Polk Audio LSi M-702 F/X Surround Effects Speaker Pair -Max. Power Handling Each Watts - 200 W Home Theatre  (Black, 2.0 Channel)

Realistic, Wraparound Special Effects For Movie Night Any Movie Fan Will Tell You That Surround Speakers Are An Integral Part Of Recreating The Movie Theater Experience In Your Home. Polk's Lsi M 702 F/x Speakers Were Designed Just For That Purpose. Building Upon The Widely Acclaimed Lsi Family Of Speakers, The New Lsi M Series Incorporates The Latest Developments In Speaker Technology. The '702 F/x Speakers Excel At Delivering The Kind Of Wide, Deep Rear Soundstage That Puts You In The Action. You'll Also Notice Realistic Details Like The Zing Of Bullets Rushing Past Or The Rustle Of Leaves. Polk's Dynamic Sonic Engine: The Speaker Within A Speaker Dynamic Sonic Engine An Exploded View Of Polk's Dynamic Sonic Engine With A Tightly Spaced Tweeter And Midrange. Like The Larger, Floor-standing Lsi M Models, These Surround Speakers Each Feature Polk's Dynamic Sonic Engine. Made Up Of A 3-1/4" Midrange Driver And A 1" Ring Radiator Tweeter In Its Own Acoustically Sealed Enclosure, This Tightly Spaced Duo Acts Like A "Mini-monitor." The Precise Alignment Of The Midrange And Tweeter Allows Them To Disperse Sound Over A Wide, Uniform Area With Excellent Off-axis Response In The Critical 200 Hz To 2,000 Hz Midrange. The Ring Radiator Tweeter Features Several Improvements From The Version In The Earlier Lsi Line. A Slight Reshaping Of The Tweeter's Bullet-shaped Phase Plug Allows It To Move Even Farther Out Of The Baffle, While A Redesigned Diaphragm Has Made The Tweeter Even More Efficient. It Even Has Its Own Tuned Enclosure Within The Dynamic Sonic Engine. These Changes Result In Higher Power Handling, Extended Dynamic Range, Improved Dispersion, And Extended High-frequency Response — All The Way Up To 30,000 Hz! Advanced Driver Material For Even More Realistic Sound The Original Lsi Speakers Featured A Light, Stiff Mineral-filled Polypropylene Cone That Was "Puffed Up" With Injected Air To Form A Honeycomb-like Structure. The New Super Cell Aerated Polypropylene Uses Larger "Puffed Cells" To Create A Cone Material That's Thicker Yet Lighter Than The Original. It's Used In Both The Midrange And Woofer, Allowing Them To Move Faster And With More Efficiency. This Speaker Also Uses Proprietary Orth Crossovers To Send The Right Frequencies To The Right Drivers, Making It Extremely Efficient And Easier For Your Receiver Or Amplifier To Drive. Powerport Technology For Smooth, Deep Bass Like All Lsi M Speakers, The 6-1/2" Woofer In Each Of The '702 F/x Speakers Has Its Own Powerport®. Designed Exclusively By Polk, This Specially Designed "Cone" At The Mouth Of The Bass Port Directs Moving Air To Eliminate Bass-stealing Turbulence. No Turbulence Means No Wasted Power, Which Means More Efficient Bass Response. Grilles Off Solid Cabinet Design For Versatile Placement The '702 F/x Cabinets Are Made Of Heavily Braced 3/4" Thick Mdf With Even Thicker Front Baffles (1-1/4") To Keep Sound-coloring Resonances To A Minimum. The Magnetic Grilles Easily Snap On And Off, And They Measure Less Than 1mm Thick, So They Won't Interfere With The Sound. A Wall Distance Switch On The Back Of Each Speaker Ensures You Get The Best Possible Bass Performance Without Any "Boominess," Whether You Place Them On Tables In The Corners Of Your Room Or Mount Them On Your Walls. Achieve Startling Realism And Seamless Surround Effects When You Build A Complete Lsi M System. All Lsi M Models Feature The Same Components And Tuning, So You Can Use The Lsi M 702 F/x Surround Speakers In The Back Of Your Room With Either The Bookshelf Or Floor-standing Speakers In The Front Of Your Room For High-performance Sound, With A Matching Center Channel Speaker For Crisp Dialogue.
