I have a few downloads from the Media section that I consider reference audio-video material. They are short and sweet with great wow factor.
Hoping to get this into a sticky if enough people like the idea. Here are a few to get the list going (all in 1080 version):
1) 30 Days of Night Trailer (sub workout like none other)
2) Incubus BD Promo (excellent PQ/SQ and a good song)
3) VT6 Game Trailer (sub workout and good surrounds use)
4) Wipeout Game Trailer (good PQ/SQ and excellent center clannel use)
