10in under passenger seat?

yeah i used the first link to figure out that the sag on it is something like 6%.. not suitable for upward firing.  so the under the seat thing is a bad idea..

the whole thing about the rear deck isnt a bad idea, its a hatch back yes, but the rear panel is strong enough to support the weight (only 2kg) and i could always wire it nicely so that i could raise and lower the hatch.  but again.. thats an upward fire, and thats more trouble than under the seat, so i would go back to the under the seat idea.

and the trunk isnt a bad idea and no, i realize its not gonna take up a lot of trunk space but its also the fact that it is going to be a nuisance.  and i want to set it and forget it.  i dont wanna have to unplug it every time.  and ive got people in my car a lot so its gotta be permanent and out of the way.

physically its capable of going under the seat, u should see the beautiful gap.  i would have to take the seat out to do it, yes, but a big pain in the butt is ok to deal with.. if its something i gotta keep dealing with over and over.. thats not cool.  under the seat and out of the way.. thats awesome.  the whole under the seat thing would be perfect if only i could fire it upwards.

now my question is, is a 6% sag on a 10" sub really that big of an issue?

im putting the thing under the seat so remember sound quality isnt that big of an issue for me.  cause having the sub in there is gonna be a huge improvement over what ive got right now.  which is 4x 5.5" speakers.  they suck for low end.  want something to hum along with.  and this would be perfect if only it didnt sag so much.  so has any one ever just said.. "screw it.. i know it sags,.. but i want it there"??

i decided im going to go ahead and put the sub under the seat.  the idea is too perfect in my mind, and i think ive figured out a way to solve all my problems, thinking,.. out of the box.. so to speak.

basically the only problem i have with putting the sub under the seat is the sag.  the sub is fine under the seat and the box volume is shy but i can stuff it and it should come right up to where it should be.  so sag is the only issue.  ill think this over a little more when i pull the seat but i got two options.  sag can be minimized and even eliminated if u do one of two things, either change the orientation every so often (like an up firing sub would be rotated to downfiring every month or so) OR while the sub is on, it wont sag because its supposeted by the magentic fields, but while the sub is off, the sub sags.  what if i were to make a device that supposrts the weight of the magnet while its off?

hang in here for a minute.  the flipping option sucks cause its under the seat so i would have to remove the seat, then the sub,.. and filp the sub.  not only would i have to flip the sub but i would also have to take it completely out, cause by flipping the sub there would be no gap between it and the floor = bad.  flipping is out.

so if i can support the speaker fromt he magnet when its off,.. sag is eliminated.  i was thinking of some sort of panel that runs through a slot or something that i can manually slide from outside the box to slide under the sub when i turn the stereo off.  but theres an issue with making the box airtight in that case.  so i started thinking of even more slick ideas.

what about a solenoid that pushes up and mates with the speaker to keep it supported.  ofcourse this solemoid would only fire when the sub was turned off, and with a little creative electrical work that isnt too hard to do, i could even make it automatic when i take the key out of the ignition or what ever.  the only issue is that solenoids are magnetic. 

the question is.. how big is the magnetic field on a driver?  and would the device be thrown off by having a solenoid within 6 inches of the device?  if not 6 inches.. how far?  i would pull out my gauss meter,.. unfortunately,.. i dont have one.  i guess ill fire up the driver on the weekend and hold a compass near it. 

i would like to hear some feedback about this.  does any one see yet how i truely am insane?  i REALLY want to get that under my seat and im going to stop at NOTHING >: )

See how it sounds under the seat. If in the future you want to upgrade, Image dynamics makes some good subs that work in really small boxes. They would still sound better in the trunk though. You could build a really small box for them (like around .5 or so cf) and then just take it out when you need to move stuff.

yeah those two drivers are kinda like the sony im looking at cept for the sony has a responce around 30-2500 Hz, which is more or less what im looking for.  i dont want the bump.. i just want something that humz along.

still trying to think of a way to support the cone weight when its idle tho.  ive been thinking about the whole sliding something like a plate into place to hold it up but i wouldnt be able to hold a seal,.. atleast i cant think of any way to make something like that.  still trying to figure out the whole solenoid thing.

take it from these guys...they definately know what they're talking about...with subs you want to be the last person that the sound waves actually hit (aim the subs towards the hatchback away from you so that the sound'll bounce off of the hatch back and THEN hit you) ...and take advantage of the hatchback feature on your escort....
