Ok people I own a Yamaha RX-V650 receiver which is a high current design. Will it be able to handle the 4ohm loads the Lsi series are said to have. Many people have mentioned that the Lsi series is hard on receivers. Is this true? I also have a Samsung HDdvd-841 player that plays both sacd and dvd-a. Will this combination work for the Lsi series? Thank you for your time.

    No, it's not rated to drive 4 ohms.

    Pick up an amp. Your LSi's are starving with that receiver running them.

    welcome to the forum!

    MAYBE with LSI-7's- but even then you wouldn't be taking advantage of their true ability.

    I run a pair of 9s and a pair of 7s off an HK330 receiver and it sounds good to me... however, I am still saving up for a dedicated amp. I'm sure the amp will provide me a window towards the LSI's true potential.

    It might work at low volumes but there isn't a lot of point in spending the cash for LSI's when they won't be able to let loose with some real power. I originally used a lower end receiver to power my LSI7s and thought it sounded alright but once I got something with a little more oomph they sounded soooo much better.

    Toxis is right.

    and Joey- i would think the amps in a H/K are higher quality than ones in a Yamaha. Noticably in fact.

    I'm not surprised at all that you can push LSI's on an H/K.

    Wouldn't hold my breath on that one if I were you. my yammie is awesome and I am sure H/K makes a great product but dont under estimate Yamaha. The RX-V line is NOT sold at Best Buy but ONLY to individual dealers. There is a reason for that if you catch my drift so to speak.

    RX-v line really isnt' that different from HTR (there's plenty of threads on this out there), and the 650 really doesn't handle 4 ohm very well. It is "rated" for it, but it'll thermal shutdown at somewhat loud volumes (note: I'm not talking about stupidly loud, piss off the neighbor volumes here, either). It'll start to sound like crap well before it goes into thermal shutdown. On the other hand, at moderate volumes, it ain't a bad reciever.

    I have yet to see a receiver that'll do the LSI series justice, but you're lucky since your yammie has pre-amp outs. If you're gonna get lsi's, plan on getting some outboard amps for that bad boy. Also plenty of threads on that: Adcom, rotel, parasound, outlaw all has product that can be aquired in the $500 range (used) that'll make a big difference.

    If you really want a receiver that will do the LSi's justice, your going to have to get an older Carver. They should be in your price range. One of the bigger HK's will do a pretty decent job, but then the $$'s climb.

    The Outlaw Audio receiver (discontinued) runs for 300-400, it can push the LSi line - I'll bet on that one. A very high current design it is.

    NAD receivers can push them.

    B&K, Rotel receivers can push them.

    Sunfire, Carver receivers can push them.

    I have a Yamaha RX-V992 driving my LSi25's and it sounds great. I use the amp to drive the top in small mode and the sub pre-out to drive the LFE inputs.
    Will I get more amps and LSi's in the future? Yes. But don't let anyone tell you they won't sound great.
    I know more power(current) is better, and I will probably get some Outlaw stackables to really blow out the neighbors.....
    If your receiver has pre outs you can always add on.

    My receiver has impedance selection for 4 ohms or 8 ohms.

    Dont use the 4 ohm switch - ever.

    All it does it restrict your receiver, how much current it can use. Basically it puts your receivers on alert that demanding speakers are in use. Overall, for sound quality - its not a good idea to engage that switch. For safety, then yeah... but even then though, the receiver will go into safety mode before it catches on fire or something ;)

    I have LSI9's and a LSIC that I tried running off my RX-V1500. One speaker blew after a few weeks, probably from being underpowered. The receiver went into protection several times. I got three Outlaw M200 monoblocks 4 months ago and have had no issues. The sound is great and I get 120db output in a very large room with no distortion. No heating issues with the amps either.

    You probably blew one because you were trying to hit levels like that with a receiver.... An RX-V1500 just simply can't power LSI's like that.

    I can agree about the power amps being alot better than not having the current to push ANY speaker with authority,I thought my HTR 5790 was doing a good job pushing the system until I threw in the Bad Boys 2 dvd and the avr just went into clipping and went into protection mode. The HTR and the RXV lines are "exactly" the same units and the only difference is the face of the avr and that's all , if you need more info look at this. http://www.yamaha.com/yec/products/compare/YPAO.htm

    I looked for the maximum SPL from the LSi9's, but couldn't find it. I can tell you this, the bigger SDA's max out between 120dB to 125dB. They are bigger speakers, are more efficient and are a easier load to drive than the LSi's. See my point?

    based on the efficiency they should hit 111db at one meter & 200 watts... That's not the perfect way to figure it out, but 120 seems a little steep for the 9. Regardless, they need the power and the yammie isn't gonna cut it.

    Hello people. Looks like I may have opened up a can of worms so to speak. Did not mean to do that. However, after further research I believe a good solution to powering the Lsi9's would be the Outlaw Audio mono-blocks amps. They have them B-stock for $230 plus S&H. At 8ohms 200 watts rms and at 4ohm 300 watts rms. That is more than enough to power a set of Lsi9's and another amp to power the Lsi7's for rears. Hence, another to power the center Lsi as well and use my yammie as a preamp. $690 plus S&H is not bad at all and just look at the power you can get. The Outlaw Audio amps seem to be well received. Anybody here got any other suggestions in the "no more than" $700 price range that can out do the Outlaw Audio mono block amps???? Feel free to enlighten us.

    And the way the power is rated. HTR's are rated at 1000Hz & the RX-V at 20-20000Hz. So the RX-V ratings are more honest then the HTR line. You get the same amp in both units if you compare the same price range.

    Actually the Rx-V line rates their amps power from 20-20k rms whereas the HTR line does so at 1,000Hz and NOT across the full bandwidth. What does this mean? It means, for example, my RX-V650 rated at 95 X 7 rms is from 20 to 20, 000 Hz. The equivalent in the HTR line would have a power rating of like 120 X 7 because of that power rating at 1,000 Hz. Power wise may be exactly the same in terms of actual output BUT they are rated differently. Hope this helps.

    There is a major difference between, "just look at the power you can get" and quality sound. There's a reason those amps are so cheap.
