I just got my tone tubbies today. I ordered one alnico and one ceramic. both hempcones. I talked to the guys at a broun sound and they said that for a closed back, the ceramic would be better, so i installed that in my randall iso-cab, which is normally only so-so. previously to this i have tried a v30, a greenback, and a bad cat labeled speaker (a modified v30?). out of those i liked the bad cat the best. but at high power into the iso cab, i think the bad cat was a little overworked. the bad cat is loud when the master is at 2o clock and the level is at 1 o clock. (great bedroom volumes). so this speaker doesnt flub, fart, cry, distort, or anything else bad at those volumes. its super smooth sounding just like i like. i can tell already once this gets broken in it's going to be great. it is a bit louder than the bad cat speaker. i am going to be selling the bad cat 12" since i like this soo much. the alnico tone tubby is going to go in 1/2 of the bad cat 2x12 cab i have. I have a feeling i like these so much im going to try to find another bad cat cab and run what tone tubby calls the "bomb" setup, 1 hemp alnico and 1 hemp ceramic. all in all im satisfied even though this is still the honeymoon phase.
