MiniDSP/Nanodigi digital crossover vs. analog crossover?

post #1 of 3
Thread Starter 

I am looking into building a set of open baffle speakers and the crossovers seem to be the hardest part to do well. High quality components are large and can get super expensive. So.... digital crossover looks like a viable solution, but I don't know if there will be any side effect from doing digital manipulation. Has anybody compare a system with DSP-type crossover to an analog system?

I went for the nano digi after hearing to many reports of high noise floor and reduced SQ with the standard minidsp. After all, the analouge signal from your swish DAC is digitized processed and then converted to analouge again through tiny little DACs. Can't be a winning situation for high end set ups.

That said, bypassing all filters in the NanoDigi should in theory not color the sound at all, but it does frown.gif not by much, but the soundstage and imaging suffer. So is a slight decrease in SQ worth the flexibility?

For me - probably not. I use full range drivers and was looking to cross at about 100-150hz to a sub. Easier for me to add the LF with the sub, and run the full range speakers as god intended. Means I'm still limited to moderate yet adequate volumes, but I have spent to much cash on revealing SQ to relinquish it for the sake of a XO.

Almost forgot about this thread, and thanks so much for the info!

I was also mainly looking at the NanoDigi and intended to tap out the I2s on the output side to drive NOS Dacs. I wanted to do BSC using the Nanodigi, for full range drivers, so your post really answered my questions. :smile:
