Yes there is a TV hooked up with the receiver and I am curious why you ask.

I was wondering if you have an AV receiver because you have more than 2 speakers for movie and TV surround sound.

Better speakers are about better sound quailty, better frequency response, details, imaging and sound stage at any low or medium or higher volumes, not necessarily about playing louder.

If you do ever upgrade:

4" Micca RB42 have a matching center if you like Micca.

5.25" Neumi BS5 have a matching center.

5.25" Monolith have a a matching center.

5x Jamo on sale for under $170 in black or white with 5.25" pair plus 4" pair plus matching center.
