Magico's Q sub 18
 
Has anyone heard this beast? 2 18 inch drivers in it and weighs 570 pounds. Each driver is enclosed with a 2 inch baffle. Indicates in the description that it produces 175 db pressurization, the same level of pressure as a Boeing taking off!

What's amazing is the cabinet. 1 % displacement of the enclosure at 175 db.

I believe this thing is priced at 36,000.

Would love to see/hear this!

Sounds believable:

85dB Beginning of hearing damage range, earplugs should be worn

100dB Normal average car or house stereo at maximum volume

110dB Car stereo with two 6 x 9” speakers and 100 watts

116dB Human body begins to perceive vibration from low frequencies

120dB Front row at a rock concert

125dB Drums, at the moment of striking

130dB Typical professional DJ system

127dB Tinnitus (ringing in the ears) begins. Permanent hearing loss

128dB Loudest human scream

130dB Marching band of 200 members

132dB Eardrum vibration noticeable

133dB Gunshot

135dB “Very loud” street car stereo. Bass only

140dB Threshold of pain, all frequencies

140dB Hearing protection required (definite long term damage)

140dB human throat and vocal cord resonance occurs

141dB Nausea felt after a few minutes

144dB Nose itches due to hair vibrations

145dB Vision blurs due to eyeball vibration

147dB Formula 1 race car full throttle drive bye

149dB Human lungs and breathing begins vibrating to the sound

150dB Loud rock concert, at speakers

150dB Sensation of being compressed as if underwater

152dB Vibration is painful and felt in joints

153dB Throat vibrating so hard it is impossible to swallow

154dB Compression will burst child’s balloon

155dB Experience cooling from excited air movement, up to 15 degree C perceived cooling

158dB Inside of a rock concert speaker bin with 5000 watts power

160dB Flashlight exhibits electromagnetic pulsing (dimming during tone)

163dB NHRA Top Fuel Dragsters- 5000 to 7000 horsepower

163dB Possible glass breaking level

164dB Internal sound pressure of a large jet turbine

165dB Jet airplane, Example: Boeing 727, at take off

170.75dB = 1 pound per square inch

172dB Fog is created, depending on the temperature, dew point and humidity

174dB Air begins to heat up due to compression

175dB Quarter dynamite stick, very close pressure may exceed 210 db.

177dB = 2 pound per square inch

180dB 1 pound TNT at 15 feet

One of the loudest sounds ever recorded was NASA's Saturn V rocket, which registered 204 decibels.

Even crazier! Where does The Who fit in, and Quest Field Seattle with one of the loudest stadiums in the country?

QWEST -- now known as CenturyLink field in Seattle was 137.6db -- Kansas City Chiefs fans' broke Seattle Seahawks' fans' record of having the loudest outdoor stadium by creating 142.2 decibels worth of noise at Arrowhead Stadium Monday night back in September 2014.

Best Sir,

Bob

It’s a crazy loud stadium, I didn’t realize we have been beat, will work on changing that!

I live in the past on many things, maybe don’t want to let go, dunno -

Interesting. Where was that level measured?

I was in the press area for Skylab which was aboard the most powerful Saturn V ever. Unforgettable.

I'll help you beat the record. Love going to Seahawks games!

**The launch of a Saturn V rocket, for example, produces around 220 decibels, which ignites grass a mile away with the sound alone. The launch pad has to dump 300,000 gallons of water in 41 seconds below the rocket for absorption or the reflected sound waves would rip the rocket apart.

**The water suppression system reduces the acoustic sound level to approximately 142 dB.

Best Sirs & apologize for varying off OP topic,

Bob
