Default A bit off the DIY theme, but the best bass I ever heard was...

The earthquake of February 28, 2001 at about 11 in the morning. I was out on my front porch enjoying the scenery when it struck. It was 6.8 on the scale and centred near Olympia Washington, about 3 hours south of here. Now I know there are a lot of people on this forum who were closer than me but I got to watch the water in my pond slop back and forth as well as the trees swing on a calm day. It was my first real earthquake.

By far the thing that sticks out more than anything other (because there was no damage to my place) was the RUMBLE. I mean gut wrenching, leg weakening, equilibrium destroying bass! Something no audio system would be capable of.

Other than earthquakes, ('cause I've used that one) what are other examples of high SPL, low frequency experiences?

Anyone?

What about sitting inside one of those stupid vehicles made for SPL competitions, during the demo... 173.3 dB SPL would probably cause permenant brain damage, which is probably why people continue to do those competitions.'

I lived through dozens of earthquakes, the worst of which lasted an ENTIRE 60 seconds. Don't remember what it rated on the scale, but that was a scary 60 seconds of my life!
And yes, it produced some mean rumble.

Aside from that, thunder produces some crazy rumble, especially when it sort of tapers off, then everything shakes.

The other thing, and I'm sure not too many have experienced this one, is explosions. Several that stick out in my mind (lived in a warzone for several years). A 500kg bomb dropped from a plane, heard from fairly far. Shook the house (we thought it was an earthquake).
Two moderate cannon shells exploding close to where I was at. One exploded about 500 or so feet away, threw me on the ground (i was running at the time). The other, i was sitting down, was probably the loudest and lowest to high frequency i've heard, and that one was less than 300 feet away. EVERYTHING shook, my insides turned upside down. I was young at the time, so no hi-fi, but i'm sure if i heard it at this time i would think about the crazy un-distorted, ear piercing, clear as day bass

Default 10 second thunder thump?

I once heard thunder early in the mornign and i woke up from it. The sond lasted extremely long, like mabey 10 seconds. I have never heard it like that before. Im still puzzled how all that sound energy managed to last that long. It was a extremely phasy sound that was moving away (like the dopler effect when a car passes you and first the sounds are pitched up and when it passes you its pitched down.) The sound lost more higer harmonics the longer is lasted. There are no mountains where i live so thats not it.
Ive heard plenty of lightning and thunder but never like this
There were several of these longer eruptions.
Ive heard of temp. and humidity effecting these things. Its posible that sound passes over some housing or whatever and to land behind it. Could it be the sound was launched almost verticaly and came down almost verticaly ? Thus creating an time delay phenomenon?

Default subwoofer vs earthquake

I have experienced the 1980's Fullerton 6.1 earthquake and I can say that it feels quite similar to what a good subwoofer can simulate except that a real earthquake feels like 10 to 100 times scarier.

I have used (2) Cylindrical shape HSU subwoofer and if it's turn up loud, it can shake the building structure on the other side of the house. I'm not trying to promote HSU sub but that's what I have experienced.

Growing up in "The Motor City" (Detroit) Engines come to mind. Outside of nature's bass "movements", I'd have to say that there were/are several that have always impressed Me.

The first was the sound of an unlimited hydroplane (running a supercharged Rolls-Allison v12 out of 4" open pipes!) going "Full Tilt" (100mph+) from about 25' , was awe inspiring!

Almost the same engine ^^^ in a P51D on a low pass.

Two 5000+hp "Funny cars launching 8'-10' away.....WOW!

A F15 going from 0mph (on the runway infront of Me) to 40,000' in under 90seconds. Then doing a >mach high speed pass! (Gave me a huge lump in My throat.)

The Blue Angels "Doing Their Thing".

Several pounds of dynamite detonated underground! I was (too) near a quarry when they were dynamiting the walls. With the explosion completely encased in rock there was hardly any higher frequency sound at first but the low end had a visceral impact unlike anything else I've experienced. I could literally feel my guts vibrate.

The higher end sounds created when the wall section hit the bottom of the quarry were interesting also. Surprisingly like glass breaking, and we're talking about rocks weighing thousands of pounds.

Dude, were you traumatized by an SPL comp car as a child? What's your big hang up with them? You like subs, we like subs. Some of us are more extreme than others. Perhaps you don't understand all of the work that actually goes into making such a vechicle. Or all the planning that takes place.

Yeah, it's a little insane, but for you to call it stupid just proves your ignorance.

I think I was in Lake Placid, not sure, but anyhow, F16s flying overhead and hitting their afterburners....hitting the speed of sound! My Shiva! yehaw!


I think SPL comps are stupid too Honestly though, if a dude wins a competition using Pioneer subs, suddenly Pioneer is the greatest and when I tell them about Adire Shiva, Tempest, etc. they say, "I want a real brand." That ****es me off. Watch out I'm steaming and at the controls of my 53L Shiva.
