so they respond well to constructive criticism and you criticize their capability? The old bravus was a high output and punchy sub. For a lot of music that is something many people really like.
they went with passive radiators instead of two active drivers, whoch gives it more low end as Gene pointed out is more desired, at least for home theater. it likely reduces the midbass output capability by a solid 4-6 db on the other hand. it might measure better and technically sound better but who knows if it appeals to the masses better?
both are valid design choices when the desired end result is more than just making the best no compromise sub. there is more to it than just knowing what works. it is about actually selling the product, and aperion is obviously trying to differentiate their sub so that it isnt just the same driver/port box as everyone else.
