Reflections and directivity - Onion - 03-Mar-2020
How omni-directional are the phantom golds? Is there any data or graphs?
I will be using them with BACCH4Mac which works better the less first reflections there are. I will be treating the floor, ceilings and side walls. I wonder if there are significant reflections from the wall behind the phantoms that would also need to be treated?

Although the following measurements are for a Phantom Reactor, they may be useful.

Thank you! Looks like there will be significant rear wall reflections as well - absorption all round then!

For the BACCH process a pair of Kii three or the D&D 8c may be a better choice due to the cardioid response these have. A pair of Phantoms may work well, it's a very good speaker, but you will really have to deal with reflections.

Side has heavy curtains, front has blinds which I thought helped but didn't. Ended up with absorbers at bottom of window which worked well. Not possible to treat 2 sides. With high ceilings, first reflection not a big problem. Floor has a rug, room has lots of soft furnishings.
Not the pergect setup, but satisfied with it. And I am using convolution room correction. See my setup.
Don't forget to properly position the Golds in the room like you would any speaker.
