LSi9

I was recently given a pair a LSi9 speakers. I was excited to see that I could bi-amp them because I had access to a receiver that I could set up to bi-amp the fronts. It is a Sony STR-DN1020. After doing some reading, trying to find a replacement driver (explains why they were given to me) I discovered that speakers are 4ohm, but the receiver is 8ohm. I know that the speakers are going to want a lot of power. My question is, if I bi-amp them and never push them that hard (Netflix and football games) will I be ok, or will I burn something up? Also any leads on a replacement drivers would be great, I have a message in with CS but I figure I'll explore all avenues.

2) That Sony won't push them, at any level. Start shopping.
2. Happen to be listening to them right now with them set up in passive mode and other than having a driver that has a scratch to it they sound pretty dang good.
3. I'm open to shopping and since you had such strong opinions, can you give me some suggestions?
Unfortunately this is not true.

What is happening then? Is the receiver sending 110 watts to the tweeter, and then 110 watts to the drivers? Giving me separate control of highs and lows.

No. The receiver might push 110 wpc into 2 channels, but probably actually measures lower. Once you get to 5 channels lower end mass market receivers usually drop to about 35-40 wpc. On top of that, the tweeters need a lot less power than the woofers, so you are actually robbing power from the speakers that really need it to feed the tweets more than they need. Don’t do it.
The receiver will probably (maybe?) power them at moderate volumes, they just won’t sound anywhere near their potential. Just hook them up normally and then watch the volume and save up for something with more power.

Just tell us more about your goals and if these will primarily be used for music or TV/HT, etc.
I just need them for general TV watching and background music occasionally. Super small appt so don't need them to go super loud, and I have a separate active sub so I don't need them to push out a bunch of low end.
If you're just using them for TV and some music, just wire them up normally with the stock metal jumpers in place and you'll be good to go.
yamaha most entry level AVR even puts out 70 watts into 2 channels 20-20khz.....

Not suitable for high level listening for long periods, but teamed with a sub, our one little set up is VERY VERY good sounding and never strained.
I know it goes against what many in the forum say, but real life experience says it works for us.

I agree with this. For your stated purpose, I think you'll be fine with what you've got.
The good news is that if you ever decide to really get into home audio, all you have to do is give the LSi9 plenty of power and you'll think you got new speakers. They are a really nice speaker when given plenty of juice.
Good Luck!
