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

@toetapaudio I hear you on spikes, generally speaking. For example, I am using Ingress Audio Engineering's RollerBlocks throughout my system.

I will note that moving from the stock spikes and rubber bumpers of the Nenuphar to Eden Sound brass spikes (front) and brass hemi-spikes/spheres (rear) made an easily identifiable and immediate positive difference.

@khragon   I recommend trying the above since (from your photo) it appears you are using the stock spikes / rubber bumpers. The Eden Sound solution, or equivalent, is a low cost change that (in my case) paid positive dividends. An easy first move to squeeze more performance out of the Nenuphars.

[Note: I'm using the Eden Sound spikes 'solution' on Townshend Audio Seismic Platforms]

It’s not obvious but the footprint of the iso device must be large to obtain the required lateral stability for objects with high center of gravity. Sure, you could make the springs stiffer with a smaller footprint but then the device wouldn’t isolate as well.

Thanks @geoffkait  +1 and noted.

@stephendunn  Thanks so much for the detail you shared around your experience and insights with the Townshend Seismic Platforms. I still need to work on optimizing placement / positioning / toe-in / tilt etc.

Your results and findings are very encouraging.

@khragon Likewise, looking forward to what you end up preferring re. placement etc. in your setup.

@david_ten I heard a Grandinote pre DAC /amplifier combo at the workshop and I was thoroughly impressed. One of the best set of front end electronics I have heard. Mind you, I've heard the Terminator DAC in a shootout - it's a good bit of gear too.

We can supply Nenuphar drive units World wide and are looking into cabinet designs customers can use. We can also supply Townsend Podiums to use with the Nenuphar’s.
