The acoustic suspension speaker system was designed to allow a speaker of a smaller physically size to produce a higher level of low frequencies. When introduced in the later part of the 1950s, the acoustic suspension speaker principle astonished the loudspeaker industry. This design incorporates a sealed box speaker cabinet using the air trapped inside to provide a pillow or cushion, prompting more linear movement of the low frequency speaker. An acoustic suspension speaker is found to produce sound more accurately and allows sound to move a greater distance while still producing efficient low frequencies. An acoustic suspension speaker system also requires a higher level of amplification to function efficiently.
The best performing acoustic suspension speakers depend on specific factors to produce the most efficient output. First, the amount of trapped air inside! ...
