mustang guy Posted October 18, 2011 Share Posted October 18, 2011 Made in 1972, and they are worth $300-325 for the pair as is, IMO. Of course that could be wrong depending on where you are. Put them in the garage sale area of this forum and list them in craigslist locally, and you will turn them into cash within a couple days.

Malcolm Posted October 18, 2011 Share Posted October 18, 2011 Yep, K=1972. I have a pair from the same year. K22 CTS alnico woofer. K55V Atlas alnico midrange on aluminum K700 horn. K77 Electrovoice alnico tweeter. Type C Network. Sheet that came with them described them as 8-16 ohm speakers. If you want to see it all, just unscrew the back.

muel Posted October 18, 2011 Share Posted October 18, 2011 They are worth keeping. Baby says, "Move my Pack and Play to the sweet spot and crank up the Veggie Tales!" Quote Link to comment Share on other sites More sharing options...
mustang guy Posted October 19, 2011 Share Posted October 19, 2011 They are worth keeping. ... +1 One of the best speakers I have ever owned for any price. Quote Link to comment Share on other sites More sharing options...
muel Posted October 19, 2011 Share Posted October 19, 2011 You will find a lot of info here on how to tweak these but they are darn good with a capacitor upgrade from BOB. 40 years is pretty old for those capacitors. Well worth the $! Quote Link to comment Share on other sites More sharing options...
Malcolm Posted October 19, 2011 Share Posted October 19, 2011 Yep, the one modification I would make to them would be to replace the old motor capacitors used in the crossover. I use Solen Fastcap metallized polypropylene capacitors. Others have other preferences. You can read up on them if you do a search on "capacitors".

moray james Posted October 19, 2011 Share Posted October 19, 2011 At that age not only will the new caps make the speakers sound better than new they will avert possible damage to your amplifier. The stock caps are simply decades past their best before date. Great speaker the Heresy. Best regards Moray James. Quote Link to comment Share on other sites More sharing options...
