[QUOTE="Charlie Zureki, post: 35192, member: 153"] Re: Is it a good deal? Macpherson M2X pairs in cases Hello, while using an Iphone, or Ipod MAY help show that the crossovers are operating properly, and that the drivers may not have any continuity problems.... the low signal will not rule out that the drivers have issues with over-extension, torn spiders, or even voltage threshold problems within the components of the crossover, etc... The real way to test a speaker cabinet is to actually put an amplified signal through them. Signal sweeps can help detect deficientcies in the crossover and with the individual drivers themselves. SO.... while you can do a simple test with an Iphone... it will only give you a simple answer....that the speaker cabinet's component(s) will reproduce a low amplitude signal....... it will not assure you that it can faithfully reproduce a high voltage amplified signal, or that the crossover is capable of operating properly within it's intended spec, or that, the purchase you intend on making is worth the money you"ll be paying. I'd also suggest that if you intend on purchasing and operating an Audio System for hire....that you be able to understand how to test, and trouble shoot the components of this system.
