Panel absorbers are usually pretty effective for room damping. Should be great with seven π cornerhorns and your room layout looks good for them too.
The four π loudspeaker sounds wonderful, and doesn't lose much to the seven π when properly setup. However, if you have a suitable room, the seven π cornerhorns do sound better. They generate sound with uniform spectral balance throughout the entire room and it isn't just the top end of the spectrum, it's nearly the whole audio spectrum. The blend between midhorn and bass bin smoothes floor bounce and the higher modal frequencies too. In your room, I would expect the seven π cornerhorn to sound very nice.
