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

This is a nice thread. A couple of thoughts based on system building...

Regarding whizzer cones, having used concentric, dynamic, hybrid dynamic, and full range hybrid speakers, I find whizzer cones to be no impediment to consideration of a speaker's sound as exquisite. I am currently using various speakers with whizzer cones and find they are as capable as any of achieving resolution on a par with very different drivers including ceramic, metal, etc. 

Regarding damping factor, I had an interesting review of the Gold Note PA-1175 MkII for Dagogo.com, which offers an on the fly Damping Factor switch. This is one of the most curious and beneficial amp functions I have found in a SS amp. at DF of 25 the amp sounds quite like a SET (only with more power) and at DF of 250 it acquires the characteristics expected more of SS. It reveals how much DF does influence the speaker's performance. My experience was that lower DF will cause a plumping and slight rounding of the bass with less absolute cleanness on edges of notes, while higher DF does the opposite. 

Great posts all! Thanks all! 

@khragon   Congratulations on your excellent results with your First Watt SIT-2

Thanks also for sharing the photo. Very nice.

Question: based on the photo it 'appears' your seating position is farther back...how far? And do your speakers cross-over behind you (they look to be set up with minimal toe-in)? Thanks.

@toetapaudio  Are you referring to isolation in general or specific to the Cube Audio speakers? If specific to the speakers, can you share more? Thanks. 

Imo spikes are not beneficial,

@douglas_schroeder   Your post was educational and helpful to me. Thanks! I'll read that review.
