I never felt the need for a centre speaker.
You might (or really should) depending on the the of music you listen to. I’ve already undeniably pointed out (elsewhere on the forum in another thread) that the ability to reproduce lower than 30 Hz is a *requirement* in the case of Grateful Dead (90’s in particular) music. Also the case if you listen to classical where there are pipe organs involved.
The aforementioned said, I never felt the need for a "stand alone" center speaker, hence once reason I chose Golden Ear Triton Reference.
