REL Acoustics Arrow Wireless Transmitter & Receiver – Zero-Compression SoundPath Adapter for Subwoofers, Home Theater, Multi-Room Systems – Easy Setup, Bluetooth & RCA Compatible Audio Kit

Need to setup your sub in an inconvenient location? Well, the REL Arrow has you covered. Once plugged in it simply worked immediately, and it sounds fantastic to boot. It's a little pricey, but you know how us audiophiles are. Spare no expense for great sound.

The forever question is: Would you buy this product again? And to this REL wireless transmitter I say unequivocally -- YES. Again and again. I was worried. Worried about a possible time delay, and worried if the sub would exude the same robust yet subtle sounds it had when wired. It did!

Had the Arrow for about 2-3 months now. The sound is great, identical to hard wiring my T9/x. No lag or anything when it's playing. I also don't get any interference with my myriad of other wireless devices in the house. For some reason the bass is louder with this on than wired, but since you'll be tuning this with your complete setup, it doesn't matter. The LED lights are way too bright, as other reviewers have pointed out, but I just covered mine with black electrical tape, which you can't see from across the room and in the dark. Worked great. I think a better design would have been to make the LEDs only light up when the connection is lost rather than when everything is connected and working. They're totally unnecessary since it's pretty obvious if your sub is not connected. The biggest problem is that the Arrow seems to go on some kind of internal stand-by whenever sound is not playing for a few seconds, or if sound is playing at a low volume, causing a 1-2 second lag time for the bass it starts playing again. This can be really weird when a movie or game goes quiet for a bit before a gunshot or explosion. You'll hear the gunshot/explosion through your other speakers but the sub won't play for a second or two. If you only watch movies, you will probably never notice this since there's usually some sound playing and it will keep the bass working. However, for games, especially shooters, it happens every time you pull up a menu or something and the sound stops for a few seconds. Once you close the menu and go back to shooting, the first 1-2 shots will have no bass, then you'll hear it kick in a second or two later. Ensure you hook up the high-level connection also and not just the LFE connection, since the LFE alone exacerbates the problem. I had a really bad ground loop that I couldn't fix any other way, and this is the best solution I could find so I kept mine. If you have to do wireless for your sub for a home theater, I think it will work Ok unless you're picky about perfection. I have to say I'm pretty disappointed that after paying $200+ it still has this inconvenience. They went all out to match the sound quality and latency of wired, and they totally succeeded, except for this weird issue; such a shame. It's way better than ground loop hum though at least! My sub is also quiet with this, but if I put my ear up against it I can hear a soft hum that is not normally there when the unit is wired. If you step a couple feet away you can't hear it anymore though, even in a totally silent room. There is another review saying there is a high-pitched hum, but that is from a defective unit. I had a similar issue on the first unit I received, but I contacted Rel and they replaced it for me. Their customer service was outstanding, so don't hesitate to reach out. They answered my emails within 1-2 hours and shipped me a replacement with overnight shipping and paid for the return label also.

The receiver unit is faulty It took me five solid hours of attempting to pair it before I gave up and returned it.

The idea behind the Arrow is a terrific one: lossless, low-latency audio that will never suffer irritating problems like ground-loop hum for those want to place their subwoofer in the ideal location for a room. Setup was a breeze too, especially on the speaker side where it just plugs right into a D-sub style jack. The latency really is imperceptible and the overall audio quality is fine, no distortion, no hum. The system, however, has one fatal flaw: the ENTIRE time your subwoofer is on, it injects a 1680Hz whine. And even though subwoofer speakers aren't great at playing a 1680Hz sound, they can and do play it from the Arrow unit. In a quiet room, it's quite eardrum-piercing and obnoxious. You can't NOT hear it once you know it's there. For subwoofers that cost as much as REL's and for the cost of the Arrow unit, there should be zero noise out of this thing. None. Zilch. But that's not the case. This is a fatal flaw in the system that shouldn't be there for what it costs, especially from a company that otherwise seems to know what it's doing in terms of engineering and acoustics. I had to stop using mine and switch to a hard-wired solution with isolation transformers, because it's simply unacceptable to have that kind of noise injected into my home theater audio. My speakers should not hurt my ears and give me a headache, especially at the REL price point. It's really unfortunate... I had such high hopes for this system, but it was not meant to be. Please keep working on it and make it better, REL.

Very easy to set up. Works great, has not lost connection since it synced the first time. I am using the wireless with a second T7 on LFE cable only. The first T7 is wired direct using both LFE and the speakon conection. They sound amazing.

Easy to setup and sounds great

easy to set up. works well
