Need timbre-matched front/center spkrs

badaudio

I have older RTFX bipole/dipole surround and PSW10 110W subwoofer Polk Audio spkrs. I would like to replace my existing front and center spkrs (other brands), but do not know what would match up. Can someone provide some guidance please? Budget is ~ $1000. Looks like the RTFX have tri-laminate tweeters, if this helps.

Receiver- Onkyo TX-SR602
blue-ray player- Panasonic dmp-bd35
TV- Toshiba dlp 56HM66
Room size- ~11'Wx33'L

Thanks
