re: Home Theater - smaller 3 speaker systems

Funny thing is I just bought an entire setup like this after having the Bose Cinemate system as well. I eventually will go with a full 5.1 surround, but because of finances am starting with a 3 speaker setup.

Here's what I ordered:
Onkyo TX-NR636 - 7.2 channel, HDMI 2.0 and Dolby Atmos compatible
Klipsch RC-41ii Center speaker
Klipsch RB-42 bookshelf speakers

This will be my base and I'll add either floor standing speakers later or another set of speakers for my back channels.

I am planning on ordering the Infiniti Primus PS410 sub in the near future.

All in all I'm in about $800 for this setup thus far.

To answer your question, I bought a 7.2 system for the future to use multi-room functions later.
