Yamaha 2400 w/ LSi9's?

I just bought a Yamaha 2400 to replace an old unit that was at least 10 years old. I was very happy with the old receiver, but thought it was time to upgrade to digital. At the same time, I upgraded my speakers with Polk LSi9's, and also the LSiC for the center channel. They were out of the sub when I made this purchase, and I don't have one yet. I wasn't using rears before, but picked up Kipsch RSX-4's. I made this purchase without much knowledge of ohms (the LSi9's beind 4 ohm, and the Klipsch being 8), or mixing of different brands. So I didn't even thing about the power required for the 4 ohm's. The setup seems to work OK, though the receiver gets fairly warm on top. I'd appreciate any feedback as to whether this setup makes sense, needs more power, etc. I talked to the sales guy after learning about the 4 ohm issue, and he believes they will work fine.

I used to own the Yamaha RX-V1300 and it had a 4 ohm switch on the back that one could toggle for LSi 9 (4 ohm) use.
Looks like the RX-V2400 is rated for 6 ohm use min now. Did you select the 6 ohm setting per page 23 of your owner's manual? I would do so. If your Yamaha dealer is comfortable with it I wouldn't worry to much if you don't listen at extreme levels for long periods of time. If your unit starts going into protect mode or shutting down I would consult with your Yamaha dealer.

not all sales guys really know what they're talking about, I'm a sales guy and if you had asked me I would have told you that the receiver will have a hard time powering the lsi9's on its own as they are relatively ineffecient speakers as well as having a 4ohm load, there are very few receivers that will be able to provide enough power for those speakers. Also, mixing brands, even if it's just from front to back is probably not a good idea, and especially not a good idea with speakers that sound so different from each other. Klipsch and Polks LSI's are very different sounding speakers. If you are within the return policy period I would suggest one of four things. Option 1)Keep the Reciever and return the Klipsch speakers and pick up something that will blend better with the LSI's and then order three mono blocks from Outlaw audio and hunt for two hundred watt amps three of them, to really make the most of the LSI's. Option 2) Return both the reciever and Klipsch speakers and look into getting a five channel amp and a preamp or or a five channel amp and say an hk230 because it has preouts. Option 3) Keep the receiver and the klipsch rears and return the Polks then go klipsch for the rest of your system, they are highly effecient speakers and some people love the way they sound. They are a very robust, foward, and bright speaker, it's the brightness that really makes them so different from the LSI's in term of tonal quality. Option 4) Just return the Klipsch for different rear speakers, and keep your receiver, if it plays at volumes that make you happy without overheating (i.e. too hot to touch) then you should keep it as you're happy with it, if not, then it should go.

I believe fireshoes ran a RXV-2400 with LSi 15 for a while without problems. You should send him a PM to ask his personal opinion.
I do agree though. The 2400 is not the best choice for the LSi in terms of power and impedance handling; but that doesn't mean that it will not work either.
I would also call Yamaha customer service directly. -
The 2400 does fine as far as receivers go. I had a 7.1 LSi system going on mine. I'm sure they sound fine now, but they will sound a lot better with seperates. You'll be okay with the 2400 now, but sometime you should consider adding an amp. Mazeroth has been very happy with the amp he got off of ebay for $250. I think it's a Crown and is 400 x 2.

Thanks for the quick replies. I did e-mail Yamaha over the weekend and they responded today with the following: "In response to your email: Yes, all Yamaha AV receivers are stable
down to, but not below 4 ohms. We recommend that you use only speakers with a minimum of 4 ohms. Also, please make sure that the impedance selector switch is set to the correct position recommended by the owner's manual. If you have a combination of 4, 6 , and 8 ohm speakers, set your receiver to 8 ohms."
So, although not an option on the receivers, I think they are saying 4 ohms could be OK, but that I should set the receiver to 8 ohms b/c the others (rear) are 8. I had initially set it to 6, incorrectly thinking I should be closer too the lower ohms.
Technically, I believe I'm still in the return window, but may face a re-stocking fee I'd rather avoid. Also, the room is approx. 300 sq. ft. and its a city apt., so I generally can't go too loud for too long. So I'm sure I won't be using these fully for a while.
If I go the add'l amp. route, is this an easy connect, to the receiver? Or is this in lieu of? -
As long as your receiver has pre-outs for a seperate amp it's easy as pie.
no pre-outs = no external amp -
If you are in a return window it may be wise to consider returning it. You can add an external amp easily because you do have preouts or you can get a receiver / seperates that can run the LSi.
Some other companies to look for in amps and receivers are:
NAD, Outlaw, Rotel, Parasound, B&K.
I know it's a tough decision to return and get a restocking fee charged to you. If you like the way it sounds right now and don't play to loud, you should be fine based on the input that you have received.
