LII AUDIO 2025 New FAST-15 Full Frequency Speaker 15 Inch 8ohm/50-80W Unit (1PCS)

What is a full-size baffle, such as a horn mounted baffle with F0=40HZ? The full wavelength of 40HZ is 7.5 meters, which means that a 7.5-meter baffle can block the low-frequency waves on the back of the horn to prevent low-frequency short circuits (this is the function of a baffle). Of course, sound waves have peaks and valleys, and even a quarter of them can be blocked. That is, a baffle width of 1.875 meters is required for 40HZ, which is called a full-size baffle. But this size cannot be achieved in many environments. Some friends only have a 60 centimeter baffle, so how much bass can be produced? It can be calculated. This is what we call a small baffle. The requirements for choosing F0 are not very high, and the listening experience is quite good. Of course, both QTS values and amplifiers can improve low frequencies, but there are limitations.
