Rockville RM84PRO 8″ 4 Ohm SPL Competition Midrange Car Speaker, 108dB, 300w

By |July 23rd, 2026|

Car Audio & VideoPro AudioMarine AudioLighting Karaoke Home/Portable Audio Rockville RM84PRO 8" 300 Watts Peak /150 Watts RMS 4-Ohm SPL Competition Grade Midrange Car Speaker with 1.5" High Temperature Voice Coil and a Huge 100 Oz Magnet Structure --> Click Thumbnails to Enlarge Condition and Warranty Condition: BRAND NEW IN ORIGINAL PACKAGING Warranty: 1 YEAR AUDIOSAVINGS Product Description Video of RM84PRO: We are so convinced that these are the best midranges on the market that we will give you a 90 day money back guarantee on these. Try them for 90 days. If you don’t love them, then we will send a call tag for them and we will cover all return shipping costs and give you your money back in full. Rockville is committed to manufacturing products that represent “professional sound” and the RM Pro Series is no exception. Rockville engineers utilized the latest in Pro Audio technology and transferred it to these car audio midranges so that you will achieve stadium quality sound in your vehicle along with serious power handling. The RM Pro series is the step up high-end series of mids by Rockville. This 8” midrange/midbass driver features CEA rated 300 watts peak power and 150 watts RMS. Power these with an external amp for mind-blowing presence. The bonus of being a combination driver is the music still retains clear, crisp vocals without losing the lows of a song. You will be amazed at the definition, frequency response, and super high SPL that these speakers produce. Any custom installation won’t have to compromise on sound quality with the RM Pro Series. The mounting depth facilitates easy fit installations while never sacrificing quality for convenience. Extra care in the design and manufacturing are seen throughout with thoughtful touches. The cone and dust cap are Kevlar (the same material used in bullet proof vests) reinforced black pulp paper. The cone surround utilized a treated cloth accordion style to optimize control. The careful engineering involved prevents the speakers from blowing easily while smoothing out the frequency response. The result: increased sound quality at higher volume levels. The speakers have large 100 oz. magnet motor structures with oversized1.5" high temperature CCAR voice coils. The expanded high tinsel steel basket dampen vibration so that all you hear is crystal clear musical response without any external motor or vibration noises. Unlike other brands, which produce their speakers by machine, the RM Pro Series speakers are hand made individually by technical teams dedicated to perfection and are subject to rigorous quality control standards. Keeping within the industry standard, these speakers are CEA compliant, which means they are tested and rated the same way that other premium brands such as Kicker, Rockford, and JBL rate their speakers. So you can feel confidant when comparing these with other midranges on the market or when matching these up with a high quality amplifier. This ensures Rockville products aren’t the subject of bogus claims or inflated specs. We have seen midranges labeled as 600 watts that really cannot even handle 100 watts. Our speakers are 100 times better sounding than the competition, and can handle way more power too. When we manufactured these, we aimed at creating a better sounding mid than any other brand on the market for a fraction of the price. After testing our first production samples we knew we achieved our goals. We are so convinced that these are the best midranges on the market that we will give you a 90 day money back guarantee on these. Try them for 90 days. If you don’t love them, then we will send a call tag for them and we will cover all return shipping costs and give you your money back in full. Typical vehicles are missing loud, clear midrange/mid bass response, but now with Rockville you can experience music the way it was meant to be listened to...loud and clear, with a full range of frequencies!
