I would far rather see a company put the money into top notch drivers and a well designed crossover than put it into bass extension. We have subwoofers for that job. Now if we were talking about 10,000-15,000 speakers it would make sense.
While I agree with you fully, you still have understand that as long as this remains a male E-penis hobby, rational concepts like subwoofers wont apply. Subwoofers aren't seen, they're just heard (felt). And they work, kicking *** over even the hugest phallic tower. But still, towers with subterrarian W.A.F are mainstays at any Electronics Convention, as if to say, "This Tower is the apex of all things manly, you must have this or you have NOTHING!" So it stands to reason we aren't buying towers for their performance, we're buying them for our status.
I personally am not a fan of many speakers with more than 3 drivers, and have found bookshelves as accurate as any, and passing of an old time convention of wisdom in audio (the more drivers, the more problems). If a bookshelf can get down to 90 hz, I'm in good shape as my dual 10's in each corner make everything else lovely.
That said, I, too, would expect 30 hz performance in such a tower as these.
