Polk Audio PSW108 Sound Floor Standing Subwoofer, 100W Black T30 Shelf Mount Speaker, Black

This is my first ‘real’ sub. I had a computer speaker sub before that was the ok but not in the same league.For the first day or two I had this I was strongly considering returning it. I had placed it on front of the table my speakers were on and it sounded bad. The bass was not blending with the other speakers and I was disappointed. I tried messing with the crossover point, volume, and phase. Finally I moved the sub to be beside the table so that the speaker cone was in line with my other speakers and my bass problems were fixed.I’ve read in many places that bass under about 80hz is directionless. You can place your sub anywhere close by because your ears won’t pick up the difference in location. I found that to be true when I moved the sub to be in line with the speakers. Note that my listening position is about 5 feet from the speakers so having the sub in front made it about 2 feet away so that could be a big factor too.The final verdict is that the sub is awesome for my purposes once I set the crossover point and location correctly. I have only used it for music so far and the bass goes deep and is musical. I haven’t compared it to any other sub because I haven’t had or even listened to a comparable one. I did get this on sale and consider it to be a great value for the price.

Great subwoofer especially for the money. There are many very positive professional reviews on this sub. I use two of them for great clean bass.

TLDR: Powerful with good settings through the knobs. Provides better movie and music experiences. Pad wall items with tape if you get rattling.This thing is more powerful than I thought. I still need to tweak some things with my receiver, but it’s great so far.I knew movies had visceral sounds baked in, but I don’t often go to the theater so I don’t usually experience it. After the install, I threw on Rango and got a whole different movie. Intense scenes now “feel” intense. I could feel the sound moving the couch.I was not prepared for how low frequency sounds would interact with my furniture/wall decor. There was rattling. BEST PROBLEM EVER. Be prepared to buy little rubber feet to stick behind stuff against the wall. You could also cut up the foam it came packed in and put up the pieces with rolled up tape for padding like I did.Music sounded great. I usually use headphones, my Audio-technica m40x, for listening so I get a decent experience, but not the best. Hearing and feeling bass out loud is nice and I think this sub adds something good if all you have are shelf speakers.

Edit 10/20/23:I now have the sub hooked up using the speaker inputs and outputs, and the same issue. I did find if you turned up to volume it seems to eliminate the issue. But I use my system as background music in my home office and it's just too loud during working hours. In the new pic's the one with the red LED is at soft volume, but crank it up a bit and it finally turns on, second pic.Original Review:Let me first start with: The sound is great. I like the built in crossover so you can tailor the sub to your speakers. The quality of construction is solid and I'm sure will last a long time.The only negative I see so far is the power switch. It is a three position switch, On, Auto On, Off. My set up, I am using the RCA inputs to run the audio. When in the Auto On position and I turn on the amp, the sub turns on but (here is the bad part) the sub at points during playback will shut off for no reason. I don't want to have to turn it off when not in use (for many reasons, one being where the sub is located it's not easy reaching the switch), so with the Auto On function being flakey at best I will have to struggle in order to save electricity by manually turning it on and off every time.As I typed this review, the sub cut out again while in Auto mode, the pic attached clearly shows the power switch in the middle (Auto) position but the power light is red, it's off. I know I can't prove the music is actually playing with a picture, you'll have to take my word for it.

Outstanding Bass response and easy to adjust. Level, nice wood veneer finish. Very happy with unit.

Excellent quality sub for music, movies, or anything you could possibly need a quality sub for. I'm extremely pleased with both the build quality of the box and the driver on this subwoofer. It has more than enough wattage to handle the driver with plenty of power to spare even when turning it to its max volume, which I don't recommend doing. I was able to easily connect my studio monitor speakers to it using a regular speaker wire that I had already had available, but there are plenty of various options to get it connected using all of the audio inputs. I have been into audio since being a kid in the 80's, I have Bose headphones and I use other very high end audio equipment. This was a great Christmas present from my partner this year. I will definitely be purchasing more Polk audio equipment in the future. If you're looking for a quality subwoofer for a reasonable price then Polk really did a great job making this. You won't be disappointed if you appreciate good audio.

