My JBL's sound good loud, and really good really loud. I love to crank it on the opening trumpets and when the THX trailer does its thing. While watching I keep my finger on the volume due to the neighbors.
I used to do that or use it artistically when a friend would pop over, oh this would be many years ago many before this site was even around.
Today I just rehearse the film/DVD or in some rare ones (laserdisc dts) and then leave the volume where it is not too loud or uncomfortable in the mid range to high.
I remember someone pointing out on Lansing Heritage site early this year, there is few high frequencies that might be too much to bare I forget which? I’d have to look though the posts and find the thread unless somewhere knows which frequency that is?
Certain lows sine wave really tax my ears and I’m sure it would bug the hell of out most others, when played at cretin SPL db level.
I’ve been looking into the dynamic EQ on the DCX2496 to find simple and yet easy level to control the flow of LCR where C tends to have different mix level, yet when L/R is too high its smears over C making it rather distant sounding.
Made a few good attempts last night with Star Wars IV [chough, chough!] during the opening there’s a nice drum beat in the centre and few other musical instruments playing if anyone cared to notice.
Generally I think as most of us get older we start to listen at lower level or safer level. Years many so moons ago, I’d be close to 100db on the control 5 and that is just TOO LOUD! The light-bulb fuse protection circuit would light up and my friends thought it looked trendy. LOL

Some of them are rated at 100db. But getting 105-112db on a less efficient 89db speaker is not that difficult with a good amp when you factor in room dynamics and multiple speakers (5-7). Emotiva makes very affordable amps that can drive 500 watts RMS for 89db speakers. But if you are really into listening to music/movies that peak well above 105, I agree speaker sensitivity should be a priority and anything under 95db is probably not going to be what you need, especially with a large room and even then you are going to need some dedicated amps that can drive some serious power to get to 120db cleanly and sustained. And at that point you should also be considering double drywall/green glue/ wall decoupling and lots of acoustical treatments
Well there is that crown SPL db calculator that does the trick quite well in determining the power needs VS desired listening level and distance from source the high the SPL and father away the more and more difficult it becomes, but not impossible just awkward if you don’t happen to have the speakers or amps.
