Guys, thanks for the tips about the great LFE in U-571 and War of the Worlds. As it happened I already owned the 1080P BD quality file of U-571 in my Kaleidescape library. The file also contains the film's DTS-HD MA 5.1 soundtrack. I am downloading it to my Kscape Strato now and will watch it again soon. Also just ordered the War of the Worlds BD from Amazon, mostly because, in the immortal words of Gilda Radner's Roseanne Roseannadanna, "It was rill chip." I got it for less than 10 bucks. That's what I call a bargain! Looking forward to seeing both of these films again. Thanks again for the heads up.

HT setup: Sony 75XBR X940D UHD HDR TV; Kaleidescape Strato Movie Server 6 TB; Yamaha RX-A3060 AV receiver; Sonamp 2-1 2channel 100W power amp; Crestron Control System; 2 Rythmik FV18 subwoofers, 6 Hsu HB-1 Bookshelf speakers, 1 Hsu HC-1 Center speaker, 4 Focal ICW8 in-ceiling Atmos speakers; Oppo UDP-203 4K HDR BD player; Mac Mini HTPC.

The World War Z grenade scene is one of the coolest LFE experiences I've had. It's very short but, great.

I've been picking up more films with great LFE thanks to tips I received both here and in the JTR thread. Just preordered the Dredd UHD HDR Atmos disk from Amazon. It is to ship on June 6th. In addition to great audio, it's a fun story. I loved the evil, scarfaced Lena Heady.

My go to demo HT scene is war horse chapter 21. You liked Hacksaw Ridge? Very similar but even more impact...no joke.

You should use the spl meter tool in REW set to Z weighted, fast response and use the spl logger... it will let you see the loudest peaks in overall spl (including under 30Hz stuff) and also average levels.

Fast response updates 8 times per second so it can better capture loud transients that slow response will just average once per second.

Z weighted means unweighted and so it won't roll off the extreme ends of bass and treble... just don't use it for setting trims/levels as c, slow is recommended for that.

I have a feeling you're listening much louder than you previous post indicates, considering how much tactile response you're getting. The UMIK-1 is a better spl meter than actual ones that also measures everything else in REW.

I think i may be listening at too high a level too. Will check it out with REW.

I was going to make a vid clip of rew with some music but the spl box wouldnt go over 100db and kept giving flashing red warnings lol. I was using the RTA box with distortion, levels, spl, etc... but just didnt get it figured out...so scrapped that idea.

I will use the REW SPL meter as you advise and see what it tells me. My son in law and I spent a couple of hours this afternoon fine tuning my FV18s and we agree that their levels are now about right. I still get a tactile feel from deep and loud LFE, though. I think that is the result of my subs nearfield location. The driver of each is only about 7 feet from my MLP. With two 18 inch drivers putting out simultaneously being able to feel it is not necessarily caused by very loud listening levels. Anyway, I will follow your admirably clear instructions for using the REW SPL meter and find out.

a great audio demo would be this one:

Funny, I was just listening to a track from techmaster p.e.b. and my daughter just walked into my room and said "dad, cool song but can you turn that down? Its shaking the whole house." That's with just my
LVX12. Love my Rythmik

I couldn't imagine what dual 18's would do...

This and the FV18 discussion got me wondering... Could large subwoofers actually degrade a home's structure over time ? It might be wise to build a home from something other than wood framing, like steel or ICF's, before going too subwoofer crazy.

I have discovered that in a dual purpose space, there should be little danger of driving subs so hard that they do structural damage. In experimenting with my FV18s playing the notorious opening scene of Edge of Tomorrow I discovered that its LFE makes doors, windows, and loose objects rattle unpleasantly, despite the FV18s having no trouble accurately reproducing it. I understand that scene digs down to 10Hz. If that's true, it's no wonder it sets off sympathetic vibrations. I suspect the only way I could get even my FV18s to give me a pleasant sounding result from the scene would be to place them in a sealed and sound treated dedicated home theater room. Alas, most of us all learned a long time ago getting the best low frequency in our home theater inevitably requires some compromises.

I couldn't imagine what dual 18's would do...
I rented a couple of noisy effects movies this weekend (wife's on a trip, I can make as much noise as I want!), Edge of Tomorrow and Deepwater Horizon. The opening to EOT is interesting, and my pair of LVX12s just went for it, shaking everything in the room (including me), the room itself, and probably the rest of the house as well. And this at -10dB on the AVR. No hint of the LVX12s even working hard. Plenty of interesting LFE in EOT also. DH has less bass then I would have thought, but it's really active on the surround channels, really immerses one in an oil rig disaster.

