Polk CSI a4 or a6?

Hi everyone. Im looking to upgrade my current Polk HT system: TSI 400, CS10 center, Polk sub and Denon x2500 receiver. The receiver is a recent upgrade and havent made any real adjustements. Im looking to buy the Polk RTi A7. Curious to hear people's thoughts on the center channel... a4 vs a6. I have the room for the a6. But, it seems big. my issue now is hearing dialogue when watching movies. Thanks.

Definitely the a6 - its dialogue is very clear, I had one myself.

If you're getting the RTiA7s, then the CSiA6 is the better choice. I have both center channel speakers. The A4 is also good, but the A6 will pair better with the A7s.

And yes, it is fairly sizeable, but it shouldn't be a problem if you have the room.

You can probably save some $$ if you can find a older CSi5 center.

A6 over A4, mismatched center over both.

Or, if you get either Polk center, make sure you have a good return policy just in case.

Let's just say that nobody buys Polk centers except Polk owners chasing the "timbre matching" unicorn.

As opposed to all the happy owners of for example, Chane A2.4 or Emotiva C1 or C2 deliberately bought for use with mismatched L/R speakers.

~ Are you a "geek hobbyist" obsessed with squeezing out that last 5-10% improvement? The economy will thank you...especially the Chinese one. Or are you more of a get-set-and-forget "casual user" who simply wants to increase your enjoyment of movies, TV and gaming? Relax, HT isn't rocket science, nor does it have to cost an arm and a leg---especially if you ignore the aforementioned vocal minority. And remember to smile...it's just a silly hobby, after all. :)

Im not dead set on the rti a7. I still need to go to best buy and listen to them. I currently have the Polk PSW10 10-Inch sub. Budget is under $1000 for 3.1 setup

With $1K you can get 3 much better bookshelf speakers with a decent sub, or at least as a second PSW10 if you're really happy with it.

Or even a great pair of towers that cost the same as good pair of bookshelf speakers: the Emotiva T-Zero ($400/pr) with C1 center ($200) then add an RSL Speedwoofer 10S ($400) ... I'd take that over the Polk RTiA7 + CSiA6 by a country mile.

I've spend a lot of time with the A6 center and it doesn't fair well at high volumes.
Dialogue gets muddy but at low/moderate volumes it was ok.
Depending on your listening habits it may/may not be an issue.

I would take up Zorba's suggestions

How high of a volume level are we talking about?

-5 to 0 MV
MLP roughly 6-7ft.
Although it did slightly improve once my friend added his Emotiva BasX 5175.
His old AVR-x2200w may of been running out of steam.

I personally don't listen that loud, at most -15 to-7 but often around -20.

Yeah, that's pretty loud. The relative MV on my Onkyo is generally -32db to -42dB, and I sit somewhere between 5-6 feet away.
