I use it for 2 years
phase switch and low cut filters handy
the frequency range of tops is just too
with experience (and wallet) I take rather a dbx DriveRack ds or something like that but for the beginning it nikel
I use it now for 6 months time on active filter diy bi-amplified speakers.
I also dcx 2496.
This filter is very easy to use! but he has a big drawback: when using no sub output, low section falls to the low cut (30Hz). I think its a shame we can not choose or cut (thanks to Knob frequency section sub) section serious.
this product remains a good value for money.
