Hi Chet and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, bear with us; re-confirm and post back with the complete model number of the "...SpeakerCraft Speer sitter..." Additionally, please describe how the AVR-S920W is connected to this SpeakerCraft product(s).
If it is an independent speaker system, then it would preferably wired likewise as FRONT R & L speakers. However, it may need a switcher box.
Would you be comfortable with this approach ?
The AVR-S920w does not have audio output that can work with "...audio cable (Red) in from the SpeakerCraft and a HDMI ...".
This model has only audio output from its SUBWOOFER PREOUT and the speaker terminals.
The SUBWOOFER PREOUT can not be used since its output would only be the BASS / low frequency.
Which leaves us no choice but to attempt as posted above, "...wired likewise as FRONT R & L speakers..."
First, any model number of the SpeakerCraft?
How do you turn it on/off? ...once turned on, is there a thump and/or humming sound when the "...audio cable (Red) in from the SpeakerCraft ..." is touched?
What exactly please is this "...audio cable (Red)..."? ...does it have a connector? ...or a plug?
RCA plug? Or better yet, a clear picture please; click HERE.
How is the SpeakerCraft Speaker System turned on?
The SpeakerCraft bass power 250 is a MONO amplifier primarily for use with subwoofers.
The SpeakerCraft - S4VC Multiroom Speaker Selector IS a switcher box.
Please re-confirm that the other connection is a "...HDMI coming from the wall..."
Let's step back and check / review the basics.
Have you tried the ".once turned on, is there a thump and/or humming sound when the "...audio cable (Red) in from the SpeakerCraft ..." is touched?"
And there is a thump / humming sound?
If yes, connect this "... red audio plug..." to the DDenon's PRE OUT SUBWOOFER 1.
Reduce the Denon's volume and set it to an FM music station. Test if there would be sound from the Denon's own speakers and from the SpeakerCraft subwoofer/speaker.
If none from the SpeakerCraft subwoofer/speaker., then please check/ensure that the Denon's Subwoofer setting is set to On and Subwoofer Mode is set for "LEF+Main". Also verify that all other speakers of the Denon are set to "Small".
Kindly consider / perform a RESET of the Denon.
Sorry; "...All do..." RESET done?
Yes please, when able.
Incidentally, the User's Manual shows a full reset back to factory settings on p. 239.
