Loudest car in the planet using just a single DD9918Z and 4x Stetsom 7kd.

So is that 28,000 watts rms then? I would expect a high db measurement from that much wattage. Was the sub pressurizing a tiny cabin area like some of the guys do for spl or was it an actual vehicle with a cabin? Anyone can take an electronic piston and pressurize a small sealed container with the mic sealed tightly inside and get a high spl reading. It doesn't mean anything in the real world, but its impressive to the bassheads I guess. What type of vehicle was this in and how was the cabin set up?

that 180 was a test tone, an extreme vehicle isnt really designed to play music... you cant even sit in the cars, unless youre a dwarf, much less drive it

the jackhammer is unproven so far.

that's because the jackhammer can't do high SPL in a 'one note wonder' vehicle. if it can, then db draggers would use it as their favorite weapon.

I don't think it was designed for music too.....the moving mass is just too heavy to make good SQ. probably just made for show and boom.

Thanks for the link


Exactly, a solid cube made of concrete with a moving 26kw piston compressing the air at the "car's" favorite frequency. I'm not impressed by the spl as much as the fact that the car isn't even a vehicle anymore and therefore totally irrelevant to the equipment people in the real world use. Someone could also take a solid six inch thick cube of concrete with a single high power handling woofer sealed to one side, seal the microphone inside and beat that record, and I'm sure the woofer wouldn't cost 3000 dollars. The woofer wouldn't last but same concept nonetheless. Paint a few wheels and a fake windshield on the cube and call it a car.

if you look closely the Magnets are 'L" shaped and in two pieces, the part that is on the outside which is visible, is the part im not sure of, is part of the magnet.//the other part of the 'L' is definately a magnet because its right up to the coil.

i have a closer picture , but to lazy to upload.

it may only be there for structural support
