The triumph of dynamic balance.
Form follows function in the shape of the LS cabinet. The delicately slanted sides add elegance and style to the appearance while aiding in the breakup of internal standing waves. The cabinet shape also enhances the diffraction control system by narrowing the baffle at the tweeter, creating even greater stability of the stereo image. The structural design of the LS series is reinforced with thick 1" baffles of non-resonant MDF and computer-designed internal bracing systems. These cabinets are rock solid when producing even the deepest bass at high power levels.
The driver cones in the LS series are a polyolefin mineral-based composite like the S series models, but with space-age aramid fibers added for a near perfect stiffness-to-weight ratio. The result is a driver of more musical accuracy. LS models also feature a SL6000 Dynamic Balance 1" trilaminate dome tweeter. Its unique composite dome is produced by a patented vapor deposition process that adds a thin layer of aluminum and stainless steel to the polyamide base. Like the most sophisticated metal dome, it provides greater frequency extension and detail, but with the smooth non-resonant character of soft domes. Finally, as a crowning touch, each LS model is equipped with gold five-way binding posts as connectors, providing long lasting non-oxidizing electrical contact with your amplifier and assuring top performance - now and in the future.
The LS70 incorporates two MW8100 Dynamic Balance 7.5" drivers in a progressive line source. When blended with an SL6000 Dynamic Balance 1" trilaminate dome tweeter, the LS70 accurately captures the vivid and emotional character of the original musical experience. For still higher performance, the LS70, with its two sets of gold plated five-way binding posts, is able to be bi-wired and bi-amped. Stereo Review's Julian Hirsch said it best: "...how did it sound? In a word, superb."

Excellent imaging, very nice balance, do well with all types of music.
Too large / obtrusive for most womens' taste.
I bought these speakers new in 1994 after owning a wide variety of quality speakers from other manufacturers. A poor college student and musician at the time, my rule was stop upgrading my speakers when I could barely carry one on my own. The LS90 was just too heavy. These beautiful towers have traveled the country with me, resided in many different rooms, and projected a diverse library of musical genres. 15 years later I have no reason to replace them. Whether it's indie rock, jazz, classical, or electronica, the LS70 will not disappoint. Powered by high-quality audio components, I'd put these up against any other towers 3 times the price. Even my wife likes them when she closes her eyes!

Solid, pure, balanced, good bass, crisp highs not brassy, no discernible bumps in freq., I am so pleased after 16 years. This is a classic which Polk should build again! Setting my Yamaha to send bass to the front and sub is fabulous.
I knew they were heavy, I knew they would not produce ALL the bass I would want before I bought them. Nothing else I looked at would do what these did close to the price and performance. They were all heavy. I don't consider this a weakness as some do, it goes with the territory. They do not vibrate on the floor when cranked!
This speaker never ceases to amaze me even after 16 years. I keep getting new receivers, DVD's, and TV's but have never had a good reason to replace these. Certainly not for a decent price. I've since tested Mirage, KEF, Klipisch, and Bose but until I have the dough for B&W, or Martin Logan I'm not doing anything. Upgraded to a Polk CS400i center to match the power of the LS70's and the sound across 15ft with my 60" Sony HDTV in the center is just plane dynamic and seamless. I think it is amusing that the old school of putting large full range speakers in the front is coming back and I'm thrilled I did not fall for the itty-bitty satelites that rob you of mid-range and depth. I smile every time I push em, and I haven't even stressed these bad boys. Way to go POLK!

These speakers are instruments in and of themselves, the whole orchestra, with true imaging and... apparent talent, if I may call it that. I listened to the orchestra on CD at home, then heard the Chicago Symphony play the same Tchaikovski pieces live, and I honestly couldn't tell the difference!
I can't pound the bass beyond what is musically desirable. Of course, for my purposes, I don't need to, but if you're asking for a weakness, that would have to be it.
I bought a pair of these beauties and they've left me wanting for nothing, except my own property so I could crank them up and maybe have a reason to get a sub... They were selected for the price/performance and with a preference for companies like Polk which lead the pack in research and development. I wanted a speaker capable of good action movie sound, but with an emphasis on musicality. With the angled sides and potent drivers, these speakers do everything I need them to do, effortlessly; also, they sport the sonic purity that Polk is so hyped about. I've never been disappointed by these, except when I wanted to turn the bass up in a non-musical way just to make noise. These don't make noise... they're musically pure until they pop, and I didn't want to push them that far...

sound,highs,mids, good bass for music wont burn your wallet up, retail about 699. ea
weak grill tabs add a sub for movies, not really a weakness, just advice
OK, so its been 12, yes twelve years since the purchase of these angels.I have really been chewing at the bit to up-grade to the lsi series, but quite honestly, I will need better ears to hear any difference. I figured 4500.00 for a new 5 channel set up, no thanks.I did the 5 channel in 94 and with the cs350 center and lsfx rears, The top of the line back then ( and in my opinion todays standards in high end audio) They have all the sound, from Van Halen, to Garth Brooks, to Terminator 3, never a problem never a disappointment. Long live VH
