Some difference I can comment on. The Wet Sounds rings are cast poured and have a "frosted" look. The bullets are polished clear. This will allow each individual LED to be seen. Also, the strips used by Wet Sounds are 600 LEDs per 16ft roll and th last set of bullet rings I saw used 300 LEDs p/ft strips. The Wet Sounds kit has you attaching the LED strip to the inside lip of the speaker, then the ring goes on over it. This has the LEDs illuminating the ring. The Bullets state that the strip is glued to the ring. Not sure how that effects the lighting.
