I ordered an HTC to use with my HT3's but it hasn't been built yet. I would have preferred the HT1 for a center channel but it was too tall to fit under my screen. I'm glad the HTC matches up well with the HT3 as this is my primary concern. For music, I will run my HT3's large but for movies I will probably cross them over with the HTC (possibly as high as 80hz). I'll post after everything arrives and is set up. It shouldn't be too long now for the HT3's.
