Just picked up a pair of HIP's....now for some questions...please

Recommended Posts

Just found a pair of Hersey HIP's for $250 in pretty good and original shape. Some cosmetic paint was pulled off probably from some box tape stuck on one. But I want to get them up to date. My questions are:

 

-Did all HIP's have the same networks? All drivers are original. I'll be ordering a rebuild kit from Bob.

 

-The backs are pretty stuck even after the screws are removed. Is there a secret to getting them off or is it just brute strength? I've taken out the terminal cup to grab hold of the back panel but, MAN, are they stuck!

 

-What was the original paint on these? black wrinkle. 

 

THX!!

Photos please.  You might try a hair dryer turned on high to loosen the back panel in small spots.  Once you get it started, it should become easier, but just go slowly.

 

Black wrinkle?  Do you  mean fiberglass?

Kool, I'll try the hair dryer. I reached in and it feels like there may be some glue/sealer in there, but very little.

 

Here's the finish damage. It's not that deep. I can barely tell the depth with my fingernail.

I just saw your other post in What I got today.  Those look like original paint/finish.

O.k., just got ths back off. The hair dryer wasn't hot enough, although if it were, it looks like some kind of double sided industrial electrical tape.

 

I took a #3 flat head screwdriver and seperated the mating surface from the inside with a hammer.

Same types of networks yes (HIE). Capacitors and woofers are different types depending on year of manufacture. Oil filled vs potted and EVM12L vs K-42 respectively.

3/4" x 1/16" neoprene gasket. Very good stuff. I got my roll from TCH web. Kudos to using the terminal cup hole as a grab hold instead of trying to pry along the seam from the exterior.

I have a pair of HIP with Type AA networks with Zener diodes.  I don't recall the serial numbers and they're in storage, but the round magnet K-77s & EV woofer tell me they're old.

Nice score, those woofers alone are worth the price paid! I really liked mine they had a great sound just couldn't get any real bass out of them but midrange was excellent. Set them on top of a pair of subs and you'll be good to go.

This one's o.k., he's completely declawed and woofer grills help.

 

Besides........I know better than to mess with him.

Look just like the ones I picked up last fall (mine have Klipsch painted just below the midrange).  I had the same issue getting the backs off that sticky gooey black caulking really holds.  I removed the terminal cups and just kept pulling from various angles.  I left my crossovers alone as they sound great and I wasn't going to put crappy Sonicaps in them.  When and if I do update them I will use much higher quality components in the networks.  I need to get mine repainted and feet on the other one as only one had the feet on the bottom.

Cats are naturally attracted to Klipsch HIP Speakers...

K-42

K-55M

K-77M

Networks: HIE

You got a really good deal, usually I see these listed for $500 plus. Anyway, here is the link to a build thread where I bought a single HIP in bad shape and did a complete tear down and restoration to make it into a boombox. There might be some useful info on painting or recapping the networks etc.

They may be old, but the EVM 12L's called "klipsch K42's" are THE super bad woofer. LOL.
