What op is asking has been done and has worked. You shouldn't have phase or cancellation issues as subs should be playing different. I'll try to dig up a design bit the box had a box with an 8 and a 12 poth ported but different cuts. These were all back a few years but the biggest issue was localization of the 8 playing 100 down to 50. This was also before dsp was cheap. The guy I saw had a car that didn't have space for larger midbass up front or doors.

I watched 87 episodes of Futurama over last winter break //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

its possible and plausible, just difficult and daunting. Its not really much different than having midbass drivers, but just more of a pita with 2 different sized subs instead of midbass drivers

Sound like I will look into a good set off component door speakers or something as I certainly would like to take the easier rout, I'm sure that will help solve the lack of high bass notes.

Thank you everyone for your help, I appreciate it! //content.invisioncic.com/y282845/emoticons/fro.gif.c695f1f814b01c4ad99fe7f8cccadd29.gif

I dont see it happening unless you got a miracle luck of the draw. or a dsp with -48 db butterworth slopes. By then its way better to just have a driver in a T line that can play 20hz to 80hz while your midbass takes care of 80hz and above.

this is your best option. deaden the doors while youre at it, itll help a ton with response. Also, you dont have to drop a grand on a good set of comps, check parts express out and see what they have to offer. Im looking at a set of hi-vi comps myself and have had several people on here give them a good bill of health. Theyre not Dynaudios or Boston Z's anything, but they look ok

Personally I've had very great success using smaller subs/larger midbass drivers along with large subs. Can a 15 reproduce midbass freqs? Yes. Can normal midbass drivers play into the sub freq region? Yes. Does this mean I want either of them to do so? Nope.

I prefer running large drivers with low FS and tuned low...I prefer the non-localized HT type rumble from my subs...for the high-bass/mid-bass I prefer a larger diameter mid-bass(ei Morel 9inch, Dayton 8, JL ZR8) or a really capable 6.5 inch driver (6w3, Alchemy 6.5's). I like to keep the 'heavy lifting' of the midbass off the shoulders of the midranges....so I'll cross the midranges somewhere around 120hz and I'll run the dedicated midbass from 60hz-150hz...sub from 60hz down...midrange 120hz up.

I've run Morel 9's with TC 3k 15's, Dayton 8's with Eclipse LMS 12's, and most recently 6w3's under the front seats along with a single Audiomobile MASS 12 (see build log link below)

Everyone has their preference...I like using potent midbass drivere/small subwoofers up front and crossing the sub really low.
