6000 watt woofer! ;) |
|

For those with a overload of testosterone, here you go:

22" woofer. 6.5" voice coil. 900 oz magnet. 6000 w RMS.

Price about $7,500 for the driver.
Reading between the lines, it may be less than it seems for
SR.
Being a car audio product, its designed for a relatively
small enclosure for its 22" size - 4 to 8 cubic feet.
The "tuning frequency" is 32 Hz, so its -3 dB point in the
speced enclosures might be just below that, maybe 28 Hz.
It's probably not exactly a speaker for reproducing
earthquakes.
The implied efficiency is not high - might be less than 90
dB/W. That means that its 6 KW power rating relates to the
same acoustic output as a more typical 98 dB/W speaker being
driven by about 800 watts.
A hidden agenda is that cars have a built-in 12 dB per
octave acoustic bass boost starting around 100 Hz depending
on the size of the passenger compartment. Therefore, this
speaker probably going to sound thin in larger spaces, if
tuned as recommended. |

This also slows down the car.

Yes, and from what I understand, her driver compliance is very stiff
and the mass is excessive, so the movement is inefficient and the
frequency response is limited.

She helped the weather babe on one of the US football broadcasts (FOX) this
weekend, and her peaks were sharp and pronounced.

They are not woofers though, they are the upper mid devices known as
hooters. |

Do you think they were HORNy loaded?
They needed to be on a infinite baffle instead of
the dual phase plugs holding them in place.
There would be some definite midrange feedback if they
were in my face......

If you're impressed by fake drivers, that is. ;-) |

I expect this will seriously outperform it for SR.

It would be interesting to know what Xmax ( cone displaceemnt ) is for
that jack hammer
speaker though.

assume a bass beat which creates a steady demand for 6000W RMS, zero
conversion losses, a 100 AH 12V battery running at 13.8 V under charge by a
100 A alternator.
assume no other load on the electrical system.
how many minutes before the engine dies, the battery explodes, and/or the
alternator burns up?
i make it about 15 |

Funny you should say that.
There's this guy I know with ( fwiw ) a Corvette. It has a fairly stonking
audio sytem as standard. He recently told me that it flattened his battery even
though this was on a long motorway drive !

Now that looks like a pretty respectable subwoofer. An Xmax of 2.5". Not
bad! But they have little available in the way of specs, such as sensitivity
@1W. Even if it's only 91dB, that's close to 140dB at full power. That's the
kind of thing I would design if I had the manufacture capability. Price is a
bit extreme, but if you're going for no-compromise, I suppose this is the
current champ.
