In the "day" many claim Polk made some good speakers.
I believe that.
On the other hand, I believe they still do.
They have a wide range to fit most needs, but they have a higher end range also.
I have a few types and for the money (or any money) Polk is hard to beat.
Polk has a wide range as they have $$ and cover the market now. The market is video these days, but they keep a hand in real audio.
The right speaker in the right place is the key and they have many choices.
I have more POLK than most, none of it is for sale.
The last I bought were the VM30. http://www.polkaudio.com/homeaudio/vm/index.php?s=vm30
Beside my big TV which they were made for, hard if not impossible to beat. In fact, even on 2 channel, will rock your boat. I like to play the DISH music channels as I ponder around. I have a Polk sub there. I have really high ceilings as my house is round. All I know is that the music is great and the TV sounds crystal clear. Things blow up and surprise me, but still, even with my old ears, I can hear the dialog. With just the TV speakers, not so much.
Sure, there are better speakers than POLK or any you might own.
I have a history with POLK and have no problem recommending them in the right application.
For the money, or any money, POLK speakers are a good choice.
In my main system here on the deck, have the POLK 4000 sub to fill in where my Sunfire CRS-3 can't go. It is not the best in the world, but better than most and better than all Sunfire subs from what I have read. It is just excellent as a musical instrument and not just a big rap woofer thing.
I like POLK.
I actually like Bose.
In the right places, these things are quite good.
