If you like it loud you might look at some high efficiency speakers like Klipsch or Infinity. A 5db bump in sensitivity is like bumping that 65 watts up to 200+.

Some very high sensitivity types can gain you over 10db, or a 10x multiplication of output.

For instance a 65 watt amp into a 100 db speaker will be just like a 650 watt amp into a 90 db (typical) speaker....
