resistance - Can a speaker be damaged but not blown

A more efficient speaker will have a higher number and a less efficient speaker will have a lower number. Putting it all together. So, let's assume we have a speaker with a sensitivity of 90 dB @ 1W/1m and a power handling capacity of up to 100W. If that speaker is powered with 1W of power, it will generate 90dB when measured at a distance of 1

With a loudspeaker, the mass of the moving parts, and the stiffness of the suspension (surround and spider) are the key elements that affect the resonant frequency. As a general rule of thumb, a lower Fs indicates a woofer that would be better for low-frequency reproduction than a woofer with a higher Fs.

We want the subwoofer to be a natural extension of our left, right, or center speakers in both volume and frequency. For example, let's say the subwoofer plays from 150 Hz and down and the main speakers in the system work from 40 Hz and up. Between 40 Hz and 150 Hz, both the main speaker and the active subwoofer are reproducing sound.
