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

Speaking of Tektron tube amps, they are the 2a3 amps used by Cube Audio at shows. Robyatt Audio carries four of their smaller amps/preamps.

Looks like the amps with 2a3 tubes are 2.5 watts/channel. Is that enough to hear at sane listening level, assuming you sit 8-9ft from the speaker ? What about 300B tubes ? has anybody been able to listen to a 300B amp with the Nenuphars ?

@rwpollock Wow, had seen the name in print, but didn't known anything about those amps. They look like a ton of fun.

For my "sane" levels it would be, but it also depends upon the size of your room. 20-40 sq meters is 215 to 430 square feet (20' x 20').

From the Cube Audio website:
"The Nenuphars are dedicated for rooms of 20 - 40 square meters. They are a perfect match for a tube amp with at least 3 Watts per channel. Our personal preference is somewhere around 2A3, Px4, 45 tube-based amps. Nonetheless, most solid-state amps (especially those working in A-class) are also an amazing match for the Nenuphars."

"I bought my SIT-1 Mono's (Demo's) for about $500 more than what the SIT-3 goes for new."

That sounds like a great deal. Didn't they sell for $11K when new?
