You know mate that was one word on the tip of my tongue (bottoming out) makes my skin crawl it does.

Now I have been running Kenwood KRF-X9050D THX select AVR for 6 years now! But there are many approaches I take with the playback of films.
I can playback films at (0db) but that's only with the use separate amplification audio limiters for the three-screen fronts and equalizers for all the loudspeakers in the room.
It would be very rare for me to (bottom out) the two sub bass units that I'm running, one for what I call (sub bass extension) where all the fronts and surrounds low end passes though series of low pass filters and onto an audio mixer, (LFE.1) is also sent to the mixer and is amplified and played separately away from all other sub bass frequencies where they tend to over taxi the sub bass
and worse I have noticed degrading in the reproduction in the room.
So what type of films have you been playing for it to (bottom out) on?
Tell what type of films and I'll see if I have them and I'll run some tests, I also need to know which part in the film the problem first occurred at?
One other important note is, have you engaged the (THX bass manager) to on and worse I doubt you have read the owners manual thoroughly otherwise you wouldn't be bring this matter up. No matter its good that you have this might be a reminder for those who skip though the user manual at warp speed and miss some vital information.
Or worse the manufacture is
negligent in providing this information.
Before turn (THX bass manger) on! where it will produce a raw output of pink noise, and if your not careful with firstly turning down the sub bass units volume to minimum and with the setting of the fader set to (0db) grandly and very slowly turn the volume up on the sub bass unit while looking at the (SPL db level) make sure the metre is placed at the listening position and set for varies levels to start of with.
65dbc 75dbc and 85dbc. But before adjusting the level of the sub bass volume, set the level of the (THX bass manger) to around (-10db).
Still get back to me I'll be online all day and will go though this, one step at a time.
