- I had a 30 year old pair of Magnat speakers that still performed very well - I had the foam surrounds replaced and the crossovers rebuilt and they sounded even better than when they were new.
I’ve since replaced them with a speaker that uses current design approaches and more modern drivers/technology - and yes, they do sound better.
The reason I started looking for replacements, is that on such old speakers, something will eventually give. When that happens, you no longer have anything to compare the new speakers to.
So while they were still working I replaced them by comparing the old sound to the new.
The new speakers are a three way design - like the old, and present a very similar full sound..
The new speakers provided benefits in the areas of...
- improved dynamic performance and clarity
- much improved imaging
- improved bass performance - i.e. control, detail and depth
So I am very happy with my upgrade.
But some of the older gear does have certain advantages - looking up your 150’s on the web - one review stated you can listen to very loud music before distortion becomes an issue - something few speakers new or old can do.
I traded my old speakers to a guy that loves antique gear - he’s very happy
Hope that helps - Steve
