I personally like speakers to roll off at around 60-70hz at -3db slope (??).
You mean -3db / octave 'slope' at 60-70hz OR roll off 3db at 60-70hz? I never saw that preference mentioned anywhere in your post. It would be easier for those who want to help if you made it clear, wouldn’t it? That’s not a hard/high goal to achieve. I believe you can find a pair of good speakers within your price range that also meet the high expectations I mentioned above. I wish you luck.
