That is not what I am saying. I am saying that I listen to normal dialogue in the 60-65db range typically. That does not account for peaks which could probably reach close to the 85-90db range when listening at normal dialogue levels. And there are some big differences between speakers that have the same sensitivity ratings at that 75db and lower range
I will take some SPL measurements tonight when I watch a movie (I have a couple of Blu-Ray's that I was planning on watching anyway) to see what I normally listen at and will try adjusting up by a good 5-10dbs from normal and will see where peaks are at. I will try and compare a heavy dialogue driven movie vs an action popcorn movie.
I do appreciate your comments. I think you raise some interesting points that I will definitely ponder and research more with regards to speaker design.
I just find it interesting that the majority of bookshelf speakers that I personally gravitate to tend to have a sensitivity rating of 87-89dbs, and those speakers that get highly rated by various users and professional review sites that fall in the $1K and under range (per pair). Examples of speakers that I have listened to very recently are:
- NHT Classic 3
- PSB Image 25
- SVS SCS-01
- Paradigm Mini Monitor
- KEF iq3
- Aperion Intimus 5B
- RBH MC-6C, 616C, RBH 61/SE-R
Speakers that I have not heard that get great reviews:
- Emotiva ERT/ERM series
- Ascend Sierras
- Ascend CBM-170
- Axiom M2, M3, and M22 speakers
- Aperion Intimus 4b and 6b
- Swan bookshelves
, etc, etc,
None of the above speakers are rated above 89db's.
As for HT custom installers I can tell you for a fact that a well known company in the Salt Lake area pushes many RBH spekers that are rated 89dbs. And custom installers are not (from what I have seen) going to push internet direct company speakers.
