[QUOTE="Immacomputer, post: 6454939, member: 570419"] Your view of impedance rise is like many others who think that it will kill the performance and high rise equals low output. This is not true at all as these spots of high impedance are the resonant points of the system (the points of greatest efficiency). That is why a sealed box can have a flat response even with an impedance rise of more than 30ohms at certain frequencies and be back to 4 for others. And if you want to make an enclosure with a very flat impedance curve, you have to build a correctly designed and tuned transmission line. Done correctly, they have very flat impedance curves but that doesn't mean that they're loud. It had much better benefits than that. [/QUOTE]
