Any recommendations for a good 'demo' of my sub? I was going through that list in this forum, I have a handful of the "5 star" titles, I'm guessing any of them would be a good test?

Some interesting reading I just found. I'll have to check the differences between them as well, see if there's any output differences between the two settings.
Quote:
AVRs can have limitations when playing HDMI/MPCM audio that they don’t have with bitstream. One possible restriction is that the AVR cannot apply any surround processing to HDMI/MPCM such as Dolby Pro Logic IIx. Some people have run into bass management issues with HDMI/MPCM. One problem, reported by some users, was that their low frequency effects/bass channel was too low. The explanation for this was that the LFE channel is recoded 10 dB low. The expectation is that the receiver would boost this by 10 dB to give the LFE channel a higher dynamic range than the other channels. Some receivers apparently were not applying this 10 dB boost.

I would try the suggested tests first to see if it's indeed your AVR's preout voltage. If you connect the sub to the right speaker's preout and run a test tone you should see (hear) if your gain significant sub output, you said the phone's SPL meter was registering a solid 75dB output from your speakers, hopefully you'll get the same results with your sub. Demo'ing movie clips really isn't going to prove anything if you don't have significant output now, just my 2 cents. What do I know though????

Measure the right speaker's preout voltage with meter and also the sub's preout and see what you get, it's easier with a cable attached. Good luck

The sample size hasn't been large enough for me to say anythign definitive but adding the gain box immediately solved the issue every time except once. In that case he would do a AVR reset and it would work fine for a short period. He ended up sending it back IIRC.

I actually wanted to search through my (10,000?) emails and try to find some of the past conversations but there's just no time.

It makes me feel a little better knowing I'm not the only one to have this problem, and it seems to always be the people with Yammy receivers. Gives me hope that it's not from me setting things up incorrectly, and that there's an easy solution too!

@Kentucky , you can't really rely on a SPL meter phone app, I tried several of them since you brought up the problem you're having, they're ok for speakers but for subs you can have a 15-20dB difference in reading from the speakers to the subs. This is one of the better ones I've found, you should have a real SPL meter in your tool box though.

Brian it's a real treat for bass lovers, it often gets overlooked when asking for bass demo movies.

Is it just my BD copy of John Wick that the soundtrack is Dolby Digital only and not MA or THD?

Watched Midnight Special last night at -12 with friends over and had to turn the bass down 4dB to prevent looks of confusion from my guests. This movie really is a bass monster, but I felt it was almost too hot in parts with the dialogue mixed too low, making some scenes come across muffled. I'm rewatching select scenes right now at -5mv. Bass scenes are 3 minutes in, 22 minutes, 34, 61, 72, 95, and more with a lot of LFE throughout the music track. I agree with the other recommendations, and I'd say it's a must watch for bass films this year.

Iv seen it and didn't really care for it a whole lot. Not terrible I just really hated how the bass was sooo over done then the opposite with the dialogue. I remember going from barely being able to hear to insane bass. It was very dynamic in those regards but imo it's not the work of "quality dynamics".

I would like to see a few graphs of those specific bass scenes though.

I haven't seen Midnight Special yet but it sounds like I need to check it out. Sometimes hot bass works really well in a movie. For instance the bass in Mad Max matched the frenetic pace and scenes of the movie. But when it's crammed into scenes just to be there it doesn't make sense, even to bass freaks like us.

In Midnight Special, there is a scene right at the beginning where they are in a car driving down the interstate. There is a very low and loud bass rumble that is obviously just added for effect (i.e. not coming from anything happening on-screen). If you have your subs running hot, it will drown out the dialogue (ask me how I know! ). This same effect is repeated throughout the movie, and I like it. I think it adds to the tension.

Speaking of that early scene...when they exit the interstate, there is a low engine growl when the car accelerates up the off ramp that really kicks you in the chest (at least on my system).

I agree, as I loved Jeff Nichols last few films. Midnight Special is a solid Michael Shannon/Jeff Nichols movie, but I enjoyed Take Shelter and Shotgun Stories a lot more.

I played the first bass scene over a few times and lowered the trim a full 10dB to make it sound reasonable for what was happening on screen, but the car acceleration definitely calls for maximum bass.

My son is a big fan of Jeff Nichols. He loves the way he presents his films. Nichols won’t spoon-feed the audience with a bunch of hints or anything obvious. He lets the audience be just as confused or surprised as the characters all the way to the end of the film. Nichols also likes to employ extremely subtle scenes (like at the very end of Midnight Special). I won’t divulge what happened in the last seconds of the film, but I didn’t catch it on first viewing. I highly enjoyed Midnight Special and Take Shelter, and I'm very happy that my son recommended these films to me.

Music area: Magnepan 3.6, McIntosh MC2205 amp & C48 preamp, SVS SB13-Ultra, Oppo BDP 95, dbx 3BX, and assorted equipment.
Movie area: EMP Tek E5Bi (were rebadged to R5Bi), RBH/EMP Tek R55Ti, PSA S3000i, Denon X2000, Oppo BDP 83.

I guess I'm in the minority here but I just didn't care for midnight special. I mean it wasn't terrible but nothing to talk about about imo besides the random Monster bass scenes. Overall audio quality did not impress me, and neither did the movie. I watched once and doubt I'll ever watch again.

Jeff, the Blu Ray and DVD look exactly the same for John Wick. My guess is you grabbed the DVD. I have done this once with this movie too.
