Hi, I have both a sunfire and velodyne hgs-12. I was just using a sunfire for both HT and music but did not sound right, in fact my HT system was not the best system for music. I listen to music more than Ht. I had to build a seperate system for music (kids and wife have taken over my living room and wanted a good music system)and I have tried the sunfire with my music system, I do not like the sunfire for music, It's a great HT sub but it was just not a musical sub, I could not get it to blend in and it overpowered my totem model 1 monitors no matter where I placed it. I bought a used velodyne hgs-12 for music and that sounded a better and more musical than the sunfire. it blended in better and kept up with my monitors and it was not overpowering. The velodyne would have made a decent HT sub, but the sunfire seem louder and more powerfull(great for HT). if I was to have one system is would the sub choice would be velodyne because of the music but, for HT the sunfire fills my 18 x 20 foot room with explosions and loud deep bass in HT. hoped This helped
