[T9X 10+ year member]

I've searched high and low for the T/S parameters on the Atlas but all I can find is a link to a deleted page on the AA site server. Someone help please?

No problem.

How about for the 15" Atlas?

Another question:

I knew the "2ohm" coil is used only to alter qts and isn't supposed to be powered. Can you explain the procedure needed to accomplish each of the Q settings?

The Atlas 15 stock is going on sale soon and I want to see if this driver would work for me.

Anyone know the T/S for the 15 atlas?

 

[CBFryman2 5,000+ posts]

I'll get them when I go home.

The 2ohm coil can be powered if you want a 6ohm driver.

To change the Qts you either leave the coil open, put a wire jumper on it, or put a resistor on it.

Found em finally.

I am thinking about trying to grab the 8 that will be for sale soon. Good replacement for the RFs I use in my home IB.

/Your decision making.

 

[IamDeMan 5,000+ posts]

LMAO. Nice way of putting it. Unfortunately they would only be getting about 500 RMS until I got a different amp as well. Even with 500 watts though in IB WinISD shows them just under their linear excursion limits at 18 hz with 500 watts.

 

[CBFryman2 5,000+ posts]

Well they are bottomless so you dont have to worry about damaging them mechaically all too much anyway.
