So from what I've read, speakers with higher sensitivity ratings will get louder quicker than speakers with a lower sensitivity rating.


I've also read that it really only makes a difference if the sensitivity ratings are significantly different. Is 5 db (93 vs 88) enough to be considered significant?


I have a set of 602s and BT 6.5s with a BT 2180 for my 16 RGS waiting for it to get back from paint. I rarely ride 2 up and throw the tour pak on about 30% of the time just for extra room because my better half likes to buy crap. My thought is put the 602s in the front (similar SQ with better bass and louder overall) and have the BT 6.5 in the tour pak pods (not doing lower fairings).


Here's the real question: If I'm thinking about this correctly, will the BT 6.5s get louder fast enough to seem a little louder from the back because of the higher sensitivity until I get to really higher volumes and the 602s take over, or am I just overthinking this and it won't really matter?

 

I would never run those two speakers in parallel. You're assumptions are correct, 5db is quite a bit. You want to run the same or very similar speakers in parallel for that very reason. Will it work....yes. But not the best way of doing it.
