I'll even let you use Crutchfield, but no IDs...
This is a survey. Not to be taken as the OP looking for advice.

JL Audio is like the Tesla Automobiles of home subs. So, it's like asking why Tesla doesn't make a gasoline powered vehicle. It's not their thing. This concept clearly doesn't work for everyone. If you ask a friendly local dealer about JL Audion subs they will tell you that they hung the moon and stars. If you ask folks here on AVS, you get mostly head scratching. I think JL likes it that way honestly.
Also, due to the technology that goes into JL Audio (home) subs, simply calling them sealed, and leaving it at that, is somewhat of an under characterization.
