Why is it that there is no Harman products (full range speakers) that are designed to go flat to 20Hz (3db down at 20Hz anechoic)
I understand that a 3 cu ft speaker designed to go flat to 20Hz would have a low sensitivity (maybe 84 db). I also understand that JBL (Harman group) has a reputation for high sensitivity systems. And people have the option to utilize a sub woofer for low frequency extension.
With all of that said, why is it that there is no products (full range speakers) that are designed to go flat to 20Hz?
The only 2 possible answers that came to mind is:
1. There isn’t much demand for this type of product
2. It is extremely difficult to engineer
Any thoughts why it is difficult to find such a product? I am assuming that it would be attractive to at least some people.
PS: I am referring to a consumer type passive speaker (speakers with no internal amp, no DSP etc). I also realize that “in room response” of many speakers will measure down to 20Hz but I am looking for anechoic response to 20Hz.
PSS: If it would be more appropriate for me to post this in a different forum (sub group) let me know. I am a newbie
