a variable low frequency absorber unit which uses a sliding opening and each of the closed panels act as membranes further enhancing the absorption. the interior cavity is damped with an MLV membrane and light weight insulation. the edges of the unit keep is about 1/2" (12mm) off the surfaces. built using 15/32" (12mm) plywood, 3/4" (19mm) cleats, 7/8" (22mm) trim. #1D #2D_Array #Absorber #Absorption #Acoustic_Treatment #Acoustics #Audiophile #Bass #Bass_Trap #Binary_Amplitude_Grating #Chinese_Remainder_Theory #Cloud #Commercial #Composite_Panel_Absorber #Cubits #Curved_Absorber #Design #Diffuser #Diffusion #Dispersion #FreeFlow #FreePress #FreeStand #Frequency #Gobo #Helmholtz #High_Fidelity #High_Frequency #Home_Theater #Low_Frequency #Maximum_Length_Sequence #Mid_Frequency #Panel #Poly #Polycylindrical #Primitive_Root_Sequence #Private #Professional_Audio #QRD #Quadratic_Residue_Diffuser #Recording_Studio #Reverberation #Slat_Resonator #Sound #Space_Coupler #Space_Coupling #Spatial #Treble #VNP #VPR #Wave_Diffuser #Wave_Guide #WaveForm #Wavelength #Window_Gobo
