GummickAU Posted November 29, 2018 Share Posted November 29, 2018 I was curious to know if anyone has any experience with wireless subwoofer kits? In particular I'm looking at this one on Ebay with 20% off at the moment. I'm hoping to add a PB-1000 to my setup (assuming a 2nd hand one turns up) but rather than sell my existing subwoofer I'd like to try running two. There isn't space at the front of the room for the second sub so I thought I'd try behind the seating position. With two young children about I'd prefer not to run a cable if I can get away with it.

Kaynin Posted November 30, 2018 Share Posted November 30, 2018 (edited) Can't say that I've ever gone that option, but my concern would be any delay in response by the sub. Timing is crucial for effect. Others who may have owned one may chime in here, but I don't actually know anyone who has a wireless sub.

GummickAU Posted November 30, 2018 Author Share Posted November 30, 2018 Yeah my gut feel is that they're probably a gimmick and more trouble than they're worth. If it was a bit cheaper I'd just buy it and chuck it if it wasn't up to scratch, but at $100+ it's a tad to expensive without being sure it'll work.

Satanica Posted November 30, 2018 Share Posted November 30, 2018 I couldn't get a slight low level rumble caused by in room interference to go away with mine so I ended up with a long cable going to the back of the room. And there is an advertised 13 millisecond delay that can be dialled out with equipment that has the capability. Shameless plug below. Link to comment Share on other sites More sharing options...

That being said... some wireless systems have some type of added processing delay, but that's not necessarily specific to it being wireless (wired systems can have this too). The typical delays, are much much smaller than what is audible..... but different products/setups might of course do something more extreme. 1 hour ago, Satanica said: advertised 13 millisecond That's long-ish.... but not something which you'd expect to the audible. Could you notice it? Link to comment Share on other sites More sharing options...

I think I did but it seemed minor and I know the mind can plays tricks so I'm not really sure. After just leaving it as it was for a couple of days I ended up adding 13 milliseconds of delay to my other sub-woofers and mains to compensate. This amount of of delay may cause a little bit of an issue with video sync. Link to comment Share on other sites More sharing options...

Studies have come up with quite a few different answers, but they're all >50ms for late arriving audio. (Early arriving audio is much more unacceptable) I have heard many people quote the "rule" that it's about 20ms when you're playing an instrument ... and about 80ms when you're an observer. That's detectability. Acceptability could be wider again. All that being said. I'd apply the correction too, if the option was there Link to comment Share on other sites More sharing options...

Thanks for posting. Sounds like a cable may be the only practical option after all. Link to comment Share on other sites More sharing options...

DigitalObserver Posted November 30, 2018 Share Posted November 30, 2018 Using the Rocketfish version for rears and sub. Correct me if I'm wrong but the YPAO of my Yamaha will make the correction for the actual delay will it not? Link to comment Share on other sites More sharing options...

Unfortunately my router and wireless AP are nestled behind the entertainment unit, less than a metre from the receiver. If the adaptor is susceptible to interference then that probably won't help.

The manufacturer says it's specifically not for devices in that type of band. Quote Episode claims the ES-SUB-WIRELESS' wireless signal is impervious to other Wi-Fi signals, such as 802.11 a/b/g/n, as well as microwaves and Bluetooth devices In a review, I noticed this: Quote One minor issue that I did take note of was the ES-SUB-WIRELESS' tendency to showcase or cause ground loop hums. Wire routing between the transmitter and my AV preamp proved to be the culprit and was easy enough to deal with and eliminate Link to comment Share on other sites More sharing options...
GummickAU Posted November 30, 2018 Author Share Posted November 30, 2018 Thanks for digging up that info. Perhaps it is worth a try after all. There is still a week left on the Ebay sale so plenty of time to decide. If I do get one I'll be sure to report back with the results. 1 Link to comment Share on other sites More sharing options...
