Greetings everyone on this Friday afternoon, I am looking for some help as I learn to read measurements. How would I read this graph and what does it say about the speaker tested? Trying to decide if my hearing is hearing good things of a bad speaker or is this a good speaker? example: Where is the roll off? I thought it should be smooth as example? The three different colors represent the 3 different placements of the speakers in the room. Thanx!

Measurements are form here: https://www.audioholics.com/tower-s...The JBL ES80 didn't,on the Klipsch doing this.

It's an in-room frequency response measurement, so says more about the room than the speakers.

You can still get a rough idea of the speaker's bass- and treble extension from that graph, but overall, it's of remarkably little use for judging the speaker itself.
