Rod,
"So anyone that has a cap that says it improves their sound system you can now inform them of their weaknesses!" That is not entirely true.... There are new Ultra-capacitors that can store EXPLOSIVE amounts of energy. If these are placed close to the amplifier, then they can provide extra power when the amp is pulling a lot of current, then re-charge when the amp is pulling less current. They are more than a filter, they are an energy source for load leveling. Stu |

An amp has an array of capacitors that store the amount of voltage it needs to produce it's maximum output, adding another cap before these is just a waste of time, the battery that fills this cap either fills the additional caps reserve, or the amps reserve first, now I know which one I would rather have topped up instantaniously, and it's not the external cap. In fact because the battery is desperately trying to fill the external cap the amps' caps are being deprived of the power they need so in fact it is doing the complete opposite to it's purpose.. Some of my friends run 15kw systems doing 20hz at 155db and the only caps in their cars are on their heads (IMG:style_emoticons/default/sunglasses.gif) |
