderstood but it is important to me to know that very good and low bass can be obtained in a small room.
Just another point and sorry if i make very basic questions.
I read that in order to get the same SPL at the same Hz in the bass a smaller woofer must have a bigger excursion than a bigger one.
Then i have also read that a big excursion of the woofer can lead to distortion and the best woofers are those where the cone excursion is minimal. So for low bass a big woofer is much better than a long travel smaller one.
I am not sure of this because i see many subwoofer where the cone had big excusrions indeed. They are not very big in diameter also.
Thanks a lot again.
Kind regards,
