Thanks to the speaker's DSP technology, the tough, long-throw 8-inch aluminum driver can generate maximum sound pressure levels at any planned frequency, with variances never reaching more than 1.
General information: The directive on the protection of workers from the risks related to exposure to noise at work (86/188/EEC) requires that workers should be provided with hearing protectors if the noise exposure is greater than 90 dB(A) or, in the case of impulsive noise, the maximum sound pressure level is greater than 200 Pascal.
