Hi guys I finally renovated my living room after 1 months i want to install ceiling speakers as the space is limited x4 in each corner of the room. Room 4.5m by 5m. With tv and siting position in the one corner. What sort of speakers would i need ? I currently got Dali Epicon 2 in my music room and looking for 70% of the sound quality . Also what sound compromise would I be making for having speakers in each corner of the room and sub vs regular stereo with sub. Unfortunately I don't have enough depth to put in walls Many thanks
