I have been considering getting a different cone for the Mark IV Combo.
The C90 sounds good for most low level playing, it is awesome with a dry tone for the clean channel. However, it just sounds awful with RHY2 or Lead when the volume gets elevated. On the other hand, the Mark IV sounds perfect through the 412 cab that I use with the Mark V. I have been considering getting another 412, but empty. I will select the drivers that meet my style. I did try one of the V30's I pulled from the cabinet in favor of EVM12L. Yes I did have an EVM12L in the Mark IV for a short while. The basket and large magnet made for a poor fit in the Combo due to mounting position. Not sure that would have made a difference but it sounded really good. I read (in this forum or a different forum) someone's liking to Fane relating to Hiwatt cabinets. Checked them out. The AXA Studio 12L is comparable to EVM in design but with an angled basket (more like the C90 but not leakage prone steel). Magnet shape is similar to the V30 (thicker and not as large in diameter as the EV). My hopes is that it will fit without touching the power tubes like the case with the EVM. Since the mounting ring is different on the Fane frame than the EV, I may be able to mount the speaker from the front of the cabinet without having to modify the grill (I just ordered it today). Cost for the Fane is about the same for EVM12L.
I had considered Eminence (Commonwealth in the patriot series) but decided to go in a different direction.
