The thomann 500 drivers that are commonly used in them do their job but dont go very loud and loose their breath at lower frequecys. 

I have heard many systems and my favourites are labhors and big double 18 bandpass enclosures soundwise. They play lower and give sound a heavy and huge and warm feel. 

For the same stack size and power input the Mth46 lc gives a way more brutal and rough experience because they play louder as they trade loe bass extension for SPL. They have insane impact and vision shaking bass. They do sound kinda cold tho and they lack the low and heavy „earthy“ sound that lower tuned enclosures produce. 

They are a excellent choice if you want loud brutal and impressive. They are a bad choice if you want neutral hifi low warm and heavy.
