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

Hi Cal,
This respectful and helpful type of decorum and behavior was pretty much the norm in an earlier era on Audiogon.  There have always been differences of viewpoint amongst posters on this forum. However the way in which they were managed was  more mature and reasonable. 

I really began  to notice a change in interactions and increased trolling about 5 or 6 years ago. Not sure what's responsible for the evolution of this behavior but I'm glad it hasn't infiltrated this enjoyable and informative thread.

Now this will blow your minds! The speakers have binding posts. These WBT posts are very good but not as good as hardwiring. But what is really not good is the input tip jack on the speaker driver.....looks like it only takes a banana plug. If you really want to hear the speaker....then this is what you will do:

Remove the driver from the box and hardwire/solder the best wire you can source directly to the voice coil wire.....right at the point where it is soldered to the tip jack.......then remove the binding posts in the rear of the speaker and run this wire directly out and clamp or solder it to your speaker wires. Seal up the hole around the wire coming out.....OMG.....

With two sets of connectors gone and better wire.....you will hear things you never thought this speaker could do. This is not subtle. Even better would be to add a set of Ground Enhancers right on the driver negative post.

When you go to sell your speakers (what, someone will sell their speakers?!?) you can put it all back to stock and no one will ever know you modded it.

Ground Enhancers are loops of litz wire that you put on the negative terminal of a speaker....(or directly on the speaker driver). These loops of wire act as a better ground and enhance detail.....very cheap....$30 the pair. Yes, I sell them.....I will become a millionaire if you buy a pair.

I understand that only about 1% of audiophiles are adventurous and feel comfortable soldering and modding expensive gear.........but if you are that one person, then you will rewarded with much better sound......and all for very cheap.

Cal, agree. 

Ricevs, yes I concur, I first tried this 30 years ago with good results.

I've thought about this, but removing the drivers, let alone soldering, was too intimidating for me--like you say.
Obvious questions are:  
1.  what kind of wire? silver? copper? both?
2.  and once you have the right wire why not run it directly to amp, skipping speaker cables altogether?

More on Vinnie Rossi L2i.  I'll just come out and come clean on this: I am enthralled by the way this integrated amp sounds with the Nenuphars.  It is a no joke, jaw dropping experience, blowing out the side walls and back wall and probably ceiling if mine weren't 18' high. And it's so tonally real and present and alive that I just can't find a nat to pick. Except that problem I just posted about it not delivering the big bass.  Well, I discovered a way to fix it...now wait for it...TURN UP THE VOLUME.  I know, I'm an idiot, but a conscientious one, trying to keep volume levels equal when I go from one amp (the SIT-1) to the other, the L2i.  I normally listen in the low/mid 80's db perfect for my size room for jazz and chamber music (which is maybe 72% of my musical diet).  Yes, with the level set at 84 db (according to my radio shack thingy) the SIT-1 delivered real bass drum whacks but the L2i needed more juice.  Like four up clicks on its 64 step remote volume control (to about 89 db).  Voila, like the magical Harry Potter paintings that suddenly become three dimensional, you are immersed in a musical sound field with no lack of bass. (Before accusing me of hyperbole read some of the reviews of the L2i or the separates it's the hybrid of.  And remember those reviewers don't have Nenuphars!)  So, yes, it's true the SIT-1 comes to life at lower volumes and is the perfect early-morning-before-your-house-mates rise amp (and what an amp).  But when the house is yours, you'll want to plug in the L2i and fly.  

But what about the L2i in DHT pre mode driving the SIT-1's?  Do you get the best of both worlds?  No, but you get a gorgeous sound.  Something I would be head over heels for if I hadn't heard the L2i going solo.  I have to do a little more A/B work against the XP32 to give you comparative details.  

Hi Stephen, 
Thanks for the update. It seems clear that the Vinnie  Rossi hybrid is a fabulous match with the Nenuphars. It's gratifying to read how happy you are with this current system  set-up.  I believe that you will remain in joyful musical bliss for years to come. It's an achievement to get your audio system to a point where it all clicks for you.
