Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

David, very nice review in Stereo Times. Are you the 'Davis' mentioned in the article?

Yes. Davis Ten. Clement needs to up his editing game. : )

hard to say without trying and comparing with a known reference that works with the Cubes.

@coot  I believe the damping factor is 200. I could not find anything in a quick search regarding negative feedback. Even though the No. 8 has 18 watts of Class A before going A/B, it's 200+ watts into 6 Ohms far exceeds Cube's recommended max of 40 watts.

Will it work, YES. Is it the best match/pairing???

Thanks guys. I guess my real question is, Why the max of 40? Does too much power damage the speakers? Tektons are quite sensitive as well, but I know people who are using high-power ss on them without damage. Anyway, thanks.

Agree with David. It will definitely "work" with the Nenuphar. There’s certainly the possibility that it may do more than merely work and sound good as a pairing. The point is the Coda Technologies # 8 is designed as a high current capable amplifier that doubles its wattage when speaker impedance in halved from  8 to 4 ohms. These kinds of amplifiers usually are low output impedance designs with generous levels of NFB.

It uses 20 transistors per channel to accomplish this. The Nenuphar was designed for a very different type of amplifier topology and circuits. You just never know how these pairings may actually sound. So the obvious key is listening to this match and make a determination.
Best of luck coot,
Charles
