Page 4: Safety
Do not use Electro-Voice loudspeakers in an environment where temperatures are below 0°C (32°F) or exceed +40°C (104°F). Never expose an Electro-Voice loudspeaker to rain, water, or high moisture. Electro-Voice loudspeakers are easily capable of generating sound pressure levels sufficient to cause permanent hearing damage to anyone within normal coverage distance. -
Page 5: Suspension
Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of suspending objects overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into account all current national, federal, state, and local laws and regulations. It is the responsibility of the installer to ensure all loudspeakers are safely installed in accordance with all such requirements. -

EKX Passive Loudspeakers Suspension The EKX-12 and EKX-15 enclosures have eight (8) M10 threaded points; six (6) points on top of the enclosure and two (2) points on the bottom. Forged shoulder eyebolts rated for overhead suspension may be used to suspend an individual loudspeaker, such as the EBK-M10 accessory. - Page 15 Replace the M10 screw with the fender washer and eyebolts. Notice! If the eyebolts are removed reinstall the screws. If the screws are not reinstalled air leaks occur in the enclosure, resulting in undesirable performance.

Do you have a question about the EKX-12 and is the answer not in the manual?
Questions and answers
If specification requires sensitivity 126 db (spl), how the difference for 95 db(spl) can affect to operation for the speaker?
A sensitivity rating of 95 dB SPL means that the speaker produces 95 dB of sound output with 1 watt of input power at a 1-meter distance. In comparison, a specification of 126 dB SPL represents a significantly higher output level. A lower sensitivity, such as 95 dB SPL, requires more amplifier power to achieve the same loudness as a speaker with a higher sensitivity, like 126 dB SPL. This means the EKX-12 would need a more powerful amplifier or higher input levels to reach louder volumes compared to a speaker rated at 126 dB SPL.
