    3 way with same mid drivers: pros/cons

    So im planning my next build for my doors in my 98 Dodge Ram.

    Here is what im thinking of doing, the shop i work at doesnt sell any "high end SQ speakers" such as ID, Seas, Focal, etc etc. So i will being going with two sets of the Alpine Type R 6 1/2" Components.
    Link

    My question is, what would the pros/cons be of using two of the same Type R mids in the door and one tweet in the pillar with the mids being crossed over at different frequencies. One mid for the "midbass" and one for the "midrange" then the tweet for the highs of course.

    I am aiming for SQ with this build.

    I called Alpine in attempt to get the T/S parameters, power handling etc etc. for each individual speaker since the specs online only give the whole setup specs which is 65-27,000 Hz and 110w RMS so that doesn't give me any idea on how low the tweet can play and how high the mids can go...... Calling them was useless to say the least, the only info they had was the info online, "65-27,000 Hz - 110rms" So i guess everything will be trial and error if i go through with this

    Any help is appreciated!

    Thanks,
    ~Jake

    Because i get them cheap through the shop i work at. And i know they are straight from Alpine, not an unauthorized internet dealer.

    Re: 3 way with same mid drivers: pros/cons

    very valid reason but imo you might wanna check out other products before going that route. You may get the stuff for cheap and know it's authentic but at the same time you could be missing out on lots of other worthy options.

    can you at least get these alpines?

    It's a waste. Get drivers made for what you're trying to do. The type R woofer can only play so high, and ideally you want the midrange to play your entire vocal range (roughly 200-5k). 4"ers seem to be the prime size that can extend high enough and provide enough oomf in the lower vocals(midbass will help a little as well).

    What crossover points do you have to work with? If you can fit an 8" midbass I think you'll be much happier with the dynamics vs a 6.5" midbass.

    Crossover points are unsure of right now, being that alpine's specs ****. But i can definately fit an 8" in there, im just not sure if i want to because it will bump me up into another SPL class

    I can also get Boston Acoustics products, if that makes any of a difference?

    Re: 3 way with same mid drivers: pros/cons

    ^replace the Dayton tweeter with a Morel Tweeter in that setup.
    Parts-Express.com:

    but the real trick would be isolating the midbass from the midrange.



    as to the original question, your idea is flawed. you need separation to play different frequencies, and you also need different drivers. you might as well install both Alpine mids and run them equally.



    have you been helped by me? i'd love to know. shoot me a PM.

    as far as other speaker brands - listen for yourself. make the decision that way.
