Peter, you are WAY too conservative in stating your Marketing Hertz. In my world of electronic projectors, there's Marketing lumens and there's actual ANSI lumens. 10% to 40% variance. Go for it, and claim 40 Hertz
On a serious note, members: I listened to Peter's H-pas demo in Vegas, and like the other attendees, was amazed at how those small drivers loaded the demo room with serious bass!
