You can boost the center channel (where dialogue lives) to make it more easily heard. Run it into a ribbon tweeter to make it easier to understand.
A simple compander adjusts the dynamic range to your liking.
Receiver Too Weak?
Below is my setup. It just sounds lackluster and I'm wondering if it's my receiver or something else. I put some links in there so it's easy to find specs.
Receiver: Yamaha RX-A770 (https://usa.yamaha.com/products/audio_visual/av_receivers_amps/rx-a770_u/specs.html#product-tabs)
Center: Bowers & Wilkins HTM62 (https://www.hifiengine.com/manual_library/bowers-and-wilkins/htm62.shtml)
Front: Bowers & Wilkins CM8 (https://hometheaterhifi.com/reviews/speaker/floor-standing/baw-cm8-bookshelf-speakers/)
Thanks!
