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.

These guys work great with my powered subwoofer's, eliminating about 17 feet of speaker leads. A bit hard to sync.

I was searching for a wireless surround solution that would enable me to drive two rear Sony bookshelf speakers. I have used a Auvio(R) Wireless Rear Speaker kit in the past, but the speaker-level inputs were not the best and sound quality was marginal. I did some research and thought I would try to put together something that would pack a little more punch, as the Auvio(R) system only had 30 watts of output power. Another challenge was that I don't have any pre-outs from my 9 year old Onkyo TX-SR608 receiver. I see that car audio systems convert speaker level outputs to line outs with line level converters, so took a chance by going this route to get line outs for my rear speaker outputs. The big thing here was finding one that could handle the 100 watts coming out of my receiver. I ended up finding one that fit the bill (NVX XPLOC2). I also wanted to at least match the 100 watts from the receiver with the stereo amp at the receiver end, which is fulfilled by a Fosi Audio 100 watt amplifier. My setup results in the following: 1) Receiver surround outs butt spliced via speaker wire into the NVX PLOC2 line out converter 2) NVX PLOC2 connected via RCA cables to the iFinity Wireless Audio Transmitter 3) iFinity Wirless Audio Receiver hooked up to the Fosi Audio 100 watt amp 4) Fosi Audio 100 watt amp hooked up to my two rear surround speakers My Onkyo TX-SR608 receiver uses Audyssey room calibration and was able to automatically correct for any signal latency coming through the iFinity Wireless audio setup. The paring process took about 2 seconds between transmitter and receiver. Total setup time for the iFinity Wireless system was about 5 minutes. I have a line of sight connection that spans about 10-12 feet (3-4 meters). I have only tested the system for a single evening, but so far I have been impressed with the sound quality. There have been no signal dropouts. An interesting thing that I found was that the Audyssey calibration process sets the recommended crossover frequencies for each speaker when calibration is complete. It recommended 40 Hz for my rear surround speakers, which is the same recommendation as my primary front left and right Polk TSI 100 speakers.

I bought these to connect a pair of Klipsch R-40PM to a R-100SW subwoofer. The connection was instantaneous and flawless, it was only about 20 feet so not that much of a strain. The only problem is the occasional and sudden boom from the subwoofer, it will catch you off-guard the first few times, that nice bass from the R-100SW. I ordered some subwoofer rated RCA audio cables and the problem went away so I know it is iFinity Wireless that has having problems. Unfortunately I packed them up, and then forgot to send them back in time by 3 days so I am stuck with the trash.

I tried to put the sub 14 foot from the sound bar but the signal kept dropping so I had to put it 7 foot away and now it stays connected I’d say 95 percent of the time. Very simple to connect. When installing stuff like this I use Jurassic park it has a lot of sound so you can hear it drop out if you think it’s a concern… but for the price $39.99 your for sure getting your moneys worth. Most of the sub kits start at $100.00 to 200.00 I wanted to give it a 4 rating but a 3 fits it cause of the signal lose. Others either have better luck then I or they aren’t hearing the drop? Good luck

This review is based on 2 days of testing. Worked right out of the box, no pairing button needed. They paired themselves. I'm getting beautiful smooth deep bass from a Yamaha 581 AVR and a wharfedale D10 sub. There is of course a delay, but the YPAO config on the Yamaha compensates for that ( shows a 40 feet distance whereas it's only about 10 feet away). I don't really need line of sight in my setup - the tx and rx units are 25 feet apart and one is inside a plywood cabinet. Not getting any drops frankly - I tested for this. There is no TV though, only a far away overhead projector, maybe that's one reason that interference is less and it's working well even without line of sight. Looks cheap sure, but not thaaaaat cheap - based on the reviews I was expecting it to be made of cardboard and duct tape. It's better than that. Don't know how long it will last but I hope it does because it's awesome. Note - sub stays on all the time though.

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.

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!
