05
A network speaker implies the ability to send audio to such a device from a network connection, usually over an Ethernet network or the Internet. In many cases this type of speaker also contains digital signal processing (DSP) to provide the audio crossover and other tonal functions that exist in conventional speakers.
Network speakers are also known as IP speakers. In many cases the IP speaker is created from an IP audio endpoint — a device with the requisite network connection and ability to process audio packets, but without the actual physical speaker portion — that provides amplified audio to a conventional loudspeaker or unamplified audio (i.e. line-out) to an amplified speaker or system.

Frequency Range of Network Speakers
Most network speakers have a low frequency of around 60-70 Hz. Larger units with 15” drivers will reach low frequencies, while those with 10” or less LF drivers will roll off closer to 100 Hz. The high-frequency range of such devices usually extends up to 18 kHz.
Smaller format speakers with very low-mass HF drivers will have range extension above the high-power systems.
They have heavier diaphragms to accommodate their power requirements. The low-frequency range of these systems will not require them to do the work independently on the bottom end. They might overlap the subwoofers or be crossed over above their LF cutoff and relieved of low-frequency transmission.
