Loudspeaker foam rot - can we make a list of the affected models? (I'll start with the Red Line 60)
in The Workbench · Jul 8, 2009 13:43I came up with a radically new modification last year and now have a wonderful sounding pair of Redline 60s. Many folks have used my suggestion and love the bass they are now getting and will never have the foam issue ag…

in The Workbench · May 3, 2009 17:13Many folks have come to me for help to convert their Redlines using my redesign and replacment of the failed ABRs. I have been asked to sell them woofers and tweeters because some have burnt crossovers and have been over…

in The Workbench · Jul 16, 2008 22:29Hey guys, I spent 8 hours Saturday night and have them installed in my home theater. They are beautiful, especially with my red pinstriping instead of the clear plastic bands. The red matches the red around the housing. …

in The Workbench · Jun 27, 2008 18:38Hey Puncher, I called my Speaker Surgeon again, and they said they would replace the ABR rubber if "I" could come up with the replacement parts, in other words, if I would do all of the R & D to have a product that would…

in The Workbench · Jun 26, 2008 19:05Puncher, I agree that the 100 volt should be plenty. I chose the 400 volt Solen caps because of their build and audio quality. I've used them in many audio applications with outstanding results. They are a French company…

in The Workbench · Jun 26, 2008 11:51Puncher, That really suprises me!!!! Electrolytic caps do fail and die over time, just like an electrolytic automobile battery. I noticed a tremendous improvement when I went to the higher grade Solen capacitors & Mills …

in The Workbench · Jun 25, 2008 15:46Peter : Nice site! Just so you know, the RL60s cost £225 in 1985 - about $400 - and when discontinued as RL6000s in 1996 cost £450 or about $900. The later speakers had a reflex port rather than the ABR but were the same…
