A reminder......the Neo 10 drivers are $6500 the pair directly from the US distributor. You can build an even better box for way cheap. However, if you mounted it on a four foot high by 2 foot wide open baffle....with four foot by one foot wings going straight back on each side......you would have even better sound......and you would still get flat to 40hz bass. You could buy some 13 ply baltic birch three quarter inch plywood and use three layers with green glue in between each layer.....pretty darn dead.

For even better sound (whether in a box or open baffle). You can hardwire some great sounding wire directly to the voice coil wire (the point where the voice coil wire is soldered to the banana jack). Then you solder that wire (either hanging out of the box.....or dangling off the driver in open baffle) directly to your speaker wire......so there would be no speaker connectors what so ever......this will blow your mind. You an also solder a Ground Enhancer directly on the negative voice coil wire, as well for even more info. WAY, WAY more transparent. or you can keep your speaker stock and enjoy the veiled sound.....he he. You can do what I suggest and put it all back to stock later on when you sell the speaker (if ever).

You guys have never heard your speaker......you do the above and you will cry and weep it will be so good.  One of you wants to do it.  One of you is not a sheep.  One of you wants to get sound to die for.....all it takes is one person willing to do it.....costs really nothing to hardwire.......just some labor.....and you can put it all back to stock without anyone ever knowing.  Don't be a wimp.....he he.  You can do it.  I will talk you though it on the phone, if you like....really.  I want you guys to weep with joy over your sound.
ricevs Do you own speakers made with Cube Audio drivers or similar widebanders?  Do you know anyone who owns complete (with cabinet) Cube Audio speakers who has replaced the wire as you suggest?  Do you have a recommendation for "some great sounding wire" that would make us "guys weep with joy over your sound"?  Pls suggest what would be the very best wire regardless of cost.  We don't have to buy much and while my Nens do make me weep on occasion I could handle more.
No, do not own Cube speakers nor know anyone who does.  No one in the world has done what I suggest......you could be the first!  I do know someone who has done this to his $1200 a pair Lii Silver 10 speakers (mounted on the open baffle described above).  Yes, I have done this to many speakers and make my own speakers and have since the mid 70s.  I have modded and manufactured gear since the late 70s.  I bean around the block.  People will argue all day about what is the worlds greatest hook up wire.  I really don't know.  But any great wire will work fantastic in the scenario described.  It is the removing of the banana jack, the banana plug, the WBT connector and (if possible) your spade on your speaker wire that will make the most difference.  Of course, you want great wire....here are some suggestions:

Parallel single strand PCOCC Chris Venhaus wire
Parallel silver gold Mundorf wire.
Neotech copper litz braid wire....parallel several 20 gauges or get some 14 gauge from Zen Wave.

I like the tempo electric solid core silver in Teflon (and use VH audio solid core silver in my interconnects and components).
For Nenuphar (reg or mini) owners, how far apart are your speakers and do you tow them in? I have minis and I just moved. My new room is bigger than the one before. I’m working on setting up the speakers and they’re very “beamy” at this point where the sound seems to coming right from the drivers. I just moved them further apart with almost no toe in and it’s better but still a bit beamy. Maybe I’ll move a bit further still. Just wondering how everyone else is set up. Thanks.
