Question: does anyone have experience comparing Voxativ with Cube? What were your impressions?  Thanks!

If you want to make any cube speaker way better then do this:

Remove the driver and the binding posts.

Solder super wire directly to the voice coil wire.....no longer usng banana plugs into the banana jack....solder the speaker wire to the end of the banana jack (the very same point the voice coil wire is attached)

Run this wire directly out the back of the speaker about one foot and strip about one inch of wire and bend it around a quarter inch drill bit to form a loop and tin the bare wire loop with solder. Strip the wire after you have soldered the other end to the driver and reinstalled the driver.

Also, solder a Ground Enhancer ($30 a pair) to the negative voice coil wire (speaker wire and ground ehnancer are soldered together at the same point).

Put a Bybee Quatnum Clarifier ($100 each) on the back of the magnet of the driver.

Reinsall the driver.

Pull the any slack in the wire though the back holes and then cut the wire so you have about one foot of wire hanging out....then strip and tin and bend the wire..Attach your speaker wire (either bare wire or spade) to the wire coming out of the speaker using one quarter inch nylon bolts, thick washers and wing nuts (very cheap).

Turn on music......pee in pants.....cry and laugh. Now you have Nenuphar mark VII

By removing the banana connection at the speaker and removing the binding posts (essentially hardwiring), adding the Ground Enhancer and Bybee thang and using better wire than what is in the speaker you will hear things you never dreamed of. Much more extended, real, warm, dynamic, larger sound, much lower noise, more ambience, space, well..everything. Total cost about $260 plus some super wire...say $350 total.... Time.....about 3 hours....one hour and a half per speaker....being very careful You use a wire that is much longer than you need to you can put the wire through the box and have it hanging out the back......because it is now so long....you can work on the driver directly on a small bench in front of the speaker....another way to work on the speaker would be to lay it on its side on a padded table....then you can work on the driver right next to the cabinet.

Who will be the first to tweak a Nenuphar? Everyone hotrods their cars.....no one would think twice about taking their brand new $70k Corvette into a modders place and having an even bigger supercharger put in, etc. for another $25K to get another 2 -300 horsepower. Yet, no one in the world will spend $350 to upgrade a $16,000 speaker? We are such wimps....he he. You can always put it back to stock and no one will ever know.....Of course, once you have heard it modded you will never sell it.....ever.....

What is so cool about any single driver speaker is its simplicity...no fricking crossover......but still...every single thing you do (or don’t do) affects the sound....big time.....these mods are simple...yet highly effective.

Please read this review on what the Bybee thangs can do:

Please, enjoy this moment and every moment that exists.....it is your right to choose love and joy all the time. The more you choose something and live it....the more you become that quality. You want to feel better? Than let yourself feel incredible right now...and keep choosing it every now.

Blessings and love.

Thanks David for the advice.

ricevs, I’ve been there and done it 30 or so years ago. I agree it does make a difference direct wiring. As a Cube dealer I’m not going to recommend as this would inevitably disqualify the warranty. It might be possible to specify when ordering but doubtful? Manufacturers make compromises for commercial reasons.

I’m not convinced about Bybee though, I have some but not tried with Cubes. 

@ricevs what is this super wire ? Any link ? I have contemplated changing the internal wire of the Nenuphar to a better solid silver wire but just didn't get to it. The internal speaker wire looks a bit flimsy and think a better wire could definitely benefit.
 

 

 

Btw, I have been using a pair of Fidelium speaker cable for some time now with great results.

Also have been playing with a pair of SR latest CTD (Carbon Tuning disc) - placing a purple disc on the speaker cable did not yield any change with the Nenuphar, which is contrary to what others have reported with speaker cables. Might move them into the speaker, near the banana post to see if the results are different.
