Need speakers that can rock with just one watt? You found da place.

Do not assume Field Coils are better........

The field coil conversion, may, or may not be better than the original alnico. Do not assume, because its a field coil, that it is automatically better than the alnico !!

More than a dozen RCA filed coil drivers ( MI-1428B and MI-1443s ) I have personally owned, and have passed through my hands. I was an early user and proponent of these, ( and I owned six RCA Ubangie Bass Horns, all at one time ). Today, I am VERY happy having ALTEC alnico 802Ds, remagged and GPA re-diaphragmed. YMMV.

There are other areas where we can gain performance. IMHO, "I" would NOT ever buy a magnet "converted" 802 unless I was able to A-B them in a relaxed manner, over time, on my system. No-knowing - WHAT will sound best. You better have a GOOD amp and a good source, and optimized wiring / a truly optimized crossover, when you compare 'em, to make a good determination.

My post's point is " a field coil is NOT necessarily automatically better , AND, it may be automatically worse."

See if anyone here can figure out why this might be so, technically. I know someone, very experienced with early movie theater W.E. RCA, etc, who has this figured out.
