I used this as a replacement center speaker. The sound is definitely better, it is clearer and speech is a lot better to understand. I am very happy with this purchase.
I used center channel for watching blurays and its dialog is very good when paired with 12yr old Harman receiver. But pairing it wit 2yr old Denon 4k receiver didn't match well. This one replaces my Sony CS center as it is a notch better since it puts out more audio output at the same volume level on my Harman. For twice the price at $200 last sale, Its a keeper since my bonus room needed this power. But that Sony one is also very good, I moved it to my smaller room.
Bought this speaker on sale to replace a cheaper center channel speaker I bought a few years ago. Great sound, made a noticeable difference. Very happy with this purchase.
