Coman61, I have quite a bit of experience with various planar speakers and unfortunately I don't think that's the answer for you.
I think your requirements might be best served by loudspeakers that use high quality prosound drivers.
One of the challenges that can arise with conventional speakers is differing power compression characteristics among the drivers. Briefly, different drivers don't all get louder at the same rate as the input power is increased (theoretically it's 3 dB for each doubling of input power, but in practice this is rare outside of prosound drivers). This phenomenon is called "power compression", or sometimes "thermal compression", and there's a correlation between low power compression and high efficiency. Usually tweeters are padded down to match woofers, and usually tweeters have less power compression than woofers. So what happens is the designer picks a loudness range in which the speaker will sound balanced. At much lower volume levels, the woofer is louder than the tweeter so the speaker sounds dull. And then at very high volume levels, the tweeter is louder than the woofer so the speaker sounds bright. You may have noticed this with some speakers.
One of the advantages of single-driver speakers is that the tonal balance doesn't change with loudness level. But single-driver speakers lose articulation at high volume levels because the voice coil travels beyond its linear limits on loud bass passages.
Prosound drivers are not immune - they do suffer from power compression at high power levels, but typically we're talking about levels that would produce in excess of 115 dB. So it's essentially a non-issue at SPL's likely in a home environment. If you want a speaker that really holds it together at very low to very high volume levels, high quality prosound drivers make a lot of sense.
I've e-mailed you about a speaker I sell that uses high quality prosound drivers. Other contenders would be Klipsch Heritage series and Pi Speakers. Going well north of your price range, Classic Audio Reproductions, eXemplar, Avantgarde, and Edgarhorn come to mind.
Best of luck in your quest!
