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

The Raido/Børresen in shows always have a wider placement configuration very close to the side wall with aggressive toe-in towards the listening position. Maybe they don't care for the sidewall reflection based on how the speaker is designed. I am still playing to the positioning with the Nenuphars and experimented a  little with the toe-in and I find aggressive toe-in make the sound too bright and sharp for my taste. Currently they are toed in about 5-10degree. How much toe-in do you guys have ? Between, anyone using a pair of subs with the Cube ? 

Initially I had my Cubes pointed straight ahead but have found they do sound better with a slight toe-in. Haven't tried corner placement because of furniture constraints.

Boenickes and Cubes are quite different animals but share something that I find attractive. It might be called flow or a more natural sound. I don't care for speakers that "push" music at me.

Btw, I just wanted to say how exemplary this thread is. Just pure, helpful, experience sharing and education. It's really a pleasure, thanks.

@stephendunn  Congratulations on your success with the Vinnie Rossi integrated and resistor solution.

@debjit_g If you are still looking at amps, and a 2A3 is still an option...

My Found-Music 2A3 drives the Nenuphars with ease. I top out at 90dB averages when I choose to crank the music. We have had it up over 100dB averages for a couple of audio buddies who prefer their music really loud. Above 90dB levels, my untreated room asserts itself as an unwelcome actor.

[Note: by average, I mean the average over the recording (including peaks)]

My usual (and normal) listening levels are in the low 70dB range with averaged peaks in mid to high 80 (spikes into the 90s); recording dependant, of course.

Room is 19 ft by 26 ft.

I am hoping that the 2A3 can power the Cube’s to a comfortable listening level when the listening position is 8-9ft from the speaker.

Not all 2A3s are created equal. I encourage you to reach out to @charles1dad and others qualified to address build quality.
