Here is one of those parties those rave parties that play into the early hours of AM! Not 11 pm and that it! this bugger is playing a few miles from me. you’d think it was coming from across the road with some part of the mid range, thou slightly muffled and it would be coming directly across the road, when in fact, the word is after, walking around for 2 ½ hours out its point of origin, the source?

Well its not that simple unless you have 100% idea where the outside event is? Otherwise it amounts to (a needle in haystack) its some 2 miles away and there are lots of roads that have dips and peaks valleys and hills and I’m frigging buggered after walking around, because I’m sure its an illegal event, I mean playing at the early hours now, or it could be legal outside event?

I’ve taken a frequency waterfall graph to show roughly the bass range that is travelling, the long distance from what must be a 30 to 40KW sound system who knows maybe more, I know when I was walking around I was in spot where I heard a tone between 30 and 50Hz and it sound liked thunder.

ECM8000 stuck outside the window.

Even outdoors 2 miles is a little hard to swallow :). And just saying this is the case. What about the people living closer than a 2 mile radius? I don't know where he lives but if that was the case around me people would be gathering at the police station calling for the source to be shut down.

168dB at the source for the higher freqs (ultra powerful sirens) free air radiation, you will be able to hear it clearly even at approx 5 miles. Lower freqs would not suffer as much attenuation and the waves will wrap round corners etc....

Kindly note, its free air radiation, not car audio. :o

I'm surprised that you didn't know Danley brought the Matterhorn over to UK since last week for a show. :D

I feel a little sorry for the poor buggers that have to live within 1000 yards or so from where that was playing last night. Damn some of those lows notes, where really travailing. Whilst giving up and walking back home, I stopped for a moment to (sit down) on bench and spoke to person sat next me, who was German, and I said “can you hear that music?” he replied “yes where’s it coming from?” LOL

I sat and we talked as little traffic noise passed in-front of us that (masked) some portions of muffled mid range. Once it was quite we can (both) hear this frigging rave music that seemed to be coming from a possible few house’s across the road.

I said thanks for talking and I was heading off up hill, he said he’s got to go in that direction as he lives near. Once at the top of the hill the level of the sound got slightly louder thou on the soft side, it only changed in tone, the bass was (deep) and you would swear it was coming from flat? LOL

Walking down the road I noticed a couple on the opposite side I, called over quietly can you hear that music and they said “yes where’s it coming from” LOL no could guess apart from guessing, I think its coming from that direction!

Anyway for large outdoors PA system comprising of dozens of sub bass cabs mid-bass cabs mid range and high frequency range, how far can it travel until its not audible by the ear, 4 miles 6 miles 8 miles 10 miles?

Also wavelengths I know each have there own wavelength but when amplified and stacked up with clusters of the same, how far can it reach, is there a Guinness book of records, because last nights one should be added to the book.

As for the fuzz being called in I wouldn’t know? I remember a road that looked like the Abyss it didn’t have one single street light apart from a single light. I walked around the area and the sound was reflecting of houses and rooftops and god knows if the residents got any sleep because it was far louder in one spot, where a driveway curves upwards and the (sound) made you think it was coming from someone’s back garden.

Talking about taking the piss at 11:30pm at night! While walking down the naffest English country road lane, that almost seemed endless, I managed to get a glimpse of the lights thou it was pitch black in front and slightly hazy with soft pillow of light, that looked like it was 2 miles and there was no way I could see clearly over the field.

I guess that drives you nuts on the weekends.:D

Maybe you should stick the microphone outside and record a few graphs. Is it audible inside the home?

For a moment I thought it that aircraft was an SR-71 Blackbird? I paused the video and thenn took another guess, was that the now retired F-14 Tomcat flying overhead, (sonic booms) nice find.

:eek:Bugger that one! I focused on the left hand corner of the screen on the second viewing of that outdoors explosion and the earth the dirt just leaped in the air and partly blow backwards, wow, wouldn’t what to be near to that because the sound wave will feel unpleasant if that hit you in the chest!:(

Danley yeah sure I’ve seen the name. They wouldn’t be stacking a Danley PA rig outdoors near and between Bournemouth and Kingson because this buggered travelled. LOL

I was doing a new Google search under Danley Matterhorn in the UK and found this, only this is in the U.S.A. and its been banned from NSCA demo LOL.

"sonic boom generators to critical listening mastering studios, high-end home theatre, and houses of worship around the world."

Houses of worship, yeah maybe I was hearing a late night church festival last night, “praise the lord, can you feel the power of the lord.”:D

I thought I’ve seen this video before not sure if it was last year or the year before? Still its an insane sub! Didn’t they use to drown out crazy whacko Bin from those caves?

Oh, yeah just drive down the road with that thing chugging away while busting in windows! LOL:D

The Matterhorn - Worlds Largest Subwoofer

The Matterhorn has been discussed here before occassionally and its pretty old news, sometimes against the Thigpen and sometimes against the Royal Device. In the PSW forums, some car-sub player would pit it against the dB drag cars and claim the cars are louder. LOL! :D

But Tom Danley has definitely been around very long in the audio world, I'd believe longer than any of the subwoofer / audio brands mentioned in this board, except for JBL, Altec, EV. :)

If you'd like to upgrade your 2242H based direct radiating subs and go for Danley, can try the TH-112. Its the cheapest (usd 1.7k) and goes quite loud, extend decently and sounds very very good all the way till 120Hz easily after EQ. For this cheap price you can get a pair even. Get some good cabs on top
like from Stage Accompany, modify a bit (eg stuffing) and you will have a very good pair of mains for music/HT, so good that it will make mainstream audiophile-type stuff of the same price like Monitor Audio Platinum look very very embarassing indeed (5.5k pounds for a PL300 with a usd90 Fountek tweeter, 2.5k pounds for a 15" 1kW sealed + DSP? LOL!). :o

BTW, those big stacks of speakers you see in large shows are called line arrays.

I’ll stick with what I have for the time being unless opportunity knocks and I have the means to buying something like the Danley at knock down price.

The line arrays, yes of course, I’ve seen JBL line array on the professional sites page, I don’t think my neighbours would like that rattling plaster out of the ceiling and raining down on them. LOL

20Hz at best is low enough and life doesn’t really evolve around high ranges of infrasonic or even sub bass on a daily basis, well maybe it’s an option.

So just how much does the Danley TH-112 go for and don’t say £1000.00 pounds let me hear £500.00 pounds.:D

500 pounds is a bit difficult even if it is used. I'm not sure if there's a distributor over in the UK. The good thing is that DSL is setup for very good shipping rates (even better than SVS).

Here's the MSRP.

I just heard a Mackie SWA1801 last night in an open venue (no reflections in bass freq), heh heh.... I'm beginning to appreciate my sub more even though I only have PEQ in my room. Absolutely different league.
