I suppose you're talking "flat" down to 30hz. rolling off is another story... top string on the bass goes to 41hz. It would seem 30hz sufficient... save the rest of the show. the dealer said the JR's do 36Hz. it's a mighty impressive 36, if you ask me... and with six inch drivers no less.
I'm doubting many units under 4K that are fine above 50 or so, aren't going to produce the lower registers as too much of the music resides up there.
Maybe a sine wave generator can shove a signal into a speaker but who wants to hear that? the point made about the amp is IMO important too. I've long since lost my fascination with specs... and the ears have it as much as is possible. What happens in a 'chamber' during imperical measuring and 'real world' listening are just a bit different, I believe.... but I suppose one needs a spot to start. 30Hz ain't a bad place neither given real world costs and pricing. that's one reason why I've been such a proponent of adding a sub to about whatever speaker.
Great thread... I am anxious to see how it turns out, or who wins.
