In what subs were the LMS coils originally used?
I was thinking they would work in the RL-s motor but the OD is a bit too much. They are pretty much the same dimensions other than that. Would support an incredibly massive stroke of 4 inches plus, so deep parts are a must.
 
holy smokes typical configuration is about450 grams.. talk about a huge motor..
They weigh 208g as aluminum, just imagine if they were copper! The standard RL-s quad stack depth would work (two .75" slugs and two 1" slugs) but the gap needs to be just slightly bigger. Same WW as the RL-s coil, though.

if you get some 3" by 80-90mm flat wound coils lmk. im gonna start putting some stuff together soon.. i'm also looking for some rubber surrounds.. high excursion..

 
it looks like a 2 layer then 4 layer on the ends? or its is 4 layer and 8 layer ends? BTW how much do the other 4 layer 74mm coils weight? they flat wound alum? what gauge? im interested..

LMS coils are 4 layers very thick gauge, gotta be 18-20. The other coils are round aluminum 24 gauge bifilar winding so inductance is lower. Really nice coils.
Hit me via PM for the other stuff so we can keep the for sale threads clean, thanks.

2x 4 ohm coils can be wired parallel to 2 ohms or series to 8 ohms. There's many amps with 2 ohm power you can use.

Not a term, a description. When it clips, it sends a distorted signal (current) through. A square wave contains more energy than a sine wave and...
