Its just the way it sounds.

I think it has something to do with low pass filter and its rolloff,bryston has 24db octave filter,where oppo must have something like 12db,which would be very unusual for low freq.
Probably it has 18db and that is the culprit!
From my experience,difference between 18db and 24db can be huge.

It can take up to 4vrms in bypass mode.
Never heard of an 18dB slope. The OPPO is 12dB.

I had some old "Infinite Slope" brand speakers years ago that had 100+dB-per-octave crossovers. Loved the sound of the speakers - but really can't say whether the crossover slope did anything for them. I suspect that it did, since the phase distortion problem that is inherent in crossovers was mitigated to a great degree. But now we have DSPs that can compensate for that to some degree, and there are both advantages and disadvantages to both conventional and "hard-wall" crossovers. The Audio Theory forum ought to have a good discussion about this.

Display: Panasonic P60UT50 (Plasma)
Speakers: (4) Monitor Audio Silver 9i (Front and Surround), (1) Monitor Audio Silver 12i (Center), (4) Monitor Audio Silver 4i (Rear and Wide), (2) Aperion Audio Bravus II 8d (Subwoofers)
Receiver: Pioneer Elite SC-87 AVR (9.2)

I couldnt find what slope is on oppo,but when its true that it has 12db,i am sure this is the problem i am experiencing.
Why would they use 12db slope,is beyond me.In low pass slope should be steeper,am i right?
In car audio nobody ever would use
12db for low fq.I had amps and preamps in my car,where i was able to set low pass slope,always ended up with 24db and the difference was exactly i am experiencing right now,with oppo player.

Maybe it can be 'fixed' in future with software update?Probably more people must demand it,which i really doubt.

My sub has the option of a 12dB or 24dB slope. I use 12dB, but not in a normal way. Sounds good in MY room. You just have to play with it to see what sounds good in YOUR room.
