Dumb Question

[CodyHendo]

So i had a friend as me this question earlier today and i couldn't really give him a definite answer. Im sure everyone (or at least someone) on this forum knows the answer. SO, "Why not have subs that are tuned for higher notes, and only have them play those, and then get subs for the real lower notes, and have them play the low notes?"

Im sure the answer is obvious and i am just not being able to think of it now, but i think he means having different box tunings, and different subs for different frequencies?

I brought up the fact that mainly people have the doors (mid bass) to keep up with the subs, but just wondering what the other reasons are.

You answered your own question. Subs play subsonic freqencies, then usually up to about 125 hz or so, depending on setup and user preference. Midbasses pick up starting at around 70hz range and cap out around 400, then midranges, then tweets, etc. So for higher frequencies you wouldn't have a subwoofer, you'd have a woofer.

If your friend's question is in regards to the 0-120 hz ( being generous, most guys in here like myself probably don't play their subs past 80hz) range. It would be more efficient and less costly to use one speaker to play the 0-125hz range, have a midbass driver pick up from 10hz or so below the max frequency from the sub stage, up to 400hz. So now you have two speakers covering just as much as if you'd use low sub/high sub/ midbass as you friend was suggesting. So it would be hard to justify that setup when it can be covered perfectly fine using sub/midbass combo.

In regards to multi-box tunings, I'm not a box expert but I would think that can potentially be a bad thing, hopefully someone chimes in.

Midwoofers/midbass are sufficient enough to cover 80hz and up to ~400hz, subwoofers are sufficient enough to cover 15hz-80hz, midranges do about 150hz-4khz, and tweeters 4khz to 20khz.

There is really no need in the average setup or even competition set up to have two substages, one 15-50, and other 50-100.

this is pretty much what i thought, just didn't know if there was an even larger idea as to why. but thank you very much for the feedback!
