I would like to try making my Klipsch LaScala speakers both time and phase aligned by replacing their passive crossover with an active digital crossover running in a computer.

Here are the components I already have that I would like to use:
1) Klipsch La Scalas (2 speakers, each 3 way)
2) A Mac mini, ideally running OSX, but also willing to run Linux, and reluctantly willing to run Windows.

I am planning on getting a cheap second hand MOTU firewire interface, that would give me an 8 channel DAC.

I’m usually pretty good at googling stuff, but this topic leads to so many old and obscure pieces of hardware and software that I have no idea where to start.

Here are some questions:

1) Which is the most sensible calibrated microphone to buy to measure the frequency response, time alignment & phase alignment of my drivers? Should it be a USB microphone plugged into the computer, or an analogue microphone plugged into the MOTU?

2) Which is the most sensible software to use to:
– Predict & test crossover settings?
– Gather the info needed to time align my drivers?
– Gather the info needed to phase align my drivers?
– Perhaps even gather info needed to do room correction?

3) Which is the most sensible software to use to perform the crossover/time & phase alignment/perhaps room correction in real time over 6 channels?
– Do I create a static convolution file that a program like HQplayer uses?
– Do I run my audio through a piece of software that does all the DSP and outputs 6 digital channels to the MOTU?

4) How do I convert the measurements gathered in step 2 into settings used in step 3?

5) I know quite a bit about good stereo amps, but I don’t know much about the most sensible, most bang-for-buck way to tri-amp my speakers
– 6 identical mono amps? Which ones?
– 3 identical stereo amps? Which ones?
– A bigger amp for my woofers, smaller for my mids and tweeters? Which ones?
– A single multi-channel amp? Which one?

Any suggestions on where to start would be much appreciated!
