I've had mine for almost 19 years and it still sounds as good as it did when I bought it but I bought a bigger house and the room it's in is around 250 sq.ft. bigger so it's time to upgrade to a 12 inch bluetooth sub and this one is going in my shop so I'll see how long it holds up in a dusty environment.

The only weakness I can think of is the frequency range and it's not really a weakness unless you listen to music that drops lower than 50hz. because that's where it rolls off. I was on a budget when I bought it and it was the best one that Circuit City had in the $100 price range. It hits hard and has good sq in it's frequency range though and it was the best $100 I've ever spent

Bought this in 2002 as a floor model and have never turned it off, still works flawless today and I receive many compliments on the sound quality, great unit with the quality to last, I will purchase another when this powerhouse goes down!!!

No weakness on this powerhouse!!!

Clear deep bass Price is the best Not boomy like most

None so far, great sub

This is a great Sub, No complaints on this product. I have own many different produsts made by sony. This sub has to be the best so far. I know most people would say theres are better because they went out and spent 500-1000 dollars give this guy a chance, it will turn some heads.

Hard pounding bass that goes much lower than the specs list,good looks don''t hurt either!

None besides the limited selection for cross-over points..60-100-200 hz..in my case 60hz is what I would use anyway.

Awesome sub at any price,will meet or exceed your need for hard pounding bass. Very tight and quick with hardly any distortion.$150.00?....A BARGIN! Highly recommended!

Having never owned a sub before, I have no other point of reference, but I enjoy the added thump and presence to my system. I was upgrading to Dolby Digital and needed the "1" of the 5.1 to make it work properly. Any affordable sub was going to do as I am not heavy into "radical bass". $150 sounded much better than $300-$400+ when purchasing a lot of other equipment. I have the sub in a large room (16 x 22) and wonder if blindfolded the $400 subs honestly sounded any better. Great price/nice sounding.

Your friends that spent $400 will swear their subs are much better.

If you want good bass at a great price, consider this unit. It only sounds expensive!

Sounds good. Have nothing to compare with. It improved the sound of my bookshelf Polk Audio dramatically.

The Auto on/off feature is bogus - it depends on the level of the signal. When I play my CD quietly - in my office, the auto on/off switches between on and off all the time. ( I use the pre amp subwoofer output of my ONKYO 575X receiver. But it is easy to fix - just turn it on/off manually. THD is about 1% - low quality amp was used.

It was the only one choice below $150 at Circuit City. Greate deal for its value. My neighbors hear it.

Strong output at the 50-70hz range,great mid range bass

does not go that low,but I knew this before buying.

First of all let me tell you that I bought this to address the mid-bass attack that lack in my rear surrounds,I have this sub hooked up to my REARS...so this review is based on this application. This sub WITH ITS 10 INCH DRIVER does a great job on hard pounding bass in the 50 to 70hz. As a matter of fact,this sub surpassed my expections WITH LITTLE OR NO DISTORTION. As a main sub or a fill-in sub at $149.00,you cant go wrong.
