juniper8 Posted May 19, 2010 Share Posted May 19, 2010 I picked my first pair of cornwalls in late march of this year and like many fell back in love with audio. I picked up a second pair yesterday that are very rough! the searches that i have done have yeilded very little. I just bought these to hear the differences and for 150.00 it is worth the lesson! so here goes unlike my first pair which are cbr's with metal horns these one's have metal tweeters and plastic midrange horns, because the cabs are bad should i make new ones? if the sound would be better than my 1980 cbrs i would definetly do it! the label says cbr 8437683 and 4 they have b-3 crossovers with a clarostat 200 ohm ceramic something attached to the tweeters, the tweeters say 824 0047 8936 with an r on them? midrange says k-57-k? the woofers are k33e, any advice or info about these would be great thanks!

BS Button Posted May 19, 2010 Share Posted May 19, 2010 With a careful application of bondo type wood filler, you could just re-use the original cabs and apply a new veneer coat of your choice. There are several threads in here about that subject. If I'm not mistaken there are actually two B-3 crossovers and both are good in my HO. I don't know about that resistor in the path of the tweeter, may be a makeshift type deal to protect it from blowing. Sounds like you have what we commonly refer to as a Cornwall 1.5, somewhere during the changover. This is good because of access to everthing through opening the back panel. The sky is the limit on conversions. The K601 (plastic) mid horn only uses a bolt on driver, I think: or the K57K in other words, and that is a limitation unless you can locate a couple of k600's (metal threaded): they are somewhat scarce. At any rate, most folks on here wouldn't hesitate to change out that horn, anyway (but you'd have to change the motorboard). $150 is a steal,,,great pick up. Ahem...we like pic's here...post them please. BS Quote Link to comment Share on other sites More sharing options...

Groomlakearea51 Posted May 20, 2010 Share Posted May 20, 2010 Take a look at this thread in regards to restoring a "cosmetically challenged" pair. http://forums.klipsch.com/forums/t/117315.aspx The "R" may refer to that the original K-77's were "blown" somewhere in their early career.

juniper8 Posted May 20, 2010 Author Share Posted May 20, 2010 wow! what an amazing job you did! You should be very proud, and I also like Igor! I need my own IGOR. I have very little woodworking skills so refinishing may not be an option, I think I could build a new cabinet and maybe find someone who wants original cabs for a project such as yours! I doubt many would have the same outcome as yours! Masterful execution!!! Great links!!! Thanks Quote Link to comment Share on other sites More sharing options...

WE looked at alot of posts about it way above our heads If someone can give very very very simple directions how to it it would be great!

BS Button Posted May 20, 2010 Share Posted May 20, 2010 Dont get discouraged on veneering, especially if you have the skills to build new cabs. It's really not that difficult..go with a paper backed product and the iron on method first; pick a less expensive veneer for your first project. We can guide you through...especially groomlake...Need to look at Gregs website, too. Me no can linky...maybe somebody else can...show him some of Gregs work... www.voltiaudio.com I think BS[bs] Quote Link to comment Share on other sites More sharing options...

winchester21 Posted May 21, 2010 Share Posted May 21, 2010 I would also looking at examining the prospect of modding-upgrading the innards of these while your at it. Crossovers- drivers- ect. I am not the expert on the subject but there are many on this forum. Some of the older CWs had weak links in terms of internal components. I am going through mine at some time in the near future. Harry O is up to speed in this area - you might check with him Quote Link to comment Share on other sites More sharing options...

BS Button Posted May 21, 2010 Share Posted May 21, 2010 Those were likely hanging in a club at some point and they were probably tired of blowing tweeters. They can be restored to perfection, though...and you have the perfect substrate...Raw Birch.. Take out those resistors and hook em straight up... Go for the veneer job, when you have time...
