What the Klipsch WA-2 Kit Actually Is
The first thing to be clear about is that the Klipsch WA-2 is not a subwoofer. It is a two piece wireless accessory kit made up of a transmitter and a receiver, and its only job is to replace the long RCA cable that normally runs from an audio video receiver to a powered subwoofer. Klipsch describes it as allowing bass extension with fewer wires, and states that the transmitter and receiver pair once on first use, after which the subwoofer is activated automatically when it is ready. The product sits in the subwoofer category on this site because that is where it is sold, but the buyer needs to already own the subwoofer.
The person this suits has a specific problem: the subwoofer sounds best on the far side of the room from the receiver, and running a cable there means lifting carpet, drilling a baseboard or taping a wire across a doorway. The WA-2 solves that and nothing else. Anyone shopping for actual bass output should be reading about a subwoofer instead, and the Klipsch R-12SW and Klipsch R-8SW are both reasonable starting points.
Compatibility Is the Whole Story
The listing is unusually blunt about compatibility, and it deserves emphasis because it is where most disappointed buyers go wrong. Compatible Devices is given as, in the listing’s own words, only Klipsch branded subwoofers with a WA-2 port, and it names Klipsch, Jamo, Energy and Mirage as the brands in question. That port is a dedicated slot on the back of certain subwoofers into which the receiver module plugs. A subwoofer without that port cannot use this kit, no matter which brand made it.
That single restriction rules out the majority of subwoofers on the market. It also rules out many Klipsch models, because the WA-2 port appeared on a specific generation of the company’s designs. Buyers should physically check the back panel of their subwoofer for a labeled WA-2 slot before ordering. Anyone whose subwoofer lacks that port needs a generic wireless kit that works over line level RCA connections instead, and the Dynasty ProAudio WSA-5RP wireless speaker kit shows how a whole speaker kit approaches the same wireless problem from a different direction.
Setup, Range and Day to Day Behavior
Klipsch describes the pairing process as simple and one time. The transmitter connects at the receiver end, the receiver module goes into the subwoofer’s WA-2 port, and the two find each other on first power up. After that, the manufacturer states, the subwoofer is activated automatically when ready, which means the kit should not need a manual pairing step every time the system is switched on. That is the correct design for a component that lives behind furniture.
The listing gives Product Dimensions of 5 inches deep by 16 inches wide by 5 inches high and a weight of 1 pound, figures which almost certainly describe the retail packaging rather than the modules themselves, since both parts are small. Warranty Type is listed as Limited, the country of origin as China, and the model number as WA-2 (120V). That voltage designation matters: this is the North American version, and buyers outside 120 volt regions need the matching variant. Reliable radio links matter in the same way for wireless designs such as the Klipsch Sub-100, which face similar interference questions.
What Wireless Costs You
Any wireless link between a receiver and a subwoofer introduces two things a cable does not: latency and the possibility of interference. Latency matters for bass because the subwoofer must stay time aligned with the main speakers, and a delay of even a few milliseconds can hollow out the crossover region. Klipsch does not publish a latency figure in this listing, so the honest position is that the number is unknown rather than good or bad. Most audio video receivers include a distance or delay setting for the subwoofer channel, which can compensate for a fixed delay once it is known.
Interference is the second consideration. The listing contradicts itself about which radio the kit uses, and that contradiction is discussed below. Whichever band it occupies, a crowded apartment building with many networks is a harder environment than a detached house. Buyers who want to avoid the question entirely should keep the cable and choose a subwoofer position within reach of it, then browse the subwoofers category for a model sized to the room.
Highlights
- Removes the long RCA cable run between an audio video receiver and a compatible subwoofer.
- Two piece transmitter and receiver design with a stated one time pairing process.
- Klipsch states the subwoofer activates automatically once paired, with no repeated setup.
- Works across the Klipsch, Jamo, Energy and Mirage brands where a WA-2 port is fitted.
- Small modules that hide behind equipment rather than adding another visible box.
- Carries a 4.1 star customer rating across 351 ratings on the source listing.
Things To Consider
The imported specification block for this product is close to unusable and should not be trusted on any point. It gives Power Source as Battery Powered, which no mains connected wireless transmitter kit would be. It lists Speaker Type as Outdoor and Surround, Speaker Size as 8 Inches and Audio Driver Type as Dynamic Driver, none of which apply to a product that contains no drivers at all. Wireless Communication Technology is given as Bluetooth while Connectivity Protocol on the same sheet says Wi-Fi, so the listing gives the radio two different ways. Control Method is listed as App, and there is no evidence of an app for this accessory. Buyers should work from the Klipsch manual, not from this block.
The real limitations are simpler. The kit is useless without a subwoofer that has the matching port, so compatibility must be confirmed first. It adds two more items that need power and can fail, where a cable cannot. It cannot improve the sound of the subwoofer it connects to, only the convenience of placing it. This product first became available in October 2011, which makes it a long standing accessory tied to a specific generation of hardware rather than a current design.
Who Should Buy It, and Who Should Not
This makes sense for one buyer only: someone who already owns a subwoofer with a WA-2 port and wants it somewhere a cable cannot reasonably go. For that person it solves a genuine and annoying problem with minimal fuss.
It makes no sense for anyone else. Buyers without a compatible subwoofer, buyers looking for more bass, and buyers building a system from scratch should ignore this and put the money toward the subwoofer itself. Compact and full size options are both covered in the Klipsch RP-1400SW, and matching the driver size to the room will do far more for the result than removing one cable.
