Friends/Edgar horn specialists help me out. I recently purchased a pair of Edgar 80Hz straight midbass horns. Overall, they sound very good but I'm getting huge peaks, over 10 db, at 80 - 100Hz in my room. Other freq. are flat. I measured in THREE different listening locations -- same problem. I cross them at 80 and 750Hz and measurements were done having the Edgar horns running only (so I know it's not the subs interfering with the sound). Is this a room issue or a characteristic of my Edgar horns? One thing I'd like to note, the horns are sitting on 24" high subs; my system is tuned to listen standing up.

Hi Bruce - look at Herman's installation - I missed his link - the midbass horns are sitting on top of H-baffles. Outdoors I found no ripple in the 100Hz horn - it behaved with ~3rd order slope below cutoff. Are the downward mouth horns more successful in the near field partly due to diffusion of beaming effects? Partly due to the wave hugging the floor boundary?
