mid speaker watts?
 
For tweeter PA-D44 Paudio spec sheet say 30W@ 1 khz, 50W@ 2 khz.

Can this be applied to midrange speakers?

The speaker Fs is 55hz and manufacturer claim that it is rated for 300 Watts.

If i use it in sealed box & Fs (with hp filter) as 150 hz, will the power handling change?

1) Post the midrange specs and model, otherwise it's a guessing game.
2) how will you drive it? (Active/passive).

Good you posted specs.
Otherwise I would have expected a 4" midrange with a 25mm VC and a small magnet.
Yes, given VC and motor size it may very well stand 300W RMS.

Thanks JMFahey,
I want to know something different.
If we increase the low end cutoff to 250hz, then can we use for more power? say 450W.

Yes, but given what you'll need for a 300W 250 Hz passive crossover, it pays to go one extra step and biamplify.
Use the 450W for your woofer and add a 100 to 200W for your midrange.
