I'm running Kappa 62.11I in my 17 RG fairing & was going to get 2 more to run in my lowers, just wondering if the 62IX are better or should I stay with 4 matched speakers? If I go with the 62IXs which place should I run them? TIA

 

I was wandering the same. Was about to order Infinity 62.11i and a CV B54 amp for my ultra. Talked to Crutchfield and they said they are basically same speaker, if I recall correctly, 62ix has a little more impedance.

 

If history repeats itself it will be better than the 62.11. Every 6.5 Kappa that Infinity has released has been better than its predecessor.
