My subwoofer install

I was so waiting for that reply!

Yeah, I was trying to not be too mean haha.


Free air actually takes far less power to get to the same output (compared to a sealed enclosure) because it doesn't have the air in the box holding it back. The air also increases control which decreases distortion which is why a sealed is better for higher power.

In other words, I'm not powering it a whole lot. The amp runs just under 400w, but I have the gain and boost fairly low.


Hey Luke, if you want to put a bid in to be the purchaser of these subs, I can send you all the samples you want :). Want me to give sales your email addy? If you can turn a few hundred a month for a few years, you can get them cheap!

[streetknight]

what amp are you running? that thing must take some power to push.

You tell 'em Chris...now send me a sample

Is it not obvious that I'm a speaker engineer? In either case, as I said in the post just before yours, if you look closely at the other terminal you'll see a jumper wire. This is because I rotated the lead wires from the voice coil so that a coil starts and ends at different terminals which allows me to wire the 2x2ohm in series.

It sounds better (higher SPL with less distortion) than my 12" in a sealed 1 cubic foot ever did. Probably due to the resonance of the speaker staying low since a sealed box raises it quite a bit.

I don't see any wire to the other coil ? if its there good if not set the tools down and get help.

Damn, you shocked Luke. Must be good shiz.

Oh..
Well I built the speaker, so what I did was change the voice coil lead wires so that a coil speads from one terminal to the next (rather than the each coil on its own terminal). This means the 2 ohm/coil is put in series with a simple jumper wire on the other side. If you look closely, you'll see the jumper.

I built it to fit the car cleanly as I knew how I wanted it from the beginning. I also did much of the design work on the sub as a whole, so I know a little about it.

Nice, dual voice coils too. Run some of that 10ga from the amp and send em to the other side of the sub. They don't put connectors on both sides of the sub in case you run out of wire...

[netcsk]

Not sure.. I'm sure other manufactures make something that looks similar, but this sub is not out there at the moment.

[matthew-mayhem]

that is sick, were do u find that in this market today

[netcsk]

Thanks for the compliments guys.

It doesn't have THAT big of a magnet. It's just a 30 mm thick ceramic magnet.

It's just a pretty sub with the cast aluminum frame.

Also, aftermarket Panasonic subs are limited (they aren't anything out of the ordinary either). This is OEM stuff to be honest. It's still in development but will probably wind up in a boat.


Oh, someone at DHL stole two of these subs while shipping them, so if you guys ever see any more of these, let me know :).

[silversleeper]

i dont ever recall seeing Panasonic subwoofers, for car audio installations at least. that shit is legit!

[StereoInstaller1]

WHAT
THE
FUCK
is that sub? BIG high power shit from Panasonic?

WOW.

Might have to become a dealer!
Luke

[ummagawd]

thats coool!

i've never seen a free-air sub with such a huge magnet... then again i've been long gone out of the car-audio scene
