iFinity Wireless Audio Transmitter/Receiver for Subwoofers and Surround Speakers

Just recieved my units yesterday, so keep in mind this review is on initial impressions and about 4 hours of testing. Saying that: This is the first wireless transmitter I have found that sends my LFE channel (subwoofer) across the room without distortion, humm or weird hitches. I was very nervous ordering these honestly because of a few things: 1. The unit does look cheap, no getting around that, I hope the company does a redesign for them as they look like a homemade contraption. Getting rid of the cheap grey plastic for something sleeker would be a start. Additionally, I would suggest to the seller to stop including the RCA cables if you cant put quality ones into the box, they just lower the quality perception of the product. I will say the units are smaller than you think, the picture makes them look rather large, when in fact they are very tiny. 2. The lack of Amazon prime and thus a easy return policy. Things like this are very hit and miss, I've tried 3 different wireless solutions, all ended up getting returned because they would either cut out or introduced noise into the signal (or worse, loss some of the signal, amazing how many of these wireless transmitters cant send information under 60hz). To the seller: Please consider becoming part of Prime or offering a better return policy, I almost avoided this product all together assuming it would be as bad as every other transmitter and I'd have a fight on my hands to return it. The only reason I tried yours was I have already test all the other ones for sale! So with those thoughts out of the way, let's get to the positives: 1. The unit is transmitting the full signal. I did a full range test on the receiver as soon as it arrived, the product description is correct that its transmitting all the way down to 2hz. Very nice given all other units on amazon I tested had a hard drop off at 20hz. the importance of sub 20hz is likely marginal, however, I felt the difference between a straight wired sound vs this unit was barely noticeable, while other units there was something lacking. 2. No drop outs or clicks or boops or any other weird signal distortion sounds. I placed the transmitter in several different areas, behind my receiver, next to a network switch, next to a Xbox One, next to an HTPC and directly behind our Sony X940c. No drops in signal. The receiver sat under the subwoofer which is 14ft away behind our couch. 3. Unlike every other wireless unit I've tried this unit instantly turned on the subwoofer once an LFE signal was sent. Other units would often fail to turn on the sub from its autopower mode, or have a long delay. This one acts like a straight wire connection. 4. The dual channel input and output work great for dual subs. I have run both of my subs connected to it, with my Denon x4200w calibrating each independently. No issues. Calibration distance came in at 23.5ft, so I'm guessing we are seeing a 10-20ms delay in the signal (wired distance came in at 4ft) I will keep this review updated based on how the product holds together over the next year. Needless to say, I recommend the unit over any other wireless units currently for sale on amazon or at Best Buy (Here is looking at you, you horrible Rocketfish transmitter). I hope the seller makes it easier for people to trust the product and brand by offering it with amazons return service.

As many other reviewers have indicated, this device works very well. Its easy to pair the transmitter and receiver, and the sound quality seems very good. I measured it down about one dB at 20KHz, and flat down to 7 Hz (I didn't look lower than that.) The receiver AC output voltage for each channel is an exact match for the transmitter input voltage. I thought the supplied RCA cables were fine -- maybe they've upgraded them after getting so many negative reviews. Based on all this I would give it 5 stars, but . . . The one problem is that the receiver output has a couple of volts DC on top of it, which looks like the result of operating with a single ended output device without a coupling capacitor to block DC. This is fine as long as your amplifier has a blocking capacitor at the input, but otherwise your amp will be dealing with a big DC input voltage and maybe even trying to output that voltage, which would push woofers to their limit, to say the least. For that flaw, only 4 stars! Follow-up 12-19-21 I've gone back and measured the output of this device again, based on some other reviews discussing possible limits to its maximum input and output signal voltages. Here's the thing, the maximum input voltage it can handle is 1.0 v rms. After that the output signal begins to clip. This could be a problem because many setups will use input voltages up to 2 volts or more. The distortion if you exceed the 1 volt input limit would be quite severe. Secondly, other reviews include discussions of the time delay this device puts into the system. I measured it and it is a big 31.3 msec between an input and an output signal. This could be a problem if you're trying to time align your woofer/subwoofer, or at least your AV receiver would have to be able to compensate for this large signal delay. For what its worth, the output signal is also inverted, although that probably hardly matters with a 31 msec delay!

