That's right NSD! I got a 2nd hand Celestion G12M-65 Creamback today, should have it in a day or so in the mail. The real fun will be designing a 1x12 cab for my SV20H, I looked at the SV cab and the 1912, both have slightly different dimensions and are designed slightly different so it should be fun experimenting with the different features to come up with something that sounds good to me. The main differences are the 1912 is MDF and ported in the front with a closed back, the SV is all ply with an open back. If anybody has these cabs I'd appreciate you weighing in and tell me what you like or dislike about your cabs.
