How crazy is this? 8" mid bass in rear deck

[SS Teacher 177]

If the human ear is unable to detect the direction ot true mid bass (below 250 hz), why not run a single

8" woofer in the rear deck of my challenger to compliment the 6 1/2' component set up front and 12"

sub in the trunk? I bought a 5 channel Boston GTA amp super cheap and could car less about rear fill,

but would like better mid bass response. Please tell me why I'm crazy.

p.s.There is no way in hell my wife would ever let me chop up the doors to put a pair of 8"s there, and I am not running active.

I can locate bass from about 80hz and up, but that's just me but when it drops to to 50hz and under it feels all around me

I believe with midbass the time delay can be detected which is why u want midbass as wide as possible in your vehicle

Let impious chime in on this, he is the expert lol

You can localize WELL below 250Hz.

The real question is if you are okay with your midbass being from the rear why don't you just run your sub higher in frequency?

I haven't tried it yet, but if the mid bass on the rear shelf is complimentary to mid bass in the front (time aligned and at a lower volume) it could work.

It's allot more involved than that, but could be worth a try after some reading/research.

Do a search for " cone of confusion" and decide for yourself if it's worth your time and money.

I'm going to give it a try with my next vehicle.

It can be hard to blend well with your subs if you're a basshead and want a good front stage.

You can't locate midbass front-to-rear, but you can locate midbass laterally (side-to-side) based on interaural time differences. So a single midbass would be a terrible idea as the sound is still in stereo at those frequencies, which you would not be able to reproduce with a single rear mounted midbass, and it would significantly hinder stage width if you even attempted it.

There is an extremely long list of conditions upon which rear mounted midbass might work. But your plan doesn't meet any of them.

Keep in mind that placement is still very important, they have to be as wide as the primary midbass speakers otherwise stage width will be compromised. I.E. Placing them in the rear deck where rear speakers are normally located (which is typically directly behind the driver and passenger seats, if not a little more inward toward the center of the car) is still a very bad idea and stage width will decrease.

I understand this which is why I emphasized reading on the suggestion.

I should give this a try in my ranger due to the fact that the rear speaker locations are very close to the same distance form me, left side front to back/right side front to back.

I'm glad I didn't get hammered for my above post, as I haven't tested this to see, for myself, how well it can be implimented.

You can make it work if done properly. Back in 90's Richard Clark had an award winning sound quality vehicle that had 12" midbass drivers mounted in the rear quarter panels.

It is paramount that your installation is 100% free from rattles.

Question is, you do not want to go active yet you want to go to extremes with you mounting locations? Going to be impossible without proper processing.

Thank's for the input, it's really tough to read up on this stuff. 9 out of 10 search results are total crap or conflict with each other, I'm glad I found this sight.
