Question: what amplifier compatitible with Polk LSI9 speakers? I'd like to buy the Polk audio LSI9 speakers but I really don't know what amplifier can work. please help !
Document: One of these days I'd like to hear the top of the line LSi25s - I'd probably get a pair if they weren't so very heavy. Thanks, Eric, and thanks, Polk Audio.
I have a media cabinet that I needed to install some bookshelf speakers (no room for floor mounted ones). After a lot of checking around, I went with the LSi9 speakers from Polk. I really like the sound of them. Their compact size does not take away from the great sounds. And I love the cherry finish.Couple of things to be aware of ... as the other poster mentioned, these bad boys are heavy!
Polk customer service is really great, too, a true pleasure to work with this company.The speakers themselves look beautiful - the cherry has a nice classy look, it's a nice finish that reminds me of hand-rubbed Danish oil furniture.Note that these are 4 Ohm impedance speakers and not all receivers/amps are stable running 4 Ohms - check with the manufacturer of the receiver.
They are not overly bright like the B&W's are. Also they produce excellent bass that is tight, not boommy. I have a large Kef sub, that I no longer use. I am using these speakers with a NAD A/V receiver. For stands I went with Lovan Affinit 29 inch.
Hello. This is one of the first products I actually felt compelled to write a review about. I spent a couple months researching speakers before I purchased these guys. I went to most of the high end audio stores in Manhattan. I listened to Focal Chorus 806/807, Totem Rainmakers, Rega R1/R3, and the B&W 685/CM1. All are great, but I liked the Polk's because they do everything you want from a speaker.
I have no experience with other higher end system, so i cannot really tell whether this is what you deserve for the money you pay. But, i am very disappointed, and is ready to move on to a pair of Magnepan MMG. With this experience, i will not recommend LSi9 for a mid-fi system.
These are probably the best bookshelf speakers you can buy at ANY price!YEs, they are 4-ohm impedance so you need a high-current amp or receiver and yes, they are heavy but oh, what beautiful sound!oh yeah, they look at good as they sound.
The Lsi 7's are a perfect match as surround speakers for the LSi 9's. In short, the Polk LSi speakers are a steal at even their listed prices, because not only do they produce great sound, they are fantastic looking speakers. In short, I highly recommend all the speakers in the LSi line.
Polk wrote the book on customer service.We have two pairs of LSi9 speakers. I bought the first pair in March 2009 after reading wonderful reviews about them here at Amazon. We have a set of Polk SRS 3.1s  in our living room, so I didn't want to get anything else but Polks.
The price was right, so I bought them on the spot.Now comes the good part. One of the open box speakers didn't sound right. I reluctantly called  Polk Audio's customer service, expecting a run-around from voice mail hell. To my surprise on the second ring a pleasant young man named Eric answered.
Answer: Here are some brand suggestions:Parasound, NAD, Rotel, Adcom, Emotiva (eh..)Anything that is high current (45amps peak +) and puts out 150w @ 4ohms or better.  Current is more important than wattage, remember that.
