Idea, dumb or good

Im still learnimg so trolls dont bother. if I'm understanding this right when your box is tuned low it don't do highs good and reverse for high tuned not doing lowes. What if you have two subs and two amps two boxes. One is tuned 25hz-40hz and amp set to block out anything over 40hz. While the other does highs bass hits tuned 40hz-100hz. They wont cancel eachother since they won't be playing together since the signal they are working on are different.

Not a good idea at all. Your subs arent supposed to play that high. Mine dont play over 60Hz. My mids play from 60Hz up to where my tweeters pick up. If you set things up properly you will be fine.

If you build your box properly and use WinISD you can find a flat response curve and still remain musical.

yea , what dragon said.

average crossover setting for subs is 80hz. i u have 2 set up you will have cansulation 4 sho....

Even when they are set to play at different hz they still cancel out?

You should read more. There will be a slight overlap unless your great at tuning. If you have to ask this question I doubt you know what slopes and rolloffs are.

I LPF at 100 cycles //content.invisioncic.com/y282845/emoticons/redface.gif.62fdbfe1a101588a808c4cff71bcb942.gif

You can do what you are asking but the rule of thumb would be to tune an octave apart IE 25&50hz.

If you want all you're cycles to respond as close to the same as possible don't use a ported box bro make a horn or a sealed. I roll with a Wicked One sounds awesome at every hz.

Well looks like my question was answered, thanks for the help I won't bother with it anymore

Your right about ports, and your concept would maybe work..Like the above guy mentioned maybe do 25hz-50hz, however it's generally better to have subs hit the lows well and have some beefy mid-bass speakers hit all the way down to say 80-40hz depending on the brand and what they can handle. Good 6.5-8" speakers will hit that low and sound good then your sub can handle anything below and from there just tune ur box to whatever you prefer, you can tune it low 30s or low 40s depending on what you want and have a really nice sound. I think the same way as you though If you really want your box to sound good at each cycle look into the Wicked One from Audiophile Tube Amplifiers and Loudspeakers by DECWARE

From the site:

This illustration is very conservative. By watching the impedance vs. frequency response of a ported box it is easy to understand why a properly sized and ported enclosure will offer increased power handling at the frequency of that port. But, the way this horn loaded design works is similar to having several ports working at several frequencies. We call it "a rubber throat" because the "port" if you will, or better spoken- "the mouth" of the horn changes in size and length depending on the frequencies it reproduces. I know this is hard to follow if you're not up on horn loaded enclosures so just remember the following:

A port resonates at a given frequency determined by the length and diameter of the port, while a horn resonates at a HI frequency and a LO frequency and EVERY frequency between the two. For this reason the woofer is dampened at every frequency between LO and HI. That's why it has such phenomenal accuracy, gain, and bandwidth.
