Midbass

[Deto1992 5]

Is it possible to tune an amp so that an 8inch sub will act as a midbass driver? I have a kicker cvr 8 and a fosgate prime 250 and I was wondering if I could put the equipment to use and delay my purchase of midbass drivers until I have sufficient funds.

From the info you posted..yes or maybe even no.

More details.

Sure but it depends how the crossover section is on the amp. Does it have an adjustable low pass filter and subsonic filter? If so then you could use the two to create a bandpass set up where the speaker plays between a set frequency range. Btw all a SSF is a high pass crossover.

not just any 8" will have the desired effects. Should look for a midbass driver. Helps to post more goals/details of what you want to do

Depends on the frequency range you desire for midbass coverage.

The best midbass drivers I have heard are generally subs; however, there are a ton of subs that would suck serious ass at midbass.

[Deto1992 5]

yeah Im sure the CVR would. What is the general frequency range for midbass? The cvr specified range is 30-500 hertz.

[///M5 2,833]

Depends on the midrange you are using with it. Just because a driver is specified doesn't mean it will play nice. In general though Kicker is pretty good with their specs so it could be made to work. What/how are you going to cross it over?

Depends, is that in an enclosure? they need to be able to ran free air, unless your able to seal your door or make a box

[///M5 2,833]

And the weight of those will wreak some havoc on your doors

Theres only one way to learn and find out. Hook them up and see what you hear, would help if you had them in a sealed test box also. The sealed box will mimic the alignment you will have in a sealed door closest.

Midbass is a hard one to really put a set freq range on, especially in a car. I have my midbasses set at 20-630hz right now, but have ran them as narrow as 50-250hz.

So the point is, Its more about acoustic coupling to the other drivers in the car you are using them with, then just a set range.

I run my mid-bass from 60Hz up to 500Hz. When using subs it's finding how high they'll play and still sound good. Don't think that you'll be able to match this sub directly to a tweeter, you'll need some sort of mid-range.

Or a small full-range instead of a tweet if you can only do a 2 way.

Well right now I have the sub mounted in my rear dash. Figuratively, you could say that my trunk is the enclosure. I was planning on running it as a single midbass speaker out of the back dash. My mids are lacking a little bit and I thought that this could be a quick way to add a little depth.

[///M5 2,833]

Why not just cross your subs higher?

If your subs is in your rear deck, and it's free air, and you want to put a midbass driver in the rear deck, also free air.... that's a recipe for failure.

At this point, I am running an aq hdc3 12 out of my trunk. The cvr, which is the only driver in the rear deck, would be my source of midbass. The reason I started this thread in the first place was to see if I could use the cvr as a midbass driver to save money.

[///M5 2,833]

Lord I hope its not free air and is actually on a baffle. IB is typically a good way to run midbass.

haha yes it is on a baffle. It is not just bouncing around in the back of my car if thats what you mean lol.

Depending on the output of the sub, you could actually kill the midbass driver. I had a few customers with Crown Vic's that kept killing 6x9's in the rear deck because the sub would push them beyond their limits. I also think you wouldn't hear it so well without it being in some variety of enclosure.

alright thanks for the help man. Ill just wait until I can afford some midbass drivers.

[j-roadtatts 1,129]

Unless you are willing to turn your sub down to hear the midbass, don't bother.

[///M5 2,833]

Again what I don't understand is if they are in the same location why not just have your sub play the midbass as well? As long as it is capable it has more cone area than the 8 you are thinking of using and therefore will do a better job. Having midbass in the back really doesn't work for me at all, but if that stage killer doesn't bother you then there is no reason not to have the sub do the duty.

I do not believe that the hdc3 would play midbass frequencies with any glory. Also, to my knowledge, midbass frequencies exceed 250 hz which is the maximum LPF I can set on my amplifier. Does this mean that I would lose all frequencies above 250hz?
