That's beyond nearfield... At that distance the horn is nothing more than a little gain in the lower region.

I'll bite.  Why do you need a nearfield measurement?
I'm a data whore and always take measurements of each driver to make sure there isn't anything out of the ordinary before taking room measurements.  This is a great way to make sure everything is wired properly and there isn't any damage.  Good QC check.

+1. It's nice to have that as a reference in case something were to go wrong in the future. I do exactly the same thing.

Best,
Anand.

:lol:  No doubt.  I think they're about 140 lbs each.   :duh:  That's the only downside to them but you can't have it both ways, that's for sure!

Just imagine if the motor were ferrite instead of neodymium! Could be worse! The UH21V1 driver weighs 50lbs  :weights: If it was a ferrite motor it would be double that weight.

Can you just run these M2s with a regular 2 channel or 4 channel amp or do you have to use the dsp amps with the software for speaker adjustment?

Short answer yes.

Applicable answer.... for 2 channel youd have to design a crossover, you'll need a calibrated microphone and tons of experience, and even more patients. 4 channel can be done much easier with equipment Anand has pointed out.

Well, after months of waiting the (2) Funk Audio 21.0LX have arrived.   :o   Funny how 24" cube doesn't sound so big until it's in front of you.   :lol:


 


 


 


 


Nathan Funk even has wood lined boxes which is SO smart.  Wish more companies would do this for shipping large heavy items.

I know.  I actually thought about having one made into some sort of a chair.  Large is an understatement.   :lol:


No movies here for me!   :nono:

I forgot to show the "business end" of the cabinet.  Since they're a Master/Slave pair this is the only thing to see as the other sub just has a speakON.  This sub has two amps stacked but with one plate showing.
