The cs-27 in an AV receiver, with 7 amplified channels.
You need no other switching or amplification, only a source(s)and speakers connected.

I am using paradigm reference studio speakers. I have a ultracube 12 subwoofer. Should I buy another Supercube 12 which is only 1000 dollars or go for a sub 15 which is 3000.
Thanks

Go for the 2nd sub same as the first, by a mile.
The extra bass will be easier to place properly in the room, plus the extra low power will make life easier on the mains.
What speaker set did you buy man??
And you picked a good AVR, I think, should be fun!

Are they 60's or 100's as mains?
Some idea of the size might help.
I am unfamiliar with the mythos.

Do you have a paradigm center channel speaker? You should have. The deftech's are fine in the rears.

I am using mythos 10 so far looking to buy signature c5. but they are very expensive, may be end up with cc690.
Thanks for your time

That center channel swap will make more difference in the results than anything else, ranjogh, IMO.

Then run the autosetup function and enjoy!

Thanks Nuck.
But today I noticed a problem with my ultracube 12. There is a cracking sound comes from it. I checked it nothing wrong physically. Cracking sound comes when the woofer has to produce lot of bass. I think may be when it reaches its peak it produce cracking sound. Any Idea.

Only to turn it down, renjodh, either the sub lolume or input level. I would turn down the sub volume level and work the input to find the best balance.
That and a 2nd sub...a second point of bass output might negate the need for running so much power in 2 ways, one being that the room may have a bit of a bass null, and the 2nd unit may fill that from another location.

There is something for differing subs to avoid cancellation in the room, especially if said room is overly square.

For a budget of 1000$ or more and in a room of 4000ft/cubed or less, I'd be tempted by a PAIR of identical subs rather than a single, mondo unit. The gain from a pair and fewer problems with standing waves would make up for any advantages a single sub could muster.

Place them asymmetrically. Try stuff like corner for 1 and 1/3 down the long wall for the other. Don't place them both mid-wall or both in corners or ......well, you get the idea.

Nice, evening read.....
