Subs to atmos channels

Evening!

I have extra subs, but this install requires quite a bit of effort. Is it worth adding a subwoofer to atmos speakers allowing them to be completely full range. Any one try this?

Thanks!

When a smaller Atmos speaker is present using a high crossover, the lower frequencies will be sent to any subwoofers connected to the sub pre outs of a given AVP/AVR along with the signals in the LFE channel.

If one is connecting multiple subwoofers to an AVP/AVR using speaker terminals or pre outs to Line In ports and setting all channels in the AVP/AVR to Large/Full Band, the subwoofers had better be equipped with HPF or the full range signal will be passed along to any speaker connected through it and lesser speakers will be damaged.

Yes, that is a total waste of time and won't work. The crossover will direct the bass of you ceiling speakers to the sub. Your idea is a total non starter.

Wrong, if the sub supports speaker terminals it becomes the high pass filter so you simply set them to large.
You are incorrect if my approach is used.

You have no clue. Once you set a speaker to small, all the bass that would have one to that speaker if you had set to large goes to the sub. At the frequencies we are talking about are non directional. So you are talking absolute nonsense.

Many subwoofers with speaker terminal connections will not feature HPF functionality and will simply pass the “Full Band signal on to the speakers connected to it.

Nobody in their right mind is putting together Atmos tracks with very low frequencies in anything but the LFE channel and some low frequencies in the Front channels for use in systems with no subwoofers.

Even when setting ALL speakers to Large/Full Band and connecting numerous subwoofers with HPF functionality to ALL of the speakers in a given system, Atmos tracks will have the lowest frequencies in the LFE channel. With no subwoofer available, the Front channels will handle low bass duty.

Only those with robust amps and very capable speakers should ever consider setting speakers to Large/Full Band when playing any of today’s multichannel movie and music tracks at considerable volume.

For more localized bass NOT in the LFE channel, some new Denon/Marantz units have “Directional” mode support for up to four subwoofers. Using four subwoofers, each would handle bass below the crossover of those speakers in their quarter of the room and ALL of them would be fed low frequencies in the LFE channel.

You already have subs in use ? Which ones and how connected? By adding to atmos speakers, you want to install subs in ceiling and run them off same signal or what? Specifying your setup might help.

Your post does not include enough details. Are you suggesting tapping off of the ATMOS speaker wires and running that in parallel to the subwoofer speaker terminal input?

Not recommended. You would have to change your ATMOS speaker setting on the AVR from "small" to "large" otherwise the bass gets filtered out. If you do that, you are no longer hi-passing the signal to the ATMOS speaker. It is then getting a full signal which defeats the point of bass management. In addition, the ATMOS channel receives very little bass. It's only an effects channel. Your subwoofer would likely be outputting barely any sound. Your speaker channels also do not receive any LFE (low frequency effects) signals. Those only go to the subwoofer channel. The whole idea with multi-subwoofer setups is to send the same signal to all subs and smooth out the response in room. Tapping into an ATMOS channel serves no purpose.

There are wireless options for subwoofers, like the transmitter SVS sells.
