Live Sound Line-Array Myths
- Brand-name Line-Arrays are best.
You pay extra for their advertising.
- Off-the shelf Line-Arrays are best.
You maybe better served by Venue Specific Arrays.
- Line-Arrays are too expensive.
One-Box Line-Arrays with built-in Subs are affordable.
- Line-Arrays have to be rigged overhead.
Compact Line-Arrays can be wall mounted and larger arrays can be stage stacked.
- Small Subs are just as good as larger subs. Size matters. The box/enclosure size is a primary factor
(along with driver max. power & Xmax) in predicting how low (in frequency) &/or how loud a woofer can play.
- How well a system covers a venue depends on its power rating.
Power rating does not relate to system coverage. A more important spec is dispersion (given in degrees).
- You can judge a system’s power by its specification in watts.
I hate to be the bearer of bad news, but many wattage specs are meaningless because they rarely state the testing protocol, the efficiency of the speakers, and the amount of distortion that’s considered acceptable (for example, an amp could be rated at 150 watts with 1% distortion but at 200W with 10% distortion). Without knowing this kind of information, you’ll never be able to compare apples to apples—it would be like measuring gas mileage for one car speeding down a highway, and another coasting downhill in neutral.
