What are you saying Beeman?? You agree with McStyvie when he says to never use double bass, but then you say you are
using double bass...??
Personally, I have measured my room with double bass on and off. It measures better with double bass on, and sounds much better to my ears. I'm gonna keep my double bass on, I don't care what anyone says!
I'm saying that Audyssey made recommendations to the AVR and the AVR set internal settings to the above and when checked against REW, room measurements showed the Audyssey recommendations to be the best choice of settings.
My apologies if I confused. I didn't see any confusion with what I quoted and then responded to. Maybe if I just quote this part?
LFE is tricky and you are more likely to muddy your bass and affect room modes and create nulls than you are to help it in any way. JMHO.
Yes, I find LFE and bass management to be tricky. I find that increasing Audyssey recommended crossover points, create conditions of reinforcement; both positive and negative.
I see dips develop and sympathetic nulls (harmonics) deepen because of the dips that develop due to increases in crossover settings.
Overall, I find LFE to be very sensitive or tricky if you will. I don't see crossing over at 40Hz, just above the limit of the mains (lower limit is 35Hz) and crossing over the center channel (lower limit is 59Hz) at 40Hz as doubling up the bass as the crossovers are being set at the extreme lower limits of each; the mains and the center channel. Basically, there's no bass at these crossover points to double up. Might be why I didn't see a conflict in my comment.
An aside, I do find the AVR amplifier can't handle the load when set in this fashion and as the action sound track increases in SPL, I can literally hear the capacitors drain as the speaker system volume drains to the back ground. Hence the "NEED" for a separate amplifier such as an Emotiva, XPA-5. Well, that's a next year item as that's another $900.00.
Again, sorry for the confusion as it's safe to say, in this case, clearly, one had to be in my head to understand what I was sharing.
