bombout800 Posted August 1, 2009 Report Share Posted August 1, 2009 I need a quick rundown on what the difference between passive and active. Passive is being powered by the headunit???? and active is powered by a amplifier? Maybe i didn't hear right but i want to make sure!

Kasey Posted August 1, 2009 Report Share Posted August 1, 2009 iirc in a Active setup the crossover is between the HU and amp. in a passive setup the crossover is between the amp and speakers Quote "Audio is not a hobby it's a lifestyle" _____________________________Refs_1_Refs_2_____________________________ Link to comment Share on other sites More sharing options...
littleitaly1990 Posted August 1, 2009 Report Share Posted August 1, 2009 Also from what I understand, active is digital, like a processor, and passive is physical like capacitors... Quote A vitrolic, megalomaniacal sadistic psychopath. Link to comment Share on other sites More sharing options...
Nightshade Posted August 1, 2009 Report Share Posted August 1, 2009 iirc in a Active setup the crossover is between the HU and amp. in a passive setup the crossover is between the amp and speakers Kinda, but it's a little different than that. An active setup uses a digital crossover or head unit with a digital crossover to set the parameters for the speaker system. A passive is a built crossover with analog parts that work in the same type of way but are limited by what they can do. Active can be adjusted to the user's exact preferences and passive is prebuilt and determined by the crossover manufacturer. I may not be right on the money with my description either and I'm sure there is someone out there that can eloborate more, but for the most part it has to do with digital and analog. Here are some deffinitions for you that should sum it up: Passive Crossover: A crossover network dividing the frequencies without any active amplification or buffering components and which uses only resistors, capacitors and inductors. Active crossover: An electronic crossover which uses at least one active device for gain or buffering.

bombout800 Posted August 1, 2009 Author Report Share Posted August 1, 2009 so basically active would be running an amplifier and passive would be runnin of the headunit? sound about right? Quote 03 350Z Link to comment Share on other sites More sharing options...
Crump Posted August 2, 2009 Report Share Posted August 2, 2009 so basically active would be running an amplifier and passive would be runnin of the headunit? sound about right?

bombout800 Posted August 2, 2009 Author Report Share Posted August 2, 2009 ^^ this guy ha ha. I hope i don't see your ass asking for help. Wait im sure you know everything. You don't need help. This forum is here for this reason. I searched. Yes i did. Obviously i didn't find anything under the search results with your name on it. I forget YOU use GOOGLE!! "Ever heard of google"... ha ha your great. Thanks for the help man. You definitely wasted two minutes of your time quoting and responding to the post. Im sure google could use some customer service. Call them they may be hiring. You would be their number one candidate. Quote 03 350Z Link to comment Share on other sites More sharing options...
finkster Posted August 2, 2009 Report Share Posted August 2, 2009 (edited) one of the great things about running active is that the amp will only amplify the frequencies you need EDIT: and yest this question could have easily been searched.

Zade08 Posted August 2, 2009 Report Share Posted August 2, 2009 Examples: Active xover: Passive xover: I just remember that active you can adjust and control and passive is normal fixed to a certain cut off frequency.
