alright listen, if you know when a sub is at its limits ie thermally or mechanically, and you adjust accordingly, you will be fine.
only problem i see ''maybe'' is if the clues havent cured fully after a recone or something and you hammer on it while still wet.
you should be able to lean on it from the start without problems. personally, ill take a DD even though it says ''break in'' go full rich on it right away and have no problems.
people that dont know what to look for will be the ones to have problems
