Agreed but I feel the larger driver will deliver a smoother balance to mid range, even if it is small. Plus looking at the Alpair 11 MS design for wider desperation I feel this will also help. Don't get me wrong the FH mk3 is a great speaker, just being greedy and want a bit more 😉TerribleTanker,
The bigger driver in the FH-XL cabinet should give you the ability to play louder and provide more LF output; the mid-range performance will not necessarily be better.
