What is your take on high efficient speakers vs. low efficient speakers?

We are all basing our opinions and experiences using " reproduced / recorded " music. As I have said many times, this alone, creates many challenges for us as listeners. It boils down to the specifics of what YOU want your favorite performers to sound like, in your own listening room.

@mrdecibel No, we're not all basing our opinions that way! In my case I base my opinions on having been at the recording session, have the master tapes and know exactly how they are supposed to sound.

So are I've yet to hear a lower efficiency speaker that brings out the dynamic character properly in these recordings. Not saying its not out there, but clearly such a beast is in a dramatic minority.

^^ Yes. The difference between sensitivity and efficiency specs is poorly understood. You have to do math to convert from one to the other unless the speaker impedance is 8 Ohms.

The question: what is high sensitivity? Yes I agree. For real high sensitivity let say 98dB and up it is an issue.

My Classic Audio Loudspeakers are 98dB and flat to 20Hz. They employ dual 15" woofers as well as field coils to reduce distortion and compression while increasing speed.

I have a standing wave in the room that prevents bass impact at the listening chair. This issue was solved by the addition of a pair of Swarm subs asymmetrically placed in the room. I didn't run 4 subs because the main speakers go as low or lower than most subs. I used the Swarm subs because they are designed to be placed directly against the wall, inside the room boundary effect. This allows them to be more compact and out of the way; they are flat to 20Hz as well but not nearly as efficient, each using a single 10" driver. No troubles in the blend department though. No troubles with the WAF either :)
