i got this table :
power vs SPL
1watt = 90dB (before cabin gain)
2 = 93
4 = 96
8 = 99
16 = 102
32 = 105
64 = 108
128 = 111
256 = 114
512 = 117
1024 = 120
2048 = 123
4096 = 126
now , if i got a 16W speaker , it can make 102db spl ...
my question is , at what frequency?
does this mean the spl is the same for all 20-20k freq range?

No the 90dB you have been quoted can either be a wideband white noise signal, or more likely, a really high point in the frequency range to give an exaggerated sensitivity figure.
Once you factor in that in the bass region you are on the roll-off curve it all goes down anyway.
Also the SPL at the bass end will depend on your specific box design and can vary hugely.
