Product Description

Capturing all the sonic excitement of low-frequency effects, the Reference Series RW-12d Digitally Controlled Subwoofer (DCS) delivers rock-solid performances. With its class-leading technology and superior design, this hard-hitter perfectly rounds out a home theater or two-channel stereo music system.

The RW-12d shakes things up by employing a 12-inch front-firing Cerametallic woofer and a 340-watt RMS amplifier. Exclusive Corner Port Technology allows the subwoofer's port tube to be as long as possible without bending, minimizing turbulence that can cause port noise and distortion. It also allows the enclosure to be tuned to a lower frequency than would otherwise be possible to create deeper bass from a smaller cabinet. Another important element is a corner-shaped flange at the port's internal opening, which amplifies the benefits of a longer port.

For quick and easy adjustment of all functions, the RW-12d features the DCS digital user-interface that includes three equalization modes (flat, depth, and punch) and three user-adjustable presets (music, movie and night) to create specific listening preferences. Inputs L/R Line-level RCA jacks, L/R High-level speaker binding posts DCS control and feature set w/ 3 system presets Voltage 110/120 VAC 60Hz Export Voltage 220 VAC 50/60Hz Unit Dimensions - 19.2 H x 14.6 W x 21 D, Weight - 49lbs.

THe room shakes and I can feel the air this thing is pushing.
The way this sub bring life to my games, the sound of explosions and gunfire, or deep bass undertones in music or movies is just pure bliss.
If you want one of the very best subs out there, this one is one of them.

First off, I appreciate the lengths that the first reviewer went to in creating thee most thorough and informative review I've ever read. While I'm sure the author was being serious during all of that, in the end I couldn't help but giggle thinking of a scene from "Good Morning Vietnam"

"Excuse me sir. Seeing as how the VP is such a VIP, shouldn't we keep the PC on
the QT, because if it leaks to the VC, you could end up an MIA, and then we'd
all be put on KP." -Robin Willams as Adrian Cronauer

Average Joe Citizen, you are not alone my friend. My review will contain nothing more than my humble opinion written in plain english. Reading it will not require an instruction manual to understand what I am saying.

So here's my review of the Klipsch RW-12d:

I spent at least six months shopping around, reading reviews, pondering, listening to different products, and this is the one that spoke to me. Yeah, the price was more than I wanted to spend, but it was well worth it. I wanted something that was smooth and clean, but powerful enough to punch me right in the chest, and that's exactly what I got!

I'm going skip all the little intimate details as far as quoting specs, Hz, etc., and get straight to what you really wanna know:

Music: I kid you not when I say I am discovering a whole new dimension to the music I've been listening to all my life. I listen to everything from Mozart to Marilyn Manson, and it all sounded (and felt) awesome... even pipe organs sounded perfect. It doesn't overload the room with big boomy bass all the time. The sound is subtle and smooth... and when its time to hit hard, its solid, powerful, and clean.

For home theater use I am a Klipsch fan. I use their RB 81's for mains and the RS61's for surrounds with a RC 51 for my center channel. I bought the system piece by piece over a period of 3 years and purchased my first RW-12D sub 3 years ago. Since the price has come way down in the last few years I just purchased another and now run both for movies using the Klipsch system and for music using my Martin Logan's for L/R mains. I could not be happier with this system and the RW-12 in general.

The RW-12 sub represents total quality. The amp, the enclosure itself and the sonic performance is impeccable. Plenty of power for ANY type of source. Nice tight articulated bass , never flabby or boomy. Plenty of control over all aspects of your sound is available on the top panel, providing digital control over volume, equalization, crossover frequency and phase. Both RCA and wired connections are available plus the option to use 'auto on' which works very well if you don't wish to turn your sub on and off each time you use it.

I have used my first RW-12 daily for more than 3 years with ZERO problems or reliability issues. I was sorry to see Klipsch has moved on and no longer manufacturers this model so when I got the opportunity to purchase another at roughly HALF the price paid for the first I jumped at it. I didn't NEED another sub for movies OR music, but by placing each sub at the left and right position I get much improved sonic performance overall and now have even more headroom without having to crank the one sub at all.

Bottom line is, if you can't get great results with this sub your other equipment is malfunctioning or you need to experiment a bit more with placement.

To start, I must admit that I can't outdo the previous review. All I can add is that this the best subwoofer I've ever experienced. Since the price has come down, it is truly a bargain. The bass is smooth and refined. It blends with my other speakers and doesn't produce that crude booming sound that I've heard from other subs. From Klipsch Forum advice, I wired it with a single wire coming from the "Sub out" connection on my Harman Kardon AVR 3600. This is real audiophile equipment at a bargain price. In the past, I paid just as much for a low end HSU Sub which doesn't come close to matching the Klipsch sound.

First off, I puchased this LFE from NFM and this is one of their top-tier subwoofers at $800+ back in 2009-2010. I did consider building one using PartsExpress, and a few tactile transducers but my skills building is far from what I expect my end product to look like. So I suck at building enclosures. So I skipped the build to find something that was pleasing to look at. I was foremost interested in a sealed sub, and is what I asked for. NFMart sales people are not really that knowledgeable with their products, as I did most of the talking via phone after as many returns as I had.

When purchasing a LFE the important thing to look for is ported/sealed, Frequency response, and RMS. Ported or sealed is a user preference. For Frequency response anything below 16 is not nessasary, and 16hz up to 25hz the sound is felt not heard. High RMS wattage will sound louder and reproduce the sound cleaner, if the Subwoofer is rated at a lower if not equal RMS.


1. LFE= Low Frequency Effects (Emmitter) (HF is High Frequency)
2. Enclosure= Box the subwoofer is set in.
3. Subwoofer= LFE speaker
4. RMS= Root Means Square, constant wattage a speaker will receive at any time
5. Peak= Maximum wattage a speaker will receive, simply a burst of wattage at a given moment
6. SVC= Single Voice Coil
7. SPL= Sound Pressure Level, yes sound does have pressure and as descibels increase so will pressure.
8. Equilizer= a digital or analog device that incorperates crossovers to filter and adjust sound at the given amplifier.

To start:
This Enclosure is ported (This one is done right!) and atractive, and is very deceptive due to it's design.
