This weekend I'll be placing my order for SVS & Samson amp. I'd like to X-over lower than the 100hz receiver default. Is ICBM overkill as just a sub X-over?

I might eventually add a 2 channel or 750 in the future. So, I'm thinking that a bit more spent on the ICBM could pay off in the future.

Any suggestions on EQ for sub? I'm debating between Rane PE17, BFD and Art 351.

Thanks

Leon
