  1. maybe not, but theres still other benefits that outweight passive crossovers. I have never seen anyone recommend going passive over active other than ease of wiring.

    And i also dont know anything a passive crossover can do better than active.

    You obviously didn't read the link I posted then!

  2. Ok, Im lookin Into painting my 03' EXT From Black to "WHITE DIAMOND"

    Is this Paint Expensive..?

    And what would you Estimated Thought of Cost would be..?

    And YES door jams And all...lol

    I painted my 91 civic with the one of the hardest colors - silver. I bought the paint from www.smartshoppersinc.com

    It's 220.00 shipped with everything you need and I mean everything (well you need an air compressor and gun)

    and I learned mostly from here www.autobody101.com . It did take alot of reading and then testing with my hvlp gun to dial it in for spraying the paint and then re-adjusting for the clear. If want to takle it yourself try small stuff like bikes or just small pieces of metal like 20" x 20" to practice on.

  3. Active means you can time align each driver separately. Which you can't do with passive unless you tri-amp but then you need just as many channels of amplification.

    Active is more efficient, and I believe it's +3db over passive.

    Not all electronic crossovers can do time alignment, as for passive's not being able to it's matter of placement, and +3db???

  4. In a passive network the components of the passive network bring the load to 4 or 8 or whatever depending on how it's designed. If you have two four ohm speakers (Tweet/Midrange) and you have a two way passive crossover for them, then depending on the components themselves (Value's of the components)would determine how much power each speaker gets but the load the amp would see would still be 4 or 8 or whatever you designed it for.

  5. one more thing. Running active allows you to tune everything to your specific needs (depending on the quality of the processor).

    also, having a passive crossover wastes energy. After all, wouldnt it be nice to amplify ONLY what you need?

    I beg to differ, Im designing my own passives for a threeway setup and it be controlled perfectly, and when you say waste energy exactly how much?

  6. Yes and it depends on what speakers your running and what range they are designed for and what range the amp can filter and at what decibel of filter i.e. 6db, 12db, these things matter.

    In other words you cant run a tweeter and woofer directly off the same channel there's no way to seperate them so a passive would be a good way to go but it would have to be one that was desgined to filter the frequency's according to what the speaker can play in.

  7. I read in "Advanced speaker designs" from radio shack, a book I bought years ago that performance was dependant on how the soft parts are balanced. If you had too much weight on the coil side it could bottom out and if too much on the surround, cap, and cone side it can come out of the magnet easier and have less control. A balanced speaker whether copper or aluminum would have great control if it's balanced weight wise.

  8. Yeah, I've seen that. It would be nice if our children could go to school to learn FACTS. This video is so full of half truths it isn't even funny. It is bad enough that our college system is overrun with liberal profs and their not so hidden agendas but now they are going after children.

    You said it, there's no such thing as both sides being presented anymore like there ever was but you know what I mean.
