Tips & Tricks:
Don’t try restoring the old original speakers. I did. There 50 years old and didn’t sound that good Cost me a lot of money to try, and ended selling them on Ebay for a loss.
They sound great. Cabinets weight a ton and the are bullet proof. They can really thump.
About the Designer:
Retired and know enough to be dangerous.

These look great, and I’ll bet they sound even better. The old real wood cabinets that new speakers rarely, if ever, have are my favorites. I have something similar I’ve had on my “to do” list since I retired. This inspires me to get them done! I wish build details were available, especially the front panel routing.
Those cabnits are cs-88… the cs-88a speakers are 6way speakers mate
These are some nice speakers to update, not sure why people just cant admire and commend instead of always trying to correct, but any way you gave me some incentive to do some rebuilds. Nice Job!
these are the CS88 speakers. The 88A contained 6 elements. 1 woofer, 2 mid range 2 tweeters and 1 super tweeter.
I have the CS88 s as well. I could do this speaker upgrade but I can’t solder caps. Not my thing. So……not sure a speaker exchange would really work. My old 50 year old paper cones are not great at this point.
These were made from CS-88a Cabinets.
I’m working on a pair of Wharfedale’s W90D’s now.
