The new Cicada Audio CM8.4 speakers are a great solution for 2014 and later Harley baggers. But…these speakers are NOT an easy fit into most bags.  Typically, the bags are designed for 5 x 7’s (sometimes 6 X 8’s) and NOT 8 inch ROUND speakers.  Just so you know… These DO NOT simply bolt into the factory speaker locations (typically an adaptor is needed, or built).  This is REALLY for Professional Installers to install.  DO NOT grind on the frame to make it fit!  That VOIDS the warranty.  Why would we tell you this?  Because we want your business.  1,000 of this size frame 8 inch framed speakers have been sold for Harley Baggers….  But no one has ever told anyone what REALLY is going on.  We will ALWAYS tell you the truth.  No matter how painful.   Great speaker you need to work a little to mount.  That’s all. (again……Time to get a PROFESSIONAL to install this speaker – HIGHLY RECOMMEDED!!)


Cicada Audio was started to develop and sell product… SPECIFICALLY for Harley-Davidsons. Even though you’ve probably never heard of Cicada Audio…. our president and head engineer, Larry. has been designing 12V audio for over 30 years.  He has 5 design and engineering awards and 2 design patents.  He’s developed 1,000’s of products in that time many gaining “cult” status. He REALLY knows 12-volt audio.  He saw that there was a real need for some new thinking and new direction in audio.  Specifically, “motorcycle audio”.  We, at Cicada Audio, don’t do “car” audio, we don’t do “marine” audio, we don’t do “powersport” audio.  We ONLY do Harley Davidson™ audio …PERIOD!@!!

These drivers handle more power, are louder, play lower, with more authority and sound better right out of the box than any other pro audio type speaker for Harley applications. We’ve built these speakers with the best materials we can use and keep sensitivity and sound quality as high as possible. With 2-inch voice coils on the MidBass driver we’ve built in extreme sensitivity for unreal output and high heat dissipation. Light weight neodymium magnets, high sensitivity, cast frame, trick dust cap to improve sound, these speakers are way beyond all the competition.   Pair these with our Ring Radiator Horn tweeters (RR1T or the super shallow RR075T) and you have a winning combination.

The cone materials, surround and Powder Coat finishes have passed extensive UV exposure testing to ensure these speakers will look and sound amazing for years to come.  Yes, they are paper cones. So you have to think…”Why” would Cicada Audio use treated paper?  They could have used Carbon Fiber, Kevlar, Polypropylene, any number of “cooler” materials.  Great that you asked!  It is because we STILL have not found a better sounding…OR as light a material as paper.  And the weight of the cone changes EVERYTHING.  Remember that Larry has done this for a few days (over 40 yrs.) and has seen it ALL.  Been there, done that, filmed the movie, wrote the book, printed the T-Shirt!  He didn’t do it because it was easy.  He did it because it is the best for sound AND sensitivity.  You have to ALWAYS think….or remind yourself, that ENERGY isn’t FREE!  And your bike can ONLY produce so much energy.  PERIOD.  To make power….you need power.  Seriously… you have a 50-amp stator on your bike!  For every 1,000 watts you need 116 amps of current (Full Range Class D!)  Larry teaches BE smart, design around your bikes limits and get the MOST you can out of your system ..WITHOUT killing you electrical system, or the audio system.


All Cicada Audio 8 inch MidBass and Coax Horns need to be “CUSTOM“fitted.  They do NOT drop in for an easy install (but neither does 95% of all 8 inch out there!!). These ALL NEED TO BE CUSTOM fitted.  We recommend you find a good motorcycle audio guy to do your install.
