I have a few questions (and I apologize in advance if they seem silly). I recently purchased a Yamaha RX-A3000 AVR and have been slowly purchasing speakers to add to it.
Right now I have the following Polk Audio Speakers:
1x Polk Audio CS2 Series II Center Channel Speaker
2x Polk Audio Monitor70 Series II Floorstanding Loudspeaker
2x Polk Audio TSi200 Bookshelf Speakers (the Monitor40s were out of stock at the time, and I believe these were their replacement)
2x Polk Audio PSW505 12-Inch Powered Subwoofer
The setup is pretty straightforward: the CS2 is in the center right beneath my wall mounted HDTV, the Monitor70s as the front left and right, the TSi200s as the surround left and right, and the PSW505s at the front-sides of the room.
I think the setup is fine and all works well? But I wanted to add some presence speakers to the mix (as I had some old Logitech Z-5500s lying around and going to waste - and they were pretty decent speakers for a PC, I thought that perhaps I could hook them up as front and back presence speakers?
I wanted to get some input on this and whether I would need to buy an additional amplifier (as the manual states) to power them for a full 11.2 configuration (from my current 5.2) or whether I could just leverage the amps inside the PSW505s? (as the Logitech speakers are small and I won't be playing my sound super loud either)
PS, I do not have Surround Back Speakers (as I am unsure at this point whether I want to bi-amp the front loudspeakers, it sounds fun and fancy, but after reading forums and posts - seems like it might not bring much to the table - perhaps you could comment on that too?)
Just to post some specs:
