The simplest route is to try to repair them and replace parts with like for like. Once you change crossover parts things can get complicated, drivers even more so. Learn how to test the drive units for functionality, if they're faulty see if you can find reasonably priced (appropriate!) replacements.

If I remember correctly the tweeter was 'off the shelf' (dynaudio?) although discontinued now I suspect. The bass/mid drivers were made in house. I can't imagine the NAD causing grief unless faulty but what was the signal source?
Thanks, yes I am getting the impression that a major refit would be a professional job, I assume there are companies that can do this kind of restoration/upgrade.
Thanks, as I just posted I am thinking it will be beyond my limited knowledge, particularly if parts were specialised or discontinued.
I have a Marantz 7001 KI and a NAD 1020 also recapped/refurbished.
Thanks, I don't have a meter and wouldn't know how to use it, one of the speakers suddenly sounded very shrill/harsh/distorted at all but very lowest volume

Hello, another Richard here on a different quest. I have a pair of Winchester cabinets.. (and foam that likely needs to be replaced).. but no cross-overs or drivers. I have heard a pair many years ago and fell in "strong like" with them. Basically I have the wood with black veneer (not my favourite look, but I will address that once these are built).
So.. I wonder..
1. do you have any specifications regarding the drivers (so I can find/make a similar, other branded set) or even complete boxes
2. have you ever measured the individual drivers for the specs?
3. do you have a good picture or depiction of the crossover so I can begin with a decent start? (I've been checking the other croxxover meantioned in this thread for smaller Castle speakers.
I've looked at the Monacor 165 (somethings) so far, but wonder if the driver is as critical vs the cross-over and box. 25Hz seems quite low.. I know it is a blended sum of all parts, Honestly, I am simply looking for something more room filling, than my Castle Eden's which I love and use to this day. I want the warm, but with a bit more oomph in bigger spaces to not have to increase volume
Fun fact regarding the Eden's..... I have 3 pairs of them - two beautiful and perfect (bought new and nurtured) and one physically abused pair (that somehow still sound great) from Kijiji.
Thank you or anyone who can add any details to shorten my project

Hi Richard II, sorry but no to all of your questions. The mid\bass drivers were made in house by Castle, so unless you can find a former employee/engineer..
Good luck with your project

ok. Worth a shot. I wonder if anyone out there has tested the specs with magic math (stuff I don't understand... yet) or things like the DATS 3. Perhaps there are enough variables that I am best off finding a driver happiest in these huge cabinets and building from there.
Thanks for the response Nick.

A friend of mine in Italy and I put together a project with the Castle Winchester's 16 ohm woofers. We purchased them from a former Castle products distributor as surplus units. High Qt and Fs if I remember correctly. However, our cabinets were dual series bass reflex, not the Castle TQWT lineup.

Jusgt a box?
Gven the aspect ratio of the box, if just a box, it is an ML-TL, not a reflex.

INTERESTING Did they turn out well? they look great. Do you have the contact info for the supplier?
Thanks Mosquito!

No, it was a long time ago, but I remember that the volume is vertically divided 1/3 2/3, the smaller chamber connects to the larger part through a single round hole and the final (larger) volume is tuned by a duct. to the ground through the wheeled base that can be seen in the photo. Like this, but fh not ducted and fl facing the floor

Unfortunately that dealer close doors quite a few years ago. But any official distributor must carry spare parts as a normal deal with the factory. Maybe You can check that with the Canadian representative?

Fair enough.. I will see if I can find one.... and will also try Wimslough, Madisound, and Falcon. Failing this.. I may just "have to" buy four 6.5 drivers that I like the look of, and go from there. Having about 3.3 (quick math) cubic foot of air in these cabinets will be a challenge I am sure (for speaker damping/control).
If anyone has specific suggestions of which other speaker to look at, please let me know. Thank you all

These were very rigid suspension units with high Qts, 16 Ohm, keep this in mind when looking for suitable replacements. In the meantime, I asked my friend if he still has the Clio original measurement files. I'll let you know if he finds the data.

ah. Thank you for that hint and yes, VERY RIGID !!!
I assume that meant the drivers were originally wired in series (NOT parallel) so they would measure @ about 8 ohms. and then likely an 8 ohm-ish tweeter.
I've wondered if another avenue might be to perhaps find a suitable (but higher spec) single driver (to be front mounted) and simply "temporarily close" the up firing speaker hole (for now). I could then look at what I end up with before going further. I like simple.
I even wondered about a quality single 6.5 Coax driver (with tweeter in the centre). It is simply expensive to experiment this way. Any further info you have would be very appreciated. Thanks Mosquito!

BTW. I was not clear on your comment about High QTS, Most things I ~oogle.. mention that high QTS is best in a sealed enclosure, nd these boxes are neither sealed, nor small enough (I think) to provide much control on a driver (even with foams, etc). I am NOT an expert obviously. I then reread a couple links and found this, which aligns with your words/this scenario.
(Half way down this article there is a table with a few words following that fit the "large" size mentioned)
