DENON AVR-4520CI 11.2 Surround Set Up
I am upgrading my Home Theater system from 1080p to 4K.
HT Room : 5m x 8m dedicated HT Room.
A/V Receiver : DENON AVR-4520CI. 11.2 surround capability.
Current Speakers : 7.2 system. 7 speakers and 2 subwoofers.
Projector : Sony VPL-VW1100ES 4K.
Screen : 150" EluneVision 4K Reference, 16:9, 2.40 gain.
I am thinking to upgrade the 7.2 speakers system to more speakers set up.
To have full 11.2 surround capability of Denon, I need to add another 4 speakers at front screen, namely 2 WIDE front speakers and 2 High front speakers.
For additional 2 Front WIDE Speakers: I cannot do this due to room width limitation.
For additional 2 Front HIGH Speakers: I can add this by hanging the speakers high up with the ceiling mount.
I need some advices:
Do the additional 2 Front HIGH Speakers (9.2 system) give a much better surround sound than my current 7.2 system ?
Worth to do the set up? For cost I do not need to buy extra speakers as I have 2 spare speakers available, only need to buy one pair of Speaker Mounting brackets (small investment).
All advices and recommendation are much appreciated.
