Build some sort of radial fixture to terminate the spring 
to a point that attaches to the speaker at the center of 
the dome or whatever voice coil cover is present. Or bend 
the last 1/2 coil of the spring over 90 degrees from the 
rest of the spring and attach the center of the resulting 
arc to the speaker.

A couple of 8 inch diameter long throw woofers should be 
ideal for this. I've done this with some 4 inch full range 
speakers and a one inch diameter spring, and it worked 
great.
