Good buy. - 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 desertcart 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 desertcart 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 desertcart 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 desertcarts return service.

You may get a mini amp for the speakers. The signal transmission is between two amps. **Q: Reading comments, it seems this would be able to transmit from my main receiver to a 2nd amp to power my surrounds - agree ?** A: Yes! It should work fine if your receiver has a low level output (preamp out or record out) and your amplifier has a preamp input or other low level inputs (i.e. CD, vhs, or tuner etc.). **Q: Can I pair one transmitter to two receivers to get stereo music out to other rooms from my main amp?** A: You only need one receiver for stereo. Two receivers will support two separate stereos, but I have not been able to fine a source for extra receivers. **Q: Does these components come with two power supplies?** A: Yes, there are 2 power supplies included. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best wireless LFE/Subwoofer kit I have tested so far.

A bit hard to sync. ### ⭐⭐⭐⭐⭐ Fantastic wireless surround solution ... but make sure you have active speakers or an amp to pair to *by C***R on May 1, 2019* 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. ## Frequently Bought Together - iFinity Wireless Audio Transmitter/Receiver for Subwoofers and Surround Speakers - Multichannel Wireless Audio Transmitter for Surround Speakers - Model 800, 4 Channels, 300' Range, Connects Any Audio Source, Better-Than Bluetooth Digital Wireless - Amphony Multichannel Wireless Audio Receiver/Amplifier for Making Passive Speakers Wireless - Model 880, Compatible with Model 800 Multi-Channel Transmitter, Better-Than Bluetooth Digital Wireless --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/11981580-ifinity-wireless-audio-transmitter-receiver-for-subwoofers-and-surround-speakers](https://www.desertcart.sg/products/11981580-ifinity-wireless-audio-transmitter-receiver-for-subwoofers-and-surround-speakers) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-15*
