You are correct... They used Jensen and Quam but only used 10 oz magnets...The magnet size is what determines sound quality on a speaker... My company manufactures both 5 and 10 oz but only up to 8 "...Now you make that speaker a coaxial and it will improve the quality by 50% or more...Speakers are just like radio's... The better the enclosure the better the speaker like a transmitter and an antenna...

The originals I do believe were made by Jensen.
