Curious as to why there's a big weight different with the Torus RM-15a and CS-15a,
and others like the 10a box style and 10aCS.
The 10a box is 42lbs and the CS is 36,I'd think the CS would be heavier.
Is the transformer smaller and more efficient,just curious.
I use these for my subs,mainly for protection as I had one sub direct to the wall(20a).
We had a small storm here in the spring and guess what,
the sub that was not connected to a Torus was toast all the rest(3)were fine.
these and everything is else are on dedicated lines.
Even before I had a computer tied in with a monster conditioner,same thing(toast).
Everything else tied to the Torus

.
Starting to ramble,but really curious about the weight difference,JAMES perhaps.
