Another excellent option is the nht x2 crossover which is much more flexible than the SMS, although it lacks the EQ.

So, which SPL sub do you have? With or without the auto EQ?

Re: Kal's comment on NHT X-2

I use an X-2 for high pass and an SMS for low pass and EQ

IMHO, this is a "best of all worlds" solution, but I thought maybe more complicated than the OP wanted to hear about.

PS the auto EQ on the SPLR subs leaves something to be desired. The SMS satisfies those desires.

Use the speaker level inputs, it lets the flavor of your main amp come through the subs amps and blend better with your main speakers.
