Upgraded the stock speakers with the Flipper Fidelity coax system. Normally, I hear an immediate improvement when I first change out the back box speakers . I did not notice much and was a little concerned. I then changed out the cabinet speaker, adjusted the speech to a setting of "8", and the music to a setting of "25". Significant improvement!!! As stated earlier this pin has a lot of cool sounds that get brought out with the quieter music, sound and better speakers

Thanks for the tip. Went into "Utilities" and adjusted both the Bass and Treble. I need to tweek a little more but the Bass really came out even more. Another significant improvement! The FF coax speaker set does not have a cross overs for the cabinet speaker but with the bass turned up a little you do not need the cross over in my opinion.

If you have not tried tuning the sound in this game you are missing out with or with out speaker replacement or an external sub. The music and speech blend with the game sounds so lowering both helps the experience greatly.
