Question [Q] speaker quality resurrection remix

Hi,

I just flashed Resurrection remix and i love it!! I just got one issue i can't find a solution for. The quality of the speaker isn't nearly as good as it was on the stock 4.3 tw rom (with voodoo sound mod). I've already tried the voodoo sound mod, boeffla sound engine, and viper4android (which is really impressive) but non come close to 4.3 stock.
Does anybody know how to solve it ? Or is this just 4.4 related ?
