Rebuilding vintage Rogers Studio 1 monitors


Had to delete this attempt.  Need to figure out how to embed photos.

Having rebuilding many loudspeakers the Xovers is the weakest point

in 90% of speakers capacitors  in old speakers dry out ,your speaker needs a total rebuild ,resistors ,mills resistors or top quality path audio 

Millflex make excellent copper foil paper oil at decent prices , are lower cost Auricaps XO ,and inductors Jantzen make very good quality ones and for sure rewire , Neotech Teflon -6-9s Copper 

awg18 for the teeeter, and awg 15-14 for kids, Bass, and put copper loudspeaker terminals , VH audio WBT next gen they are only $40 each , if you are going to rebuild do it right a big step up in quality. The Xover for sure is dried out.

 

I Recognize and Appreciate your efforts… (insert applause here)… seriously though, Nice Job. Next time though, use a can of Millstreet or Moosehead… for better bass.

When you take things apart, the small gauge OEM wiring of equipment that built the success of so many Makers will surprise you. It is hard to resist ’good/better/best’, but you understand there is much over-doing of things, especially wire gauges.

Use proper speaker wire gauge related to the length from amp to speaker (relative to the driver's impedance).

Inside, insignificant distances: crossover wire feeds a voice coil. any substantial signal will burn the coil wire, i.e. there ain’t much juice involved

@ticat Dude, you got a loud laugh when I read your reply!  Thank you, and thank you.  While more bass is always better, no Millstreet in my area and no Moosehead in cans.  Besides, half the fun is the improvisation!  The Molson was there and cold...

@elliottbnewcombjr Exactly!  And thank you for the Roger Russell citation.  Lots of folks here have argued interpretations of fundamental physics of electricity and electrodynamic devices.  The Rogers interpretation still works well 42+ years later.  I feel that says everything that needs to be said.

Nice story.I am working on restoring my second pair of these wonderful speakers.
