I have the Polk Monitor 70 Series IIs front, 50s rear, CS20 center, svs-PC13-Ultra sub and Onkyo TX - NR609 receiver (100 watts per channel). Would this center be a big step-up from my CS20? Would it blend well with the fronts and rear? Also would I need to get a new receiver to drive this center?
I had the same setup, Monitor 70s series II and CS20. For $200 I bit on this a couple weeks back. It's a noticable improvement and the speaker itself is extremely well made. I still am using the Monitor 70s and soundstage sounds great to me. Using an Onkyo with 90w per channel and sounds great to me when pushed.

If I was getting the LsiM towers and all that then maybe invest in more power. For the center and some Monitor 70s? It sings just fine with a modest receiver. I don't think you'll regret it, I sure don't.

I currently have the def tech pro 1000 l/r/c. I feel like the vocals are a little muddy in movies. Is the Polk an improvement? If probably pair with the lsim bookshelf when they go on sale again.

I've ordered from Adorama but wasn't sure on return shipping costs. Was sure if it's worth taking a chance and returning later.
Thanks
Low end Polks can be muddy. I picked up a Polk Signature S35 because a customer needed a slim center channel and it was very bright and clear, so ymmv on this model.

I just ordered this $200 center channel to connect to my 2009-era Sony 5.1 theater-in-a-box that I spent $100 used on Craigslist in 2014.

Feels like this is the start something dangerous.

any good set-up with this speaker if I want to build a 5.1 home theater below $1000?? I was planning to just buy a Htib which cost $400.

I have deftech pro 1000s as well. A common problem with there smaller speakers is that they misrepresent the ideal crossover frequency in the marketing, and DAC will often detect the wrong setting because of the low frequency bump. The tested -3db point for these is really 150hz, with further dip until about 80hz. In room is slightly better. I love the upper mids and highs on them though.

One option is to combine with a subwoofer, set the crossover to around 150hz , and it clears up a lot of the muddiness (though it really should probably be at 160 or even 170). This is nearly double what it ideally should be. This can clear up the speaker issue. However, now your subwoofer is doing much more work than it should and processing directional audio range. This is not ideal and could cause other complaints depending on your setup.

What does this mean in English? Replace them with something that has a better frequency response and put these as surround speakers instead. If small size is the requirement here, check out someone like NHT that has a much better size/price/performance balance. If size is less important, moving up to a larger cones with something like these Polks can help as well.

Good luck!

Rather than a HTIB, I'd suggest just buying a $200-$300 receiver + something like Sony Cores when on sale for $75-$100. If you want to splurge and stay in the Polk family, then S15s at $150ish.

So $200 for this center + 300 AVR + $150 (or $75) for Cores or S15s. Go cheap w/ surrounds if need be (Daytons), then add $300 sub. Around 1K total.

Maybe consider something like this sub:

I have a 2009 era Sony 5.1 too (HD-275). Let me know how this goes. If you like it. I have been trying to find a reason to bite on these....

If I have T50s as my left and right speakers would the difference in quality make it so I shouldn't buy this? I'm so tempted.
The highs may sound "weird" as mixing a ring radiator tweeter with silk dome tweeters in the t50s. For basic TV, you may not notice, but for panning surround sound in movies, etc, it may sound a little weird.

I realize this is a somewhat vague answer, but there is a clear mechanical difference in the highs that you may or may not notice.

Basically, this can be really subjective to the listener and the listening content.

I have noticed it. I'm just curious if I should bother with the YPAO or not

If you changed any speakers, you should ideally recalibrate the receiver with YPAO. Then, give your ears a few days to adjust.

That being said, I don't think it will make much difference for the balanced corrections for mismatched highs. It just isnt designed to do this sort of thing.

If you already own it, it cant hurt to run it in case your ears are really picking up some other simpler inbalance.

Good luck.

Will this pair well with my Rti A3 fronts?
Or should I go for the CSI a4 or CSI A6 instead?

I have the Polk Monitor 70 Series IIs front, 50s rear, CS20 center, svs-PC13-Ultra sub and Onkyo TX - NR609 receiver (100 watts per channel). Would this center be a big step-up from my CS20? Would it blend well with the fronts and rear? Also would I need to get a new receiver to drive this center?
TL;DR: easily a big step up in quality and sound presentation going from a CS20 (mirror model of my CS2 I replaced) to the 704c/706c. You would get away with using your current receiver for now if you're ultimately going to just replace your center speaker. However, an external amp is going to bring out the best qualities in the LSiM line if you plan to expand and you might after hearing the upgrade going from the CS20 to the 704c/706c. I believe you would get a bigger step up in sound quality going to an external amp on your Monitor line speakers than upgrading them right now outside of the center channel upgrade. The CS2/CS20 was one of Polk's worst center channels in recent times.

Note: I run a Marantz 8012 and my front sound stage is driven off an Emotiva XPA3 Gen 3 amp.

I upgraded my old fronts (Monitor 70s and CS2) to LSiM 707s and the 706c respectively and I was most blown away by the upgrade in the center channel. The CS2 is muddy and has a lot of grain in its presentation. It doesn't image well off axis at all, either. However, I just lived with it but I wish I hadn't for so long. Upgrading to the 706c has been a game changer - Dialogue is neutral, separated, and clear.

Now I know this isnt a deal for the 706c, but I will say that the 704c would be a better match for the Monitor 70s. The 706c throws a bigger soundstage than the CS2, and even though I level matched them to the 70s, you could easily tell the 706c was the better speaker. It was like the center was over powering the 70s but it was just the difference in presentation quality.

Tonally though, I felt the 706c timbre matched my 70s better than the CS2. The whole LSiM like still retains the "Polk sound". Backing down the level on the center helped, but it made me cave and order the 707s immediately as the front stage never quite sounded balanced after just replacing my CS2 with the 706c.

If I was balling on a budget, I would recommend upgrading to the 704c as I am sure it will blend much better with the 70s and not over shadow their sound quality so apparently.

And that's not to say that the 70s are bad speakers. They're tremendous bang for the buck. So while I was impressed immediately with the upgrade in the center channel and could easily hear the tremendous step up in sound quality, I didn't get quite the same impression going from the 70s to the 707s. But that's a different comment for a different time.

Thanks for coming to my TED Talk.

I ran a 706c with Monitor 70s for a while and it timbre matched better than the CS2 it replaced with a silk dome tweeter. I have found owning many tiers of Polk Speakers over the years that they are still voiced very similarly and you can get away mixing between product lines.

I presume this is better than the Polk Signature S30 I was about to buy. However, if I get this will it be properly "matched" with the S20 L & R bookshelf speakers I plan to get?

Thanks!

EDIT - I see the 704c has been around $200 on Amazon for a while now.
