I'm nearly ready to purchase a great greenback speaker or clone. I'd like to hear about your experiences with these speakers. I might buy the m and the h versions to include more bass options. Also I'm interested in remarks between the SA-12M-75 and the SA-12M-LHDC large dust cone version. Wow, I just checked out a test thread where Scumbag offered a blind test of these different speakers. I think I liked the Scumbag speakers the best, at least that was my top two picks, the H and M models.
