Fake plants behind speakers a good idea?

Silk works real works better, Infact plants in the room really help also.

If your system is really, really good (excellent), then use fake plants and you will be pleased with how the good sound actually makes them grow!

I have a 5' tall fake tree/plant in a back corner of my setup. I measured the room response with and without it. I found no difference in SPL's at any frequency. Also, it does't seem to effect imaging positively or negatively.

Live plants enjoy music; to set plastic ones behind the speakers is to waste the "psychic energy" which real plants could enjoy. However, it was found that in basement home theaters plants were not influenced positively by the music, and they died. This is why you never see plants in commercial theaters.

I have used the silk ficus trees back from the days of Martin Logan's - placed behind the speaker and it did help with diffraction and imaging. I have em, so they usually stay in the rear front corners behind the speakers. I have also seen this setup in many showrooms...

Have I A/B'ed with and without em ? nope.
