The low voltage outdoor lighting power cord at lowes and Home Depot had exactly the same 12 ga. stranding as the 12 ga. speaker wire and was a fraction of the cost. Also has a very durable jacket as it is meant to be buried.
It looks like its about $36 + tax for 50 foot roll of 14 gauge, $39 for 12 gauge (cerrowire brand made in usa) at HD, is it really cheaper than bulk zip cord by the foot ?
-
Is Zip Cord the brown or black "lamp style power cord" sold in bulk at HD or Loews ? Cannot seem to locate it on there websites. Do they still have it ?

It would be really cool to compare caps, just wish I had more patience and time to let things breakin rather that just listening but with winter coming may just do. My 78' Cornwall have Sonicaps and sound ok, perhaps a little too bright sometimes ? I have a set of original oil (non leaking) caps here, and have been curious about the JEM caps.

there's nothing special about the screws -- just take one to your local hardware store and match it up. if you're looking for something bigger, just get one size up.
@Audible Nector was speaking about an alternative screw he successfully used, thats why I was asking him for the part number. Thank you.

I just played some bass heavy music and placed my hand on the back panel, I could barely feel it vibrating in the middle and on the edges by the screws there was absolutely nothing at all.
I'm not running a dance club, so I won't worry about sealing the back panel and just use the 12 screws supplied by Klipsch.
FWIW, YMMV, etc.
I'm playing jazz mostly at moderate volume and can feel air escaping from mine in the back when there are deeper notes. YMMV

Most of these speakers have had the backs off a time or two. If anyone bought Cornwalls used and didn't pull the backs first that's also recommended and another reason they get removed, etc....to make sure what's in there should be 🙂
When the backs are removed, or just simply mounted for 30-50 years without alteration, yet with 100db woofer pounding over it's life there's bound to be a bit of vibration. Without a "cushion" - think "window seal" there's going to be a chance for a smidge of rattle or vibration.
The gasket isolates that, the finish washers widen the screw head to make sure the back bonds to the now cushioned fitting such that it seals and does not vibrate.
I lay the speaker on it's face, remove the screws, clean the inset where the back resides, apply the gasketing along the bottom inside edges (no gaps), then re-install the newer screws/finish washers. I suggest doing this by hand (don't use power drills, you want to guide the new screws in) and do it in a fashion where you "tension them" in a half turn at a time once you get close, to seat the back evenly/gradually as you fasten it down (think auto lug nuts and "cross tightening).
BTW the Hillman screws came from Lowes in the blister packs, the stainless steel types. Take the old screws with you and match them up, even selecting a half inch longer version to assure the threads don't become loose. In extreme, worn out mount hole scenarios I've seen carpenters wood glue mixed with sawdust, then squeeze a bit in the old screw holes to fill the "wear out".
Now also in an ideal world you would do this AFTER any and all repairs, crossover work/replace, anything one plans to do inside the cab should be done, then seal them up for the next number of years.
If you might have the part # for those screws that might be very helpful. Cheers

I'm getting some air escaping from the backs of my 78 Cornwall I. Would you seal them with a window strip insulation, something else ?
Cheers

Hope everyone is well, been just listening mostly through covid here.
Do you think the kits will squeeze more out of 78" Cornwalls or will these always be a little more duller that say CWII's even when updated ? I just hate to get too bright having older ears.
Anyone tried crossgrading from Crites kits to the JEM btw ?

Starting a few of my smaller Cornwall I projects soon. Much of the Velcro on my Cornwall I/Grille's needs to be refreshed. Whats is the best way to go here ? Just carefully and simply re-glue the old stuff ? (In which case which glue is best to use ?), use new Velcro ? (if so, is there a good heavy duty Velcro on Amz to order ?), or is is better to switch to 3M Dual Lock or is this too secure and might damage the grille material when pulling off ? Thanks for any thoughts, advice.

Somehow I thought that "Decorators" did not have grills, or am I mistaken? Would like to hear from someone that actually knows the correct answer. Thanks.
Here is one of the tags if it helps with CD-BR I.D. I had someone tell me they were Decorator's so let see what comes up.
There is always the possibility someone painted the front's black and put Grille's on them ?

Hello,
I have a pair of recently acquired 78' Cornwall Birch Decorators that need a few things done this spring/summer and am wondering if the kind folks here can help.
- They came with mismatched tweeters so I am either looking for one K-77 (mine is stamped 82') or a pair of matched preferably square magnet ones.
- I am looking for small crimping forks like the ones used for speaker wire hookup to the B-2 Crossover. I need 4-8 if anyone has a few to spare.
- I have one cabinet that does not have complete factory speaker hookup wire from the woofer (prev owner used 14guage ofc speaker cable) and tweeter (factory wire been spliced and not well) to B-2 Crossover. If anyone has any spare factory hook up wire from this era please drop me a message. I can send a photo to match it up.
Please message me. I am semi retired. Much Obliged. Jim

I have several screws on my back panels of my newly acquired 78 ' Birch Cornwall I Decorators that go all the way in and are still turn/are loose. Is there a best way to fix these ?
Was thinking about using good wood filler applying with a toothpick in the holes, dry for 3 days, new pilot holes and new screws ?
Much obliged.

I missed you by a week. But good luck!

Moderna, both doses here, been over 3 weeks now. 2nd dose had a very sore arm fpr 2 days and a quick hot flash. Easy peasy.
Stay safe.

Wise decision. Why not just spend the next couple of months listening, move the chair around a bit, change the toe-in a bit, move them toward a corner or away from a corner a bit and just listen and listen some more.
They are good speakers. Enjoy them.
Thank you Tom, hearing from such trusted, long time members as yourself and others here since first posting has been inspiring and encouraging to say the least. What a incredibly, knowledgeable, helpful, and warm community! I'm most likely not to do any work until May or so tbh. Now back to listening to Dave Mason tonight 😉

Anyone have another zip cord source seeing the Home Depot stuff turns green ?
Also considering these after research and advice here, any opinions ?
