  1. Voice Coil Ohm

    in Subwoofers / Enclosures

    Posted

    Okay so im just bored at home ( sick) so no school and i was wondering how i can find what my coils are really at for the ohm do i use a meter and put the pos in the pos part and neg in the neg part and set the meter to ohm or is there somthing else that needs to be done?

    This gives you the Re, or DC resistance of the coil. Because you put AC, not DC, voltage across the speaker in normal use, the AC resistance, or impedance is much more relevant.

    The impedance changes with the frequency so is not as simple to determine. The "ohms" listed in the specs for your speaker are derived from the graph of impedance vs frequency of the woofer.

  4. Best Sub/ Port placement and gen. box advice needed in 18" 4 door Ram Setup

    As long as the port length and internal volume are correct both of those boxes are both fine.

    The port area is found by multiplying the height be the width (72 in^2 for the first and 88 in^2 for the second)

    There will not be a noticeable difference between the two.

    I would recommend the top box configuration, as most people find that loading the port into the back of your vehicle and the sub facing up to be the best option.

  7. How Can You Tell Downloaded Songs Are Clipped

    I didnt know what section this topic can go under, but I made a soundtrack using 12 songs i downloaded from itunes, and 7 from Ares/PP (illegal sites lol) and he complained of clipping which is supposedly bad for your subs (literally on all the songs, most which came from itunes). Has anyone else had this problem and is there an alternative site for downloading songs.

    This sounds like your friend is turning up his stereo too loud. The iTunes songs are in high quality (256 kbps) so unless the producers allowed all of the songs you happened to download contain clipped bass (unlikely) the quality of the songs aren't the problem, your friend is.

    yes clipping is bad for subs because it sends a dc signal to the subs which heats them up fast. and use zshare lots of songs and its completely legal.

    Clipping does NOT send a DC voltage to your subs, a DC voltage is one that does not change over a long period of time. In fact, your sub will never even see the clipped wave due to the filtering properties of the coil. It will put more power into your sub and heat it up faster.

  14. Noobish Question

    There is no difference other than getting ohm loads

    A Fi btl dual 1 and dual 2 are the exact same sub just your able to drop the dual 1 to a lower ohm

    However your amp will run hotter on a lower Ohm load (because you are pumping more power through it) and you will have higher distortion from the amp.

    But from the subs point of view XXXX watts into 2 Ohms is the same as XXXX watts into 4 ohms.

    There would be a significant advantage to run your speakers of regular DC car audio amps.

    All amps use DC current, so your dj amps have a converter which takes the AC from your wall puts out a DC current for the amp.

    When you use those in your car you are converting the DC from the battery to AC through the invertors, then BACK to DC inside your amps through the converter.

    This results in a huge loss in power. If you are thinking of seriously making a permenant car setup i would recommend using car audio amps.
