HALLMARK OF A GREAT SPEAKER. There are 4000 speaker companies worldwide. Ony 10% of those companies make their speaker cabinets and driver's in house. Out of those 10%/400 companies, only a handful rise to the top as the best sounding speakers, since they all use the same parameters. Very heavy multi-layered cabinets with internal ladder or cascading braces, isolated chambers for each of the drivers, and multiple crossovers with large power caps. Magico's top models use capacitors the size of a coke can. Awesome to look at. The final part is a damn good anechoic chamber with state of the art measuring equipment that will result in a razor flat frequency response top to bottom. When deciding on the right amount of amplifier power, find out from the engineers at the speaker company whats the maximum continuous power limit that the drivers and crossovers can handle and divide by two. If they say a 1000 watts, use a 500 watt amp. Remember, not short term peaks but continuous power. This will greatly reduce heat in the voice coils and crossover components and they will operate at cooler temperature's resulting in the best performance from your speaker and eliminate clipping.
