Hi All,

Just need a little advise for the experts on the forum.
I am interested in buying the following setup:

2 x Polk Audio LSi M 705 (Front)
1 x Polk Audio LSi M 706c (Centre)
2 x Polk Audio LSi M 703 OR Polk Audio LSi M 702 f/x (rear)
1 x Polk Audio DSW PRO 660wi (Sub)

Firstly, do I need to get the Sub as I have been told that the M705 have got sub in them.
Secondly for rear should I go with surround or bookshelf?

Lastly what Amp should I use. I am reluctant to use a separate amp for the M705 and the remaining speakers.

People using the DSW Sub, any idea if it can operate on 240V instead of 110V?

Thanks in advance.

Hello Malikaus!

First of all, it is false that the lsim705 have subs in them. Maybe the person who told you that has mistaken them for the LSI, which had powered side firing subwoofers built in.

Firstly, what the LSIM705 have is 2 cassini oval shaped woofers... They are woofers , not sub woofers, and while they seemingly have decent bass output, you'll need a subwoofer or two to hit the bottom octaves. Especially if you are a movie buff, you can't go without dedicated subs.

Secondly, that Polk sub is easily beatable for price/ratio quality. Polk audio subs aren't awful, but you can eaaaaaaasily maximize your bang for the buck on subs going somewhere else. I'd suggest some Internet direct subwoofer companies like SVS, Power sound audio, HSU research, Rythmik or Reaction Audio. The Polk sub you have chosen is not in the same league than the LSIM which are superb speakers.

Thirdly, if you have a powerful receiver, it should be ok. But a lot of LSIM users prefer to supply them with better power, and add a power amp to the mix. They are kind of hungry speakers, and not the most efficient at 88db/1m. Again, a power amp would be the ideal sitaution , while a powerful receiver is far from the worst case.

Fourth, it depends if your prefer directional surrounds versus "atmospherical" surrounds. The LISM703 will give you more focused, but more localizable effects, while the LSIM702 F/X will give you a better envelopping experience. Pick your poison. But keep in mind that the LSIM702s are OUTRAGEOUSLY overpriced. If you still want to go the surround FX way, you could get some Polk Audio FXI A4 AND another set of LSIM 703 ( making it 7.1 at least ) for the same price and obtain way more home cinema quality...

Hope it helped!

What receiver are you using?
What percentage of HT vs Music do you listen to?
How big is your room and is it open or a closed room?
Most people here will persuade you to go with a different sub I would think.

Don't buy a polk sub. find a internet sub company like HSU,rythmic,PSA,SVU that will deliver to you.
You will need a sub the 705 drop off after 40hz a good sub will get you to 10-20hz which you want for movies and 30hz for music.


the f/x will let you place them better for rears then the 703s.

Thanks a lot Laserjock.

So when you say add a power amp for the front speakers then what sort of Amp do you recommend??
For instance a Yamaha MX-A5000 would be OK for the entire 5.1 system?
The spec for the amp reads "150 watts per channel into 8 ohms (20-20,000 Hz) at 0.06% THD, with 2 channels drive".

Does it mean when all 5 speakers are running, the per/channel output goes below 150W? Would that be an issue with the M705 speakers??

I think after your comments, I'll go with M703 for rear.
Comparing the sound quality, do you believe M703 to be superior to the M702 F/X??

The reason I went with Polk sub was to ensure everything matches as it is coming from the same Supplier.

Due to lack of AV knowledge, I am not good at matching frequencies of the sub with the speakers etc.

On a separate note, how would you compare M705 to Klipsch RF82??

Cheers.

Thanks mate - The website suggests buying a Ultra series sub which is $1500+ where as I was looking for a cheaper model i.e. SB-1000/2000....

Malik : I'm currently owning LSIMs, and I've previously owned Klipsch References. IMHO ,realllly not in the same league at all .

But I'm no expert, I'll leave it on that. Just my opinion!

Thanks Aarghon. So which one do you prefer?
Which would be a better option for movies and games??

Cheers.

Well, I must say that for movies and games, the Klipsches are really impressive. They are a really dynamic speaker. Almost one movie theater out of two is equipped by Klipsch after all... Their horn technology is really great at shoving detail right in your face. I'd definitely give them a slight edge on the Polks for cinema.

For music, they really suffer towards the LSIM, though...Really suffer. Because of that, overall I really prefer the LSIM. But with that said, I've chosen them for a 80% music 20% movies application.

I'd say that if you don't do any critical music listening sessions, for extended periods ( the references are a really bright speaker and that can lead to fatigue...), the Klipsches could be what you really need. They cost almost half what the LSIM do, so if music listening isn't a pre requisite, they could fill your needs pretty well. And since they cost a lot less, you could put the saved money on a top tier subwoofer model

Thanks a lot.
I think I have to revisit my decision then as I'll be using the setup for movies mostly.
Any experience with Paradigm Studio 60 or 100?? Would they be good for movies??
