Great sound. Verry low frequency 20hz! Natural sound, not big boom bass. Tight bass. Verry powerfull. Great for large room.

As an old 23 years old subwoofer, it had some flaws. I bought it mai 2020. The spider was loose, it produced a scratching sound with no bass at all. I repaired it with epoxy. Now it plays like new. - - It is a really good sub for music, great for a big room. I paired it with a pair of Paradigm Reference Active 450LR and a NAD C165BEE preamp. It take a powerfull sub to go allong such masterpiece of speakers. The down firing port is nice. The frequency as low as 20hz is rare for that line os modest cost subwoofers. Many subwoofer that cost twice the price don't even go that low.

Fairly clean and tight at moderate levels.

At louder levels, especially playing deep base, the sub bottoms out every time.

This sub is very average. Not nearly as nice as what i would expect from a $649 retail sub. I've recently tested $1000ish subs and found that it's a night and day diffence (maybe it should be for the difference in price). I am currently selling my Polk to buy a Sunfire MKII ($1399 retail). Thankfully i'll be buying this one wholesale!

Wonderful Sound Quality for Music

Lacked "Umph" for Home Theater

This is a very clean sounding sub. I've never been disappointed with any polk product but this sub appears to lack power. The BU-120 is a sub that you felt, however the quality of the sound was lacking. The Infinity was okay for theater but was awful for music where as the PSW 150 was great for music nicely complimenting both my RT 7s and RT 55s but would not shake the room as the Infinity did for home theater. I took it back because I wanted a unit that would do both. I'm going to purchase a Velodine CT 120 to fit the bill.

I purchased the Polk because my Infinity BU-120 self destucted at 3:30am. My wife woke me up thinking the furnance was going to blow. I was in quick agreement. Stay away from this unit regardless of how inexpensive you can get one. There is a reason they are giving them away these days.

The polk is a real nice unit. I loved the smoothness this sub delivered but this is in part is it's weakness also. It is so smooth that it fails to deliver a significant "umph" when you would like.

GReat Sub,Very "Tight" and musical. The BASS just doesn't get "Muddy" and is delivered with great authority!!
Use it with a set of Polk RT-55s. A great combination.

Use the PSW-150 in my theater room and have been very satisfied with it. Replaced a Velodyne sub with it. The power rating seems to be very conservative as I find the volume usually rests around 1/2 way and the best crossover setting is around 65-70 hz. Unfortunately, I am awaiting delivery of AR-1's with 500w powered subs in them and expect I'll no longer need the Polk. I did not pay anything near msrp and because of that I feel as if it is very good value.

Solid Build

I've read a few bad reviews here and thought I'd give my opinion. We've been using this sub for about 3 years and have had no problems whatsoever. One thing to keep in mind is that this is a speaker and is capable of being over-driven, (and blown up repetitively) as can be done to any speaker. I run it with the Amp turned up about 3/4 of the way and the crossover set to about 70Hz. I beat the heck out of this thing & think it's a great buy for the relatively low cost compared to some of the other subs in the same price range.

This sub has remained wonderfully tight and works well for HT as well as for music.

During our first year or so of usage this sub gave us 'hum' when the 'auto-on' was activated, but not receiving a signal. I would approach the sub and give it a firm 'whap' with the side of my fist and the 'hum would go away.

I guessed there was some external noise from the power line and knew the whole system could benefit from some line conditioning. We purchased a Monster Cable line conditioner, the HTS 5000, plugged in the sub, and never noticed the hum again.

Love this sub, great deal for the $$$.

Have two of these babies in stereo mode using them as a crossover onto the mains (full range three way speakers). That's how everybody that claims for good bass should connect active subwoofers (ideal an external crossover, but well... if you have the money). This configuration, will blow your ears, both in music and movies. Has all the power in the 50-60 Hz range, where all the subjective bass is. Won't shake your house, sure, but won't distress and sure you can have impact on effects. Has all the tonal definition, overhang and rythm and pace that good bass needs in music. If you love music and want some wowbass at the movies, for the price, you can have two (the more the best) and save money for a good preamplifier. Go for it.

I don't think the PSW150 can be beat in this price range. Deep and tight. VERY little distortion. Great buy!

Price and excellent build quality.

Quantity of bass for 200 watts rating

I was bargain hunting at Circuit City Stores and found this sub for a great price. The MSRP is $650 and it's build quality is excellent. It weighs over 40 lbs and has an attractive simulated black wood finish. I bought it to suppliment bass in my home theater. I already own a Velodyne CT 100 so I daisy chained the Polk. As previous reviewers have commented, this sub lacks the volume for home theater but produced tight smooth bass. It cannot compete with the Velodyne even with the 200 watts rating of the Polk. It was rated well by Widescreen Review (1/98). This sub has been discontinued and it is a bargain for $200. However, I returned it and plan to buy another Velodyne.
