@amirm would probably say that you can setup the speakers using measurements only (e.g. REW).

Amir, how is your 6-axis setup going?

Thanks... the ultimate goal is to have as flat of response as I can below 1k by just using good positioning techniques and speaker controls without having to resort to outboard digital or analog EQ. This is what the consumer is left with. Once they purchase a speaker, the dealer may do the initial setup, but what happens after 1000hr. of breakin.. or if you insert a new piece of equipment, or if something in the room changes?
The speakers were originally set up by the dealer by just using a tape measure and listening. All controls have remained at factory default.
I'll post a pic this evening.



Though this testwould suggest the RS meter is fairly accurate, except for below 31.5Hz where the corrections are from +5dB to +20dB as stated in both of these links.

Which according to my graph, the tracing below 30Hz is way off the charts!

This is why I wanted to use my Earthworks M50. I'm sure a few can atest to the accuracy of this mic. I'll try to get it working this evening.
I'm guessing you're familiar with UMIK-1, which is supposed to come calibrated, and is cheap/USB. Perhaps that is a solution?

I use an Earthworks M30 for my room calibration. I have 2 JL Audio f112v2 subs that came with their own mic. I can use it with their onboard DSP for sub setup along with my CR-1

Nice. I wasn't aware the JLs came with the mic, but that's great, isn't it? Really great sound potential. I wish I had room for that.
