Before my time with Arendal, I used to sell the B&W subwoofers, so I do have a lot of experience with them.
As I said before the 1723 Subwoofer 2S will outperform the B&W in terms of dynamics, impulse response, and musicality.
It will play down lower with more control.
We also have a very refined amplifier with class-leading protection circuits, that are basically inaudible.
I can tell you that I have run into crazy and nasty sounding distortions and plain overdriven bass drivers with the B&W DB subwoofers with movies like Blade Runner 2049.
Neil pointed out correctly that with such small enclosures and the performance you get, a powerful amp is far from overkill, it is needed to work.
