1. A loudspeaker cabinet, comprising:
a front panel;
a back panel;
a first panel physically coupled with the front panel and the back panel;
a second panel physically coupled with the front panel and the back panel;
wherein the front panel, back panel, first panel, and second panel jointly enclose a cabinet cavity, the cabinet cavity having a first opening substantially at a first end and a second opening substantially at a second end;
two or more speaker drivers mounted in the front panel, wherein centers of the speaker drivers are mounted within a critical distance range from each other;

the fill density is within a fill density range from 2.1 to 5% of the material density;
wherein:
a ratio of a first perimeter of the cabinet cavity at the first end divided by a second perimeter of the cabinet cavity at the second end is less than eight tenths (0.8);
a ratio of a length of the cabinet cavity divided by the second perimeter is at least two (2);
at least two of the two or more speaker drivers are configured to cover substantially equal frequency ranges; and
an inside of the front panel and an inside of the back panel are tilted towards each other, and/or an inside of the first panel and an inside of the second panel are tilted toward each other.
