Receiver powering 4-ohm LSi7's?

techguy

I am putting together a new home theater and have been reading the forum for a day or so. The more I read the more confused I become. My question: Can a Yamaha RX-V1500 receiver power the Polk LSi7 speakers? The receiver seems to only have 8-ohm or 6-ohm settings.

I think it will work fine. I know most claim you need separates, but I have been running the LSi7's, LSiC, LSiFX no problem on a denon 3801. It sounds great, though I'm sure not as good as a separate amp, but that will come later for me.

In the mean time I'm enjoying my setup very much and 100 watts/ch rating (whatever that really turns out to be) seems fine, so I'd assume the RX-V1500 would do fine as well.

By the way, the Denon is not actually rated for 4 ohms but does fine.

I have a friend running LSi9's off a yamaha receiver and is not having any problems either. Forgot themodel #, but it is about 3 years old in the $500-$600 price range.

Good luck...

THX certification requires the unit to drive down to at least 3.2 ohms. You're fine.

I would suggest separates for most of the LSi series, but the 7's seem to do pretty well on a good quality receiver.
I have an older Yammie that has the 4/8ohm switch on the back. My trio of 7's for my front stage don't seem to pose a problem with the receiver overheating. Of course, I don't drive them at theater volume levels either with the new baby in the house.

If you can swing separates, then you will be happier in the long run. However, if you can only afford a receiver, then your selection will be sufficient.

Enjoy your new system.

Optimally, separates would be a good choice for the Lsi series, but for the Lsi7's and your receiver, you're OK. Enjoy it.

I run LSi9 and LSi7 combo via my Harman Kardon 330 receiver and it sounds goooood! You should be perfectly fine with your Yammy receiver, I think your receiver has better amps than mine anyway.

I just got a pair of LSi7's for my second system and have been listening to them at normal levels using an older Onkyo prologic receiver for the last 3.5 hours with no problems at all and they sound pretty darn good...not surprising....the receiver has 110W/ch should help.:D I would think it would be ok.... unless you really want to crank the volume......they only have 2 drivers per speaker....

Yamaha always been good at driving difficult load speakers. My only problem with Yamaha over the last few years is the sound quality.

If a receiver is what you want or thats he price range you wanna be at , Denon , Rotel , Intergra all make quality receivers to compare to the Yamaha. NAD is also a good choice. Sound quality is personal.
