Electro-Voice Premium Surface Mount Speakers manual Specification Questions

In mono systems (with the inputs of the subwoofer paralleled), the amp views the loads hooked up to the Left and Right satellite outputs as being in parallel with each other. Make sure the amplifier can run loads of less than 4 ohms in this situation.

What are some techniques to properly balance the levels between the subwoofer and satellites?

The required sensitivity balance between the subwoofer and satellites varies by the musical requirements of the application. A sports bar or health club for example might require much more bass content than does a low level background music system.

Sensitivity of the satellite section varies depending on the particular satellite model chosen, the number of speakers employed and the wiring configuration. Higher satellite sensitivities result in less relative subwoofer level.

It’s generally best to position the subwoofer after the rest of the system is installed, changing its location to achieve the optimum bass level. The acoustic volume level of the subwoofer can be raised or lowered by moving its position within the room. Beginning at a corner junction in the room you can enhance bass output by moving the subwoofer closer to the ceiling or floor; you can reduce apparent bass output by moving it out onto the center of a wall. You can decrease bass output further by suspending it in the middle of the room.

Specification Questions

Are the EVID full range speakers protected against excessive input power?

Yes, protection circuitry is included inside all the 8-ohm models. This circuit gives full- range protection including the woofer and tweeter. The “t” versions are current-limited and fully protected by the transformer.

Can the EVID models be use outdoors?

Yes, the full range models are all “weather resistant”. They pass MilSpec 810 and are IEC rated as “splash proof” (IEC529 rating of IP-x4). If possible, it is best to install the units under an overhang maximize long term performance.

Although not always needed, further moisture protection can be obtained by using the weatherized terminal covers when the EVID 4.2 and 6.2 units are used outdoors. These covers are simple-to-use and protect the input terminal panel. The cover installs over the existing input cup, providing a sealed gland-fitting entrance to further protect the input panel against the elements. The cover is available in black and white and can be painted.

How are the EVID full range models tested for weather resistance?

All EVID full range loudspeakers feature weather resistance design criteria which allow them to pass MilSpec810 and IEC529 specifications. These specifications provide tests to determine outdoor capability in severe climates. Five separate test sessions are
