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

Stephen, thanks for the additional details and information.

For clarification, I was referring to the area [open and unrestricted on all sides, in stock configuration/setup] for the "air" / "energy" generated by the driver to exit from the bottom ported transmission line.

In your setup, the energy would only ’exit’ on the left and right sides of the speaker bottom. From what you have heard and shared, you are clearly very happy with the results.

My concerns are around restricting the outflow of air/energy AND limiting it to a left/right dispersion.

I know I will not know, one way or another, unless I try it out.

With my setup:

- the delta in performance upside was far greater with the Eden Sound spikes vs. the stock spikes/rubber bumpers [on my hardwood flooring]

over the,

- the delta from the speakers with the Eden Sound spikes on the Townshend Platforms 

Illustrated another way:

Stock on floor <<<< Eden Sound on floor < Eden Sound + Townshend

This may support Max’s point to couple as much of the speaker contact areas to the platform, OR, it may point to the stock spike/bumper setup being subpar and easily improved upon (in my case with aftermarket spikes, front and rear).

I’m open to trying your method, however, it will have to wait until the meniscus tear in my knee is resolved. : )

I’ve added two photo closeups on my virtual system page, for visual reference.

Hopefully the photos help clarify my prior post (above).

I believe the photos (clearly) illustrate the ’open’ area, across the entire speaker bottom.

The spikes are from Eden Sound.

The platform is the Townshend Audio Seismic Isolation Podium.

Meniscus tears are no fun.  Lived with one far too long.  Wish I'd gone to the surgeon first thing.  I suppose that's deemed an elective surgery right now?  Good luck.

My bad, I didn't understand your point at first.  Yes, the wood strips do close off the space front and back between Platform and bottom of speaker.  And you're right, that space was no doubt tuned for the size and output of the port.  I'm going to do some A/B listening with and without the wood strips to see if I can get a handle on what it's doing to the bass. (Ok, I have to admit when I first put the wood under the speakers my ears gave a double thumbs up and they haven't moved since.) But I have to say when I was listening to the Symphony Fantastique the other day (at near live level) I was amazed by the depth and reverberation of the kettle drums...so I don't think it's diminishing the bass...

On another note, I ran into the Townshend Super Tweeters I used to use with other speakers in my storage closet.  I think I'll experiment with those.  I remember SE effusing about the addition of omnidirectional super tweeters (forget the name right now) on top of the Nenuphars.

This makes me sound like I'm unappreciative of the Nenuphars as is.  Hardly.  It's more like having a hyper sensitive instrument that responds to everything it interacts with.  Fun stuff.  

Has anyone tried a Valvet amp with a Nenuphar?

@rwpollock   I've had an interest in Valvet for some time and came close to purchasing the A4 instead of my Pass Labs 30.8 to drive my previous speakers.

I just took a quick look at Valvet's website but couldn't find the information I was looking for.

I recommend reaching out to Alfred (the importer/retailer) and Valvet directly to find out the following:

- Feedback (preferably zero; or very low levels)

- Damping Factor (the lower the better)

If the above holds, I can see Valvet being an alternative along the lines of First Watt, which (as you probably know) has proven to be a terrific pairing with the Nenuphars.
