Questions & Answers

Shopper : If your TV is on a stand, is it OK to place the TV (and stand) resting on this speaker?SHOVIK S : The speaker has flat surfaces so in theory it may work. It will depend on the weight and overall size of your TV. Check the speaker dimensions to gauge the fit and appearance.Larry G : I don't know why you'd want to but the speaker is plenty strong and would be fine.
Michael M : Can this speaker sound good if pressed up against a wall?KENNETH H : Yes it will. The Power Port venting helps in every situation.
Michael M : Can this speaker sound good if pressed up against a wall?NEEL D : I believe not...for optimum sound reproduction, you need to have some space

Center Channel has great sound

Great center channel speaker for my denon. Voice was muffled with my old speaker. I no longer have to boost the center channel control to max. Recommend this as a replacement/ upgrade. Adorama experience was predictably excellent with no issues!

A worthy upgrade from the Polk CS10

I upgraded to this speaker from the CS10. This speaker is a lot beefier, pretty large unless you compare it to the 706. I wish it came in black but honestly the midnight mahogany is so dark you can barely tell its not black in most lighting. I'm no expert when it comes to how it sounds but everything seems loud and clear and I am so far enjoying it.

Great buy

Solid speaker at a great price! I think I may have committed the cardinal sin of an audiophile by mixing this with my Klipsch fronts, but this was too great of a deal to pass up! Transitions flawlessly with crossover, and looks great. It packs a punch, and delivers crisp dialogue which I never realized was lacking until I went full 7.1!

Solid center at affordable price

Sweet price on this decent center speaker, which I have been wanting for a while. Took 2 days to arrive, super fast. Hood it up with my receiver and clear sound just came out. It's a lot better than my old JBL center on music as well as movie. Solid choice for an upgrade.

A serious, high-end center channel.

A big center with a big, sweet, natural, well-defined sound. By accident, I played it with my left and right front speakers (LSIM 703s) disconnected and didn't notice the absence until the next day when I was playing with my set up.

Happy with my LSiM704C!

I replaced a Polk CS1 center with this LSiM704C. I was never quite happy with the CS1 as it was a bit flat and didn't have much presence even with the center channel turned up. Right away this was more full and provided clear dialog. Now I'm thinking about the LSiM705 speakers. Currently I'm running Polk 65T Towers. No way to test out the 705s and it's a lot of money to spend without knowing if the difference is big.

LSiM704c center speaker

I have a lot of center speakers this one is the best so far and I probably won't be looking any more. I wanted the big brother of this one but even with both on sale this was the only one in my budget. The sound is very clear and the thing I noticed that I really like is off axis it sounds like your right in front of it. Not sure how they did this but this speaker has an extremely wide dispersion area. I think that is really important when watching movies in my home theater. OH and its heavy like its made of concrete! :)

Perfect Vocal LSIM Match

The LSIM 704C is a perfect vocal match for all LSIMs and LSI speakers. The LSI center channel was not robust enough for my taste., so I never purchased it. I bounced my CS1000p center channel speaker between the RT1000I and LSI 15 systems. Now I don't have to do that any more. I'm happy with the improvements made for the LSIM 704 C.It's warm, smooth, and slightly laid back, clear vocals are great. I'm sure this speaker will sound wonderful with any quality receiver or amp.. Of course, I use a smooth sounding 120 watt Sony ES amp and there are no course or brittle highs. I listen to a lot of SACDs and DVD Audio disc which is very revealing. This speaker look as good as it sound. Since I listen to way more music than movies, and they all sound great with this speaker in the center, I can highly recommend the LSIM 704 C speaker.

Impressed

This speaker made a big difference to the overall home audio experience. I only had tower speakers and a powered subwoofer and I could barely hear the dialog without turning up the volume. Now I'm not playing with the volume constantly when watching movies. Highly recommend.

Polk Audio Lsim704c center channel speaker

9 out of 10. Sound is very clean and accurate. Replaced old center channel and movies sound much better. This a heavy duty speaker as it weights a lot and has great build quality.

Beautiful and powerful!!!!

Rich, powerful and above all clear sound. Very good level of construction and components. It's the perfect marriage with my Lsi M705. I'm excited about his performance. Highly recommended.

The All-Star Center Home Theater Speaker

Capable of making quite an impact in your home theater system. It produces the kind of wide, deep soundstage and life-sized imaging that puts you in the middle of the action on your TV's screen.

PowerPort® Technology


Designed exclusively by Polk, this specially shaped "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.

Polk Audio Center Speaker LSiM 704c

The Polk Audio LSi M704c is capable of making quite an impact in your home theater system. It produces the kind of wide, deep soundstage and life-sized imaging that puts you in the middle of the action on your TV's screen. You'll hear conversations between your favorite movie or TV show characters with pinpoint detail, complemented by special effects that cover the range from smooth bass to delicate highs. Building upon the widely acclaimed LSi family of speakers, the new LSi M series incorporates the latest developments in speaker technology, fitted into a newly designed enclosure that's beautifully sculpted and luxuriously finished.

Like all LSi M models, the 704c center channel speaker uses 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.

Polk Audio LSiM704c Features

  • Dynamic Sonic Engine (Driver & Tweeter): The heart of the new LSiM Series is this incredible enclosure-within-the-enclosure, the Dynamic Sonic Engine, that houses the mid-range driver and the Ring Radiator Tweeter. The DSE improves transient response
  • Enhanced Ring Radiator Tweeter: New Ring Radiator boasts higher power handling, extended dynamic range, improved dispersion and extended top-end response
  • Super Cell Aerated Polypropylene Cone Material: Super Cell APP has larger cells, for lighter weight and more inherent damping, plus uncompromised stiffness, for unsurpassed transient response and resonance suppression
  • Cast Aluminum Baskets: These lightweight, splayed-strut design baskets provide a rigid structure for precise alignment of the speaker's active parts, for flat response and low distortion, with no mechanical resonances or ringing
  • Orth Crossovers: Orth Crossovers feature Mylar and Polypropylene Capacitors for sparkling highs and Air Core Inductors for superior transparency
