Systems, methods, and processing are provided for adjusting an audio playback signal to adjust a temporal alignment of content within an audio signal. The audio signal is received and filtered to provide an adjusted audio signal. The adjusted audio signal includes a delay in a first range of frequencies relative to a second range of frequencies, and the adjusted audio signal is provided to a sound reproduction system, such as an amplifier and at least one acoustic transducer.

Audio system with adjustably delayed frequencies

A vehicle loudspeaker system is provided. The system includes a vehicle body having a trunk floor pan, and a trunk floor that covers the trunk floor pan. The trunk floor has an upper surface and an opposite, lower surface. An electro-acoustic transducer is disposed between the lower surface of the trunk floor and the trunk floor pan. The transducer includes a diaphragm that defines a first radiating surface and a second radiating surface that is opposite the first radiating surface. The electro-acoustic transducer also includes an electro-magnetic motor for driving motion of the diaphragm along a motion axis. The transducer being arranged such that motion axis is within 45 degrees of parallel with the trunk floor. The system also includes a duct that is configured and arranged to direct acoustic energy radiated from the first radiating surface to a region above the upper surface of the trunk floor.
