    Got a couple of fast question !

    1. Does 6 drivers @ 8ohm make a final load of 4ohm?

    2. What if 7 drivers @ 8ohm, what's the final load?

    3. Can I connect 6drivers or 7drivers on one http://www.partsexpress.com/pe/showd...number=260-144 , i want 5 or 6drivers respectively play 3000hz and below, the last driver play all the above

    4. How do I high pass the woofers crossed 3000hz and below?

    5. What good brand of home audio amplifier/receiver are the best bang for the buck that does around 150rms @4ohm, of course more is better but i find that they are all expensive, and don't know what is good in home audio, I need something that will control gain/volume/hpf and eq if possible and aux input for connecting to computer for around 250$ ...

    Re: Got a couple of fast question !

    Well, there is two ways of connecting drivers together: Series and Parallel- Series doubles the impedence and parallel halfs it for every driver added.

    **Edited due to apparent stupidity**

    To cross the mids off below 3000, youll need a crossover that cuts them off at 3000

    i dont know about the amp, shop around.

    Re: Got a couple of fast question !

    WTF are you trying to build? a line array?

    you can use 6 drivers, and make groups of three wired in parallel, then wire those groups in series to get ann 8 ohm load... i think.

    Then for the tweeters, use tweeters, mabye one, mabye more. then that crossover.

    1.)6 8ohm drivers in parallel is NOT 1ohm or 0.5ohm

    16 8ohm drivers is 0.5ohm

    6 ohm drivers is 1.33 ohm

    3.) Yes But wire to 5.33333 ohm

    4.) Passive Xover called a Capasitor to high pass, inductor to lowpass

    5.) cant help you there. High end Pioneer, Yamaha, etc....cant go wrong if you pay for it in most cases.

    Re: Got a couple of fast question !

    1. You want to use a 1" tweeter.
    2. You want to use one Aura 3" high passed at 3khz ?
    3. You want to use five Aura 3" low passed at 3khz ?

    If so, this is a strange recipe.

    Try;

    A. Connect all the 3" drivers to do the same job.

    or

    B. Use one 3" driver low pass ~ 3khz. Use the remainder of the 3" drivers low pass ~ 500hz for bass support.

    A or B depends on tweeter / 3" driver synergy. You have sensitivity issues to
    figure out.

    yes the 3" 's will all play 3000hz and below to 80hz
    tweeter =3000hz and up

    as for sensivity, i thought 6 3" would be enough to catch up to the tweeter ..it is not enough?

    Re: Got a couple of fast question !

    if I get 7 AURA and 1tweeter all in 8ohm, final load in SERIes, it would be 2ohm right?with box and all itll go around 3ohm?

    Re: Got a couple of fast question !

    Impedance rise is a little different beast for apps like this...not quite as easy for a subwoofer enclosure that only plays a narrow bandwidth.

    The only way you're going to find a receiver that does a real 150W @ 4ohms for that price is going to be something vintage, and it may be just an integrated amp...not that there's anything wrong with that at all Often times you'll find it's cheaper to build high efficiency speakers and use less power. Thy takes that approach one step further and mates insane amounts of power to the already-HE system

    Re: Got a couple of fast question !

    ya i realized
    i think imma pay for this amplifier
    http://www.partsexpress.com/pe/pshow...02-603&scqty=1
    looks like nice quality and will live more than 3years, plus its 2ohm stable..guess imma stick with that amplifier/receiver

    so wut about the setup im about to do?
    2x 7aura 3" and 1usher or any good tweeter 1"..
    all 8ohm so 2ohm final load..
    in sealed box
    will it sound good ?

    That's not a receiver, it's a power amplifier...so you can't select different sources, change the volume, adjust any tone controls, etc. Meant for if you have a preamp in front of it in the signal chain - not to mention that $400 for that kind of power really isn't all that impressive.

    Dang, I'm getting QSC amps for cheaper than that, and a hella lot more power too.
