Big 12 inch Long Throw Driver for longer excursion and better linearity.

Huge Hi-Roll Surrounds that support their longer excursion.

Most powered subwoofers are good for just gut-rumble and boom. Polk understands that you listen to music too so our subs are tight, precise and accurate.

4 out of 5 eggsgame changer

Pros: Shakes the heck out of my house. Easy setup.

Cons: Hmmmm

Other Thoughts: Expected this thing to be physically huge, but it is not any bigger than I would have guessed. It's a 12" speaker, so expect that diameter, plus a couple inches padding, and cube it. Pretty simple to know what you're getting.

I had a 5.0 setup with DefTech BP8B's in the front, 350s as surrounds, and Mythos Three center channel.
I thought this was sufficient, but my friends said "Trust me, get a sub, it's a game changer." After using it to watch Dark Knight Rises, The Hobbit, and Return of the King - I agree. This thing is a game changer.

Have tried it in both Dolby Digital and DTS modes, connected via LFE, and have volume set around 70%. I just have one thing to say: BOOM! this thing can just huff and puff and blow my house down. It is truly a game changer.

4 stars as I like to leave room for improvement. Maybe the user-interface could be more clear about what the different hz levels are, that is a bit over my head. I should probably just read the manual ;)

5 out of 5 eggsRollin in the Deeps

Pros: -Price (open box)
-Adel would be proud

Cons: -Open box
-Scuffed & dented box

Other Thoughts: I purchased this as the last piece in my 7.2 setup. I am loving its face off! I have a small down firing 8" for those tight punchy pows and have this up against the couch specifically to shake me durring those BOOMS! I have this set to a very low freq so it only goes off durring the deep boom and rumbles.

Other then it looking like someone hit it with a bat there is nothing I can see that is wrong with it. It works perfectly and sounds so so good.

3 out of 5 eggsVery nice at low level volume

Pros: 300 watts rms, it goes boom !

Cons: The bass is not clear unless you have it turned down to maybe 1/2 volume. If you go any louder? I get bad port noise and a vibration. The surround of the woofer is cheap foam. I expected a rubber surround. But that would be a negative.

Made in China, Cheap woofer

4 out of 5 eggsone had broken grill

Pros: Sounds really good so far.

Cons: None so far as long as Newegg can replace the broken grill...Also there were scuffs around the speaker where the grill had been pushed against the box. All maybe due to shipping since one of the handles on the box were tore.

Other Thoughts: I notice some scuffs around where the grill was pushed against the box. I will try to clean it up or the whole speaker will be returned. I'll let it play all night to see if everything else is fine. The other sub is in perfect condition & sounds great.

5 out of 5 eggsLarge room power

Pros: Auto-on, good clean bass, powerful enough to fill a large (20' wide x 32' deep x 16' high) room.

It is front driven, so if you set it on carpet, the sound doesn't get eaten.

Cons: Large, LOUD, better invite the neighbors for a few miles around.

Other Thoughts: I have this running with very clean 90's vintage JBL LX-44 3-way floor-standers (8" woofers). They are rated down to 45 Hz, but they just don't have the power to thump the room. I'm an electric bassist that loves to hear clean bass lines in rock and jazz-fusion. I used to play through a 2x15" cabinet, which would rattle windows. This sub can make me remember how that felt.

I set my Yamaha RX-V867 (95 WPC) to Xover at 100 hz, and let the Polk take the lower range. That makes the subwoofer output only send the lower frequencies to the Polk, and above 100Hz to the JBLs. So I end up with a '4 way' speaker system (titanium tweeters, 4" mid, 8" mid-bass, 12" bass).

5 out of 5 eggsPolk PSW 505

Pros: Upgraded in 2011 with one PSW 505 from 2 smaller Yamaha subs. " Great" improvement! After several months of breakin--the frequency reponse became more distinct. The sound went from "great" to "fantastic". I was so impressed that I had to add a second. I would have done it earlier, but I had to convince the "little woman" of the "enjoyment factor" of such a worthy investment. With the improvement in DVD audio/video for home theater you can't enjoy the potential in blueray unless you can present it to you ears. 49 years of marriage makes for interesting board meetings. Hooked up the second 505 and I went to "heaven". Totally balanced sub response. Not too overpowering. Remember-room dynamics and components when adding 2 of these "bad boys". I am running: Yamaha RX-A2000-7.2, Polk: CSI A6 Center, RTI A7 fronts, FXI A4 back/surrounds. Movies at $8.50 entry and $6..00 popcorn--I love home theater. You can spend more money for "meatier" subs, but these guys deliver for a great price.

Cons: Not convincing "little woman" earlier.

Other Thoughts: Don't hesitate. Veni, vidi, vici.

5 out of 5 eggsPowerhouse!

Pros: This sub is BIG, and it has a huge sound. If you love bass as much as I do this is definitely the sub for you.

It is a large sub, so make sure you have room, or make room like I did :)

Cons: None.
