The last month during the Munich show some folks from Ascendo Audio 50" showed a new 50” subwoofer.     https://www.youtube.com/watch?v=jIyUmpz9dII   I am not wild about what I saw, it was WAY undersized enclosure for the displaced volume and this should sound horribly controlled, compressed and homogenized.  Most likely the will put in there some kind of active feedback with pumping in a huge amount of power, the solution that has zillion own problems. I was told about 78” subwoofer made and I am sure it is not the last size out there.     I did not hear the subwoofers above, not that I have interest. As I have a very low expectations. The biggest woofers I head was right here a Boston the fellow I know has a pair of EV 30” subwoofers working together. The sound he has in bass is horrible. I do not blain in his bad bass the EV woofers. The quality of bass is contingent upon so many reason and it would not be smart to blain just the drivers. Still, the preoccupation with the larger driver size makes me a bit puzzle.     So, if we have a huge woofer vs an equivalent of the same surface of the small woofers then what solution would be preferable? I naturally a bit afraid of the very large woofer. The biggest I had was a pair of 24” Fane, which was not good and here is my experience with large drivers is over. I personally did not see any more of less expensive or good motors made for more than 18” drivers. Still, if would be VERY interesting if somebody make the identical motors for let say 24” driver and the equivalent let say 10” drivers and to compare the result.
