I've had my Klipsch speakers for over 20 years and have always used Cinema EQ...works for me in my system.
I also have Klipsch speakers, which are fairly bright to begin with (but good, and with great dynamic capability and very clean, precise sounding transient response). With modern
movies on Blu-ray, they sound very good with Audyssey Flat, and even better with Audyssey Reference (i.e., with Audyssey's midrange correction and moderate high frequency roll off). I almost never use DEQ, and almost always run movies about 3 to 5 dB below Audyssey determined Reference Level. The movies sound very dynamic and exciting, with strong, sometimes overwhelming, bass.
Now with older
movies of the magnetic Hi Fi Stereo era
(certain, but not all, movies after 1953, especially 70 mm movies) it's a different story. IMO, the people who transfer these to Blu-ray often do not use anything near the bass EQ the studios used to use in preparing release prints. During the original recording sessions, great care was taken not to over-record, so some bass roll off was often used both in the boards, and at the microphone roll off switches. When the final mix was made, when it was less expensive to try over and over again to get it just right (since musicians and sound effects guys were not sitting there being paid during the mix down), the bass was restored, sometimes boosted even more, and the dynamics fine tuned. Even though theater systems typically started to roll off below 40 Hz, some very dramatic bass (about 40 to 200 Hz) found its way to the theater audiences, if they were lucky enough to be hearing a magnetic soundtrack. When Blu-rays are made from these old soundtracks they understandably try to go back to the original, first generation, magnetic sound elements -- which have rolled off bass -- but I strongly suspect they fail to put the bass back, perhaps because they are too young to know what these films sounded like in the theaters. The latter may sound far-fetched, but the BD supervisors are the guys who allowed the resolution of the faces in Patton
to be softened, and had to do a new transfer when the complaints came in. If they can do that to the image, there's no telling what they might do to the sound. So, for films of that era, I turn up the bass, when I can. DEQ doesn't seem to solve the problem for me, so I use other means. The sub is easy to turn up, but that stops helping somewhere above 80 Hz. My pre-pro tone controls (not virtual sliders) allow me to turn up the bass by about 6 dB. Since Audyssey actually cuts the bass down a little in my room, with my speakers, with these magnetic era movies only
, I sometimes turn Audyssey off.
