On linoleum triangular pyramid speaker, linoleum radiates the bass guitar sound only

(Later addition: The linoleum triagle pyramid speaker may have a less flat frequency response than the linoleum cube Auratone 5C type speaker. More experiments needed.)

But this is not strictly true. When for example electric guitar is not playing at some moment of a track, a bit of other frequency content can be heard too, for example midrange but it is bit of a bad colored quality such as on the cube speaker.



Τhe relatively large areas of vibrating linoleum are efficient radiators of low frequency content.
