Hi every body. I woundered if anybody would be kind enough to do a driver frequency simulation for me for a mt121. This would be a massive help and i would be very grateful!! I already own 2x fane sovreign pro 12-500's and i am planning on building a pair of mt121's. I currently have no comp drivers in mind. I just want to know if these drivers are suitable for said cab?
I know its a bit cheeky but it would be very helpfull if some one helped out.
Thanks,
Tony
