Thanks for the input guys!! I'm off to build my boxes!!

I have 4 atlas 12's that i am putting in my living room in 2 seperate sealed boxes. Wiring a pair together what would my final imp. be? I'm going to use a pro amp that puts out max power at 2 ohms but still cranks out the juice at 4 ohm as well. I'm kinda lost with this 4/2 ohm coil configuration. I also would like know what size box would be right too. I know there is a low, mid and high qts settings, does that relate to the 2 ohm coil being open, shorted or adding a resistor? If i shorted the 2 ohm coils and wired the 4 ohm coils in parallel would i achieve a four ohm load using two subs? If i did this to the other 2 subs and then parelleled them together as four would i have a 2 ohm load for all four? I'm jonesin' for bass........please help a guy out!!

So basically you can build a 1.25 cf box and just play aound with the 2 ohm coil to alter the frequency response?

If you changed the qt of the sub from high-mid-low wouldn't that essentially change the parameters of the sub? A change in parameters would constitute a different box size for each, wouldn't it? Dustin, your previous post confused me. You said you tried low qt and had better low end response, then said low again and it was punchier with not as much low end. I guess i want to get the lowest response i can without sacrificing to much spl from 30 to 60 hz..................hence the reason i'm using four. Any one stuff these things in different sizes of boxes other than 1.25 cf. for a single 12?

Definately something to consider. The Behringer and the Qsc amps Distortion levels are .1% at four ohm stereo and 1% at two ohm stereo. Not to sure if its that audible , but something to consider.

Would that be the low qts setting, using both coils?

I'm going to wire them up for a 2 ohm load and use a behringer ep2500 or a qsc rmx 1450 (two channel,not mono).As far as box size goes, is 1.25 cf a good size or would i get more low end output with a little bigger box, maybe 1.75-2cf? i also picked up a new atlas 15 but i am making a vented box for it and putting it in my home theater room. 5 new subs (still in original shipping boxes) for $200, couldn't pass that up!! What pictures would you like to see, the subs or the build?
