Dalesford Drivers


Does anyone know anything about Dalesford drivers (made in England)? I stripped them from a pair of DIY transmission subwoofers that I had and want to know if they are worth holding on to.

Thanks for the responses. They are 10" woofers with a 6" magnets. It appears to be a Feroba II magnet.

I was looking more online and the drivers appear to be similar to what was used in a Fried Model T subwoofer.
If you can tell me the model number, I can, likely, tell you the specs.

What brand t-line speaker kit are they from? Fried used these in Model T.D and O. Are the voice coils 33mm or 55mm, plastic or cloth dust caps? I see that Kal knows about these drivers also. I would like to know the specs Kal has compared to what I have been told about the driver parameters many years ago. Most people never heard of this company. The oem units Fried used were the best bextrene cones. I had to reglue surrounds to driver frame over the years.
I have a catalog from England that lists (and pictures) the drivers with summary specs for each model. There are, also, similar tabular listings with similar info. All are Bextrene cones but the v.c. diameters vary.

Does the catalog show one D153 and D250 model? The D153 stock version had a 93mm magnet and the Fried version had 102mm magnet. The Fried version was 93mm deep, stock was 83mm deep. The Fried version back plate to top plate depth was 37 mm deep compared to 28mm for stock D153. I wish I could see the catalog.
