Polk - Did I get it right?

post #1 of 18
Thread Starter 
I just ordered two Polk Audio RTiA5 for my fronts and two Polk Audio TC80i for the rears (I don't have any other option other than in-ceiling.)

I'm praying the Polk Audio TC80i's will sound ok.

For the center I went with the Polk Audio CSi A4. It's been mentioned to me that I should of got the CSi A6's instead to match the RTiA5s.

Do I really need to return the A4 for the A6 and will the TC80i's match the tone of the rest of the set-up?

I got a Onkyo TXSR706 to push all this and plan on ordering a HSU or SVS tomorrow for the sub.

In my opinion if you going to get a good sub (any svs-Hsu) the csi A4 with the crossover around 80hz will be good for the rti4, and I do not think that the tc80i are timbre match to the rti line but I would not worry very much, it is not that important as the 3 front speakers. In fact I believe that the only way to have a real timbre match is if all speakers are the same

Thanks for the reply. The TC80i's say they are voice matched to the RTi's, not sure if that's the same thing as a timber match.

Also, you mentioned the A4 center should be ok with the RTiA4's did you mean RTiA5s? Since it was the A5s I got. The CSi A4 center also says it's voice matched to the RTis.

I was just concerned becuase the RTi A5's have 6 1/2 woofers while the center CSi A4 has 5 1/4. It's the CSi A6 that has the 6 1/2.

I am hoping the A4 center will be enough since I'm already over budget and the A6 won't fit in my center channel enclosure.

I plan on ordering a HSU VT-2 or SVS 25-31 PCi today.

I'm not sure any speakers could technically be "timbre" matched unless they were all floating in mid air, since timbre refers to resonance which will be affected by whatever the speaker is sitting or mounted on as well as any reflections. You could easily match "timber" though by simply selecting all cherry wood.. :-)

I also have the Rti A5 mains, and originally bought the CSi A4... I exchanged it for CSi A6 last night as I felt a lack of impact on the center channel (for movies). Very pleased with my decision to step up.

Timbre matching and voice matching are indeed synonymous.

Timbre btw is the tonal quality of a sound, it's how we can differentiate a piano and a guitar when they are playing the same note and has nothing to do with resonances created by the location of the speaker.

Wow that sucks. I got it from Crutchfield so I can always return it. I guess I'll wait and see.

I don't mind the extra $150 so much as I do placement issues. My center opening is 7" and I believe the A6 is a tad taller.

I am waiting for my Samsung LN52A860 to show up. If the stand is high enough, I could just place the A6 in front of the TV. I really don't want to mount a shelf above the set.

Technically that's wrong..

From dictionary.com

Timbre: the characteristic quality of a sound, independent of pitch and loudness, from which its source or manner of production can be inferred. Timbre depends on the relative strengths of the components of different frequencies, which are determined by "resonance".

If you have one speaker sitting on a wood stand and the other on a glass stand they will sound different. The vibrations are going to carry onto whatever surface the speaker is on and change the color of the sound to some degree due to resonance thus changing the timbre. If one speaker is pointed towards a window and the other towards drywall they are going to sound different as well because the window will reflect the sound and the wall will absorb it. If one speaker has .100 or a millimeter difference in the thickness of wood or the density is a smidgeon off it will change the timbre. They would have to be absolutely identical in every aspect. That's why the term is usually used for instruments made of wood like violins (not for speakers) which will all have different timbre due to variances in the wood.

I suppose speakers could be timbre matched in a controlled sealed environment but not in your average living room. With that being said the only thing that really matters is what sounds good to the owners ears, the rest is just semantics

Either CSi will work, it comes down to how big your room is and much of a sub you buy.

If you look at Polks chart for determing which center to get you notice the center seems to depend on how big of a sub you get which to me relates to the size of the room.

I have a 4200cf room with RTi8s using an old CSi30 center which equates to the CSi4. I have a HSU VTF3-MK3 Turbo with 2 MBMs (one with each main) and found I needed the CSiA6 center but only margainly depending on what was playing.

If your room is smaller and based upon your sub choices I would think the smaller should work fine.

