4" subwoofer? WHAT?
I was looking thru Parts Express, a place I used to buy speakers often at, when i came across this speaker line that they are now selling. A 4" to 5 1/4" subwoofer. Kinda neat really, allthough I suppose sales of these speakers will probably go more to the people making small bookshelf / PC multimedia setups, but I wonder what us car audio nuts could do with some of these speakers. Some of these 4 and 5 inch drivers have 3" voicecoils...INSANE!....of course, they arent cheap.

I have heard of one guy putting Fourty-eight 4" drivers in one aperoidic box (big sealed box) before, and hitting like 130 or so DB at like 30 hz (I read this in a really old car audio & electronics issue). SO, I wonder what a few of these drivers in a sealed box would do in my C4 hatchback. Hmmm, if I only had the time to do it.....(more like, if i had the money to blow)
Tang Bang is the company who makes the 4" subwoofers...They also make the 6x9 subwoofers that I and another fourm member were discussing....but some of their drivers look questionable.... Maybe some of these drivers would make killer c4 front bose speaker replacements?

The xmax on those speakers is 3mm. They move VERY little air. I think my headphones have more xmax... but seriously... Chances are, you wouldn't even hear them over road noise.
Your best bet would be JL W6 6" subwoofers... but for other than being different.. Just get a pair of 8's and be happy.
48 drivers? $1000 for 130db... That's like paying $50,000 for a honda civic. Keep it simple! I guess the unique factor is there, but in the end... Why? When it could have been done so much better for half the cost or less, with a single driver.

I wouldn't bother with those. 3mm Xmax and 4" of cone area won't be audible when the vehicles in motion. Plus, most of the tangband stuff has cheap paper/foam surrounds and even cheaper non-treated paper cones. I doubt that any of that would stand up real well in a vehicle. Just something to think about.

The Bose home systems use 2- 5" speakers in their bass enclosures. These systems then buzz the speakers at a frequency with which they operate most effectively, then, use porting the slow down the sound waves.
It's also why the Bose home subs won't dip much below 60hz.
I once listened to a B&O system... the speakers were tall (about 5') slim (6" round?) cylinders; shaped much like a pencil. The drivers were 2- 4" and 1- 1" tweeter.
The sound that came from those speakers was nothing short of amazing.
One of the 4" drivers provided midrange and vocals, the other 4" driver was ported down the tube to provide mid-bass. Impressive. Not so say that a nice sub would not have helped a lot, it would have, but as they sat, most impressive.

I never knew JL made a 6" W6. I know they make a 6" W0 though.
Yeah, a pair of 8W7s and a 1000 watts
, very happy

I agree with Kale...why mess with a bunch of 4's?

Oh, what about the Blose 901's? There are 9 drivers in each enclosure!

the system you speak of 6" round 5' tall sounds like either a tranmission line driver setup or a box built off the quarterwave theory
that is the resonant frequency of the speaker is produced using a carefully calculated method which the tube is built approximately 1/4 lenth or greater of the resonant frequency (it is basically one speaker soundwave {frontside}that plays and the backside sound wave arrive at the listeners ears at the same time effectively seeming to double the output of a speaker ) they work well with small speakers but are complicated to build and genarally require a lot of air space similiar to a folded horn or snailshell box design(almost the design bose uses in its wave radio only the tube types arent folded like bose)

I used to have the specs, I am pretty sure they are 4" drivers... and the bottom 2/3rds of the tube was the required porting.
It's been a while...
I understand what you are saying, and it makes all the sense in the world. It's really amazing what can be done with sound waves...
