I use the Velodyne SMS 1 for the low pass to my sub. It's a digital crossover with a parametric EQ. I run my mains full range with no high pass x-over employed. I've never been a fan of EQ or tone controls but I have a nasty room mode at 40Hz that muddies the sound and makes everything seem bloated. That said a number of the speakers I've owned are stand mounted small speakers with a sub. The SMS 1 not only allows me to flatten that hump, it does a great job of integrating the sub with the mains. I can select the x-over in 1 dB steps and choose 6 dB through 36 dB slope / octave. I use a steep slope right around where my mains roll off and it eliminates that double bass that can occur in the x-over region.
Digital crossovers
Are crossovers "tone killers" as Zu Audio says?
Are digital crossovers a solution?
Much of our source material is digital already: e.g., CDs, ripped CDs, downloads and internet listening. I wonder if a digital pre-amplifier separating the music by frequency and sending the result via the analogue amplifier direct to the appropriate driver would/could produce awesome results?
(I wonder what the crossover slope would be? Would it be absolutely discrete, with absolutely no overlap between drivers? Or is a small amount of overlap necessary even in the digital world?)
