Onhwy's system with Harbeth Monitor 40 will go pretty deep, enough to satisfy almost anyone, and with an inexpensive but powerful amplifer, will play louder than anyone can stand. Add a good subwoofer for not a lot of money anyway, and you get you 20-25 hz bass. Really no reason to spend more money, (or nearly as much on cables). The reason people spend more for speakers is they prefer a different flavor to their sound. Some pretty knowledgeable people consider the Harbeth M40 to be sota, yet it doesn't please everyone. It does go extremely loud, however.
I have no idea why anyone would spend a fortune on amps, etc., but if that's their idea of fun, who cares.
