I need help from experts about potential sonic problems with Cornwalls

A pair of Cornwalls for sale on ebay. The "dust caps" on the

woofers have holes in them. Sellers contends there is no sound

problem associated. My question to you experts is--can that be

trusted? Do the woofers need to be replaced? Will I be able

to pick up a "noise" as a result of these holes?

I am running Khorns for my fronts and I would like to add these

Cornwalls for rears and use Heresy's for center. I have always

gotten good advice from you guys; I need it now.

Thanks in advance.

I'd go better than a Heresy for center. A Belle Klipsch or La Scala would be a major

step up. IndyKlipschFan gets good results with a Cornwall for the

center, but even so I think one of the fully horn-loaded choices would

be better. The center is very important so don't scrimp there! Better

to shortchange the surrounds than the center.

Older Cornwall woofers may have a 1/2" hole in the dustcap with an open weave cloth screen behind it.

Later K33E have a 4-1/2" felt dustcap that breathes.

If you have an old damaged dustcap, the newer ones fit over the top and cost about $1 each.

Yes, I agree that looks like the screen vent in the dust cap is missing. It should not affect the sound and a replacement dust cap can be attached.

Those are pretty nice birch decorator type Cornwalls, fairly rare. There is some signs of water and sunlight damage to the tops, but the veneer looks to be in pretty good shape. I'd contact to see if you can get photos of the side panels and look for deep scratches or chips. If not, these could easily be refinished to their full glory.

In operational condition, these might go for $600-$1000 per pair. Please if you purchase them, PICK THEM UP PERSONALLY or arrange for personal transportation. These are too large and too heavy to be trusted to any freight carrier. If they are damaged in shipping, they cannot be replaced and you will be heartbroken.

Good luck with your purchase. I'd buy them myself but the drive is too far for even me.

You see this is why I posted the message; this was the kind of

information I needed. I am going to keep my eye on these

and see how it shakes itself out. I will keep you guys

posted. Can't begin to tell you how much I appreciate the

help. I am not an audiophile, but Klipsch speakers have been a

part of my system(s) since 1985. I have owned Khorns (this is my

second set; the first set called "bachelor speakers" by my wife were

sold, like so many, because my wife thought they were too big.

She relented last year, because we moved into a bigger house. I

bought a beautiful pair of 1964 Khorns), Belle's, Chorus, 5.5, 3.5.etc.

I am not a sophisticated audiophile, I just like clean,

and if I am inclined, loud music; remember they are "A Legend in

Sound".

Thank you very much. Any other advice people have to offer I am all ears.

i have to disagree with johnnyholiday, the woofers are probably not trash because of a dust cover, i would agree with michael !!!!!, i have had great success buying from ebay with many plug and play items for example my k-horns were from ebay and they are in what i would call a 9.8 on a scale of 1 thru 10, also my nakamichi rx 505 is a 9.9, my marantz model 2500 is a 9.5, my teak X1000R is a 9.0, all of which were plug and play and this is just a few items to make the point, and i bought all this gear at great prices couldnt have found it around here thats for sure just check there feedback, and trust your instincts Joe

Whats that on your scale,your dealing in fuzzy logic an so is

johnyholiday an that woofer has been abused, ,johnyholiday could care

less you disagree,an your 9.5 gear has no linkage what so ever, as

overflowed onto the Klipsch forum

Johny is correct, dirt, dust, fuzz, etc. can get in that hole and contaminate the voice coil and voice coil gap once it gets in it is ain't coming out. Count on buying two new woofers for sure since you don't know how long they have been that way add $260 to the cost for the woofers. Anyone that says otherwise don't know jack!

I knew a guy named Jack once, he was a good friend of mine, but he turned on me.

The screens in the dust caps could have been pushed in by tiny fingers. However, if they were very brittle, the chances are that the rest of the cone/surround/spider assembly could be brittle as well. The cones appear to have more than a little bleaching due to sun exposure. So while they might play and make music today, they could be prone to tears or other means of disintegration soon. So it could be a short life.

Regarding lint or debris in the voice coil gap, I'd say that any debris that could drift in there, including cone material itself, could cause overheating or shorting of the voice coil. I don't think anything light enought to get in there could damage the gap in the magnet itself though. If there is damage of any sort, I think the general consensus is to NOT recone the K33, but simply to purchase a new unit. The cost difference is negligible and you get less down time and more faith in a new unit.

That being said, if they work, they work. Why not just try em out? If you hear undistorted music, have new dust caps affixed and you're in business. If not, be prepared for the $260 expenditure.

As always, bid accordingly, from the wallet, not from your heart, although properly cared for, these are easily a pair of $1200 beauties in the waiting imho.

What did he say????

Johny, are you in some way making reference to my many Klispch purchases 'gear transactions'? Please translate into English before you light the pipe, man!

The Cornwall's I bought a few months ago had a torn dust cover.

They sound perfect when played, but there is a slight creaking noise

from the coil when it is moved by hand. I am sure there is dirt

in there, & it will be replaced as soon as I can afford.

Here is the link to the ones I found...... http://forums.klipsch.com/forums/522532/ShowPost.aspx

I'm glad you guys gave me the solid advice early into this thread,

because I have to tell you I no longer "speak the language" being used

here; I clearly am a novice.

Should I consider finding out--probably in the home theater forum--if

someone wants to split a pair of Cornwalls/Chorus for use as a center

channel speaker?

Ultimately, thanks for the great advice. Johny, great

stuff. I am going to make a point of continuing to read your

views--I want to learn your language.

Could

also be a slightly burnt voice coil and\ or dirt , think of the

millions

of cubic feet the cone has moved, an will move ,an how much air is

pumped over the pole piece for cooling, filtration of this air is

imperative, good luck with funding to expedite the driver retrofit
