Changing topics. I went to three concerts this year and all of them
were big shows and to my surprise, the SPL of these shows were not
what I expected. I think the city ordinances prohibit the higher
SPL levels that I used to experience at concerts. All the shows had
the J line arrays. I counted the stacks and determined that if I cut
the array in 1/2, the concert arrays would fit in my home -> lol ....
and while it seems crazy, it doesn't to me. It's nice to have high
headroom and low distortion and the volume knob is always adjustable.

Then I was looking at the costs of those higher end line array modules. LS9900 is sweet, but the MSRP is $6K per module, lol...

8 per channel -> expensive.

This particular unit used a very nice pro magnetic planar, PRD1000, look up the specs, amazing. I have something similar and it's worth the high dollar.

They have some lower cost modules with the cheaper PRD500 planar.

There is another *new* solution that I think might be better from
a different prosound vendor.

I guess if money was no object, I'd probably just buy these and hide
them behind the curtains, hehehe..
