twistedcrankcammer Posted April 28, 2015 Share Posted April 28, 2015 Decided to take the K33-E woofer replacement from Klipsch parts. Should be here in 7 days. Reconing in my area was too costly. Thanks for all the help. edit: also ordered from Mr Bob Crites the AA cap kit. Should work out nicely once done. You could of reconed, had a better driver, a matched driver and had less in it if you would have called Tom! Roger Quote Link to comment Share on other sites More sharing options...
kg4guy Posted April 28, 2015 Share Posted April 28, 2015 Voice coil is blown in my K33B square magnet woofer out of my 79 La Scala. The other woofer is reading okay. I plan on keeping these many years so I am curious what I should do for the replacement. Here are my options and add if I forgot any... 1. Crites woofer (new) (Do not want to use the Cast Frame) 2. Klipsch K33E woofer with round magnet (new) 3. Used if I could find but search brings nothing of interest 4. Reconing service (I am in Ontario, Canada so reconing with parts could get costly) I am doing the caps as well since the speakers are out of commission for awhile. I have decided on Crites for the caps kit. Would you: A: buy one Crites or other K33E with round magnet B: buy 2 and replace both even thought the other is fine for now but is a K33B with square magnet C: look into reconing only if cost was a lot less then the price of a replacement woofer D: other.. add any other suggestions If I only get one woofer does having the original K33B square Magnet in the other speaker make any difference? I know the B is for Brownsville but what about the square vs round mag on the replacement K33's? The crossover decides what freq to send to the woofers but with one brand new and one 36 years old woofer would the sound be the same? Thanks I would get two Eminence Kappa C woofers really like the way they sound in the La scala . Quote Link to comment Share on other sites More sharing options...
mustang guy Posted April 29, 2015 Share Posted April 29, 2015 The drivers are all similar in the LS bass bin. The round and crites are almost identical. I have not plugged them into hornresp, I just put them each into a sealed 2.22 cu ft bass bin which is the size of the dog house. Quote Link to comment Share on other sites More sharing options...
mustang guy Posted May 1, 2015 Share Posted May 1, 2015 Has anybody ever tried re-centering and re-gluing the spider and the surround? In other works, if you carefully cut away the spider from the magnet and the surround from the frame, perhaps you could re-cone it with the old cone. Is that a nutty idea? Look at this thread and you can see what's inside the woofer in question. Maybe you can see what I mean... https://community.klipsch.com/index.php?/topic/140231-how-to-recone-a-k-33-woofer/ Is the spider glued down firmly? If that popped up, things could be out of alignment. FYI, I just pulled a K-33 square magnet from one of my LaScalas. The VC was rubbing, and the sound was as you described. I inspected it, and the spider has come unglued. I have no doubt I will be able to glue this in place. My only doubt is wether I will get it centered. I will let ya'll know...

djk Posted May 1, 2015 Share Posted May 1, 2015 "My only doubt is wether I will get it centered. I will let ya'll know..." That's what shims are for. Shim it, glue it, let the glue dry, remove shims, install dustcap. 1 Quote Link to comment Share on other sites More sharing options...

Shim it, glue it, let the glue dry, remove shims, install dustcap. OK, I'm dumb. Ditch the dust cap and remove any potential for misalignments.

Thanks gfong, The original square magnet woofers you have now are better than the new K-33E round magnet ones. Personally I would have the one you have fixed if possible by a competent professional or recone both. Bob Crites replacement woofer was designed around the K-33E square magnet woofer from my memory. I've owned multiple pairs of Klipschorns and LaScalas at the same time. My brother in law lives about 5 miles from me and owns Klipschorns as well. I took a LaScala over to his house and we personally switched out and A/Bd the K-33E round magnet woofer, the K-33E square magnet woofer, a Crites steel frame woofer, a K-43E steel framed woofer, a K-43E Cast frame woofer, a K-44E cast frame woofer, and an Electro Voice EV 15W-K woofer. The K-33E in square and round were used of course in Klipschorn, LaScala, etc., K-43s were used in Pro LaScala, and MWMs, the K-44E was used in Pro Klipschorns = TSCM, and the Electro Voice EV 15W-K was used in early Klipschorns (the "K" denotes Klipsch) The Electro Voice EV 15W-K sounded the best to both of us, and I am going to be selling a pair of these that have been fully restored shortly, but you are talking several times the money of the Crites cast frame woofers. PM me for pictures and a price, but I wont be able to reply until Friday. I know a reconer in Ft. Wayne, Indianna that is the only guy authorized by Electro Voice to recone their obsolete speakers that's work cannot be compared to anyone elses and he could fix or recone your speaker or speakers correctly. His name is Tom and his phone number is 260-494-1677 Roger hi - Roger - can you send us a picture of this EV 15W-K - is this a 4 ohms speaker - or 8 ohms - just curiouds to see this beast - I always fancied EV products - they absolutely sound great versus the Eminence - by the way - Klipsch is making woofers , that was shown in the Hope Gathering this year - as well as new mids for the SCALA - I am curious if KLIPSCH will have a replacement in house made K33 - Quote Link to comment Share on other sites More sharing options...

Actually the idea is not nutty at all , a lot of big band Technicians do that all the time while they are on tour as spare drivers are not always available - they hear the rubbing and they have jigs to re-align the cones -if I remember well - the EVM series woofers have the voice coil as a seperate part for over 30 years - Quote Link to comment Share on other sites More sharing options...
mustang guy Posted May 4, 2015 Share Posted May 4, 2015 Quick update. I repaired the detached spider, and the voice coil does not rub. I took pictures, and will be posting a how to thread when I get home tonight. I will need to buy a new dust cap and glue it on, but I think this is going to be a success story. We'll see... 1 Quote Link to comment Share on other sites More sharing options...

LarryC Posted May 5, 2015 Share Posted May 5, 2015 (edited) hanks a lot Roger - one can see that quality was once not an object - those EV woofers were just the best for KhORNS Sadly, I think that was true. The deep organ bass was phenomenal, as was mid-range clarity past 1,000 kHz. I bought two used, but had two problems when I switched them into my AK-4 K-horns: The sound was unbalanced, like the crossovers would have to be re-engineered They apparently picked up more EMI than the K-33's, so I had unacceptable hum. My house electrical service entrance was too close, and I couldn't move things around that much. Edited May 5, 2015 by LarryC Quote Link to comment Share on other sites More sharing options...