Indeed a speaker sitting on a glass stand and a wood stand will most likely sound different, however that's not a difference due to timbre, it's due to acoustical vibration. Same thing with room effects. The timbre, as you noted, comes directly from the source or the manner of production (in this case the speaker itself). Timbre is not so general of a term that it can be applied to just any resonance, vibration or reflection.

True..

However, IMO whatever the speaker is sitting on (if it changes the tonal color) becomes part of the speaker thus being part of the timbre. If the wood vibrates, causing the stand to vibrate, that will emit sounds as well changing the overall color even if it wasn't audible.. If you changed the woods on a speaker that would change the timbre just as if you changed whatever the speaker was sitting on.. That's why I don't believe you can actually have "timbre" matched speakers without a controlled environment and absolutely identical speakers with identical signals..

"Voicing" or voice matching (to me) would be a better way to describe matching up speakers but that's just my opinion

Thanks for the reply. My room is 20 x 14 with 12 ceilings and the back is wide open into a breakfast nook and kitchen. The left side of the room is open to a large foyer.

I plan on getting the SVS 25-31 PCi for the sub. Which from your post doesn't sound like it will compensate enough for the A4. The cheaper route would seem to be upgrading the SVS to the 20-39? I can't afford to go up to the Plus line.

My wife is severly disabled from a car accident and due to her brain injury, I can't go as loud as I would like most of the time.

Right now I have a entry level Polk center from 6 years ago. I don't even know the model. Got them from CC.

Yes, sorry I mean the RTiA5s

Also, even if the CSi A6's have 6.5 drivers = as the RTiA5's, you should consider that the size of the speaker box is different, that will mean that the bass response will not be the same( even the location of the speakers will change the bass response), this will affect the mid frequencies also, the only driver that is not affected by this is the tweeter, this is why the sub is so important, and this is the reason why the same crossover for all the speakers is recommended, so the bass will be reproduce from one speaker (subwoofer= driver=box=location). If you crossover too low or set the speakers to full range that’s when the size of the center speaker become more important. There are of course other factors like size of the room, but I think that if the RTiA5 works well in your room (by the way I think you made a good choice) the CSi4 should too.

I'm sorta having the same problem. I just purchased a pair of RTi A5's and I also have a CSi A4 with FXi A4's for surrounds - but I have no clue which sub to pick up. Sub illiterate I am . My room is 17 x 12 with an 8 foot ceiling. I was looking at SVS PB10-NSD, but I'm not quite sure...any recommendations?
I'm running them off an Onkyo 705 if that matters...Sorry to hijack!!

HIJACKER!!!!!

I'm in the same boat though, A5 mains, A6 center, FXiA4 soon, house, then subness
post #16 of 18
Might want to look into the ED A2-300 as well Tracy. I'm running that with my RTiA5's, CSiA4, RTi4's in a room that's 12 x 22 x 8. It's treating me well.
post #17 of 18
I've just ordered RTi A5 mains, RTi A1 surrounds and waiting for a good deal on the RTi A4s.
Don't think I can go A6 for the center as it's a bit too big for me. I listen 40% to music anyway.

About the sub, does anyone think getting a BIC H100 is skimping a bit?
I'm tight on space an can't go larger than a 15"x19" footprint.
Sorry, don't want to hijack a thread.

I wouldn't worry about it too much, availingfaith. Those big centers from Polk are nice to have if you have the space, but the difference is not always all that obvious to everyone in the same way. Remember that the center is mostly important to anchor dialogue on the screen for seating positions that are not always ideal. Otherwise, if the room layout is not too crazy (viewers sitting too far left or right of the screen, front speakers with poor placement ...), a phantom center (none, that is) can be a good solution.

I have tried different configurations with three different Polk Audio centers, varying from mid range to big monster, and I still think that the sound was quite excellent with the smallest version of the three (it was still a good center). As I said before, it's always nice to get the biggest center if you can, and congratulations are in order for those that do, they are impressive beasts to own, but it should not be considered a necessity IMHO, especially since modern surround sound AVRs can be very good at compensating and balancing things out when properly adjusted.
