mz..if 20watts will never travel 100ft. and 500watts will.you say more
watts doesnt effect speed..hmmmmmm

You are correct.
Power does not effect speed. The speed of sound depends on several
factors but generally is about 332 meters/sec, power does not effect
speed, it does effect volume (SPL) produced when applied to a given
speaker/transducer. The greater the power the higher the SPL (Sound
Pressure Level).

SNIP

also guess your 100watts will be heard fine 1000ft away..since power
doesnt effect speed...

"Heard fine", relates to amplitude and frequency, not the speed of
sound.

Power does effect the distance and loudness at which it can be heard
depending on the sensitivity of your hearing. A completely deaf person
wouldn't hear it at all no matter the power. Does that mean the speed
of sound is Zero for the deaf person but something else for a hearing
person? I think not. How about an ultra sentive microphone and SPL
meter that can measure very low level sounds at 100 meters that *your
ears* cannot detect? Does that mean the speed of sound in air at sea
level is ZERO (against the laws of physics) because *you* can't hear it?
That's like covering your own eyes in a well lighted room full of people
and proclaiming "You can't see me", unless they are already blind.
Speed (meters/sec) and volume (SPL) and power (watts) are all different.
With a speaker of given specifications, power and volume do relate to
each other, speed does not.
