Is this change in subwoofer worth it?

Question

i want to change a 10" 300rms 89 db subwoofer

for a boston acoustics 12" 300rms 92.3 db

same power same amp

will this make a nice sound difference

Answer 1

Some 10" speakers can realy crack but chances are you'll get a much deeper and louder bass with the 12" providing your rms power of your amp matches the 12"

Answer 2

The 12" seems to have a higher effiency rating so it will be easier  for your amp to drive.
