Well, upon insection of the voice coils this morning I will say I was giving these drivers too much power. The voice coil on the living driver is dis-colored (blued) pretty much top to bottom but no burnt spots. the cooked driver, well, the VC is cooked.

I wanted to take pics, but I ended up inspecting through the vent holes and they have screen on them so no go on the pics.

In my defence I want to say that distortion is VERY HARD to hear in these frequencys.

As far as setting everything up I think I did fair, I just pushed the drivers to hard with the wrong/right material playing. like I said I was showing off the drums to a drummer friend and got carried away with the volume.

As of now I am leaning towards using an actual subwoofer for a mid-bass now that I now I only want them to play up to 400hz. I have some free sonys somebody gave me SO for now I will install a couple of them. Like I said they were FREE.

I guess the tittle should of been "smaller amp???". I feel like a jackass. I guess I learned why speakers are rated the way they are. Not that I shouldn't of already know, but........

BTW the crappy Sonys are installed for the moument.

Well, the sonys are definetly HEAVIER than the Aura's. I felt the difference right away opening/closing the doors.

I think I am definetly switching mid bass drivers to something rated for a little more power AND MORE EFFICIENT. The Auras are 84db@1watt/1meter and the sonys I put in temperarly are 88db@1watt/1meter, I already notice the difference in output, even on the same amp and gain setting. Well a little lower on the gain.

I am looking at the Daber Audio 10" in the SSA store and it is looking tasty. The Daber's will handle 600watts rms and are 88db@1watt/1meter.

I am open to suggestions for a heavy duty 10" sub that will play up to atleast 500hz.

There are many more important things to consider than sensitivity. The change in relative output could simply be a difference in frequency response and wholly unrelated to the sensitivity. It's also important to consider how the sensitivity was rated as there are many things that can be done that makes two different "rated" sensitivities not directly comparable. I would look for performance within the intended bandwidth, distortion performance, how the T/S fit with your intended use, etc long before I considered sensitivity.

As for drivers, what is your budget?

Damn bro, sorry to hear about your misfortunes with the midbass speakers I have faith in you though on finding a replacement that you'll be satisfied with

My budget is 400 bucks for both drivers. My budget for a bigger amp is. 600. So A thousand for both.

I want to say I got greedy with volume. With the wrong signal is how I killed the driver. I know the moment it happened.
