lorcoll Posted August 25, 2016 Share Posted August 25, 2016 Hi. I have a pair of 1984 Khorn and today I have bought a 1973 pair. The two pairs differ in the motorboard rail that 1984 don't have and for the size of the pyramidal blocks (inserts) inside the 3"x13" hole on the fix motorboard. I know that the best results is with the woofer screwed directly onto the motor board, but what the differences (if any) with the two type of blocks (it is smaller in the 1984 Khorns). I have attached pics of the two types. Quote Link to comment Share on other sites More sharing options...
lorcoll Posted August 25, 2016 Author Share Posted August 25, 2016 Why Klipsch has reduced the size of these blocks in the end of the 70's? Even the AK5 type has the reduced blocks. Quote Link to comment Share on other sites More sharing options...
stereohermit01 Posted August 25, 2016 Share Posted August 25, 2016 La Scala , too. The older lascalas have the big splitter. Reduced in size in the later models. May have something to do with the TS parameters of the later k 33 changing.Sent from my SPH-L720T using Tapatalk Quote Link to comment Share on other sites More sharing options...
stereohermit01 Posted August 25, 2016 Share Posted August 25, 2016 Now begs the question , which has the better bass?. The better lower mid-range blend to the mid-range horn?Sent from my SPH-L720T using Tapatalk Quote Link to comment Share on other sites More sharing options...
lorcoll Posted August 25, 2016 Author Share Posted August 25, 2016 The 1984 pair has the best bass but I have still to screw the woofers directly onto the motor board to see the first difference. For an objective comparation I have to mount the 1984 crossover too. I hope someone have already done the comparison to tell us his impressions.

Speakerfritz Posted October 7, 2016 Share Posted October 7, 2016 the square area from the tip of the prymid to the edge of the baffle slot is greater with the smaller "pyramid" . in an even prior version, the cut out was double in size. decreasing the size move the low end response curve so that one of the spl peaks was more in the middle of the 40 to 400hz range. the pyramid size change could be a further tweak of that.
