I bought this sub used through a private sale. I was told it wouldn't work with my reference series tower speakers as it wouldn't go low enough.....wow, was that wrong! This is definitely a powerful sub! It digs right into the basement. My wife came in from outside to tell me I was shaking the whole house. It's rated at 300 watts but must have a very efficient driver cause it feels like twice that. It's a down firing ported design. Weighs around 80 pounds and is built solid. Only downside is the wood feet. I added rubber to the bottoms. Might be old but in no way is it out-dated.
Retailed new for $1000.

I must say that with DVD Audio, DTS and Dolby Digital 5.1 this SUB hits damn hard and solid. No boom like I've heard from other systems. Great with music too!

When new same as before, plastic feet and a rattle. Now it's perfect!

This is an update to my earlier review. I bought better feet for it and fixed the rattle by completely taking apart the box. I counter sunk wood screws at 8 locations and now the subwoofer sounds very very tight. I also took thew now dead (how was I supposed to know it would die??) plant off and set the unit by itself in the corner.

Strong, powerfull

Bad panel design

Great Sub. One and only complaint is the design of the back RCA patch panel. I use the LFE input to connect my SUB and the jack is connected so flimsily to the PCB board, that it came loose. Now it cuts in and out and needs to be serviced.

Awesome low end, great with movies and most music

Very bad rattle and cheap feet.

I bought this from Simply stereo in Palatine IL as-is for a tad under $500. When I got it home it had a bad hum, this was solved by removing the round ground prong, bye bye hum!
Unfortunately the box rattles very badly. Since it was purchased as-is, I didn't figure on much help solving the problem, so I drilled some screws into the four corners and set a very heavy house plant with a rubber coated base on it, rattle solved! That being said, it blends very well with the rest of the system. I also just purchased a Technics SA-AX7 receiver with a variable gain and output for the subwoofer, no more leaning over the sub to change crossover or gain settings! As of today the system sounds absolutely awesome! Kudo's to Klipsch for the sub, I'm not sure if I can blame them for the rattle, this was an out of box purchase, everything else Klipsch has been perfect!

Just upgraded my subwoofer from the Klipsch KSW-200 to the KSW-300. The dealerallows a full year to upgrade and when I checked their "wise buys" section
and saw that the original price for the 300 was $1,000.00 and now being sold
for $750.00, I definately had to shell out the extra $150.00 to give it a shot
(a $600.00 dollar full refund on the 200 to go towards the 300).

I must say that I am quite surprised over the improvement of the 200. By no
means was I disappointed with the 200 which is a darn good sub for the price
but this 300 really stands out. It goes down to 25hz+/-3db and the extra
4hz lower than the 29hz for the 200 is very evident.

I threw in the "Air Force One" DVD playing through my Yamaha RX-V2092 DD receiver. I have one particular scene that contains plenty of low end and LFE
effects and that is what I used to test it out. All I can say is that when
the F-16 jets arrived on the scene and came roaring accross my TV screen with all that thundering bass from their after burners...all my lights dimmed when the KSW-300 kicked in. Not to mention the incredible rumble and bass that really
shook the house. I did not have the level turned up too high and did a preliminary set up with the "Video Essentials" DVD using the test tones for
all channels including the sub/LFE. I set the sub/LFE level according to all
the other channels using a Radio Shack SPL meter. The sub level was only half
way and the sub level output (which is adjustable through the RX-V2092 receiver)
was only set at -14db (the total adjustable range is from -20db to 0db).

I'm not sure how this sub would do with music but I did not buy it for music
anyhow. My Klipsch CF-1 main speakers provide plenty of quality bass (flat
to 37hz+/3db)without the need of a sub. I really doubt that this sub would
be able to keep up with music though because of the large woofer (15").
I think as a HT sub it is quite impressive and for the price it is a very
good deal.

Don't hesitate to give it a test run :-).

Take your pictures off the wall and tie down any breakables because this sub rocks the house! Whether you're cranking some tunes or watching your favorite DVD, this sub will fulfill all of your needs. For a modest price, you can't go wrong with this one!

This is very very nice...it puts new meaning to the word "thump". I've turned this bad boy up, and let me tell you, This 15" er produces very tight bass. For Music or DVD movies...it is all thumbs up. Paid $525 new at Netmarket.
It was a toss up between Energy and Klipsch, but I chose this Klipsch sub. I think overall it sounded the best.

I thought this sub was very impressive for the price, but ended up returning it, because the build quality. There was a screw messing from the loudspeaker itself, and after the unit got a little warm from Lost in Space, the protective circuitry kept cutting in. Bought a M&K MX700 instead.
I am a total Klipsch fan, with K-Horn front mains, KV4 center channle, KTDS dipole sounds, CF1 in my bedroom, and kg-1's at my Caffe'...

Without comment to another reviewer's doubts about this sub's musical finesse, I can tell you to beware the bottom line if purchasing this item out of box. The dealer in my area spent a lot of time flexing his demo/floor savings over marked prices, and of course, once carried home, various resonances from inside the box are far more prevalent. The words of warning here are to think how much like a mask a demo subwoofer can be for making every other speaker in the demo room sound better, yet it can reveal more idosyncracies and resonant internal defects only in your own place of use. Tuning the subwoofer is akin to bobbing for apples blindfolded...what sounds good with one type of music (Bjork, electropop, techno, etc) can sound like highway expansion joints in a Yugo at 100 mph with orchestral effects. I would think 15 inch speakers the better bet for both music and theatre, but it really seems to need either a dynamic range limiter/expander, or perhaps the "dedicated" input from a Dolby 5.1 six channel processor.

Paid $499 at www.jandr.com.
I thought this was the best sub deal on the planet when I made the purchase. Stereo Review had gotten the highest SPL level of any sub previously tested (118 dB)! This is the first down firing sub I have ever placed and also the most difficult. A port on the right side of the sub complicated matters. No matter where I placed the sub, the response was not even across my listening positions. The only place I found that sounded good at my listening positions happened to be in the back of the room (supposedly the worst place for a subwoofer).

The build quality was also very suspect. The port had not been thoroughly glued and was halfway apart (got the sub factory sealed). I had to spend an hour removing the old glue and resealing the port.

After all these headaches, I can say that the sub does sound great if your listening position is in the right spot. I found the sub to sound great with music (except for club type dance music with hyper-fast bass). I had to increase the volume to obscene levels to produce noticeable port noise or distortion. For someone on a budget with a large room and strong arms, this is the sub for you.
