The この refers to サウンド. The basic structure of this sentence is 「何だ、このサウンドは？」
(= Inversion of 「このサウンドは何だ？」, "What is this sound?")  
The に is an indirect object marker. 響く is an intransitive verb and can take an
indirect object.

「サウンドが心に響く」 = _lit._ "A sound resounds/echos through one's heart" → "A
sound/tune/music resonates with / touches one's heart"

So I think your translation is good.

> 「何だこの中二心に響くサウンドは（？）」  
>  "What is this sound/tune/music that resonates with / touches my chuuni
> heart?"  
>  (... with a nuance of exclamatory "What a (touching) sound/tune/music this
> is!")
