DOWNLOAD EW&WW ROARING SUBWOOFER, MOTIONAL FEEDBACK SUBARTICLE!

Shown above is one of the (many) prototypes that led eventually to the EW&WW motional feedback subwoofer circuit. As you can see from the number of cables the system didn't meet with the whole hearted approval of the distaff side. Still, some designs are too good not to be shared. Here a pair of dual voice coil drivers are mounted in a small infinite baffle case. The characteristics of the drivers shown, a pair of 200 mm drivers was not as good as the Volt drivers eventually chosen for the magazine design. Nevertheless the design shown gave a good account of itself and a new design has been prepeared for launching soon. The new design uses updated filtering and power amp circuit and consequently better audio response. Expect to see it here within the next few months.
