Marvel Posted February 28, 2023 Share Posted February 28, 2023 The newest midrange-tweeter driver on the expensive Heritage Jubilee are Celestion. Not sure about other heritage models. The Celestion also has a custom klipsch designed phase plug for it. 1 Quote Link to comment Share on other sites More sharing options...

Marvel Posted March 1, 2023 Share Posted March 1, 2023 Klipsch Driver Manufacturer Codes: Example: K-33-E would be the "Klipsch", part type 33 (15") woofer from Eminence. The suffix letter code generally referred to the Klipsch assigned origin/ manufacturer of the driver. B = CTS (Chicago Telephone Supply), Brownsville TX P = CTS in Paducah KY (woofers only) R = Rola (an additional "R" either stamped or handwritten also indicated replacement (often seen on K22's and K- 24's) D = K-77-D; From 2006 to the present. Essentially a K-77-F (see below) with an integral recessed mounting flange. Permits flush mounting of the tweeter from the rear, per the “Z” brackets for pre Feb 1983 Klipschorns (KH Update kit: part # 1006969) F = Philippines supplier that purchased the EV tooling (e.g. K-77-F) EV = Electro Voice (early K-33's e.g. "EV-15WK", also EV 1828 was used as the K-56 for Cornwall in 1974) G = Atlas (for K-55-G for Cornwall 1981-1983) J = Jensen (Also used for University drivers in mid- 1950s; e.g. K-5-J - University model 5A HF, and SAHF) H = Heppner (K-52-H in Cornwall-II’s) K = Klipsch (Pyle - Klipsch purchased Pyle. Drivers formerly assembled in Hope, Arkansas and subsequently in Hot Springs, Arkansas were then moved to Pyle in Huntington, Indiana) E = Eminence (Primarily woofers) V = Atlas (see also notes below) M = Electro Voice (also for the Eminence K-33-M in 1967) X = Atlas (e.g. K-55-X) Ti = Titanium series (new design with titanium diaphragms) 5. The V on the midrange & tweeters can also indicate 'video shielded' 6. A significant number of "replacement" drivers, e.g. late model K-53's, K-76's will have no manufacturing code or date code, e.g. "blank" as in nothing at all. 7. On Heresy drivers, the number K53 indicates the driver/horn combo part number, which is a K52 driver and K701 horn. 8. Electro Voice also produced the "round magnet" T-35 tweeter, but later versions were simply labeled K-77. The first shipment of Electrovoice T-35 tweeters designated as the K-77 were received on 26 August 1959. The K-77 is first used in a Klipschorn with the serial number 1445 on 15 October, 1959. 9. Electro Voice also produced a K-56 (EV-1828) as a temporary replacement for K-55's in 1974. Found on Cornwall's, La Scala’s, and Belle's produced in that year. 10. Atlas produced the K-55X's (PD-5VH); and the PD-5VH is the K-55V (still available from Atlas and other vendors) 11. Stephens (P52LX2) woofers were used from 1949 through 1953 on the Klipschorn's. In 1953, the Stephens P103LX2 was used. In 1954 University mid/and high drivers were also used. 12. From 1950 through 1961, the Stephens woofers were used interchangeably with the Electro Voice EV-15WK woofer and the early Jensen K-33-J's in the Klipschorn's. 13. These codes also apply to drivers used in Chorus & Forte’s 1 Quote Link to comment Share on other sites More sharing options...

The Klipschorn and La Scala use Atlas midrange drivers (PD5-VH) and Celestion tweeters. Eminence for the K-33 woofer. Cornwall IV and Forte IV use Celestion midrange and tweeters. Woofers by Eminence. Model numbers written down for the Celestion drivers somewhere - I can’t remember where I put them. 1 Quote Link to comment Share on other sites More sharing options...
