I will take more video for sure, the videos were taken by my son who has a totally different video style than myself.

This is a satellite view to help with some scale. I have plenty of schools with large open parking lots but I am not sure if I can get a better/lower noise floor at them. I will set up here and give it a run, if I run into problems I'll find a new location.

I tried to set this up Saturday but the wind (I forgot about that LOL) had a 90db noise floor during gusts so it was aborted.

I also realized I skipped the dampening foam (I guess I got too excited) so I need to revisit that.
You need to do that before any more testing.
I found a new 1.5" to 2" foam mattress topper when cleaning up recently. I currently have quilt batting stapled in the cabinet, would it be worth it to swap the batting for the mattress topper foam when I pull it down again to duratex?
I would.

Good deal, I will put that on the to-do list.

Thank you

There's no advantage to foam over polyester batting when they're of equal thickness.

The batting is much thinner really in my installation.
It would take another layer I bet to get equivalent thickness.

Worked on the final details today. I bought a corner handle that I thought was going to be perfect but evidently I can't read a tape measure and it is sized perfectly for a toddler...

I did what I had planned on doing originally, build a handle from 3/4 EMT and wood. This was a little more challenging than I thought, but in the end it came out awesome.

I'm working on a 2 LED, aux input panel for the front and a rear panel with power source selection switch, AC input power jack and a GX16 aviation connector for the DSP programmer.
Both panels will be inset 1" with proper 3/8" radius on the cutout.

I am still thinking about adding dynamic bass knob, but it might get hidden somewhere, I have learned that people like to turn knobs when presented with the opportunity.



As usual pix are sideways but will be correct when clicked.

In case I got misunderstood, I meant the pocket for the grab handle.

Trust me I had a few OH S*** moments where I wondered if I had done just that. :loler:

Got the LED, aux port installed. I'll paint the aluminum plate before permanent installation and glue it in with some silicone.

Phase one of the logo is installed, this is a thin piece of plywood around 1/8" hopefully I can make it look good when it gets duratexed. I haven't decided exactly how I am going to handle that just yet.

Got the rear panel installed. Power button selects battery or 5.5mm power port for AC power brick. The 6 pin GX16 connection is for the KPX programmer to the DSP chip so it can be remotely programmed with out having to open the cabinet.
