Just like the title, I would like to by-pass/disable the hi-pass crossover in order to chain two sb122s together. I feel that the crossover point is too high anyway. 160hz I think. I would like to run one side of the amp to them and the other to the tops. Thanks in advance for the help. |

Thanks Mike. I am confused however. On the back plate it is labeled in and out. In the manual it says you can connect from the power amp to the sub (sb122 a sub that's funny) then to the tops because it will pass only above 140hz or 160hz. |

Ah, now I see what you're asking. The NL4s are just in parallel: they pass the full range signal to the tops- there's no low highpass/lowcut when passing a signal through the Sb122. While the Sb122 isn't the best sub, I like mine - they add a decent amount of low end to my Zx1s, I can carry one in each hand, and they're pretty cheap. |

What are you finding confusing? The NL4 connectors are in parallel and pass the full range signal. The sub as a built in low pass filter. Very simple. Mac |

This is from the link. An integral low-pass filter allows the SB122 to be directly connected in parallel with a full-range speaker for truly impressive low-end output without the need for an additional amplifier and processor. The filter is transparent below 160Hz, allowing the SB122 to be used as an independent subwoofer in biamp applications without the need to disable the internal filter. For maximum output in biamp applications and protection of the full-range system when running in parallel, a 40Hz Hi-pass (subsonic) filter is recommended. |

Hey. I recently purchased a VRX918sp sub to go with my current system of two EV SB122's and two EV ZX1-90's. I'm wondering if I can disable the internal low pass filter in order to use the SB122's as mid range speakers. I would get an active crossover and send mid range signal to the SB122's, high range to the ZX1-90's, and low range to the VRX918. Would mid range just sound like garbage on the SB122's? And if not, any tips on removing the low pass or just in general would be much appreciated. Thanks! |
