Hi!

My english is not perfect so sorry in advance.

I plan to buy a new home theater setup.

I'm on a budget and i'm kind of lost in all the specs and the matching between the amp and the speakers.

I already owned an amp: Yamaha RX-V681 https://usa.yamaha.com/products/audio_visual/av_receivers_amps/rx-v681_u/index.html

And two old front speaker from Sony SS-C421AV.

And for now I plan to buy those:

Centre - Pionner SP-C22

Surround - Pionner Sp-BS22-LR
https://www.pioneerelectronics.com/PUSA/Home/Speakers/Pioneer+Speakers/SP-BS22-LR

Subwoofer: Polk PSW505

Do the speaker specs are gonna make a good synergy with the amp?

Is this all wrong? (or not so bad)

Thanks!!
