I have no knowledge or interest in home theater stuff but I did watch the FB video. I was curious how much the whole thing cost so I did a little digging. Here's the setup shown in the video:
Speakers
JTR Noesis 215RT (upright speakers) - 3,999$ x 2 = $7,998
JTR Captivator 40000ULF-ST (front subs) - $4,299 x 2 = $8,598
JTR Noesis 210HT ($1799) or 210RM ($2699) (center) - $2,699 (assuming it's the latter, the video isn't clear enough to distinguish what model it is)
JTR Captivator 2400 (rear subs) - $2999 x 2 = $5,998 (said to be "3200 Captivator" but there is no such model in JTR's product page)
JTR 110HT SL surrounds - 1,249$ x 12 = $14,988
Amps
D Sonic M3a-4500-3 - $3,275.00
D Sonic M3a-2800-7 - $3,275.00 x 2 = $6,550
Denon AVC-X8500H (£2,999.00) = $4,161.67
$54,267.67 x 48.36 = PhP 2,624,140.32
AVRs (servo motor)
Stavol ST-5kVA AVR x 2 (for front subwoofers) - PhP 8,399
Imarflex SED-5000S (3500W) AVR - PhP 19,000
TOTAL: PhP 2,651,539.32
Excludes other stuff like the projector since it wasn't mentioned in the video.
