An audio system includes amplifying with distortion via a first amplifier electrical audio signals from a sound source, such as an electric guitar, for example, to obtain a desired tonal quality in the sound produced from a first loudspeaker driver by the amplified electrical audio signals, simultaneous with applying electrical signals from a piezo film transducer attached to the cone of the first loudspeaker to a second amplifier having a flat response over a desired frequency range, and adjustable low and high frequency rolloff, for driving a second loudspeaker to produce desired perceived tonal quality at relatively low sound pressure levels, with the volume of the sound from the first and second loudspeakers being adjusted to match the acoustics of a room in which the audio system is operating.
