STRENGTHS:
highs, mids and lows.
All ranges are so clear.

WEAKNESSES:
bring an amp fan, 4 ohm load is awesome for power and clearity but will heat up your amp.
WORTH THE FAN.....

REVIEW:
I purchased the lsi15 series and I was so impressed, I bought the entire lsi line from the lsi9s to the lsifx sourrounds.
All 4 ohms, dual drivers and the sound is so incredible I wish I could buy another home just to buy another set !!!!

I have tried every speaker from 8 to 4 ohms.

These speakers are without a doubt the best.

STRENGTHS:
Coherence, imaging, soundstaging, presence, sweetness. Their ability to reproduce the last byte of information on my favorite CDs. Last but not least: PRICE.

WEAKNESSES:
They don't possess the dynamic slam of my 10B's, but boy, do they shine in every other category I can think of!

REVIEW:
Folks, it took me considerable effort to find an upgrade for my beloved Monitor 10Bs (purchased them in '86).
I bought and quickly sold pairs of the following speakers: Monitor Audio S6, Magnepan MMG, and North Creek Okara II Upgraded Project. Nothing came close - in my price range - to matching the dynamic impact & sweetness of my 10Bs. As fate would have it, a pair of LSi15's were listed as a private sale in my hometown.
A 20 minute audition was all it took - I had finally found speakers that bested my 10Bs.
To boot, they did so by a significant margin! These speakers are giant killers. Their coherence is has to be heard to be believed; the drivers integrate seamlessly.
Their ability to reproduce every sound, shade, nuance, etc. in a recording is spot-on.
I am hearing things I'd never heard before, and this is after countless hours of critical listening to the albums I love most.
The LSi15's also perform a disappearing act -- their imaging and soundstaging are world-class. I am not one prone to using superlatives, but in this case, my choice of words is 100% warranted.
These speakers sing with a sweetness, presence, and truthfulness that has to be heard to be believed.
Are there better speakers out there? Most assuredly yes, but at what price? My guess is you'd have to spend $10k or more in order to gain a significant improvement over these babies.
The LSi15's receive my most enthusiastic recommendation. If you have the system to make these speakers shine, you won't be disappointed.

STRENGTHS:
1- The must perfect high frequency detail and warm mids I ever heard.
2- You will never hear an speaker system that sounds more realistic as a live audition as these pair of gems.

WEAKNESSES:
1- This is not really a weakness but a recomendation: Use additional subwoofers for each speaker applying a frequency cut(LPF)at 60Hz. That will improve the already tight bass.

REVIEW:
I'm been an audiophile my whole life, reading books to design speakers as a hobby and sincerely, I will put to this speaker gems at least six stars.
It's the first time I experienced what I'm been wondering to hear once in my live, clean and detail high freq., warm but not exagerated mid. freq. and tight impact bass. Believe me, there is a lot engineering on those beautifull towers, the crossovers are so well matched with each speaker handling freq.
that what you really hear is a whole and unique sound coming out of them.
If you want to obtain from them the maximum audiophile experience, used with any high definition system like SACD OR DVD-AUDIO or with your well recorded LPs.
Tried with well known brands like Telarc, Channel Classic or many others and you will listen to that detail similar to a live orchestra audition.
What about the price? Engineering and incredible quality components are only found in speakers costing five more times.
I had owned KEF, INFINITY, DCM, AR speakers and not of the cheap ones, believe me, the only way to obtain so incredible sound at so reasonable price, is putting a lot of engineering.
Well as myself an engineer I know very well that the main concern of us (engineers), is to built the best things at the lower possible cost. POLK WITH THESE LSi 15s, SURPASSED THAT DIFFICULT TASK. My must generous admiration to Mr. POLK and his group of dedicated engeneers.

STRENGTHS:
Well balanced sound and great looks.Adequate bass response for many recordings and very good mid range drivers.

WEAKNESSES:
The highs could be more pronounced and crisp.

REVIEW:
I shared my views on the pair of LSi15s that I bought two years ago.

I am in a position now to be much more objective so here goes. I love the looks of my LSi15s.

After two years I must say that I find them to be very good value for money.

I went to a stereo show in New York city and came away with the impression that most of the speakers I had heard were not any better than my 15s.

While I make no pretentions to being an audiophile, I do listen objectively and compare.

I have concluded that a pair of 28,ooo$ speakers I heard were not much better than my speakers.

Maybe twenty eight thousand dollar speakers would produce better bass, but certainly not 26000$ worth.

Polk has done a good job.Hats off. My one grouse is that the tweeters could sound brighter.

I have compensated by using a pair of moderately priced tweeters that I find compatible with the 15s.I listen to a wide variety of music but acoustic jazz mainly and I find these speakers to be especially great at producing this type of music.

I also find them to be fairly adept at reproducing reggae bass. The kick drum bass in many recordings are not as well handled though.

Generally speaking it's a very good pair of speakers for the money and I expect to have these for many years to come or at least until I hit the lotto.

התאמה

מתאימים לחללים בינוניים + {20 מטרים ומעלה}
היות והסאונד שלהם "חם" מטבעו רצוי לשלב אותם במערך סט בעל אופי קר (חד, בהיר, חריף)
לא מומלץ לשלב אותם עם הגברה חמה כגון מגברי מנורות {ואם כן אז הגברה מעל 50W} ולא כאשר יש בסט גם קומפקט היי- בריד
ניתן לשלבם במערכת היי בריד באופן מבוקר {קומפקט היי בריד או מגבר הייי בריד} 
אך לא בסט שגם ההגברה וגם הקומפקט הינם היי בריד.
מתאימים מאוד לכל סט קולנוע ביתי

מתאימים למגבר בעוצמה של 50 W ומעלה
להגברת קולנוע ביתי מתאימים לרסיברים מהחברות ימהה, ופיוניר ומי שרוצה מעט יותר חמימות אז דנון {השאר אינם משתלבים איתם נכון}
 
הצבה
לרמקולים אילו ישנו אלמנט באס הנמצא בצד הרמקולים
לאלמנט זה יש השפעה במיקומו בחדר על כמות, איכות ועוצמת הבאס
כאשר האלמנטים של הבאס נמצאים אחד כלפי השני לכיוון המרכז {כאשר כל רמקול נמצא בצד אחר של המאזין} התוצאה תהיה עם באס דומיננתי
כאשר האלנמטים יהיו כלפי חוץ התדרי האמצע והגבוהים יקבלו חיזוק
במקרה של הצבה לשל האלמנטים של הבאס כלפי חוץ רצוי שיהיו רחוקים מקיר צדדי לפחות 40 ס"מ ממנו וככל שיותר כך ייטב הדבר
הרמקולים עם באס רפלקס תחתי ולכן רצוי להרחיקם מפינות/ זוויות חדר
כמו כן מומלץ להרחיקם מקיר אחורי לפחות 20 ס"מ ומעלה
