tiny amplifier.. big speaker?

[weltersys]

More likely melt your speakers. Or set them on fire. I don't know any speaker that is rated to handle 40 KW. Anyone have an example?

The Matterhorn is a 40-driver, 40 kW self-powered Tom Danley designed single tapped horn subwoofer which can produce 105 dB of output at 250 meters, with a response -3 dB at 12 Hz.
That is about 153 dB at one meter, 123 at 31 meters (100 feet).

I figured that one would come up. That Tom Danley is a nut. 😛
(you should be able to put together a 40 box line array that can handle 40KW, if you have enough room)

Omg nothing found for matterhorn links broken!

And I would buy this if It didn't weigh so much and didn't cost so much money!

I googled matterhorn woofer and found this video - I've seen it before, probably from a link here on diyaudio:
The Matterhorn - Worlds Largest Subwoofer - YouTube

 

[realflow100]

i've seen that plenty of times lol
I am thinking of just going to walmart spend 90 dollars and get a great subwoofer like pioneer
At least something other than DUAL
who knows how good it will sound compared to dual? doesn't hurt to try does it?

I'm sure you could do better with the $90 from parts express.

See if this link works. I clicked subwoofers, then filtered the results to under $100. Plentyyyy of stuff to choose from.

praveenkumarpklg, there are many threads here that will teach you that. You have to search and read. It may be better for you to start your own thread.

Check out the JBL GTO1214, too - nicely built, cast frame, and will stand lots of power.

Similar sort of money to the Infinity.

This thread, or a least the first post, is a great illustration of how poorly most people understand speakers. Realflow has good company on this one, the vast majority of the general population! 🙂

Speakers aren't light bulbs, and they aren't motorcars. They just don't work the same way and are not rated or specified in the same way. Maybe the forum needs a FAQ explaining this.

I know one guy who thought that audio was DC. 🙄

I told him different.

"no 1 watt is not extremely loud. "

There must be a language problem here, many of the speakers mentioned here are 100dB/W and higher, and you don't think that is loud?

That's loud in my book.

that is theory, only real speakers in real environments counts. I have tried a lot in my time including PA. A fullrange system will never be extremely loud, and will never (never say never I know, but almost never) exceed 95-98 dB sensitivity. And especially in PA you have a wider dynamic range, that the amplifier need to support. So a 1 watt RMS amplifier will never be extremely loud.
