Sound and Vision wrote this and I'm really confused...
Although the crossover is marked 120 Hz at the top of the dial, the system half power point (-3 dB) is 78 Hz. At the lower end of the dial, measured response extends from 25 to 60 Hz when the 80-Hz position is selected and 22 to 52 Hz when 40 Hz is selected. Interestingly, overall level is increased by 6 dB at the 80-Hz position, but there is no overall level change when 40 Hz is selected. As with nearly every subwoofer I've tested, adjustments to the crossover control will require rebalancing the subwoofer level as well.
Can someone better explain what they are refering to with the crossover?
Right now I have the crossover DISABLED on my PB-12 and I'm using my Pioneer 1014's 80HZ crossover setting. Am I doing the right thing there?
Bgillyjcu, these comments only apply to those using the sub's x-o -- very few of us. Almost all buyers will be using a dedicated sub out on a receiver or prepro and will be using the x-o in their electronics, with the sub x-o set to 'disabled'.
It is good that reviewers test the various controls on sub plate amps, as these are often not labled correctly or do not perform as one would expect. As more and more aspects of sub performance become dependent on the plate amp electronics, it is important to make sure quality does not slip in this area.
