Thinking about adding LSi9 Speakers

jgladden

I purchased the LSi9 front speakers, switched my Yamaha RX-V2200 to 4 ohm load and balanced all the other speakers. Sure enough on this the second night of listening to movies and CD's the reciever shut down while in 6 channel stereo at a very modest volume level. Salesmen at two places assured me that this has not been a problem for their customers. I know who to listen to from now on. Many of you seem to like the RTi series. I am looking for highs and the LSi has them in spades. Will I get them with the RTi6? I would like to stay with a bookshelf speaker. If I get an Adcom amp to run the LSi9's from the receiver's output RCA jacks can I set my Yamaha back to 8 ohm mode? Before the shut-down I had to lower the level of my front and rear center and rears so they didn't play louder than the LSi9's. My System: Yamaha RX-V2200, PSW 404 sub, CSi30 center, FXi30 Rears, RM202 Rear Center, original fronts: JBL 4312B Monitors.

I purchased the LSi9's as my new fronts, swithced my Yamaha to 4 ohm mood, adjusted my other speakers and tonight, the second night of owning them, while listening to a CD in 6 channel stereo mood at modest volume, the Yamaha shut down as predicted. Note to myself: Don't listen to salesmen. Many of you seem to like the RTi series. Will the RTi 4 or 6 give me improved highs? I really like the sound of the LSi9's. Had a chance to view some of the Lord of the Rings DVD and it was fantastic. I would like to stay with a book shelf speaker. If I use an Adcom GFA 5400 to drive my front LSi9's via the preamp out, can I reset my Yamaha back to 8 ohm mode for runing my other speakers? Before the shut-down I had to turn down the level of my front and rear centers and sourounds in order to turn up the volume enough to hear the LSi9's. I need to try the RTi's or buy an amp. I don't want to scrap all my speakers and start from scratch at this point. Any suggestions? Thanks to everyone for your patience. I obviously don't have the audio expertise available on this forum but then again, if you came to me for root canal treatment, your questions might sound stupid to me, but I'd give you good advise, not sarcasm.

Scientifically, that should have never happened.


Just a jab at some humor, from another thread.........sorry for your findings, but they don't differ much from many others that have tried. The LSis are simply engineered like most other top line audiophile speaker lines that love power amps with lots of guts.

audiobliss

As far as I can see, you should be able to get an Adcom 2-channel amp to hook-up to the pre-outs on your Yamaha to power the LSi9s and set the switch back to 8ohm for the other speakers.

Now, the LSi9s wouldnt' me tambre matched to your other speakers, but I don't think that's a big deal with HT.

Dennis Gardner

If you like the sound of the LSi line keep the 9s and get the external amp. You can turn the receiver back to 8 ohm to drive the other speakers since the stereo amps are now unused. This should allow you extra power to the center and surrounds from your receiver too.

Definitely a big deal for HT - you don't want the sound of
a car passing through your front soudfield to change
while passing from L to C to R :-)

audiobliss

Ahh, well....w/e...:D

I'm using Sony bookshelves for my center..but then again, I don't ever listen to surround sound stuff...

So, I guess I was wrong...what's that make, 3 times now?

Where's hEman when you need him? :rolleyes:

JGLaden- you can buy a 2ch. amp for your lsi's and use the yammie (in 8ohm mode) for the rest of your speakers. However- I strongly urge you to bypass the yammie all together and get a 5ch. amp or you could always do what I did and get a 2ch. amp and a 5ch. amp if you have 6/7.1. Although the 9's and your other speakers will be different in timbre- it won't be THAT catastrophic- BUT you should drive them all with the same quality amplifiers all the way around.

I got BOTH of my amps at a combined cost off a mere $400 (shipped) from two different sellers on ebay. Both are mint, and both kick ****.

Very few AV recievers are rated for a 4 ohm load. While not considered a huge load in the realm of high-end speakers, even the LSi9 has been measured down in the 2 ohm impedence range at certain frequencies. That is a lot to ask of a mass market AVR that "IS NOT RATED" to do so. Now THAT is a scientific fact.

Whats with all the static? By the way basic physics is my specialty.

Anyhow:
It still doesnt mean you need separates and my Harman Kardon is rated to 4 ohms and I bet anything to anyone any time any place anywhere it WILL power the LSi9s just fine. Hell, the Lexicon receiver is not a separate I guess that one sucks too and the Rotels as well. Alright everyone ditch your receivers they are all crap and wont power the Lsi9s. Forums are notorious for false information. Some moron claimed the Rti10s were incorrectly stated to have 8 ohms NOMILAL impedance simply because he measured the resistance with a multimeter. Wow now that is a real physicist in the making. IF higher quality receivers could not power the Rtis or Lsis Polk would be out of business.

Man, did you even read this thread? You're just totally not hearing what we're saying.

Hey Einstein - not everyone nor do most people listen
to movies / music at reference level :-)

hEman comparing Lexicon receivers to Yamaha and even Harman Kardon receivers is like comparing your brainpower to mine. There is no comparison.

Forums are notorious for false information? Well you said it. :rolleyes:

Oh **** I did not know that Yamaha made high current receivers. You did read my post right? Because thats what I stated wil run them and there is an alternative to that Yamaha receiver and that is a high quality high current amp receiver -just what Polk recommends and there are quite a few out there. If you you have a problem about the requirement of separates take it up with Matt.

By the way how do thosssse Rtissss foursss of yoursss sssound? Great choice in a speaker I was a marveling at them the other day. As someone likes to say around these forums I would not take those for free. But hey that just me always in the minority.

Oh, and the only thing you slap is your monkey. Stop wasting my time with your insults they add nothing to this place or I will put you in your place.

put me in my place, eh? Someone ban this **** idiot.

They evidently aren't high current enough to runs jgladden's 9s. It shutdown at modest levels. This with only a front pair.

Been there done that.

Eman - Lay off it, would you? aaharvel is making a lot more sense than you are. You're obviously just trying to get into it with someone, because you obviously haven't read this thread. (I'm not going to assume even your inteligence is so low that you could actually read this thread and still be making the posts you're making.)

You're the noobie. You're the one with the attitude. You're the one not being logical. You're the one who needs to be put in his place, not anyone else who's posting in this thread.

entertaining thread I must say.

Why don't you check out a pair of Lsi7's? If the high frequencies are what you are in love with, the Lsi9 and 7 have the same tweeter. They will be easier on your receiver to drive as well. Worth a listen. You won't need a seperate amp to power Lsi's, but it will sure help. Just something else to upgrade along the way.

cfrizz

He should just go ahead and get an amplifier. It will sound much better all the way around & he can keep it for when he does his next receiver/pre-pro upgrade.

I have to agree. The 7's are a much easier load than the 9's and sound very, very good.

I won't say the 7's are better than the 9's since I have not heard them side by side with good amplification, but they are still damn good. (hey, I have 4 of them... ) I will say for movies they are great and you won't miss a thing. For music listening there will be differences you can notice and you may prefer the 9's or the 7's. (most but not all seem to prefer the 9's)

What is it with Yamaha AVR's cutting out at modist volumes lately? I am not saying the problems are related, but still kind of odd that they are both happening at the same time.....
