Sundown SD-2 10 d4
Dual 4ohm coils - 500 watts rms. This is essentially the shallow version of an SA-10 made for tighter spaces or those who would prefer to use a sealed enclosure.
This was previously used and reconed. It has not been powered since the recone. If you listen carefully you can hear a small piece of debris in the motor that rattles if you are holding the speaker and shaking it around. I did test this and the piece of debris does not affect the speaker's functionality at all - just something to be aware of. The debris likely got into the motor during cleaning and since there are no backplate vents I am not able to get it out without tearing the sub apart.
4. Price: :
$80 + shipping - I actually have 2 more of these that I can build to match if you are interested (they would not have any debris in the motor therefore would cost more)
