XOver Setting for DB652 Speakers

dertitan2

I reached out to Polk Audio to ask at what crossover point should I set my amp for a pair of DB652 speakers that I will be installing on my motorcycle, they recommended 60hz, I just wanted to get a consensus from the folks on this forum, agree or disagree, anyone have any actual experience with these speakers and for this type of setting

60-80hz a safe bet.
