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

Hi @djembeplay sounds like a great project. What design are you considering and type of wood? Just in case you are not aware, the plans on the Cube website are different to what they use for their own complete builds. 

Yamamotos will be a great match I would think.

I believe that your Yamamoto 45 amplifier will be a very good pairing with the Nenuphars given the intended use.

Hi @toetapaudio - glad to hear your endorsement for the Yamamoto.  For the cabinet, I'm planning on building the plan on their site that's labeled "F10 Neo / F10 DIY cabinet" at 1000mm x 600mm x 320mm.  This looks like the closest of the two designs they published to what they are using in the Nenuphar.  I'll build everything exactly to plan, except my material may end up being slightly thicker -- I'm thinking about using 3/4" stranded or vertical bamboo ply, built over an inner box of 1/4" or 3/8" Baltic Birch, with a thin silicone layer between the two materials... sort of a 'ply - spring - ply' layer.  This will let me build the inner box with less attention to aesthetics (exposed fasteners, rough edges, etc.), while creating a form with exact right angles to layer the bamboo on top of.  Those are the plans for now at least... Summer is still a ways off, and parable quotes of mice and men applies suitably here.

Like you, I did notice that the Nenuphar is built differently to the published design I'm looking at.  The two major differences I can see is that the Nenuphar is 500mm deep instead of 600mm, and it's bottom ported instead of rear ported.  It's also listed as being 5mm higher, but this might be taking the gained height of the front floor spikes into account.

I do wonder why there is a difference between the Nenuphar and the DIY plans... I'm planning to write Cube to ask them.  Perhaps they have a proprietary design in the Nenuphar that they don't want to publish for marketing reasons, which would be understandable... or, perhaps they just updated their design at some point and haven't likewise updated the DIY plans... shrug.

@charles1dad Thanks also for fortifying my thinking about the Yamamoto -- we in the low watt SET camp have to tread very carefully with our speaker selections, so it’s good to know I’m not ’off in space’ thinking this would be a nice combo.

@djembeplay thanks for the details. Probably you know that every material used in audio has a sonic signature. One can test by introducing different materials under equipment and listening to the change in sound. I haven’t tried building cabinets yet but considering. Some say spruce is better than birch ply, mdf giving the least good results. Apart from the plans on Cube, I understand that Scott at Woden Designs has undertaken some designs for Cube drivers.
