Some questions about the the 150 (Oris Horns)

Hi George,

What efficiency should I expect (I'm currently using a 45 SET amp) and will the horns affect the size of the sweet spot?

Assuming you are referring to the Oris 150/250 then the efficiency will gain at least 6dB in the midrange and 12dB in the lower range. The tonal balance will change from just okay to full bodied without the honkyness...

The sweetspot will be more narrow but as a bonus extremely precise imaging.

I sit well back from the speakers (approx 4M) and the Oris will be even closer to the rear wall so I'm hoping that the distance will help the integration of the sound. The horns (center of driver) will be approximately 1M from the side walls.

Advised will be to use damping material on the side walls to dampen the first reflection in that situation...

Best Regards,
