I have twin LSI9s and Sony Sub. How much power should I use to drive this system?
Thanks
Thanks

As much as you can afford. (including the money you get from selling the Sony sub)

Is that 2 or 4 LSi9's? Are you looking for a AVR or a power amp? Any which way you go, you'll need something capable of driving a 4 ohm load.Political Correctness'.........defined

Are you saying the more power the better. I take you feel I don't need the Sony Sub.

Two LSI9s. Looking for AVR stereo Amp. Wouldn't that be better than my 5 channel AVR since I don't want surround sound?

BTW, would four LSIs sound that much better then two? -
Slow down hoss.
First of all, what do you HAVE, and what can you spend in the forseable future? If you are going straight 2ch, why use an AVR at all? I would start looking at separates, or an integrated amp.
Second, not saying the Sony doesn't do what it's supposed to at it's price point - but the LSi series is on a much higher audio plane. I see the Sony doing more harm than good.
If you do want to use it, I'd hook it up via a low-level (rca) connection, set the crossover as low as it will go, and maybe add a little more (or replace altogther) damping inside it. As far as placement goes, somewhere between the two main speakers, with the woofer firing to either side - NOT right at you.

I agree. The Sony subs are good for the money (I have two) but the Polks are in another league. I would rather run them straight than with the sony.
Dont get an AVR for those, look for seperates or integrateds for power as Russ said.
And four LSis aren't better for 2ch.Graham -

You can get a pretty good integrated for under $150.00. A Kenwood 9100, Yamaha CA-2010, Onkyo A-8190. :rolleyes:Wayno -

In my mind you should spend at least half of the money you spent on the speakers on the electronics to drive them. $300 on the 9's amplification and pre seems to be the bare minimum in my mind.
Several members here always seems to have a good amp for sale, you might want to look around for good deals on pre's and amps.There is no genuine justice in any scheme of feeding and coddling the loafer whose only ponderable energies are devoted wholly to reproduction.

thanks for your input. As you can see, I'm a neophyte, but want good sound and am willing to spend more than the average Joe. I'm confused. I thought an AVR is a receiver (tuner, amp, preamp). Isn't that the same as an intergrated?
Thanks -

JB] When you say amplification and pre, are you talking about separate units, or a receiver. That's what I would like to have. I currently use an Onkyo TcSR501. I wish I would have known more when I bought it, but I guess I was looking down the road for surround sound. My Onkyo only has 65 watts for each channel.

Thanks, I'll keep an eye out. -

Actually, maybe. I picked up an open box Onkyo TX-8511 stereo reciever at CC for $100. It is rated at 100 watts X 2 into 8 ohms and is supposed to be able to drive 4 ohm speakers, which I can't verify as I don't have any to test it with. Also, it weighs more than some of Onkyo's lower tier AVRs even though they have 6 or 7 channels.
Admittedly, this receiver is by no means high end, but it's not total crap either. Short of a NAD integrated amp, this is probably as good as it gets for inexpensive amplification for the money in a new purchase with full warranty. -

Well, for $150 or less (especially new with warranty ) that could drive 4 ohm speakers, I don't have any other ideas.
Maybe he could do better on the used market. -
much better in the used market, check out www.audiogon.com or post a want to buy in the flea market here, have alittle patience and you will get a kick **** system.
-
Yeah, but we're only talking about $150 here. You're not exactly going to be able get a McIntosh for that, not even used.
Upon further thought, I seem to remember some Audiosource power amps and preamp/tuners on ubid.com pretty cheap. That might be a possibilty, but for more than $150 though. -
who said he needed mcintosh? theres plenty of other used brands on audiogon, and plenty of used brands here in the forum. where did you get the $150 figure from? he said he was willing to "spend more then the average joe". seperates aren't as expensive as you seem to think.

The original poster (JBlack) has never stated what his budget is...the $150 amount came up when someone posted that you could pick up various "vintage" stereo receivers/integrated for that amount. I agree with F1nut that anything purchased for $150 unless it is a truely mint piece of vintage gear will not get the job done....and even then I personally wouldn't waste my money unless I could see, feel, touch ect... the gear first
I agree that the Onkyo might drive the LSI9s but again it is probably still a marginal choice. I have a Denon DRA-685 stereo receiver that can drive the them (MSRP $500 and Denon confirmed it is rated for 4 ohms). It and the Onkyo are probably similar and better than most entry level AVRs but not as good as a stereo integrated/receiver from the likes of NAD, Cambridge or Rotel. I would look there to drive the LSI9s."Just because youre offended doesnt mean youre right." - Ricky Gervais

I just said Mac as an example of not to expect too much on that limited of a budget, even in the used market.
I do see now where somebody else and not the original poster came up with the $150 figure though. My bad.
I still say though that the Audiosource seperates that ubid always seem to have might be a viable option in that price range though for what he needs.
Also, brand spankin' new HK PA-2000 power amps can be had for less than $200 shipped all day long. They are 100 watts X 2 in bridged mode, but I don't know for sure if they can handle a 4 ohm load while bridged though. Plus HK has some refurbed 2 channel receivers at a cheap price that might would work as well. -

[JB] Hello Marker, and all you "Polk Folk." I just want to thank you all for taking the time to help steer me in the right direction (what ever it may be at this time:-) I thought you needed less power to push 4 ohms, which the LSI9s are. Anyway, it seems that an integrated (amp/preamp) is the way to go. I can forego the tuner I guess. I presume I should get at least 100 watts perchannel in whatever model I get. Thanks again :-) As an after thought, I wonder what the Polk engineers will do to improve upon the LSI9s, in the same size, if that's possible. -

I got my Rotel RB-990BX for $150 :P
Ok so it was luck and a salesman that just wanted to get rid of an older demo piece, but still. You CAN, ya just gotta look reeeeeeeeaaally hard for em! -
I have no idea why the majority of members on this forum are obsessed with wattage ratings and power amps. The Pre-amp section of a system is much much more important. It the preamp sections of the Rotel and NAD intergrated that are the big step up from common grade.
Wattage isn't as important as you might think. -

If you could ever pry the real voltage/current figures from company's then yes. I find using my ears works best.

The Simaudio i-3 intergrated amp retails for $2200 US and is rated at 100wpc....the SimAudio i-5 intergrated amp retails for $3000 US and is rated at 70wpc, every single person that has reviewed both items agree that the i-5 is a much much more powerfull intergrated.
