Bill,
Don't forget that you are still using a 16 ohm 2226. Therefore most likely you are still a few db shy of what the 8 ohm 2226 would give you. Also, i am using 14db attenuation on mine.I am ready to install my JBL E-130's reconed to 2225's which are slightly more efficient than the 2226, but mostly in the midrange area above 80hz. They might be around 98.4 db/watt per the LH forum gurus. The extra efficiency is due to the E-130 magnet structure which is more powerful than the stock 2225 magnetic structure.
I am looking forward to incorporating my JBL 2242 sub to take care of any "BASS" duties! This is one "Bad-ass" driver (18")and I have a 1000 watt plate amp with adjustable EQ. I figure to use it up to maybe 60hz to 80hz. Hmmmmm wonder why "pipe organ" music is coming to mind.......
