New Tech: Rear Window AS subwoofer

http://www.leftlanenews.com/magna-creates-rear-window-subwoofer.html

sounds interesting...but also sounds...i dunno...a little...dangerous?

 

yeah, that's what i'm thinking. when you blow your subs, that's one thing...when you blow THIS sub...not good. hahah. but i'd like to hear it in action! imagine a sub as big our glass (for those of us that have single piece glass)

 

I don't think it would be powerful enough to blow the seals or break the glass.
Ive seen a lot of power in the trunk and not break the glass. It looks like a good idea to get lows from a factory sound system without needing a bulky Sub mounted in the trunk.

 

my firm worked with bestop for a while, which is owned by magna, or at least was. magna develops a lot of cool practical stuff meant for OE or mass market auto use.

anyway, anyone remember "bass shakers" by (i believe) aura? they mounted under the seats of cars and vibrated according to the audio signal you fed them. they actually worked pretty well as a compliment. totally different concept than what was posted, but it reminded me of 'em.

 

Since the surface area of a rear window is many times that of a typical subwoofer, it wouldn't need to move at nearly the excursion of a typical subwoofer cone to move the same amount of air. This would hopefully keep the seals in place.

 

I'd be more interested in a power sliding rear window like the Tundra's have....

 

It will produce as much sound outside as inside... I see this as a big problem for noise pollution.

 

Something I also thought of as a con to this...have you ever rested your head against the back glass when riding in the middle? Man...this would probably dent your skull...haha.

 

That's pretty cool.

 

interesting...

 

I really doubt that it'll sound that great. I've seen some of the transducer exciter things before, and they're neat in principle, but execution isn't that great. I used to do custom home audio and theaters a few years ago. We had tons of jobs in the 6 figure plus range, and I saw some of these for bass that you coupled to a wall. They're good for visceral feedback "Bass shakers," but for sound production they're a bucket of meh. Bolt them to a couch though, and man, it adds to the experience.

Also, the frequency response and resonance of a glass panel is anything but linear. If you hit the resonant frequency there will be just a buzzzzzz, anything north or south of that in frequency will again, sound like a bucket of meh.
