Hi.
Have you listened to the Klipsh? And do you like them? And if you have listened to them, have you compared them to anything else, side by side? And what were they?
What's your budget for all speakers and subs?
What percentage HT to Audio do you expect?
Not gonna try to recommend speakers (including Klipsch) until I know a little more about your goals here.
The SR 7012 should be solid. I'm using a 6012, myself. If you decide to go Atmos, go .4 with top-front and top-back, like in either of these:
5.1.4
7.1.4
You will need to add an external amp to run all 11 channels if you go full 7.x.4. So plan on matching your Front-3 for voicing, then put them on a 3-channel amp (my personal preference... others will tell you to just run the L/R on an amp... your choice.)
That said, match your Front -3 as close as possible, but don't cheap out on the rest. You asked if you should buy smaller towers to match everything else up... not necessary... but do remember there is a lot of good detail that comes through the Surrounds, and (if you're a gamer, I find a lot of stuff happening in the rears). A rule of thumb I've seen is for Surrounds, Rears, and Atmos: don't go above 80Hz as the lowest freq. And if you are at all interested in 5.1 audio... you want those L/R Surround to be a little more full range if possible. (Oh, and if you are not a gamer, start 5.x.4... spend the extra money on subs, and you can wait to buy the rear channels and the amp you'll need for 11-channels overall.)
Now subs: I agree with Russdawg. Hsu, SVS, Rythmik, as well as Outlaw and Monoprice. All five companies have great product. Depending on your budget and usage, we can help you narrow down some options. I will say this, in a 2000'3 room like yours, you don't need to go crazy. If you check out the
Bassaholic guide, you'll see you have what they consider a medium room. I'm a fan of multiple subs, and with the 2 Outlaw X-13s in my room, I do not need more. These are potent, fierce beasts that I have turned down, now, to about 25% and still am fiddling with fine-tuning the gain.
If you go a little smaller, you will find a lot of great value in
Hsu VTF-2 mk2 (
currently on sale 509(+68s/h)each). Buy 2 now, and a third down the road.
Read more about multiple subs... you'll get it.
Also, SVS
PB2000 or
PC2000: probably great options for you too. And check out
Monolith 10" and 12" also.
Last note about subs. Depending on your budget... Do not skimp on good quality bass. Buy at least 1 of the best quality sub you can allow yourself to afford now, then save up to buy a second matching one later... and then maybe a third.
Hope this helps!
Happy hunting,
