There’s only so many manufacturers of speaker drivers, at least in commercial quantities. So you’re going to see a lot of similarities for the physical side of the speaker. But there are definitely still differences.
For example; compression drivers have a very lightweight diaphragm, so they’re usually considered to be very detailed, open and airy. Because they have very little mass in the actual diaphragm, they can respond incredibly quickly. This means they have really good transients in terms of the way they deliver sound, but if I move across to air mass transducer, or a ribbon tweeter for lack of a better word, they’re also able to move extremely quickly and provide really excellent transients even though there’s complete differences between the two ways they operate.
If you think about the word compression, it’s actually compressing the air and firing at you, and so you tend to have a much more physical response to the sound that’s coming at you.
Whereas there are other types that are actually vibrating the air in front of you, and it’s a much bigger soundstage, which makes it much easier to listen to the sound they are producing. Depending on the speaker it might produce more ‘wow’ factor and others might be better at more relaxing sounds.
