I HATE this freaking forum, I HAD a post that took me 1/2 an hour to type, and LOST the post, trying to tag the gad dang thing!

I bought these Cornwall 2's locally here in Tampa from a man who bought them from Betty, on this forum.

I want to  get inside them to check connections, replace caps, etc, etc.

Any idea how to get at the crossover, and anyone have a schmatic of this crossover, soo I can order caps from Madisound ?

DJK is right, these are good seakers, FAR better IMHO, to the 2 sets of Cornwall 1's I have owned.

DJK was right about the original Forte's too, a great speaker, for the money, just too small for my tastes/room.

 Get ahold of member

Bob is a great guy.

I just need a cornwall II crossover schematic to get the parts values, I just might have the needed caps already ?

I wonder what other tweaks Cornwall 2 owners have done ?

I think the midrange horn is plastic ?

In that case, it shuold not need rope caulk ?

 Rope caulk is a wifes tale..................Not Needed .

Yeah, especially on plastic horns.

More interested in crossover parts upgrades, and to do what I think DJK said to do.

I have to check the old thread, but I recall him saying to solder the wires directly to the drivers/crossover that use push on connectors ?

Maybe there are some more Cornwall 2 Tweaks/Mods that make good sense ?

I have owned 2 pairs of Cornwall 1's.

DJK is right about the Cornwall 2, it is a much improved speaker IMHO then the Cornwall 1.

 I was up till 3 am last night listening to the Cornwall 2's.

Can't wait to get inside them, and update the crossovers, if I only had a schematic .....

Thanks Bob !

The woofer cap, is that 68 mfd, or 6.8 ?

 Picture of the early Cornwall II gnarly crossover before they had them built on a circuit board.  Burn on the edge by cigarette or soldering iron may have been an added option.

Thanks Bob !

Those look like Mylar Caps ?

If they are Mylar, I would not think they would be Bad ?

I have never measured a bad Mylar capacitor, unless it was blown up.

They seem to age well ?

Many Mylar Caps are pretty high in ESR, if I recall ?

The reason I am asking this Bob is because the tweeters in my Cornwall 2's seem a little slow, or sluggish sounding.

Perhaps the diapragms are aging, and replacing them will be a better course of action then replacing Mylar Caps that are most likely still good.

What is your experience with refurbishing Cornwall 2's Bob ?

What do you see your Cornwalls II customers doing ?

Most of my customers completely replace that crossover.  Some rebuild it on the same board using lots better caps than those on the board.  And most of those cheap little blue caps test pretty bad by now for ESR at least.  

 Most also opt for the titanium tweeter diaphragms to liven up the tweeters.  They are smoother and extend higher.

Ok, that was allI was waiting to hear Bob !

I see on the Cornwall II Tweeter K 79 Titanium Diapraghms on Ebay from you.

But before I buy them, what about the K 52 midrange diapraghms Bob.

Do you think they are OK, or are there upgrades there too

Forgot to ask you WHY you dont use the felt damping pad under the new titanium diapraghms for the Cornwall 2 K 79 driver Bob ?

Just wondered ?

Bob, WHY would one replace the whole crossovers ?

I mean inductors dont go bad, right ?

Why NOT replace just the Caps, am I missing something ?

No upgrade to the midrange yet.  I have so far had two different prototype titanium diaphragms made for that midrange and have rejected both of those samples.
