I disagree. The type of speakers mentioned are exactly the same as could be bought in stores for the last 30+ yrs. A tweeter over woofer(s) on the face of a (most likely) ported box. There is and has been a mind numbing number of those in the marketplace. With minor variations (like "ribbon tweeter" or "cone material XYZ", etc, touted as radically different in sound), there is a generic sameness to the sound, instantaneously identifiable as "loudspeakers in living room" despite glowing descriptions as to otherwise. The main difference seems to be cosmetics, something like the Salk having a superb, beautiful finish. The things that really make a difference, like uniformity of polar response and its effect on the reverberant field, dynamic compression, smoothness in room LF response, etc....not so much. The performance parameters...and limitations...of the near infinite number of dome/ribbon-over-cone-in-box, is well established.
What I would suggest you do is listen for yourself, to the actual loudspeakers and decide, rather than rely on the advice of others (including me) as to specifically what to buy. Even though this might prove difficult or impossible for some models, it's your money. Spend it wisely. Audition what you can locally, or make sure the non locals have a return policy.
A speaker either meets your "sounds good" criteria or not, there is no "useless for low volume" or need for a "more expensive" receiver, unless the one you have lacks the required features (for surround format, digital thru-put, etc.).
