Have been looking for a sub for my setup. I have considered the Hsu VTF-2, several Velodynes (especially the CT-100), the Boston Acoustics 10" sub, The Earthquake subs, and now the Sunfire True or the Sunfire True jr. Anyone have any opinion on the sound quality of these units. The tiny size is very appealing (especially when compared to some of the bigger subs), but the price is pretty steep. I can spend the cash if they are worth it, but I don't know enough about them to tell.
