..******************SEE MY OTHER LISTINGS!!!*******
Here we have a REALLY beefy, meaty, high end 4" aluminum cone driver.These are the ones used in many high end stereo systems and pro audio/instrument products. VERY robust magnetic structures..

These weigh around 3 POUNDs each!

They have a RUBBER half roll high compliance surround
  The cone is a spun aluminum curve linear profile, which allows that 16.5KHz top end!!!
 They play easily down to 60Hz, and make awesome upgrades and replacements for hi fi and pro audio gear.

overall side to side-4 1/8"
over all diagonal-5"
depth overall 2 1/2"
magnet diameter 3 1/2"
mounting hole CENTERS diagonal-4 1/2" ( with dog ears for adjustment)
mounting holes side to side 3 1/4

 Use your imagination with these..  if you want to make a line array , let me know, and I'll do a significant price reduction on 4 or more units..
 get 9 or 16, and make a "Piranha" bass enclosure..
