steve schell on the rca 1428 |
 | | As far as I have been able to determine, the 1428 was the first loudspeaker to make use of phenolic resin as a diaphragm material. |
 | | The 1428 phasing plug was a magnificent structure, cast from aluminum, through which a number of radially-oriented (think spokes on a wagon wheel) slits traveled from the phasing plug surface to combine at the 1.5" diameter exit. |
 | | So why are we concerned with the 1428 in the 21st century, and why does Jonathan use them in his system, with all the "botheration" of finding these rarities, supplying their field coils with DC, etc? Because to many listeners, the 1428 provides the most vivid, lifelike midrange reproduction they have ever heard! |
