LSiC used as Surround Speaker? I will give a good performance.

Bernal

Hello friends,
I carry my HT 5.1 to 7.1. However, by design and available space LSiC appropriate.
Taking my setup, the use of 2 LSiC as Surround speaker give a good performance.
Thoughts and comments.
Thanks to the Club.:)

"Call the LSiC selfish but most the sound in a surround system comes out of the center channel. That's why you need the best match. As the centerpiece of an LSi theater, LSiC matches all other LSi speakers for a seamless, spectacular sounding surround system. LSiC has dual Powerports for rich bass capacity, easy wall-mount ability with two keyhole slots in a compact size. Its advanced technology brings you crystal clear dialog and a solid music performance." http://www.polkaudio.com/homeaudio/lsi/index.php?s=lsic

Not ideal, but workable for rear surrounds. I would not try it for side surrounds.

I wouldn't.

Thanks for your answer:
The idea is based on the characteristics (LSiC and LSif/x) are equal.
Can you explain better why is not recommended.

Specification comparison
LSiC:
Overall Frequency Response 40Hz - 27kHz
Lower-3dB Limit 52Hz dB
Upper-3dB Limit 26kHz dB
Nominal Impedance 4 ohms
Recommended Amplifier Power 20 - 200 W / channel
Efficiency 88 dB
Crossover Driver 1: LPF at 200Hz, 12dB/oct.
Driver 2: LPF at 2.4kHz, 12dB/oct.
Tweeter: HPF at 2.4kHz, 18 dB / oct.

Thanks for your reply.
Check the following article:

It seems to indicate that is constant in the series

Those are more to do with baffle step/boundary effect.

Ok.
I also found this reference. I'm confused.

Polk Audio multi-driver speakers combat this with “Cascade Tapered Array” crossovers. One driver is “crossed over” at a lower frequency than the other driver, filtering out the frequencies where the interference will occur thereby eliminating interference effects). The Cascade Tapered Driver Arrays in Polk LSi C, LSi 9, LSi 15 and LSi 25 speakers results in clearer, more detailed sound and uniform tonal balance throughout the room. The sound is consistently accurate whether the listener is standing or sitting, in-line or off-axis. See more about Cascade Tapered Driver Array at www.polkaudio.com/catalog/technology/.

Between the LSiC and LSiFx - think of the difference in the speakers purpose.

The LSiC - Locks the sound to a particular place (typically your screen)

The LSiFx - provides a diffused sound field so the sound is more "over there somewhere" rather than "locked to a certain place"

Now think about your rear channels - Is the sound directed at them more for ambiance or do you want it locked to the wall behind you? Answer that question and it will help you make your choice.

I believe that the blocking effect in my room may be favorable.
I like "LSi 9" but I do not like his size for my room. Therefore LSIc thought.
If I choose "LSiC" which at best in my setup: as sourround Surround or Back Surround. I have the LSif/x as Surround.

McLoki

Have you thought about the LSi7? It is quite a bit smaller than the 9 when mounted on a wall?

Yes, I thought.
The "LSi7" I do not like.
I have to give up 7.1:(.

Bernal

Out of curiosity.
Has anyone tried to use two LSiC as Surround?
My supplier tells me, "may work well or putting too high or too low, to avoid reflections on the floor and ceiling"

lumpy

I use the lsi7's as surrounds and love them. much easier to drive as well.

I do not own the lsifx for side surrounds, but these appear for all practical purposes as dual lsi7's, so wouldn't the 7's make the perfect match as rear surrounds? (I'm no expert - just asking the question)

I find that rear sound is a distraction in everything except video games

Sounds like he has too many in stock and is trying to pass them off to you.

LSi7 not like.
Lsif / x is very different in sound to LSi7 and your work is excellent.
LSiC in its aesthetic design fits what I need. The doubt in his role as surround sound

I found that the LSiC's work fine for rear surrounds and I agree that they can be a good aesthetic choice.
I used them that way for some time.
I've tried almost every combination of LSi's including LSi97s, LSi9's, LSiFX's, LSiC's, and LSi15's.
In the end, I preferred using a pair of LSi15's.

Previously with the RTi's, I've also used the CSi3 center speakers for rear surrounds.
I agree that sometime speaker mounting or placement plays a role.

I found the room geometry and furniture etc. has a big impact on the sound.
In my more open main room, I preferred the LSi15's.
In my master bedroom I use the LSiFX's. The LSiFX has a bipole/dipole switch which allows you to create either a direct or more diffused surround effect.

The LSi7's and 9's ended up being used for separate 2 channel systems in different rooms. That's why I like banana plugs, because they let you easily try different speakers. I found having two separate LSi systems, plus some extra speakers, let me experiment with the setups and allowed me to set it up to what sounds best to my ear.

Thanks for your reply.
I'm a new approach. I was not so wrong.
You think that anger with my configuration?.

Hi,
Before giving up the Settings 7.1:(
Is there any other comments about the use of "LSiC" as surround sound.
Thanks club Polk.

McLoki

Give it a shot.

Get one in (buy used, borrow, or demo from a store), use it with your current LSiC center as a surround and see how it sounds. (just run with a phantom center while you are testing)

If you like it, buy another. If not, sell (or return) the one you purchased.

Easy eh - and let US know how it sounds...

Thanks Michael:
I'll talk to my provider.
I will try as you hear and do my report of result.:):):)

You should work a deal with your local supplier.

Since he seems to be recommending you try the LSiC, you should get him to agree for you to try this risk free in your HT room

If it doesn't sound good to you, then your supplier should agree to take the LSiCs back at no charge to you.

Or - if you do not have another supplier, you could also agree that if you buy the LSICs, and they don't work out, that you can return them for another type of speaker he does carry.

Sometimes, for surrounds, you can find speakers from a different manufacturer that provide a close match - it is recommended that you use the same brand but it is not a RULE.

woodsman10b

Seems to me that there are thousands of choices out there for rear surround, just for crossover reasons, why would you ever use a center for a surround? Makes no fricken sense to me...

It is an option that does not want to use.

Were you successful with obtaining a second LSiC from your supplier to try out?
My suggestion for your centers being used as rear surrounds is to mount them high and angle them down toward the listener. I found that you can use some rubber door stops or some styrofoam packing wedges to do the trick. Unequal rubber feet back and front can work as a more permanent solution. There are probably some specialty speaker mounts or wedges available costing 10-100X more that will also provide special sonic qualities that can be heard by special people.

Thanks for your advice.
I'll be reporting results.
