Greatest speakers I have ever heard
Finally I got these beautiful speakers! Delivery was very fast! Only 2 days. Good job Amazon. Packaging is very good as well, good protection and easy to open. Speakers itself have a nice finish! They look awesome! As my wife said this is now the best part of our furniture :) The only minor negative think is what happened in the first day when I start listening them. The small piece with Polk Audio brand name which you see at the bottom of the front panel has fallen apart. Not enough glue probably. Should not see such things in the expensive speakers, but could happen some time. Not a big deal for me. Sound quality is excellent! I was blown away by the bass and stereo image! It's something you need to here yourself! I have another pair of Klipsh RP280 speakers, so I have compared Polk and Klipsch and this is like white and black. Polk 705 is my favorite speakers now for the stereo music and Klipsch working for the home cinema. Good job Polk Audio!

Almost perfect
Clarity and imagine is probably the best I have ever heard from a pair of tower speakers. I compared these with the svs ultra towers and the choice was difficult. The ultra has a much better base response and also the Twitters seems more pronounced and overall more musical generally. However what stands out with the lsim 705 is the overall warm tone and clean stereo musical separation . It makes for a pleasant relaxing well balanced nuteral listening experience you may need a Subwoofer to supplement the sub 35htz frequency but it is well worth the extra cost. I ended up keeping both ultra and lsim 705. I got thr lsim 705 for less than 800 for the pair , the ultra full price. I give the ultra a slight edge simply because it does everything well. The polk however is a stereo master, not a party speaker. Overall for the price I paid, I give it 5 stars, if I had paid full price I would have given it 4 for weak base response.

Sound Great
There was some minor box damage from shipping, but I didn't notice any damage to the speakers. The speaker base/platform had loose screws on both speakers upon delivery. The LSiM 705's sound and look great. I have them paired to a Rotel 100w per channel receiver. They seem a little more power hungry than my previous Polk Audio RTA 11TL's, but they play loud and clear.

These are amazing!
I finally upgraded from a Polk system that I bought 20+ years ago. Back then I bought them for about half price, due to Polk's new model coming out and have enjoyed them the entire time. When I decided to upgrade I did a lot of research and then finally caved when I saw the price drop on this previous flagship series. The LSiM 705 towers started at $2000ea, dropped to $1500ea for years (with an occasional sale) and I picked them up for $750ea, due to Polk's new model that came out (notice a pattern?). Still expensive, but I'm glad I made the purchase. I'm also running the LSiM 706c center channel, which is equally amazing! I picked up a Crown XLi1500 power amp at the same time to help run the two left and right towers (many people suggested extra power for these), but it really wasn't needed paired with my Denon X4400h AVR, which gives plenty of power. I'll still use the Crown (since I have it) to ease the potential burden on the Denon, but yeah, if you have a decent AVR you won't need additional power. I can't imagine anyone being disappointed with these speakers, especially at this price. I'm presently running a 5.2.4 setup, all Polk except the duel Subs, which are Klipsch R-1220SW. Shipped fast and packaged well. Couldn't be happier! Highly recommended!

polk nails it with lsi series successor.
The old lsi series were, and still are, killer speakers at a bargain. These new lsim 705's and 707's are nearly double the cost, but are worth every penny I paid for them and more. I got the 705's, the little sibling to the 707's. These 705's are enormous, looming, imposing, eye catching works of art. The 707's must be downright intimidatingly monstrous, scary even. You cannot go wrong with these beautiful speakers, I bought them from internet research only, never heard them till I hooked them up upon delivery. They are completely overhauled, modernized, 4- way, phenomenal sounding speakers for any genre, and volume. And they are about the best looking aesthetically, solid craftsmanship, eye candy speakers I have ever seen in person. I'm not kidding, in midnight mahogany, these are absolutely georgeous. They became the nicest piece of furniture in my house the second they crossed the threshold. You will not find a pair of towers under 8,000$ better than the new polks.
M**!
The new Standard! Truly Amazing! People are insane lol.
I can crank these loud enough to run you out of a room and with audiophile bliss!! These are my new fav speakers. I've tried dozens from Emotiva, Jamo, Warfendale, Elac uni, etc... these are really fantastic. I would place them on par with $3k-4k speakers. They are extremely attractive and most importantly sound amazing. Very balanced. I went with these over the 707 due to reading about how they compare with bass response. These are slightly tighter and offer plenty of bass. All I can say is good luck finding a better speaker for anywhere close to the price. If you are considering these...... buy them while you sill can get them

amazing sound !!
Not only are these Polk speakers beautiful to look at they ( the fit and finish is unparalleled ) the sound is simply amazing. You can spend three times the amount for speakers but why on earth would you? They came extremely well packed with no damage. A plug and play speaker that sound great right out of the box and from what i understand after the break in period they keep sounding better and better. I just couldn't be more pleased with these Polk speakers. have the most amazing sound from any floor standing spk i have ever heard. You can spend three times the amount on other speakers but why on earth would you want to.