And for both, I couldn't imagine needing or wanting more bass than what I got from the LVX12s. The sound I get exceeds all but a couple of our local theaters. My wife actually prefers our sound over the local theaters.

I can't image what dual 18s would be like either. Given that I'm maxing out at -10dB I don't really see any point -- a bigger sub would just be wasted on me and my small (7 x 4.2 x 2.5 m) sealed room. Makes me thankful for closed plan (as opposed to open planed) architecture.

When running sweeps in REW, I've noticed that when I hit about 95dB things start shaking significantly. It is all but absent at 90dB and non-existent at 85dB or less.

100dB and 105dB makes the whole 2nd floor shake. I know because I went to the opposite side of the house, still on 2nd floor, while running those compression sweeps. And my sub doesn't really do under 20Hz stuff.

It's all good and well though, because I listen typically in the 80dB to 85dB peaks for sub. I know some say you can't get listening fatigue from too much bass but I can easily once I go even 2.5 to 5dB past my usual levels.

I watched Deepwater Horizon again a couple of nights ago. Despite its awesome LFE, it didn't setoff sympathetic vibrations in my family room the way the LFE in the crazy opening scene of Edge of Tomorrow always does. I played both at -10dB below reference.

I can't image what dual 18s would be like either. Given that I'm maxing out at -10dB I don't really see any point -- a bigger sub would just be wasted on me and my small (7 x 4.2 x 2.5 m) sealed room. Makes me thankful for closed plan (as opposed to open planed) architecture.
I watched Deepwater Horizon again a couple of nights ago. Despite its awesome LFE, it didn't setoff sympathetic vibrations in my family room the way the LFE in the crazy opening scene of Edge of Tomorrow always does. I played both at -10dB below reference.
YPAO doesn't calibrate absolute spl to 0MV like Audyssey does. So, instead it typically sets the front left speaker to 0.0dB trim and then matches all other speakers to that level, whatever it may be. The only time it adjusts the front left speaker trim is if the sub or any speaker needs more than a 10dB increase or decrease relative to the front left speaker. Like if one speaker is much closer and/sensitive than the others in room, relative to mlp.

In a nutshell, I believe Audyssey is the only system that does make sure 0MV is reference... not YPAO, MCACC, Dirac Live, ARC, etc. That means if you speakers are very efficient and near field you will reach reference level well before 0MV and if they are very inefficient and far from mlp you will need to go past 0MV to hit reference.

For example, I know my center channel hits 75dB with internal test tones with -5.0dB trim at MLP, but YPAO sets it at -1.0dB. So, I know reference level is occurring about at -4MV.

Bottom line is what MV you listen at only matters for Audyssey users or those who manually calibrate levels so that you get 75dB with 0MV and -30dBFS signal for speakers with bandwidth limited pink noise and spl meter set to c, slow.

I am no expert on audyssey but at 0mv I am well past 75db....more like 100db with just front 2...with subs on closer to 115-118.

Gwsat is using YPAO, but I'm using an older Denon AVR-X4000, so Audyssey MultEQ XT32, Audyssey Sub EQ HT, and Audyssey LFC. Calibrates the two subs independently so they are nicely in phase at the main listening position.

Yeah, 75dB with -30dBFS signal. It would be 105dB with 0dBFS signal for speakers.

Add 10dB for LFE channel... so 75dB with -40dBFS signal and 115dB with 0dBFS signal.

And for subs you must also add 5dB or so for bass management plus whatever dB hot via sw trim and or dynamic EQ/YPAO volume, etc.

^That last bit is about actual listening levels not calibrating trims.

Probably the best way to evaluate actual peak listening levels is SPL meter or logger in REW.

You should place those mains slightly in front of the subs.

Love those triple round ports. I prefer the look of round over slot port.

Hi gwsat,

Looking at the pics posted of your new sub set up. You mains, especially the left and right channels are getting early reflections off the sides of your new subs. If you can, try moving the L&R Main speakers forward so they are on the same front plane as the Subs. This will eliminate any reflected sound issues you have now.

The Subs look gigantic! But to me at least, they look good. I know you are enjoying your new Subs!!!! Have fun Capt.

Regards,
Adamg
