    tuning to 28 hz

    if I were to tune my 12'' 187 to 28hz. and the only mid bass i have are the 6 1/2 infinity coxials. would i get enough mid bass or should i go with 33 hz?

    You shouldn't depend on your subs for midbass anyway...they should be playing subbass.

    I love my e12a.22 with a 27Hz ported enclosure. I would stick with the lower tuning.

    If you're concerned about not getting enough midbass, make sure you're sending your front stage as much unclipped power as you possibly can - if you're not externally amping those coaxials, get an amp for them!

    Let your subwoofer take care of everything under 80Hz or so.

    When you say bass hz do you mean the full range or how loud? Personally I like sealed. Thats just me.

    Re: tuning to 28 hz

    well would a sealed 12'' 187 get loud? and get low?

    it will b powered either at 4ohms with 400-425watts from a viper 1200.1

    or at about 7-800 watts with a viper 1200.1 at 1 ohm with the gains set low

    A sealed enclosure will always beat a bass reflex enclosure for extreme low end response.

    Just 'da way it is.

    However, you lose that nice overall 3dB output gain that you'd get ported.

    Yep, yep...My reason for asking him which he meant. Try sealed first, if you dont like the output make a lower tuned ported box.

    Re: tuning to 28 hz

    well i have it in a little under a cube sealed right now with 350 watts going to it. and i jus seems... blah... like cleaner than my old woofers but just really lacking in the way of loudness. the old woofers were getting 150 watts each in sealed encolsure. what would be an ideal wattage for the 187?

    True, however, as far as normal music a low tuned vented enclosure will seem to play a lot lower since it is more "bottom heavy" and the lower notes are brought out a lot more to compensate for the normal drop off of sensitivity to your ears. ex. in a 28 hz box you ahve to get down around 20hz before the sealed box is louder then the ported box......sub 20 hz is VERY hard to even hear, unless its at a rediculous level.

    IMO, if You have to ask, You won't notice the difference.

    In what low end? or loss of higher bass. It will definately gain a lot on the low end. Probably won't lose much from the higher bass.

    Re: tuning to 28 hz

    Well, in summary: the orig. poster is concerned about a tuning variance of 5hz. I'm willing to bet that once the enclosure is built it'll be atleast 1 full-cycle off intended tuning.
    I'm also going to say that the output of a generic 4th order ported will not be drastically changed for a 5 cycle variance, let alone the NFR, or 3db down point. Efficiency will not swing very far up the frequency band.
    Furthermore, tuning most ported subbass drivers below 40-45hz in a basic helmholtz will negate whatver midbass possibilities that the driver may have had. By the time the driver response rolls off, it'll be anywhere from 3-12 db down by 80hz. At that point, Your mid's should have well 'kicked in.'
    IMO, strong dedicated midbass drivers are a necessity in "good" reproduction in-car. However, I'm not a proponent of hpf'ing a sub driver nearly that high. Even high Q sealeds should be high passed at no more then the 60hz region.... assuming 12db/octave.

    Just my aural opinion. That's why I said, IMO above.

    SQ is subjective, output is tangible.

    -Nick
