Five screen matrix - JBL 4673A - cheap as fish and chips with a huge cinematic sound!
Little bits of cardboard stuck between HF horns to keep the sound from passing in-between the voids.
The far left side needs to have false wall that meets the chimney breast, the left side is bit of void that I want to get corrected in june.
I placed foam tiles on the speakers baffle as they mostly act like a baffle wall with side by side coupling. I didn't take a final picture with foam tiles glued to the speakers to prevent high frequencies reflecting from the HF horns onto the screen surface while still passing sound though the screen and the reflections, reflecting onto the bare surfaces of the JBL bass cabs.
The screen speakers position will be adjusted around early june, by lowering the stage speakers down by 8". I should have done this earlier in the year, but was pressed for time and nothing wrong with the positions they just bit too high up for the HF horns that and horns directivity sound I can still hear sound frequncuies from movies or music or using test tones with REW with filtered pink noise being narrowed to play the higher pink noise or widen the range out for full-bandwidth pink noise, or use sine wave tones or repeated frequency sweeps.
I can hear the sound pans move smoothly across the screen. (The little lady talking on the phone) in Die Hard 2, is heard in right-centre when using five screen matrix, with regular three screen I hear the voice in centre with a half pan to right stage channel.
In the video the sound drops out on the Dolby AC-3 due to using RCA cable that is prone to picking up electrical mains light being switched On/Off or other such as maybe EMI/RF interference. The cable will be replaced with a cheap fish and chips optical cable that has the same, bit for bit data only passses it though with optical light and will keep the Laserdisc AC-3 signal stable. I use optical for dts as that is usually required since the dts is on the PCM track and passes through the optical output on the Laserdisc player.
I rarely switch the laser projector On, mostly use the Oled 65" sure I can get a 85" Oled but the prices are daylight robbery, more than the projector yet, the projector is still the Original can still project a larger image and far thinner cos it is just light image shining onto a projection screen that is still to this day far thinner than any Oled.
I saw Die Hard 2, first at the odeon Cinerama screen 1 with Dolby Stereo A-type and the original Overhead surrounds in the ceiling.
Listening in middle of course made the sound from the screen sound a fraction narrower but still wide LCR. When sat front and centre row the sound image is far wider and the surrounds a little distant but same with real life sound hearing someone talking to you, within few feet and someone else yelling out to you, or myself at distance of 80 feet.
Second time around seeing Die Hard 2, in Dolby Stereo SR at UCI tower park in one of the smaller screens with Overhead surrounds (still have the ticket) maybe I can find out which screen number not that matters as all the smaller screens was identical same as the two larger screens being identical.
The sound in the smaller screens sounded narrow or smallish when sat middle I can still detect panned screen sounds across the LCR. The screen height is sort similar to my small room with screen going from sidewall to sidewall and the screen channels thou bit tighter closer together in my room as the small UCI screen is still I think about 35 feet wide horizontally looking at the seating that is usually 24" and gaps between the seats and the aisle. My front wall for the screen is only 9 feet 2 inches.
