The following “workaround” can improve the switch-on behaviour even at lower levels:
set the mode switch of the KC62 to "Manual
select the KC62 as the connected subwoofer in the Connect app
configure the High Pass Filter to 70 Hz in the App
set the low pass filter for the sub to 250 Hz in the app.
set the crossover control on the subwoofer itself to 45 Hz.
turn the volume control on the subwoofer to the 3 o’clock position.
If the switch-on behaviour still causes problems, you can increase the output level (subwoofer gain) in the app and reduce the volume accordingly with the control on the subwoofer.
Yes, the volume setting is wholly individual from room to room. 1 o’clock is sufficient for me at neutral (0dB) gain setting. Also experiment with the subs woofers firing either the length or the width of the room. I have them facing towards me same as the speakers.
I have heard reports that using the workaround makes the bass sound horrible. I do know it wakes the sub almost immediately.
I recently acquired a mic and some software to see what some audio analysis may show; however, I am a complete neophyte as far as this is concerned. Any suggestions?
KEF LS50W version 1 user here paired with a couple of B&W ASW608 subwoofers (small, white, cheap especially at the bargain price I got them for, and intended to be a stopgap purchase until I worked out what I really wanted but are now well into year 3 of their residence in my living room). I would have upgraded to a pair of LS50W v2 plus matching stands and a pair of KC62 over a year ago now had it not been for this staying-in-standby mode so, if anyone from KEF is still monitoring these forums, that’s over £5K of revenue sitting on the sidelines from me alone just because of this one issue.
I probably won’t bother making serious efforts to find an alternative right now, aesthetics are also a key consideration for my household so small and white are essential properties plus I know already that the KEF50W is good and I am confident that the KC62 can outperform my B&W ASW608s (at least when they switch themselves on!) so I’ll carry on watching and waiting but I’m certainly not going through the hassle of upgrading and then potentially returning the KC62s until this standby issue is sorted out.
Obviously from this thread I know that there is a workaround that some people are satisfied with (although some are not) but come on KEF - the LS50W and KC62 are supposed to be a match made in heaven but they can’t even coordinate power-on/off properly without a workaround?
I really hope that rumour of a firmware fix for the LS50W is true (and a fix on the LS50W side makes makes sense, someone in this thread actually suggested that quite a while ago). If such a fix really isn’t possible then I hope that a KC62 v2 can resolve the issue even if the resolution is as crude as having an extra 3-way switch on the back for on/off/auto which is what my B&Ws have. In fairness my B&Ws also sometimes drop into standby when my LS50Ws are still playing but at least I can set the switches to on rather than auto and that forces them to stay on (24/7 if I forget to turn them off).
I believe there are enough KC62 owners with this problem for a proper class action lawsuit. It is insane that KEF has not formally addressed this, the sub is useless in LFE for anything with silent or low volume passages such as jazz, classical and movies. I trusted KEF will do the correct thing and kept mine long enough that I can no longer return it. Needless to say, Im angry.
For me, the KC62 has filled out the LS50WII with a nice foundation resulting in a full range sound and a controlled, deep and pleasantly dry (as in: non blooming) bass that integrates well with the speakers.
Setting the subwoofer to manual mode, I have no problems at all waking the sub from sleep, even when playing music with modest bass at low volumes. So yes – I’m very happy with the combo.
Neil, did you buy your KC62 recently? Nice that it works w default settings. I need to raise the sub gain by 16 dB with the KEF app just to wake it up.
I would like to face the sub driver toward me, but I like to keep an eye on the orange LED on the side that shows the sub has gone back to Standby.
Hello,
Anyone observed differences between using cable connection to KC62 and kw1 adapter?
For me are big differences and I don’t know why. I am just changing between kw1 adapter and rca cable. no settings change in app, and the sub is much much better…
Sub is in LFE mode.
High frequency - 95
Low frequency - 55
Sub gain - 6
Thanks
Have you tried testing the two configurations with a UMIK-1 and REW? That might reveal differences in frequency response that account for what you are hearing.
Came on this thread for a general peek around as I was considering getting a KC62. I’m shocked how inept this wake-up problem is, and the lack of action in fixing it. Why the hell doesn’t it just come out of standby whenever the connected KEF main speakers do, and go into standby when they do? Why would you ever want the mains playing without the connected sub?? I never want any component, no matter what it is, with an auto-off which I can’t override. This one is clearly causing big issues to many users who have paid a considerable sum for the sub, the lack of fix puts me off the whole idea of the Kef Wireless too, if I’m honest.
