Planning a home theater? Design the whole room in 3D — free.
Room Design puts every decision in one place: the seats and the platforms they stand on, the screen, the projector, every speaker and the subwoofers. Change one thing and the rest follows — make the screen bigger and the front speakers move; move a row and every angle is checked again.
✔ Every seat checked against CEDIA/CTA-RP22, the industry's recommended practice for home theaters
✔ Dolby Atmos, DTS:X and Auro-3D layouts, from stereo up to 9.x.6 and beyond
✔ Sight lines for every row, upright and reclined
✔ Projector placement, lens shift and real on-screen brightness
✔ Subwoofer placement compared seat to seat
✔ A printable report, and one link that holds the whole design
No account, nothing to install.
To show what it can do, we designed a room that reaches RP22 Level 4 for its speaker layout — the highest level — with six recliners, a 160″ screen, 19 speakers and six subwoofers. Open it and change anything (link in the comments).
