This pair of white Nenuphar now live in my music room. I'm running them on 3.5 watts of 2A3 to which they respond beautifully. I could not be happier. Thank you Peter for posting this video. It's a very cool thing to be able to share this with my friends. Thank you also Jon.

I like these speakers, but.... WHY in heavens name, do we always have to hear this semi intellectual half acostic boring music, through all these widely expensive systems..???

Too glassy in the treble -- like frequencies bouncing off of panes of glass. These may be full range, but there is too much of treble and the rest of the frequencies seem to be somewhat diminished.

The piano sounds great but the "S"s are terrible. Like you can hear a really bad resonance at about 7 khz (on the "S"s).

I wonder if this youtube demo actually captures any of what this system can do? It has to sound much better than this.

Its undoubtedly First Watt sound

My description: The loudspeakers bring the sound so uncoloured in an openness where you don't miss anything in terms of sound. These Full range speakers - which do not use crossovers - no longer sound like "loudspeakers", as has always been the case. They sound neutral without adding or removing anything. I describe them with the following words: These music radiators have a: "white sound", that is: All frequency ranges come into their own, with an impulse fidelity that is seldom found in loudspeakers. - What the amplifier delivers, they deliver in a ratio of 1 to 1. The unrestrained speed of the membranes and the 82 strong neodymium magnets bring this ounce of naturalness. Meine Beschreibung: Die Lautsprecher bringen den Klang so unverfärbt in eine Offenheit, in der man klanglich an nichts vermisst. Diese Breitbandlautsprecher - die keine Frequenzweichen verwenden - klingen nicht mehr wie "Lautsprecher", wie es immer der Fall war. Sie klingen neutral, ohne etwas hinzuzufügen oder zu entfernen. Ich beschreibe sie mit folgenden Worten: Diese Musikstrahler haben einen: „weißen Klang“, das heißt: Alle Frequenzbereiche kommen voll zur Geltung, mit einer bei Lautsprechern selten anzutreffenden Impulstreue. - Was der Verstärker leistet, liefern sie im Verhältnis 1 zu 1. Die ungebremste Geschwindigkeit der Membranen und die 82 starken Neodym-Magnete bringen dieses Quäntchen Natürlichkeit.

Finally...

VTA is definitely high.

Did he say the speaker are ported at the bottom a transmission line? How does that sound with that pass Labs amplifier is it just solid state or both, How much do they sell for? If the MOSFETS are not available why can't another company manufacturer them under licence? And could it not be made out of discrete circuitry instead of MOSFET might sound even better. I'm assuming a speaker like that needs a good amplifier because it's very revealing of the electronics of the amplifiers flaws, I remember when they first bought them out there used Italian valve amplifiers to compliment them, have you tried these valve amplifiers out there supposed to be quite reasonably priced I think! valve better than solid state or both. And another thing I don't see anybody else reviewing cube audio speakers just you why is this there's been a lot of shows on the internet nobody else has reviewed them far as I know.

Those are like the Zu Essence on meth. Like it doesn't even sound like the same song when you listen to the source material.

I hope they don’t get insane $

Yet another KZfaq "listing test"...
