I've never used the miniDSP but can't you adjust/balance the levels with it??? Volume adjustment is about the "easiest" digital signal processing you can do!
Yes it's possible to adjust digitaly for every output. I'm confused on how digital volume works. I've read that lowering volume would lower the number of bits. Also that there's a possibility to raise SNR.
I hope you're measuring your room? ….Diagnosis before treatment! But, you need to measure your room & speakers together so you can't finish the room treatment before the speakers are done.
Yep I bought a umik-1 and did a lot of measurements. I'm still waiting for some comfortboard to arrive.
QuoteHorn loaded compression driver : TAD TD-4002, 110db/wI assume you'll be making some measurements (with a horn attached and the woofer in a cabinet)?
Woofer : TAD TL-1603, 97db/W
I already measured the horn while investigating a ~ 1 khz to 2 khz dip (that the reason I want to test an active setup and to change crossover 800hz to 600hz or 650hz). As well as speakers, mostly in room due to size. It won't be a problem to level match woofer/driver with the DSP as well as Time align them.
The Internet says the compression driver is 16 Ohms,. If that's true that means half the power compared to 8 Ohms (-3dB). (With the same amplifier & settings). Do you have the gain (or sensitivity) specs for both amps?
I have on hand for experimentation a :
Pioneer SA-9900 for woofers
Luxman R-114 for drivers
There's not a lot of informations about this one on Internet.
If your speakers have an existing passive crossover, maybe you can figure-out the (existing) high-frequency attenuation. There should be a voltage divider (AKA a "pad"), or a potentiometer or a series resistor.
If there's a potentiometer it's probably audio-taper (non-liner) and you'd need a multimeter to measure the resistance ratio where you like it.
Crossover is tad TN-4 woofer 36db/oct, Driver 12db/oct. No pot (I had one but I removed it since it is not needed. Parts for the crossover are covered, so I didn't break anything in case I would sell them.
