Labyrinth Speaker

 I have built a unique speaker named "labyrinth" .
This is an extension of the "angular spiral" concept devised by myself.
Anticipated advantages of the rabyrinth are :

(1) Elongated sound passages.
(2) Prevention of standing wave with slanted fins.
(3) Decrease of high frequency by repeated cycles of expansion and reduction of cross-section area of sound passages.

The sound is very good with clear and strong low frequency region.
I think the labyrlinth speaker may not belong to TLS because it dose not use dumping material and dose not resemble in impedance characteristics.
My previous home pages are discarded because this labyrinth speaker is too good.

All 22 fins have the same shape with 30 degree slanted cut end.
15 mm MDF is used for whole cabinet.
2
At the start, divider plate is bonded at the center of the side plate.
