Hi all!
New member here, mainly registered for dspNexus 2/8. I'm really interested in it and have a question, hoping I can find the answer here.
Some background: I recently built Bit**es Brew, a 3-way dipole speaker designed by Perry Marshall. The active crossover was implemented in a miniDSP FLEX. Perry shared a DSP file that can be loaded into the miniDSP platform. It includes the crossover, PEQ filters on each driver, and a 2048-tap FIR filter. I started from that and made quite a few tweaks to match my build, as well as account for batch variation, especially in the tweeter, based on gated REW measurements. The FIR is a bunch of coefficients (b0=…, b1=…), which I have zero understanding of.
With these efforts, I'm quite confident I've reached the intended design objectives, and it sounds really great. The only complaint from the audiophile in me is the "sound quality" (or whatever term you'd call it). I'm used to very high-end DACs, and I'm quite sure I'm hearing the limits of the miniDSP. While looking for better-sounding alternatives, I came across a mention that Perry had once met with Danville Signal and recommended their dspNexus.
So I have two main questions (forgive me I'm really not a DSP guy):
1. Given that dspNexus 2/8 uses Audio Weaver DSP, how difficult is it to "translate" the xo settings and PEQs into Audio Weaver? For example, will a filter with the same frequency, gain (dB), and Q in miniDSP behave the same in Audio Weaver?
2. With that set of FIR coefficients (b0=…, b1=…) in 96k sample rate, is it possible to use them seamlessly in Audio Weaver?
I hope these questions make sense. Thank you.
Pei
