They retail at $1300 and can be found for $799 each.

I grabbed two of them just for testing on my metro and couldn't be more happy. I'm actually looking at some of the newer style boards either the 6.5kw or 8.5kw.

I guess I'll fill in the blanks...
Its a Zenon board that's used in... iirc old sundown saz3000, atomic at3000, Rd 3250.. ect.

Still have yet to put it to a test but will try in the next few weeks.

Price was right though.

It does look like the old RD 3250. Dunno if 800$ is really a great deal on 3K.... that's about what I'd be trying to spend on AB500.1 or Atomic 5K, etc.

I just made a new video and will upload soon.

$800 new with warranty is alright.

Anyways the test results are...

Dropping to 11 volts

AC voltage 57.7

AC amperage 51.2

Starting impedance 0.5 omh 1.12 ohm after rise

For a total clamp power at 2950 watts @ 11 volts..? That's pretty decent and that's rated specs!

SPL of 150.42dbs

i take that back... 3000 at 11v is nice!!!!

Here is the video of the clamp test

I know I say 57.1 AC volts but after watching I seen it was 57.7 lol

Not really underrated but not bad. I wouldn't want to drop $800 though.

I'd sell them for $599.

I'm going to continue testing though, trying to keep voltage around 12 volts and see what happens.
