I sometimes use 218 sub 4 + 4 st 110 for students galas and I have reconnatre that even if the system is ag is still very apprciable for such prestas many more that the MT 2 !!! The ST 110 heads are small and if properly proc rules with a digital, they are not aggressive ... The system is "franc collar" it wears away, it ' is net! Like it or not but I, who love the sound rather round and mellow, yet I appreciates his punch and his shot!
A good system but Avoid to filter with a simple crossover because it draws in very good results by working with a digital proc. Better than alpha E o MT2 at least in a weight / power / space ...!
