infinity 6x9 +3 db switch

[severancej 0]

I have the discontinued infinity reference three way six by nines. There's a +3db switch on the tweeter housing, are they normally attenuated, or how does that work? i was thinking about turning the switch on, and i wasn't sure if it may cause any damage? I have them powered by a 2010 Rockford P400-4. Their nominal impedance is 2.67 ohms so i would think their getting decent power.

It'll make your tweeters brighter. Whether or not you need it, or like it, you'll have to try it out.

I think I turned mine on if I remember correctly, but I'm also running the stock HU.  I definitely helped out the tweeters.

Ok, i definitely like it. Just wondering also, if their normally attenuated and turning it on brings them to normal? Or is there actually a boost?

Flip the switch and listen.

No boost.  Only reduces attenuation from flat.

It's called +3db because it makes the response of the tweeter +3db over the mid.  But really it just reduces the amount of attenuation on the tweeter by 3db. It's not a boost.  With the switch set to zero the circuit is actually attenuating the tweeter by -3db.

 

That said, the amount of power delivered to the tweeter will still double compared to a setting of zero, so they will get louder faster and it will be possible to smoke the tweeters with a comparatively lower volume setting (assuming you are running enough power).
