Ideas on your plan
. . . I have a Panasonic plasma 3d tv, 3d bd player, I play xbox, and have direct tv hd receiver.
. . . My room is the real issue. I have a 22'x18' living room with pergo wood laminate flooring and a false ceiling with 2'x2' tiles. The issue though is that this living room has large openings (say 3' and a 7' opening leading into the kitchen and dining on the left if you were facing the tv) and then another huge opening (14'), basically a continuation of the living room in the back if you facing the tv, that leads into a tile floor 20'x20' sun room with lots of windows and normal drywall painted ceiling.
An enviable situation, since you have a $3.5K budget excluding the TV, bd player and xbox you already own!
Your room's large size will drive your speaker selection.
- In general, a large room needs larger speakers and I 2nd the previous recommendation to consider two subs.
With that in mind, spend about 80% of the budget (i.e $2,800) on speakers and subs.
In your case, allocate
$1600 for a 5.1 set of speakers with 6" to 7" woofers (absolute minimum of 5.25").
- Look into strong value brands--PSB, Ascend, Infinity . . .
Leaving about $1200 for either two "strong-swimmer" subs (aka
SVS PB12-NSD or equivalent)
or one high end sub (aka
SVS PB12-PLUS or equivalent).
- Do not lock yourself into the mistake of limiting your sub search to the same company as the speakers--two different animals; a company great at building one does not imply it is great at building the other (very rare in fact!).
- For subs check out SVS, HSU, Velodyne, Epik . . .
Finally, you will have about $700 for a very capable AVR (Yamaha, Denon, or Marantz are my rec's, but also look into Pioneer models with Class D amps.
Concerning your specific ideas:
First option Kef 3005 system with marantz nr 1602 receiver. Cheapest and quickest (but will it give me any satisfaction of room filling sound?)
Complete waste of money, you will regret in short order--much too small and dinky of a speaker system for a room that large!
Second option Klipsch synergy f30 system with polk psw 505 sub, with Denon 891 receiver.
Klipsch speakers generally have high efficiency, try and test drive if at all possible--some do not care for the sound of the horn tweeters.
Stay away from Polk subs IMHO--can do way better, and your room will need it.
Third Kef q900 floors, q600c, q800ds, and q400 sub with marantz 6006 receiver.
See above on not limiting your sub search "to match" the speaker manufacturer.
I would like to make 7.1 surround but i'll just add that later.
7.1 is a bad idea unless you want to increase the budget--buying fewer, more capable speakers are what your large room needs.
Any modern AVR will support 7.1, and as you indicated, you can always add two more speakers down the road.
