Onkyo HT-S9400 Questions (1 Viewer)

Hello all. I am new to the forum and have been reading through looking for suggestions. I found the following system at ac4l.com and had a few questions.
http://www.accessories4less.com/make-a-store/item/ONKHTS9400/Onkyo-HT-S9400-THX-7.1-Ch-Network-Home-Theater-Receiver/Speaker/1.html
1. Is this a pretty good system for the money? My room is about 20 x 20. I watch mostly sports and movies and like to listen to music.
2. Are there some aftermarket brackets I could use to mount these speakers in the wall? I would assume I could take the speakers out of the speaker box to mount to the studs in the wall and put a face plate over them?
3. I looked at the specs but did not see if this system could support a second zone. I have two speakers wired out to my pool. I think this can also support the app to control the receiver from Onkyo.
4. I think for $599 this appears to be a pretty good system. If anyone has another suggestion that may be better I am all ears as I know there are some very well versed folks on here.
5. Since this is a refurb, should I get the extended warranty?
Thanks for the help!
Eric

Hi Eric,
1. Yes. If you get an HTiB package, this is one of the better ones. It comes with a good receiver. The speakers should be decent.
2. You can probably find brackets. Check amazon or monoprice.com. Taking the drivers out is a very bad idea. The speaker is a system - the drivers, the crossovers, the bracing and materials inside, and the box all work together. Even mounting them on the wall as a unit is not a great idea, but it can work.
3. Yes, it supports 2 zones (it uses the amps for the rear channels).
4. That's a good price. If you can up your budget to $1000-1200 then you can do better.
5. I would not. I always use a credit card. Most cards will double the manufacture's warranty. Check with your card (and if they do not, time for a new card )
