Floor-Standing
Floor standing speakers are generally built to produce the most accurate high-end frequencies, midrange frequencies & low-frequency sound reproduction. This is due to the design having more speaker drivers to handle specific duties.
Standmount/Bookshelf
Some bookshelf speakers are larger in size and can be placed on speaker stands, hence their name standmount speakers. These as mentioned tend to be bigger versions of bookshelf speakers and offer up a more complete and larger sound for your money.
Headphones/Headphone amp
A headphone amp is a relatively low-powered amplifier that raises the low-voltage audio signal from a source device (be it a turntable, PC, or smartphone) to a sufficient level such that it can be converted (or transduced) into sound waves by the speakers inside your headphones.
Subwoofers
A subwoofer is a crucial component of a complete audio system because it delivers lower frequencies between 20 – 200 Hz, which traditional two-channel or surround sound setups can’t produce on their own. In fact, subwoofers are responsible for the . 1 in a 7.1 sound system to deliver all the low-frequency effects
Center Channel
Center channel refers to an audio channel common to many surround sound formats. It is the channel that is mostly, or fully, dedicated to the reproduction of the dialogue of an audiovisual program.
Surround Speakers
Surround sound is a technology that is used for enriching the quality of audio reproduction for listeners by using additional audio channels. Unlike screen channels, the sound produced by surround sound technology is from a 360° radius in the two-dimensional plane.
On-Wall
on-wall speakers are mounted front-firing with the woofers pointed horizontally across the room, while ceiling speakers are mounted down-firing from the ceiling above.
