Increased bass radiation from linoleum carpet wooden floor base to linoleum tetrahedron fullrange speaker

(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.)


Signal path:


Athens FM radio stations - JVC 70's 9425W FM radio and its great bass boost power amp - Tesla TVM ARX - 130 - 25/4 drive unit - linoleum triagular pyramid enclosure standing on linoleum carpet - 2m x 1m of linoleum carpet - wooden floor - bedroom - listener's ear-brain (2 listeners)


It was observed by Vicky that it sounds great with spectacular clearness, naturalness and great deep bass.


It was observed by Vicky that the floor vibration may be part of the bass sound.


Linoleum triagular pyramid was lifted by hand and bass decreased.


Then speaker was placed in bare wooden floor. Bass increased a bit.


Then speaker was placed again on top of linoleum carpet sheet on top of wooden wood. Bass increased substantially.


It seems linoleum not only vibrates but gives a deep resonant quality at sound without reasonant artifacts. Just a broad band flat frequency response enhancement.
