I did some fairly intense sims on the PK boxes over at the diyaudio thread, and the conclusion I came to was basically that they go a little louder and a LOT lower than boxes did in the 90s.Hey guys what's up? Another tech question, what kind of mid air SPL readings do you think they reach at these shows? Are we talking open air past 150dB barrier (not near the ports I mean in audience). If so that's pretty nuts... Thanks!
The funny thing is that DVDs trump all of these guys. I used to have a giant 10hz tapped horn in my bedroom, the thing was bigger than a refrigerator*, and once in a while a sound effect would cause the whole room to shake. There's some movie sound effects that go into the single digits. I've never seen this in a music track. I *thought* there was some six hertz bass on a Plastikman track called 'Ask Yourself', but it turned out to be a false positive, basically the filter I used to analyze the track wasn't set up right.Great post man, makes perfect sense! The stuff I really dig (DJ Magic Mike, Bass Mekanik, Techmaster PEB, Beat Dominator (mekanik's alias early on in 90's), Bass 305, basically all the "oldschool" Miami and Euro bass stuff, seems to be mostly pure sine tones (fundamentals as you just taught me) with not much harmonics. That's something I always loved was lack of harmonics in the bass. If there's a song with sine wave bass sweeps and drops I'm all over it, (must have equally great treble and mids to show off the highs). I'll have to check out these guys I might like them.
Sadly this. Also been in several mid 50's on music cars and every good EDM show I've been to is more impressive. Bassnectar at Spring Awakening last year from literally a football field away (it was in soldier field lol) hurt my ears during a transient peak, playing va va voom. The stupid koo koo clock noise was Loud, bass wasnt' super impressive at that distance, but you could hear it and feel it some, I know by 50 yards away you could begin to feel the grass moving and your chest had some pressure on it.. I also heard them indoors in bloomington a couple years ago and they were moving clothes inside the middle of the venue on the floor, using less than 1/4 their gear apparently.Also, what you say about experiencing that much bass in an open air venue is spot on. There is no way to compare it to anything else. I've built a car that did 162 on music from the passenger seat, with the doors open, it's a neat experience for sure, but it doesn't compare to loud bass in an open air venue. I think the open air bass wins because you don't have a vibrating car seat, door panels and a thin floorboard distracting you from the sound.
My TWO Pandora stations are DJ Magic Mike (for work) and Public Enemy (for truck and home)!Great post man, makes perfect sense!

I caught Nine Inch Nails a few weeks ago. They had an L'Acoustic line array set up. It's one of these newer array designs, the ones that mimic the Danley Synergy horn. (Basically the midranges and the compression drivers are mounted coaxially, like a Synergy horn.)
During the concert I noticed something I've *never* heard at a show: imaging.
It wasn't pinpoint, this definitely wasn't The Magic Bus, but it's the first time I've heard a big rig like that actually have something approaching stereo seperation. I'm guessing it's due to a couple things:
1) Coaxially mounting the midranges and the tweeters gets us a point source from about 300hz - 20khz
2) Line arrays still suck, but they've come a long way. With good shading we can lower the level of the edges so it doesn't create all of the horrendous comb filtering that's a staple of line arrays.
There was as an odd side effect though: It sounded polite! I think this was due to the absolutely insane number of elements, the entire system was basically loafing. It was a very odd sensation. I almost wish they had a way to crank up the distortion. The sensation was a lot like when I listened to some well known tracks on Jon's Magic Bus. The distortion is insanely low, but it's so low it almost feels like it might need to be added back.
I guess this is one of those things you probably get used to, but I'm not entirely sure I *want* my music to sound that clean. Again, this goes against the whole idea of hifi, but Nine Inch Nails playing at 120dB but sounding clear as an unmuddied lake was a bit odd.
