This two way design features the same great Silk dome tweeter with Perlisten's custom paper pulp 6.5” woofers as their in-walls and highly regarded in-room speakers. This enables a flat frequency response angled for 30 degree main listening window with off axis and power response to match Perlisten's R-series speakers for flawless timber matching needed for true immersive audio. An open back speaker for shallow depth installations where sound isolation is not a design criteria. Better coverage for even response in any application from Home Theater to better coverage in your kitchen with no compromises!
