Thanks guys , room placement has been a bit a nightmare, Its likely that the lumpy top end is the result of too many drivers all doing the same thing, for example I did one sweep with the umik that was much smoother above 4k whilst moving the drivers around. And though yeah, "nailed it" only to realise I had left the mic on the pool table. so the best spot for listening is 6 inches above the left side pocket. Its a little awkward to listen from there..
