B.S.

A speaker will "blow" (not the best word around) if it exceeds it's electrical or mechanical limitations either from excessive power causing thermal damage to the coil or an improperly designed enclosure which causes the mechanical structure of the speaker to break. Physical damage from mechanical failure can be a torn spider or a torn surround, the pole tearing away or even the cone breaking.

Any speaker can die an untimely death from misuse.

Feed that speaker 4500 watts RMS @ 1 ohm and see how long it lasts.
Connect the speaker to a wall outlet of 120VAC @ 60HZ and see how long it lasts. I know of subwoofers that can withstand being plugged in all day long making a very loud 60Hz tone. LOL ... There are, however, very few subwoofers that can take that type of power.


Ask this guy for the actual technical specifications, not some mumbo jumbo.
These will tell what the speaker is actually capable of.
If he can not provide this data, then he can not prove his product can do what he says.

he was only talking about at 4 ohms it could handle about 1500-1750 peak and roughly 800 rms. Lol It took me all weekend to beat that info out of him.

oz I know that any speaker handling 4500watts @1 ohm would practically through the magnent and coil through the roof.

Only 800 RMS?

...and he said you can't blow the sub. LOL

I know of a 10" sub that is capable of taking 7,000 watts RMS.

I had made that into a chart with spaces, but when I posted, the spaces went away so I used _ to seperate everything. LOL
