An Auratone 5C is currently not available for comparison.
The first made is larger ie 8 x 8 x 6 inch cubed.
It is a carton box.
It sounds more treble harsh, possibly because it emits less mid.
Possibly also because carton absorbs less low mid frequencies than linoleum having elastomer hysteresis properties.
The second made is exact dimensions as Auratone ie 6.5 x 6.5 x 5+3/4 inch cubed.
It is made of linoleum.
There is more mid, more focused sound. Possibly due to the smaller dimensions. The inventor of Autatone must have tried so many different dimension boxes.
There is balance with low and treble perception.
The sound is less harsh possibly due to Linoleum killing or attenuating box wall reflections thereby standing waves.
It sound soft and smooth.
This is the first Linoleum Pleiades Auratone 5C type speaker.
Apparently some perhaps somewhat deeper bass than anticipated from experience is produced by these speakers from thin sides, back side panel vibration thereby acoustic radiation? This is from memory comparing previous experience with more conventional wooden boxes. Bass is not much but sound is balanced on the linoleum example and the speakers have not yet been tested with a power amplifier. (Attention to hearing protection from high SPLs).
Speakers were connected in turn directly to iPad's mini, headphone out on one channel while listening from YouTube to great music tracks.
Frozen - Madonna for example sounds with so natural voice. Nothing forward, treble but not hyped treble, like Madonna being in the room.
The speaker with Linoleum is not perfect. There are still some mid reasonances. More investigation needed.
This guy's in love - Herp Alpert sounds without mid problems
