Mixing sealed and vented enclosures

[ohthexcitement 10+ year member]

Different enclosures means different transfer functions. Different transfer functions means different frequency response, different phase response, different group delays, and difference in tonality. All those differences can lead to a degradation of sound quality. It will probably still have decent output but will not be as capable as having all the subs in the same enclosure specs to keep the transfer functions as close to each other as possible.
If your ported setups don't handle themselves at high volumes, lower the tuning frequency and lower the enclosure volume. That should help give the subs more composure at higher volume levels.

And that, folks, is a hot bowl of positive. Thank you much for the education.

Thank you to you others as well for your time and efforts. I have more testing to do.

I wasnt trying to dissuade you in any certain terms. There is always a learning curve when trying something new and this just happens to be a part many have gone through before.

The reason I was trying to avoid all the physics behind it, is that no matter what something looks on paper, the only way to know for sure is to try it. And like many things in science its not just black and white.

That is why I was saying that if you are curious you should try it out for yourself and see what the results are because they may differ for you than someone else.

You never know for sure and you may in fact like what you come up with.

I fully understand your point. I was just refering to the physics behind why it "wouldn't work" as some said, not how it could work on paper. I am a mechanical engineer, and sadly, could not answer this for myself (I lost a bit of knowlege over the years I guess). I was born into a situation where trial and error was all that I had, then ended up going to school to fix that. There are cases where equasions predict a different outcome than what actually ends up happening. However, the vast majority of physical questions out there can be, at the very least, ball-parked, and running a numbers is free (pending the knowlege of how, of course), whereas trial and error is not. Take into account all equatable variables, and you can get surprizingly close to reality //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And thats the biggest problem //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

There are so many variables when dealing with sound in a vehicle that it is nearly impossible to model with any certainty. Also your brain processes sound much differently than it looks on paper.

Cost is definitely a limiting factor for trail and error and so is time. Comprises usually must be made.

I understand the quest for what I term as sonic nirvana and have yet to perfect it. Not to mention my idea of this will most likely differ from yours. This is why I say you kinda have to just see what works for you since only you can decide when to call it quits.
