original earthquake drivers

[mkmk4]

my dad used to run a after hours way back in the day and part of his setup were 2 original earthquakes all ive heard about them is there sheer ability to in his words "**** **** up" hahah but then eventually they got stolen along with other equipment etc . so basically we still have 2 original 189E drivers.(the ones used in the original earthquake). i was wondering if i placed both drivers in a yorkville elite sw1000 cabinet if they could get damaged or not perform in the way my father and other texts ive read described them. i understand that the cabinet makes a big difference in the way the sub will sound that being said im a lot more worried about damage to the driver than producing bass that will bring my house down to a pile of rocks :P.

all that being said i am also interested in building the original cabinets. how much money would that take? how hard will that be im 18 and i have no experience in making a cabinet.

thanks for reading and let me know what you think

we need the numbers (model numbers) off the back of the speakers to answer your questions.

there are no model numbers on the back of the cabinet the only numbers are on a sticker and there different for each one ( i have 4) so im pretty sure they are not model numbers.

I believe the original earthquake driver was the same as the car audio magma 15, and used a pair of 15" slaps passive radiators in a 19" cube.

The only place I ever got them reasonable price was direct from earthquake. Any other place selling it was way higher in price. A quick google turned up this:
Earthquake SLAPS-15 (Symmetrically loaded Audio Passive System) 15" Passive Radiator

They will also work in a 21" cube sealed, with a bash 500 plate amp, but won't have quite the oomph as with the slaps.

i dont know if i misread your comment or not (i apologize if i did) but by earthquake i am talking about the Sensurround speakers used in the movie "earthquake"

ian posted a picture of the driver i am talking about on this topic
Sensurround horns - any information please?

it seems by looking at diagrams that the original earthquakes had a horn design and were fully enclosed while in the sw-1000 the cone is visible from the outside.

thanks for the reply

All I could find in some old papers (probably based on restoration job but no idea when, where, how and from who) and I'm not sure about the accuracy of the numbers;

Cerwin Vega 189E
Power = 400Watt (max?)
Re = 4,87 Ohm
Fs = 32,7Hz
Qes = 0,27
Qms = 3,67
Qts = 0,25
Vas = 238,1 Litre
BL = 24,70
Mms = 165 gram
Sd = 1080cm^2
Xmax = approx. 5mm

thanks for the info Djim

remove speaker and look for numbers on back of speaker, not cabinet.

i dont understand why that would be necessary both drivers are 18'' i would like to put the cerwin vega 189E driver into the cabinet i don't understand why i would need the model number for the driver in the sw-1000 cabinet :S explain?

because speakers are like car wheels,

you cant just throw a set of off road wheels on a race car.

you need to know what kind of car your wheels will work with.

or what kind of box your speaker will work in,

the numbers on the back of the speaker/s will help you/us know what box is best for your speakers, the speakers you have might not work, or may even be damaged in the Cerwin 189E box.
