Klipsch Reference RW-12d 12" Powered Subwoofer Each w/ New box

Pros: Plenty of power

Cons: like other I have lose port also.

Other Thoughts: for 1000 dollars sub (their original price) with this quality built, I don't think so.

Pros: Same as earlier review.

Cons: Same as earlier review.

Other Thoughts: So, lying, telling my receiver that the sub was CLOSER to me, didn't advance its response... can't imagine why.
Telling it that the sub is further away, on the other hand, that should help a little.

Oh, and I finally read the ad copy closely enough to see that Klipsch mentioned the interior flange, telling us helps the response. I stand by my opinion that it's there because they had the pieces. While it may affect tuning in a positive way, the piece was clearly designed as a mounting bracket. The wide lip, and all those screw holes are not elements of classic acoustical tuning. And there's no way that flange is REDUCING turbulence.

But, sub's still working and sounding ok. Still a pretty good buy for <$300.

Pros: Price was good. I've heard much worse. Phase adjustable by 10 degree steps. Deep response, solid punch. Not painfully slow/ muddy/ bloomy, if you keep the cutoff low (above 80Hz gets yucky fast). Handles high volumes reasonably well - sound doesn't break up at higher levels. Rumbles and thunders pretty well.
Driver assembly is most of the mass of this unit. Cone is quite stiff, and magnet is massive.

Cons: Not fast or musical. Sounds behind main channels. (On my receiver, I've set the sub's distance at 5ft, which doesn't help much, but doesn't hurt. I will experiment with advancing phase, as well.) Keep the cutoff at 60 or 80Hz, and the volume a little low, and it sounds okay - not especially good, but okay.
Build quality low. I wish I could upload still photos. The MDF seems thin and low grade (I want to guess 5/8"). Reinforcement blocks are sparse, and appear weakly glued. One can see thick smears of glue near some blocks - they were slid into place, and there is some space between some blocks and cabinet walls - blocks are not all tight. When I first removed the driver, there was a chunk of loose twist-tie stuck to the magnet - I'm glad the magnet caught it before it shorted something.
The port tube (which you've read about, by now) was loose. I siliconed it in. As others have mentioned, the tube and mouth are pretty cheap plastic. Even tightly glued, the tube will wiggle, due to flex where it mounts. (The mouth is secured to the cabinet with 10 screws, but the cheap plastic flexes.) The tube has a cheap sounding ring when one taps it. As to the unused flange that someone mentioned, it is at the back of the tube. It is a heavy sleeve, with a ~1" screw flange, that would attach to an inside corner, but: it does not reach the back/top of the cabinet, and if it did it would seal the back of the tube. To recap: this big heavy flange a) cannot be used, b) should not be used. My best guess is the design team wanted to use some spare parts. The total weight of the tube feels like it applies more torque than the mount can really take; I doubt this port will still be tight and sealed in 10 years.
The 325/850W amp looks wimpy. All electronics live on a single IC board, about 6"x8". (Maybe bigger, but I've closed the sub, and don't want to open it again, as I fear the screws holding the driver will fail if I do it too many times.) On that board is a little transformer, a couple fairly big caps, and two smooth metal plates (maybe 4"x6") as heat-sinks. Again, tiny for a supposedly 325W amp.

My grille is not broken. But the posts are quite thin, and the grille doesn't stick very tightly.

Other Thoughts: I am a recovered audiophile. I've lost the snobbery, but I still have my experience, and I know good from bad. To understand my opinion, you must know that, if this sub were not fairly good, my review would be much worse. This is the first sub I've owned, but I've heard a lot of them. For a year or so I sold high-end equipment, and for 10 years I was very involved in that world. I've listened to systems that cost 50G, easy, and sold subs that cost 5k. I've never been a fan of Klipsch, and the build quality of this sub does nothing to change that. (I understand audiovox bought Klipsch. The build quality here seems consistent with that.)
I wouldn't claim this unit is fully burned in, but it's been playing (a little too loudly) for several days.
This sub sounds ok if the LPF and volume are set low. It's not that the sound breaks up at high volumes, it's just that this sub sounds best when you barely hear it. It does get pretty muddy at higher frequencies. I reckon this sub is best kept below 50-60Hz. It does well enough at adding bottom end to the sound, but it is not what I would call musical.
For less than $300, the build quality should be better, but the sound is not bad. (At $1000, this thing is a joke.) I give it 3 eggs because the sound is ok, the driver assembly seems good, and finish and features are good. Build quality deserves 2 eggs.

Pros: The pros for this sub would definitely be the great price and sound it produces. I've had others subs before and this is one of the best subs I ever had. The bass shakes and rattles things in my house, which is what i prefer also you surely feel the bass that this sub produces, also a plus. I think it is a must buy, being I ordered at 279.99 .So far well worth the price.

Cons: Now there was some cons with the sub,I had the loose port & broken grill. The loose port was an easy fix for me. I just stuck my arm inside the port and pushed it back in place. So far I've been using it and it hasn't came loose. As for the grill hopefully Newegg.com or Klipsch send me a replacement grill. Being it was broken on arrival.

Other Thoughts: Great sub, Great price, Chance of minor flaws, Like LOOSE PORT or BROKEN GRILL - EASILY FIXED!!!

Pros: Works as advertised, easily calibrated to provide awesome but now overbearing punch. Trying to convince my wife we need another.

Cons: None - required calibration but that's a given

Other Thoughts: Some complain about various broken parts upon arrival, I had no such problems.

Pros: best bang for the buck sub out there, !!! you can buy 2 of thse for some lower ened single velodyne or bowers subwoofers, i am using this sub with my $3,000.00 bowers and wilkins system with no complaints , does the job well, i have now owned these subs for 2 year now, and will shake the windows,

Cons: none beside the poor shiping, this sub is on the large size.

Other Thoughts: none

Pros: This subwoofer sounds amazing. Knocked a couple pictures off my wall because it hits so hard and low.
Led control panel is so sweet and glows blue.
My port tube wasn't loose and everything came intact and 100% working, guess its a chance you take, but its a easy fix if yours does come loose during shipping.
Price is amazing, this use to be a $1000+ subwoofer when it was first released.
You will not find anything that sounds this good for this price.

Cons: Discontinued by Klipsch. Im guessing they had too many complaints with loose port tubes and decided to stop production.

Other Thoughts: Im gonna buy another once the price goes back down.

Pros: Easy to hook-up, and easy access to the inside of the enclosure by simply removing the driver.

Cons: Mine had the loose port on arrival, easy to fix fortunately, however the LCD display is not functioning, not so easy to fix....

Other Thoughts: For the price i guess i knew what i was getting into.

Pros: Sounds excellent, Looks nice, LCD Display

Cons: Arrived with grill pegs broken off so it won't stay in place. This did not occur during shipping either, as the box it arrived in was immaculate. The port tube was also slightly out of place but was easy to remedy.

Other Thoughts: It seems every review you read about this unit basically says "sounds great but grill was broken and port tube was ajar". I'd have to agree with all of the above lol. I've contacted Klipsch regarding a possible replacement of just the grill and am waiting to hear back.

Pros: these subs go from boom to bam in a heart beat,i ordered 2 of these.ordered the original subs aprox 5 yrs ago for my basement setup,have since moved to a condo an brought these as part of my home setup (originals still in basement),it amaze me to see my guess drop there popcorn when these mother f...er hit,lol.

Cons: none i notice

Other Thoughts: great buy for me an what i like....BASS...
