1000w subwoofer

Do not get hang up on the number. It means nothing. Because there is no norm how they came up with the number.
Its pretty much made up number.
Thats why it is such a nice round number.
But is it continuous watts? Peak watts? How long the peak?
Perhaps it can survive 1000 watts for a millisecond. But apply 100 watts sine wave, and it will burn.

There is only one way to find out how it will perform.
 
Which Amp, and which subwoofer driver?

A good way to judge the power handling of a woofer is to look at the voice coil size and compare it to a professional woofer from one of the big brands (BMS, B&C, FaitalPro etc.)
It's all about cooling 😉
And it is not true that there is no standard for power handling of speakers (and power amplifiers), e.g. FaitalPro specify power according to 2 Hours Test According to AES 2-1984 Rev. 2003 http://diy-audio.narod.ru/litr/AES2-1984-r2003.pdf
1000W in this condition is usually 4" voice coil.
300W would correspond to around 2.5"

Yes this is not totally scientific rule of thumb, but I think pro drivers will be closer to the truth, as the manufacture knows it will probably be driven to the max for long time 😉


Amps are usually also tested for hours at -12 db.


And then, will you drive the sub as hard as it would be in pro use?

Also one thing is the power handling, another is the physical limits, Xlim, which is dependent of the enclosure and whether it is vented or not.
