less than 1k$ for a pair of used Heresy IV wow , how can that be possible ?........., run dont walk

stick to buying a pair of klipsch K-79 or K-75 or the newer K-107 Ti tweeters , steer away from cloned aftermarkets

You wired the new Power Supply incorrectly or you may have a DOA Power Supply or a bad main board,

great news

beautiful , GLWTS

..bump

wow that's great news

PWK tested the K-55V with klipsch's various horns and so did the Engineering Team , this " plane wave tube measurements " based on Atlas Sound's testing methods has nothing to do with Klipsch unless one believes in fairy tales

I doubt it

the midrange horn of a Belle is smaller , you're better off with a Lascala , the mids horn of a Lascala is 400Hz , the Belle mids horn is 500Hz because the speaker s not a deep , therefore the horn had to be made shorter ,the quality sound will favor the Lascala and btw , the LS shares the mids horn with the Top of the line Khorn

850$ sounds great- -modifying / drilling into the Factory terminal cup would affect the resale value

Go Chiefs go , 10 points spread 17-10 Ravens

you're projecting a subconscious image of yourself

tx for the great review

the KP-450A are klipsch Pro speakers with casters and handles , your speakers were Made in 1993 based on the serial # you provided - cabs are 3/4 inch birch plywood , the cabs come in 2 pieces , the Low Frequency cab has two 15 inch K-45-E woofers , the HF cabinet has a K-69M compression driver with a K-501 horn

tx for the confirmation

the specs of the 70's -80's K-55V with the original Atlas diaphragm indicated that it extended to 6KHz whether single or dual phase plug and so does the K-55M , but the K-55M was hotter , and we all know that the newer 2001 K-55X , PD5VH including the newer D-20GB diaphragms only extend to 4100Hz .

Jesse , do both passives have the same diameter or is the KD-15-ST a tad larger , does the KD-15-ST fit in the Forte II

great idea , buy an AA kit from JEM + the missing parts , skip the Zener diodes , if you dont like the sound of the K-55M with the AA , you can sell these off and buy K-55V drivers , both K-55V and K-55M extend to 6KHz as long as the diaphragms are Original .

too bad , that the Forte series does not have a 15 inch woofer option , call it a Forte IV Plus or X , but please , give us a bigger woofer

Forte , Heresy , LS , Khorns , Jubes , same thing
