AQ 2200D tested!

[Jeremiah25 10+ year member]

Part 1:

I used one of my old HD3 12's with dual 2 coils. Amp running at 1 ohm nominal. The is the same box I used to test the AQ1200 and the HD3c's when they came out.

VAC: 66.2V

CAC:16.52A

Apparent power: 1093.624 watts

Reactive Impedance: 4.007 ohms

TL score: 143.8 legal dash

Compared to rated power: 1093.624/750 = 1.458 or 45.8% over rated power!

Part 2 comming soon

That's a hell of an impedance rise. What frequency tone was used?

 

[jnralp00 10+ year member]

so roughly 1094watts @ 4ohms?

the aq/dd subs always have wickedly high impedence rise, when ive used them anyway...

really nice power at 4 ohms for sure

Very nice results...

Different box might yeild lower rise in impeadance.

Part 2:

I picked up the old HD3c 12 prototype from AQ (I'll admit I missed it) Dual 2 copper coils. Running the amp at 1 ohm nominal.

VAC: 65.9V

CAC: 19.39A

Apparent power: 1277.8

Reactive Impedance: 3.4 Ohms

TL score: 145.7 (legal dash)

use a pair of the old hd's @ .5 ohm roll into the volume and see what kinda power we can get @ 2 ohms //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

That's about what I usually see for impedance rise. I played a 49hz tone.

it may not be louder , but you could try playing a different frequency out of the impedence spike of the box to help get the imp rise down...

What kind of power supply you giving it? 4ga or 1/0 power wire, battery? Voltage drop?

Good info so far.

There is a part 3 comming....sometime. Probably with 4 12's though //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif (I'd have to build a box or use a prefab for 2 12's.......I'm way too lazy)

2 NSB 90's and about 20 runs of 1/0 to my distribution blocks. I've just got 4 ga running from the dist. blocks to the amp. I might stick some 1/0 in there to see if it gains anymore.

prefab ftw

I'm not that concerned about it, but the imp rise does go down considerably at about 30hz.