Outstanding value for a quality sub woofer. I have read many so-called professional reviews and they do not tend to give high praise for this sub woofer, I feel they are all wrong this sub is a wolf in sheep clothing. Pack a lot of bass in a small package. Once you have set it up correctly it is amazing, setting it up does take trial and error as every room and every audio set up is just slightly different. I viewed a few you tube videos on the setup and once I found what I consider the perfect setup for me I'm blown away how well this sub hits, perfect for action movies, you can really feel and experience great sound.

I have a 7.2 surround sound, this speaker finished the .2 haha and all of my speakers are polk audio and they sound amazing. Very strong bass. One is enough but im crazy and love movies so two sounds like the movie theaters

O meu conjunto de caixas é POLK da linha XT comprei este subwoofer da linha PSW e não gostei! Compra errada!

Using the subwoofer with a new Sony a/v receiver and some existing speakers I have. The product allows me to have a great control over bass frequencies vs the passive subwoofer I previously used. A great deal for the price.

Esta reseña aplica para los modelos PSW10 y PSW108 ya que son prácticamente lo mismo, la única diferencia es el color de la parte frontal, uno es plata y otro negro.Soy aficionado al audio desde hace mas de 15 años, en donde he podido probar marcas como: JBL, Klipsch, Bose, Harman Kardon, Polk Audio, Dayton, Edifier, Sennheiser, Audio Technica, Sony, Pioneer, etc, pero recientemente he tenido interés en los subwoofers activos, hasta el momento en menos de un año he tenido 3 subwoofers diferentes, aunque los 3 han sido subwoofers económicos pero es lo ideal para después ir subiendo de nivel, y con el paso del tiempo tener un oído entrenado y que pueda percibir la diferencia de algo económico a algo de mayor calidad y precio.Los 3 subwoofers activos que he tenido han sido un Dayton Sub-1000, un Pioneer SW-8MK2 y este Polk Audio PSW108, el Dayton lo escogí por reseñas y comentarios en foros especializados como AVSForums en donde comentaban que para ellos era el mejor "Value Subwoofer" por lo que decidí darle una oportunidad y efectivamente la calidad/precio es muy buena, pero para mi gusto y para el uso que yo le doy que es escuchar música, me parecía un sonido muy exagerado al punto que tenia que apagar el subwoofer ya que después de media hora quedaba aturdido y la música no se disfrutaba, por lo que decidir seguir buscando un subwoofer mas "musical" y me encontré con el Polk PSW10 que tiene muchos buenos comentarios en Amazon USA, eBay, Newegg y demás sitios, EXCEPTO en los foros como AVSForums en donde todos opinaban que era un subwoofer muy sobrevalorado por gente que no sabe de audio, pero tanta gente no se puede equivocar, investigando mas me di cuenta que el PSW108 es lo mismo que el PSW10 solo la diferencia es el color de la parte frontal.Este subwoofer (Polk PSW108) es el subwoofer que había estado buscando, tiene un sonido refinado, balanceado y limpio, se mezcla a la perfección con los altavoces que tengas agregando esos graves que las bocinas normalmente no tienen y hacen que la música en verdad se disfrute y quieras seguir escuchando por horas, quizás lo único malo es que al principio tengas que jugar un poco con el volumen y el crossover, pero una vez encontrando el "Sweet Spot" se convierte en una delicia, tal vez para películas no sea la misma historia pero para música es perfecto.Pros:- Excelente calidad de construcción, se siente muy solido.- Sonido limpio, balanceado y refinado a volúmenes moderados y una vez encontrando el "Sweet Spot"- Precio accesibleContras:- No recomendable para salas grandes y para gente que busque bajos intensos- Después de la mitad del volumen se pierde ese refinamiento y empieza a sonar con algo de resonancia, pero por debajo de la mitad del volumen el sonido es muy bueno y suficiente para una sala o cuarto chico a medianoLo recomiendo para cuartos o salas chicas a medianas y presupuestos no muy amplios, para salas grandes seria mejor el Polk PSW505 o el BIC America F12 o un Klipsch 12hg, pero nada mejor que un SVS si tu bolsillo te lo permite.

Me gusto el producto, tiene buena calidad de materiales, funciona muy bien, en calidad precio esta muy bien. Recomendado para alguien que viene empezando y querer algo bueno sin gastar mucho.Lo tengo en la sala de un departamento de 5m X 8m y esta sobrado.

Excellent bass quality with this subwoofer.
