Elk Training, Week 5 Interior Speakers

What is a speaker? A device that broadcasts a sound generated by a separate electronic device; such as a siren driver, voice driver, or any other type of audio input. A speaker can play sounds, music, or voice depending on what it is given. It generates no sound without input. Think of your stereo speakers – they can play voice, country music, classical music, rock ‘n roll, etc., depending on the input they are given.

When would you use one? When you need to provide voice messages, sounds, or entertainment with the following type systems: security, access control, paging, intercom, music & sound, emergency alert, etc.

What types of interior speakers are available?
Flush mount
– once mounted, the bulk of the unit is recessed in the wall.
Surface mount
– mounted to the surface of the wall.
Box Speakers
– shelf or stand speakers, generally for hi-fidelity

What does the wattage rating mean?
Wattage rating is simply the maximum power a device can safely handle continuously; the higher the rating, the more power the unit can handle. Wattage rating is also relative to the clarity of the sound reproduction. If you want voice reproduction, you should select a speaker rated at no less than 20 Watts. High fidelity speakers are generally rated at 50 Watts and above. The wattage rating is usually 10 to 15 Watts on interior, security related speakers.

Esthetics: Most general purpose interior speakers are plastic with grilles in the front to allow the sound to exit. The plastic generally “yellows” with age and prohibits paint adhesion. Painting over the grille could also block the sound portal, diminishing the effectiveness of the speaker.

What makes Elk interior speakers different? The wattage rating on Elk interior speakers is 20 Watts, providing better voice clarity for voice messages and longer service life with siren drivers. They are not recommended for hi-fidelity applications, but general voice messaging & sound reproduction are very good. Along with the traditional “grille” speakers, Elk offers a premiere line of speakers known as the “Echo series”. Our “Echo series” is reverse engineered so the grille is in the rear of the speaker and utilizes the wall as part of the sound chamber, actually providing a better sound. The plastic is porous to allow paint adhesion and the grille is unseen, meaning they can be painted or wall-papered to match the décor of the room. They seem to “disappear” into their surroundings. All units are surface mounted so they require less installation time.
