The B2 Audio RIOT8P is an 8-inch pro-audio midrange driver built to cut through road noise with loud, forward vocals and instrument detail. With a 150-watt RMS rating, a 4-ohm single voice coil, and a UV-treated weatherproof paper cone, this pair is aimed at builders assembling a wall of pro-audio mids or upgrading a door and A-pillar setup that needs to keep up with subs. It handles the upper-bass and midrange band where the music lives, making it a strong fit for high-output car audio and sound-off installs.

Because these are dedicated midrange drivers, plan to run them off a high-pass crossover and pair them with a separate subwoofer for low bass and tweeters for the top end. The weatherproof cone treatment makes them well suited to door builds, kick panels, and open-air pods where sun and moisture exposure are a concern.
