The GT2450 on paper looks bad yes.. But they work VERY well.
I run them on GTRs and on 2ls also (1x on 2l ;)
I use the GT25s with the TO4S comp and 0.7 cover.. Very mismatched on paper,
but excelent result.
I know of a couple of people who have been disappointed with the 2530s and
now which they had gone to 2540 or eqiv.
