I have a Mesa TA-15 with a 1x12 cab loaded with a G12H30 Anniversary speaker. I'm looking to replace the speaker because although I like it's bass and clarity, the high end gets shrill and it's loud. Looking for something articulate but warmer with less sensitivity. I have a different amp for Fender clean platform + pedals. The TA15 is my plug straight in for Marshalll, Vox and Mesa slight dirt to distorted tones. Any thoughts on these G12M speakers in this amp?
