Passive radiator


Were passive radiators an ultimate failure? Does any speaker company still use them? A friend of mine is asking about them in regard to vintage speakers, and all I remember is being unimpressed. But I don't want to tell him that without some back-up.

What is the point and the result of plugging the port on a bass reflex system which some manufacturers have suggested is an option?
Some prefer less bass from their systems. With a rear-firing port; wall proximity can become an issue as well. I used to provide a couple pieces of bonded Dacron, with my vented systems, so customers could adjust to their tastes.
