Hmmmm weird, while I would assume the revolt would have better sound compared to the nightstalker/outlaw due to the tweeter. The horn speakers are probably the same or very similar.
I don't know how much it matters in terms of volume and/or clarity but when playing the same sound I didn't really notice a difference. Although my outlaw is using li-ion pack that I made, maybe that has something to do with it...?
To be honest my shockwave has a more noticeable clarity/quality difference compared to the revolt or the outlaw. To be fair I only played a few sounds on the revolt and didn't really care for the remote, which is why I sold it. My Ouytlaw was a pinch louder, similar quality of sound, better battery life, and I liked the remote layout better.
I'm wanting to play with that new super revolt though.
