From there the Left Mythos is connected to a splitter to connect the LFE on the Left and Right Mythos. Then the RCA to the Left SVS sub is split to connect to the LFE on the Left and Right SVS. I have the Mythos set to large and sub enabled.
I'm not sure if there would be a benefit to removing the splitting going into the yamaha and having the Mythos ST connect into the rear sub input. It sounds pretty good now but i'm sure there are still settings I should adjust.
The mythos ST only has a LFE input and then speaker inputs. The SVS does have additional inputs but I don't think my Yamaha has an output for them.
Sorry I'm having trouble picturing your connection, sounds like your basically just splitting the the LFE signal into the ST's which of course will work.
Even though the inputs on the speakers say LFE it's actually a low level input to the amp for the woofer, while yes it was designed to be used a Sub/LFE input, it can also be a simple low level connection too, remember LFE isn't simply low frequency sounds, it is it's own discrete Low Frequency Channel, there are still other Low Frequency sounds that are coming from the the front channels.
It will still make a difference with your Large/Small & Crossover settings.
If you run just speaker wire to the ST's the Sub's/Powered Woofers will still work, again just not for LFE content.
Check your settings, I'd start with just running speaker wire to the ST's set your Fronts to Small with a 40hz crossover setting, this will send everything from 40hz and up to your Fronts, and everything below to the Subs.
Set your Subs to whatever best matches their actual location, this setting may effect Sub Phase when using two Subs.
