This is a list of notable manufacturers of loudspeakers. In regard to notability , this is not intended to be an all-inclusive list; it is a list of manufacturers especially noted for their loudspeakers and which have articles on Wikipedia.
The System Fusion communication protocol enables devices to analyze an incoming signal and automatically determine if it is using C4FM or conventional FM mode. System Fusion also enables data transfer at full rate with speeds reaching up to 9,600 bits per second. [5] Yaesu is the only company with System Fusion-enabled devices.
The Yaesu FT-857 is one of the smallest MF/HF/VHF/UHF multimode general-coverage amateur radio transceivers. [46] The set is built by the Japanese Vertex Standard Corporation and is sold under the Yaesu brand. [47] The FT-857 is developed on the FT-897 and MARK-V FT-1000MP transceivers. [46]
For low order systems however, reconstruction can easily fail entirely when line-of-sight to speakers is blocked, which has led to odd seating arrangements in listening tests. [ 1 ] With-height systems usually provide more unhindered lines-of-sight per direction for a given audience, which might increase their robustness.

This system has a characteristic mass and stiffness, and a resonant frequency at which the system will vibrate freely. This frequency is known as the free-space resonance of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity.
