MiniDSP 2x4 HD questions

[olds1959special]

I plan to use this with the pair of amps powering the lows of my main speakers, as an alternative to Harrison 100 Hz HP filters. I also thought maybe I could use the 2nd set of outputs for sending to my subwoofers? I'm just not sure there would be any benefit. I thought maybe I could optimize the crossover slope to match the first-order crossovers of my main speakers?

This won't work that well because of the 3ms delay. So I decided to try using the MiniDSP as a pre-amp, connected to USB. I'll send a HP to the four amps for the speakers, and LP for the subs.

Is this okay? Boosted the subs 6db since they are mono/single channel.

 

[olds1959special]

this is better

Best combo is 100 Hz 12dB LP on the subs and 100 Hz 12dB HP on the rest

I'm still relatively new to EQ and I'm pretty sure there are more experienced people on this forum and I would measure the subs and speakers together in REW to see what the frequency response is like and I would also check how they sound.

Curious to see the RTA results with pink noise, I've done it before a few times but I'm pretty sure with the ability to manipulate the crossovers so precisely, and listening to the different settings a few times with a variety of material, I've concluded that the subwoofer sounds best working up to 100 Hz, and the speakers sound the best working down to 100 Hz, with the same Butterworth 12dB slope. Measuring probably won't change that, and mostly when I employed EQ it was cut frequencies below 100 Hz which I'm doing now anyway.

I love the 200 Hz crossover / 6dB slope. It matches the main speakers design.

I was noticing I wanted more treble and so what I ended up doing was measuring with pink noise and reducing peaks (mostly in the subwoofers range) at around 40 Hz and 75 Hz aiming for a flatter overall response.
