My Onkyo TX-SR875 I can if I want to but I never ever really use bass management. But spinning a bit of my dts demo disc APOLLO 13.
Set all channels (80Hz THX)
LFE.1 set at 120Hz with subwoofer output to +8.0db gain so LCRS with the LFE.1 is just a bit exciting on scenes like chapter 8, the NASA "Crawler".
Chapter 12, 35.13 the fuel pumps an extra rumble growls though the Saturn V.
There are control settings on the (audio adjust, page 7 tone control Onkyo) for LFE.1 settings
Dolby digital

Multich PCM
Dolby TrueHD
dts-HD master audio
DSD
0db
-10db

-oodb (off)
Did a quick print screen of each scene with fuel pumps one with LFE.1 added the other with LFE.1 at -oodb.
Same applies to chapter 13, when rocket engines fire up! Feels like an Earthquake!! The score and rest of Saturn V, rocket engines soon fade out smoothly to allowing LCR carry the bulk of low end if anyone can notice it?
Right I'll set AVR back to full range as I never use bass management I drive the one 18" sub for LFE.1 for digital discrete or if playing analog I need only press a setting on cinema processor that already has LCR low end routed to the same sub. And another set of smaller subs just for LCRS only.
All LCRS low end is handled though an basic 6ch audio mixer so I can trim the levels to equal match. The signal then routes to Harman Kardon AVP1a where I use the (80Hz THX) and let all the lows below 80Hz to lowest play though the extra subs. I use the Input level to suit the film for the room size and there's the extra (bass equalizer) my favorite.
The LFE.1 control is on the Behringer MDX4600 so I'm all within arms reach and I rather like left front row centre front row is also nice as is right and back row seats slams it chest on APOLLO 13.
