Various implementations include speaker systems. In one implementation, a self-powered speaker system includes: a self-powered speaker system, having: a first module, including: a processor; an audio signal and control connector coupled with the processor and enabling audio signal and control communication between the processor and another module in the speaker system; a dedicated power supply for the speaker system; a front end backup power supply; and a power connector coupled with the dedicated power supply and the front end backup power supply, where the first module and another module in the speaker system each include an amplifier module.

In one implementation, a self-powered speaker system includes: a first module, having: a processor; an audio signal and control connector coupled with the processor and enabling audio signal and control communication between the processor and another module in the speaker system; a dedicated power supply for the speaker system; a front end backup power supply; and a power connector coupled with the dedicated power supply and the front end backup power supply, the power connector enabling input power to the dedicated power supply and output power from the front end backup power supply.

A loudspeaker includes a cabinet, a coaxial transducer assembly, and a waveguide. The coaxial transducer assembly includes a first transducer and a second transducer that is coupled to the first transducer and arranged such that respective motion axes of the transducers are coaxial. The waveguide is coupled to the first transducer and configured to provide an acoustic impedance match between the first transducer and free air. The waveguide includes a first plurality of apertures that enables acoustic energy radiated from a first radiating surface of the second transducer to pass through the waveguide and merge with acoustic energy radiated by the first transducer. The first plurality of apertures extends through an expansion region of the waveguide.
