Have a pair of used stock Magnepan 1.7i's in for testing for dspNexus 2/8 use in my room.  This is with the original passive crossover in use.  Here is what the measurements show and what is possible with the system using REW for the measurements and frequency response corrections.

The 58Hz dip in response is the ceiling to floor cancellation at my seat with the placement of the speakers.  Both speaker channels are frequency corrected independently.

This is what correcting your speakers, in your room, in your listening seat can do.  And yes, they sound much better. 🙂

Stock passive crossover as setup:



Applied REW frequency response correction to the same speakers:

The use of a passive crossover is just so wasteful anymore unless one wants a simple set and forget setup. 


The best crossover is one in the digital domain!

I agree.

If people that own a speaker system and do not want to modify them for direct drive they can still see a large improvement. 

Later, if they decide to modify the speakers for direct drive they can use the dspNexus 2/8 for that as well with a different DSP crossover design, no new hardware needed for more improvement.
