The issue of whether you should use a house curve or not is somewhat controversial. The new SVS EQ-1 DOES NOT allow for a house curve.
On the other hand, the AntiMode 8033 has a two position switch to allow for a boost down deep which qualifies as a house curve to me.
I think of a house curve the same way I think about tone controls. Some people wouldn't be caught dead using tone controls, others find them quite beneficial.
Compared to the 8033, you have at least as much flexibility to create a house curve with the SMS-1. That is one of the nice things about the SMS-1, you can adjust it to your liking.
