Crossover-less Speakers

I was very pleased with my old Sonus Electa Amators and Minima Amators of past. They used a very minimalist crossover, which yeilded very good damping of the drivers, and thus a very dynamic pressentation!
Only problem was that these speakers were finicky to the power being pressented to them. Rather, the voltage out of the wall!
When the voltage was high, say 124 or above, (at night), the sound was dark and rather bland. During lower voltage, the sound was simply SUPERB!!!
Bobby Palkovic from Merlin mentioned something about this in conversation. I wonder is this is common to many simple or crossoverless designs?

I own Bastanis prometheus speakers. It does have one cap and two resistors yet the manufacturer still calls it crossoverless. To me crossoverless means zero caps and resistors. Having said that the speakers are the only component I have no plans on replacing right now. They are the most live like speakers I have heard.

Zu has all this figured out. Contact them and find your answer. I owned Goldmund, Avalon, NHT, Magnepan, DIY, Vandersteen, Aerial, Spendor, Sound Labs, QUAD, JBL, and many others over the years. Zu has it all figured out.

I'm with Macrojack on this one. I couldn't start to list all the speakers I've been through over the past 30 years, but Zu's are something special; especially with tubes.

Supravox's 8" field-coil driver in the factory-recommended enclosure is probably the best-sounding high efficiency crossoverless speaker I've heard (I've never owned a pair). Incredible imaging (I'm not normally an imaging freak, but these really do it well). Very close overall (and in some ways better than the Supravox) is the PHY 12" fullrange with a piezo tweeter-on-a-stalk, which I did own and enjoyed very much. Either of these can stand on its own without help from other drivers, provided you don't expect room-shaking bass power. They are finesse speakers. Now when I've used other, less expensive and less capable fullrange drivers, I've often augmented 'em with a powered woofer section and sometimes with a supertweet as well.

Macrojack, maybe this is none of my beeswax but...

You aren't by any chance a Zu dealer, are you? It sure looks like you're claiming to be one over on audiocircle.com. Tagline under your avatar: "I am a dealer for Grado and Zu."

If so, how long have you been one?

Is the correct term "Zu Listening Post"? Who else here is a "Zu Listening Post?"

Anybody else think us industry affiliated folk ought to disclose our affiliation when plugging a product that we sell, especially when we also put down ten competing products by name in the same post?

For the record, I'm not presently a dealer for any crossoverless fullrange loudspeakers.

Thanks.
