A flat panel sound radiator (11) with enhanced audio performance, said flat panel sound radiator (11) comprising: a panel (12) having a core (18) of a first material sandwiched between facing skins of a second material (19, 21), said facing skins (19, 21) being secured to said core (18) with an adhesive; an exciter (22) coupled to said panel (11) for imparting vibrations corresponding to audio program material to said panel (11); said second material having a Young's modulus and a tan delta each sufficiently high such that said flat panel sound radiator (11), when subjected to a spectral contamination test, exhibits a signal-to-noise greater than 40dB for an input signal of 85dB within a frequency range from about 1 kHz to about 10 kHz.
