Cavity sound pressure level is a very important measure when dealing with the design of resonator based power generating sound absorbers and sound diffusers. This paper presents results from experimental study of the performance of the second generation iARG-X2 power generating Helmholtz resonator. The use of specific X-shaped extention for the cavity junction could encrease the sound pressure inside the cavity up to 16 dB above of the similar resonator without extention. The experiment was conducted with various types sound source, i.e. single tone, dual sine, and random noise that all resulting similar cavity sound pressure increment pattern. It brings new possibility for the development of power generating sound absorber and sound diffuser which is very usefull in green modern life style both for indoor and outdoor noise control applications
