After I plugged in an equalizer, dropped the mids and boosted the highs I could finally start hearing a little top end. I'll plan on equalization. Also, 120 should not happen very often.Reference is 85db at 40 feet so I should normally need about 105 at1 foot for most material. Only occasional transients should get up into the 120 range.

Thanks for all of the help. I'll report back after the trip to GPA.
