I am confused about the bass boxes. I thought that the 2-12 box was called the TL-4050 and the 2-15 box(Wbin/folded horn was the TL-5050. I will have to check my archives when I am home. Anyway, I just bought four of the SM120A's from an estate. The previous owner used two EV sentry IVB systems in his house for his hi fi. Two SM120A's per side.. One used an 1823 and the other an 1824. I thought that was unusual. I am interested in how they will sound, but I will be trying out EV 1823's with them.