Bought one set for a remote subwoofer installation, used the mono port only, which is the left RCA terminal; worked perfectly. Really just basically plug and play. It is true, as other mention, that the little gray boxes look somewhat cheap, however, they are small and can be discretely placed out of sight. I didn't encounter any problems with latency (delay) or intermitting signal, it has been very steady, and, in my case, contrary to what other reviewers have said, I had no problem with these working without a line of sight. The units are light, easily attachable with Scotch's velcro-type fasteners, the transmitter under the shelf where my AVR sits and the receiver tucked behind the subwoofer with all sorts of "obstacles" in between them. I am ordering another one for my fourth subwoofer (2nd wireless). Onto of everything it is the least expensive solution available of this type and has no protruding antennae, still works like a charm. Some reviewers mention that it comes with cheap cables; they are not bad, plus, I didn't expect it to come with any RCA cables. Really, the only con (for me) is the super bright red status light, which in dark environments is quite noticeable. You can always place a piece of tape on top if it becomes a nuisance. Five stars for functionality regardless of the minor cons mentioned. Overall, great product, very happy with it.

This works for my powered sub, but if there is anything between the receiver and transmitter, it cuts out. My receiver is less than 20' from the transmitter, and the audio cuts out, unless the receiver has direct line of sight of the transmitter. A couch, wood door on an entertainment center, etc. blocks the signal.

I think it's really funny that the manufacturer claims effective distance of 200 ft. range line of sight and 50 ft. through walls or ceilings. I have these set up NINE FEET AWAY from each other, completely unobstructed line of sight and the sound cuts in and out like morse code. I cannot get more than 1-2 consecutive seconds of the subwoofer being engaged before it starts pitter-pattering. You get what you pay for, I guess. "The wireless transmission employs advanced adaptive frequency hopping. It avoids frequency channels occupied by other wireless devices and is highly robust against wireless interference" must be pulled from another product description because it does not apply to these. I have, at max, the TV app and the router on, or the Xbox and the router on at any given time and I cannot for the life of me get a steady signal. I can't possibly place these any closer. It's infuriating how inefficient the product is. Not even going try to contact the seller or Amazon, based on what other reviewers have said about the process. Chalking them up as a loss and tossing them in the random electronics/cable box in the garage. If I am ever in a place where they would be the ONLY wireless device in the vicinity, maybe I'll give them another shot. Ordering a second SVS sub and trying their SoundPath wireless transmitters. Save yourself the time and shell out a few more dollars for a different solution. I understand something like this is never going to be 100% perfect but the performance is laughable.

Like many others I have bought cheaper transmitters and receivers to power my sub-woofer and have been deeply disappointed. The three problems have always been the lack of distance the signal would travel if interrupted by walls, the amount of distortion and hum on the speaker and the level of signal interruption when the signal was broken by someone walking in between the transmitter and receiver. These amazingly small devices, with no aerials, far exceed the performance of anything I have previously tried and are now successfully providing a clean, silent signal to my sub-woofer. They are more expensive than many other systems, I bought mine from America and had to buy power plug adaptors which saved £30 vs UK prices, but they actually work which in the end is all that counts. When it comes to syncing these couldn't be easier, you just turn them both on and they sync pretty much immediately, as long as they are in range, if you need to encourage them they have a small sync button. One word of caution, their range through walls, like all the systems I've tried, is pretty limited, not much more than 10m at best, but no doubt this improves dramatically with a line of sight signal.

I previously gave it 1 star. The first day I had it, it worked great and allowed me to get my sub back in the living room with the rest of the speakers where we listen to music and watch movies. It really was great while it was working. BUT, alas, ...it died a day later. I called the support number and left a message met with an automated response that all lines were busy and that they would call me back. (Clouds rolling in...) Much to my surprise, they called my back just like they said they would!! ...AND they are sending out a second unit. I will give it another shot because it is pretty slick to have that sub in the living room without wires going everywhere. Sometimes a bad unit sneaks out, that is just a part of life. They offered me a refund too and said they were just interested in doing whatever made me happy, so I opted for a second try, partially as a reward to a company that actually supports their products. Refreshing. This was all taken care of within about 2 hours of me calling in (maybe less). I'll update this if something changes but for now I summarize that 1)Support seems very good, and without accents and bad overseas connections 2)The quality of the sound was great when it was working. Honestly, for me anyways, bass just has to be there in the background. Clarity isn't all that important although I'm sure some audiophiles will disagree. In any case, it sounded as good as it did connected directly to the receiver.

Easy to setup. Does have time delay but easy to overcome by increasing the distance the speakers are away from you. At least double the distance of the mains. I'm using this for my rear speakers so I just set the receiver to 7 channel stereo and adjusted until the music was in sync. Audio quality is good. No interference nor static in my home but others may get some. (Less than 30' away) The level of out was a little bit low, which was okay for me as my amp had a sensitivity/trim control and just turned them up. It seems to be well made even though plastic and should last a good long time.
