I built some tri-trix mtmtl from parts express and using pioneer HT to power them. Optic signal from ps3 as the source. I hear new things in songs I listened to my whole life for the first time since building them. On some tracks the direction of the singers head can be distinguished, placement of the band and sound stage of unimaginable separation. Great budget setup that kills bose systems.
I'd say I enjoy my home system more than my car, and it was way less money. I've since built 3 more sets of speakers and all were equally impressive. Surround sound music isn't for me, I prefer 2.1 or stereo with full range horns for acoustical music.
I pretty much gave up on DL music, cd quality is where its at. If this format is comparable then it's worth a shot. Thanks for sharing this!
