I have been using the Polk Audio Lsi25's.for 2 years and flat out love them.I am powering them with a higher end receiver the Marantz SR7010 and use a Marantz media player a lot of the time. I also have the Polk Lsi series for surround and center channel. I listen to mostly blues with a variety of other types of music including rock and jazz. These speakers are absolutely perfect when listening to Robert Cray, Stevie Ray Vaughan, Gary Moore or Bonnie Rait, blue's have never sounded any cleaner, excellent mids and highs. I have listened to all kinds of music with the speakers and they do excellent with all types. Now with that being said if you want a rap type bass you will need to use an external subwoofer. The subs on the speakers are excellent but they are not going to give you the boom boom boom sound that you are wanting if you like rap music. But if you like a clean hard Bass that is needed in most types of music you will love the subs on the speakers. Excellent quality styling and perfect for most types of music. Like I said I flat-out love the speakers and that is something that most music lovers could not say about speakers that they have had for over a long period. We all at one point or another think that some other type of speaker may be better, but I still have not come to that point yet.

Outstanding speaker,paid 1K from polk but would have paid more they are that good. 40+ years as an audiophile,you can spend alot more and get alot less. Run a good tube amp and watch the smile on your face on the money you just saved.

Beautiful crisp highs, smoothe midrange and nice deep rich bass. I had these speakers for three years and absolutely love them. With any pair of speakers proper setup is the key and these are no exception. I use them for two channel audio and surround sound , without a subwoofer and they sound incredible. I paid 1k direct from polk audio and they were in new condition. Best audio buy i ever had period. I listen to all types of music and yet to find a weakness anywhere.

These could be the audio value of the century. Available from Polk Direct on eBay for less than $1000. Very accurate speakers! Do a google search. You won't find many people who don't like these speakers. Many people prefer the LSi15 that has a non powered woofer. Other than that decision to make either the LSi15 or 25 will make great two channel speakers.

The lsi25 has no midrange and therefore no voice. It is a hollow sounding speaker, I unfortunately bought these over the internet and did not listen to them first. All the other reviewers on this site clearly have no ear. Please, for the love of God, do not buy this speaker.

After having these speakers for almost three months I can give my review. they are a great speaker. Many may prefer the lsi15 or lsi9 with sub over these. well for half the price of the lsi25 you can have an awesome speaker system. I bought my lsi25 from polk direct for less than 1000.00 in new condition. At that price these are the speaker buys of the century. I already have the lsi9 and the lsi15 so I can compare them all and boy do I . the lsi15 is the most neutral sounding but i find the bass a little on the light side. If placement is an issue the lsi9 with a sub may be easier to set up but if room permits the lsi25 is the way to go. They have the top end the lsi is famous for and have a nice bottom end which is adjusted properly sounds nice and full. the lsi25 dont require as much power to drive them as do the 9's or the 15's also. I think many people like to overemphasize the bass on powered subs so they have that earth shaking bass. That is great for movies but not for music. The powered subs should be felt and should not overpower the music. They give plenty of bass if adjusted properly and don't sound boomy. Although all three pairs are awesome each their own, I listen to the lsi25 the most, they just have the fullest sound in my opinion. I power them with an aragon amplifier and acurus preamp. I also have a pair of Magnepan 1.6 speakers which are also great speakers. They are a little more revealing and detailed than the polks but not as versatile as the polks as types of music you can play on them. The lsi25 work the best for me and that is what it all boils down to.

Amazing tweeters
Great looking cabinet and connectors
Power hungry use good equipment and cabling and you'll be rewarded!

Bass frequency cut off adjustment needs to be wide open or lower midrange levels are lost.

I bought these new from a local shop and set them up side by side for a comparison with my vinatge Polk SDA1C's. It didn't take long to hear how amazing the tweeter is on the LSi 25. This tweeter design has so much detail that it makes the older Polks sound veiled and narrow, and I know they didn't sound like that before the LSi25 came through the doors. The LSi 25 does require some tweaking to get the bass to fit in with this incredible tweeter. Female voices played from SACD sources leave one's ears looking for more.
One specific difference is the speed and dynamics of the music played through the LSi 25 take you on an emotional ride where in comparison to the older polks, just never got off the ground. These babies are power hungry, I'm using 400w a side at 4ohms!

Placement can be an issue do to room loading, size, and the need for a power outlet. Width of the soundstage slightly restricted but I am nit-picking here

I too, must admit that I was a little reluctant to give these a try due to Polk's "mid-fi" status. I have been looking to upgrade my HT speakers for some time and haven't been able to find a suitable replacement that works with my room both acoustically and physically. To make things a little more difficult I also decided to combine both my music and movies into the same system and room. I built our HT room from scratch to function as a dedicated HT and selected equipment to complimented the demands of movie soundtracks. With the addition of two small children I have been wanting to consolidate to free up some space and better "protect" the equipment. I set my ceiling at $6k not including a sub since I currently own several, and began looking at both used and new. Over the past year I have listened to - and auditioned in my home - many fine speakers that all have had their strengths and weakness's. If it weren't for the high impact blockbuster action soundtracks I would opt for a nice set of floor standing 2-ways that play down to 35hz or so with a very refined and "airy" sound. Unfortunately most of those aren't very dynamic and sound very congested on action movie soundtracks at anything more than very moderate volume. My favorites included the Thiel 1.5&1.6, Meadowlark Hot Rod Shearwater, and the Vienna Acoustics Bach. And then "a funny thing happened to me on the way to the boutique audio store" thing happened and I had a chance to listen to a pair of Polk LSI 15's at the local "Hi Fi's and Appliances 'R' Us" hooked up to some seriously mid-fi electronics and was quite impressed. I promptly purchased the demo pair since they aren't supposed to carry the LSI line and didn't have any others, listened to them for a week, and made use of their generous return policy. Enthused about the 15's I tried to find a dealer for the LSI line in my area and found out that we have none. So I like many others turned to the Internet and found a dealer that was willing to quickly fill my need. I ended up with a trio of 25's across the front and 3 LSI F/X in a side surround and single rear channel configuration. Very detailed with high dynamic capability and WAY under my budget with current discounting. I also purchased a pair of the LSI 9's for casual listening in the living room and am even more impressed with their performance. With the sub in the 25's turned off they sound a little thinner than the 9's running full range but if crossed over at 60hz they sound almost identical. The difference most likely has more to do with cabinet diffraction more than anything. I have had some problem getting the bass right with the three up front and ultimately ending up turning the center LSI 25 sub way down. If I could do it all over again I would purchase the 15's for the front three crossed over at 40hz and pair the system with a good sub for the last octave. That would give a little better flexibility in placement and provide a better value as well. All in all an amazing line of speakers that certainly deserve an audition.

Mike Embers was great. I ordered these speakers on a Friday and arrived at my door on Thursday. I replaced my JBL L112s with these babies. I must say they sound fan dam tastic!!!! You have to tweak the crossover though!
