What customers say about "Size & Weight"

Polk Audio PSW108 Loudspeaker - Black (Renewed)

Good size unit for my room. Great clarity for the more demanding music.
The size of the speaker helps it to easily reproduce very low frequencies without distortion, and without having to crank the volume to get the effect you want.
This one is the perfect size for a small living room in an apt.
Does the job but very light in weight which makes me wonder about quality of product. My other sub is much heavier!
First thing I noticed was the weight. Very light weight so I was a little concerned right off the bat. Subs are usually heavy.

Sony SACS9 Active Subwoofer

Good build quality , it is a good size not too big not too small
For a small or average sized room, this subwoofer will easily fill the room with the deep, rich, bass sounds without overpowering the rest of the audio frequencies.
The size and design are both great, nothing too big and looks great as an addition to my current setup.
Considering the size, I would expect a little better bass performance but this product provides a nice meeting point between price and quality.
Performancce is fine, size is rather bulky.

Polk Audio PSW108 Loudspeaker - Black (Renewed)

Nice BASS!! way better than the Home Theater in a box sub that it replaced. My shows and movies have feel to them!!!
I do like this subwoofer, I have 2 of these,one for the left,one for the right channel. great with my speakers,for music and for movies also.
This thing was the perfect answer to my low bass problem.
I was a little worried about only 50 watts of power but its more than enough bass for me recommend them to anybody.
The sub sounds awesome, and is definitely enough for our medium sized living room.

Sony SACS9 Active Subwoofer

Great powerful subwoofer that has great sound throughout all frequencies.
Great sub, great price. This thing puts out an incredible amount of smooth, low frequency goodness for a great price.
this sub is able to reproduce lower frequencies than my old Klipsch. Very pleased so far with the sub.
Good sound at most frequencies. Doesn't handle lows well, but it is just a 10. Got it on sale. You should do the same. Put in a corner for the best sound
This sub is very loud and reaches some lower frequencies than most of the subs I looked at. However, at loud volumes the bass does not stay crisp and clean.

What customers say about "Features"

Polk Audio PSW108 Loudspeaker - Black (Renewed)

Look and feel of the Subwoofer is fine, blends in nice with my speakers.
The controls and setup are easy to understand. Sub produce great bass!
The sub arrived today and I tested it out. WOW. It's great! I've got to keep it turned down to about 10% on the volume knob. It really is that loud.
This looks like an ancient relic. I am afraid to hook this monster up. Looks outdated for the current technology. Ugh!
The feet on the bottom of the sub weren't screwed in perfectly straight, and adjusting their height to ensure the sub is level proves to be quite a challenge.

Sony SACS9 Active Subwoofer

There is a knob on the backside to adjust the amount of sound you'll get relative to the input source
A non-blinding, green LED light indicates power-on condition, and shows red for stand-by mode
The power-save feature should be set to ON to turn-off this subwoofer when not in use (it's a slide-switch on the backside). If you're watching a movie, turn this feature off to avoid the power-off feature switching on and off throughout the movie.
Love it, it works really well. i love the auto power off/on feature.
Easy to connect and the power save feature is great too.

What customers say about "Connectivity"

Polk Audio PSW108 Loudspeaker - Black (Renewed)

I got this sub woofer to go along with my Polk Monitor 65T tower speakers which are connected to my Pioneer VSX-45 AV receiver which make a perfect match.
I have this sub connected to a Pioneer VSX-524-K receiver with Polk T15 Book Shelf speakers. Amazing sound quality!
Polk Audio TSx 550T Tower Speakers produce amazing high and middle ranges and the PSW108 produces great low end. Well connected.
The speaker-level input and output are directly connected together, meaning that the low-frequency components are passed to your speakers in addition to the subwoofer.
I do have it plugged in with a very high end subwoofer cord as well but just can't get the sub to perform well.

Sony SACS9 Active Subwoofer

Easy connect through speaker wires for older stereo without subwoofer connection.
Bought this speaker to replace old rca speaker ....works awesome after I figured out the settings on my reciever
There are terminals for speakers but I connected my receiver directly using the line-in jack.
It comes with a cheap rca universal cord, so you don't need to buy one.
