I’ve had a pair of Kef Ci130CR speakers running from a Connect Amp for a while now. They pair up brilliantly.
I’d just added a pair of Kef Ci130QR speakers to a second Connect Amp, and it’s problematic.
Randomly above 50% volume, and always above 80% the amp cuts out.
- The CR speakers are 8ohm with a recommended amp of 10-80W
- The QR ones are 6ohm with a recommended amp of 10-50W
I guess the issue is that the Connect Amp is cutting out as at higher volumes it does not have enough power to push the QR speakers. Is that accurate?
Any workarounds or do I need to source a new, higher output, amp (I do have a spare Connect lying around!).
Thanks.
Cheers,
Ferg

Connect Amp with Kef Ci130QR ceiling speakers?

Yes, and for more insights/tips see: https://sonos.custhelp.com/app/answers/detail/a_id/2934/kw/flashing%20orange%20light
There is a good idea there about testing one speaker at a time after disconnecting the other.

At 50-80% it should not cut out with these speakers. Is the Connect Amp kept in a well ventilated place? After how much time does it cut out?

Why am I seeing 8 ohms for these on the KEF sites? If that is the case, all the more reason the amp should not cut out. And at a quoted 87dB, the sensitivity is reasonably high too.

Maybe you can change the speakers to the model that works fine. Also, check the integrity of the wire connections at both ends.
All good ideas. However, the speakers are installed ceiling ones and removing the working ones is a little difficult and needs a ladder :-)
I've emailed Kef support to ask about what the actual nominal impedance of these speakers really is.
I've checked all the speaker cable and it is OK.
BTW I never answered your questions about ventilation. The Connect amp is on an open shelf with plenty of air around.
I noticed yesterday that when the sound fails then the light is a blinking orange one. That's correct for this error, right?

I checked everything and above 80% the speakers still cut out. Kef Support say that the nominal impedance is 8 ohms not 6. However, they also say that regardless of the impedance the speakers should be fine and it's a popular combination.
I had a garden party on Saturday and the speakers are still fairly loud. So I think I'll just live with it! Thanks for your help!
