Better components give you better detail

Each 5-1/4" speaker sports a stiff polypropylene woofer cone that delivers strong drums and bass, along with clean reproduction of the midrange frequencies. Rockford Fosgate mounts the silk dome tweeter flush with the woofer so it'll fit in more vehicles while adding the excitement of strong high-frequency response. The built-in crossover network divides the frequencies going to each driver, so all your music plays faithfully. Grilles are included.

Product Research


Tweeters: Each speaker features a 1/2" Silk dome tweeter. The embedded design maintains the correct phase relationship between the tweeter and woofer, and doesn't add to the speaker's overall height.

Klippel Analysis: By using a state-of-the-art Klippel Distortion Analyzer, Rockford Fosgate engineers can optimize the speaker's motor structure, voice coil alignment, and suspension for the best possible performance and the lowest distortion.

39.99 for the pair, so you full investment to have the four will be 80, but well worth the money. [ Norman  Oct 26, 2018 ]
It comes in pairs meaning if you want 4 speakers total, order a quantity of 2 [ Christopher  Oct 25, 2018 ]
It is 2 speakers per quanity yes. So you'll need to order 2 quanity. It should be around $80+. [ Zachary  Oct 25, 2018 ]
Well it come in set of 2's for left side and right side per box.So, if you're doing all doors then you will need to buy 2 boxes. [ Dewayne  Oct 25, 2018 ]
I don't know the cone diameter, but I do know that Rockford Fosgate does list these speakers as needing a 4.696" cutout for both top and rear mount. Given you have 4.71"I would expect these to work for you. HTH! My Bio: [ Paul  Dec 31, 2017 ]  Staff
Thanks for your question. The cutout diameter is listed as 4.696". Hope this helps. [ Kenny  May 13, 2017 ]  Staff
Thanks for your question. The depth you mentioned is correct from the screw holes down as a top mount. Overall height from top to bottom is 2.079". Hope this helps. [ Kenny  May 08, 2017 ]  Staff
Take this with a grain of salt, I'm just a customer, but they handled last winter in Seattle really well (The wettest on record), where there was mold and mildew (and some level of raindrops) on everything, though they are not specifically marine speakers. If you need something specifically splash-able, think about something marine specific, Polk Audio makes some DB650's that kick.. Not sure what your fitting requirements are.. [ Lucas  Apr 05, 2017 ]
This will depend largely on your vehicle. For details on installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation. [ Kenny  Jan 18, 2016 ]  Staff
If your referring to the mounting bracket it does. As long as you have entered your vehicle into "what fits my car" the correct mounting bracket will be included. Make sure the "it fits" is next to the speaker you've selected. [ CLINT  Jan 15, 2016 ]
I installed my pair with a standard Sony receiver on my harley Davidson Electra Glide. At 50 mph I have to turn the radio up and I still get an awesome sound from these speakers, (Rockford Fosgate Prime R1525X2) I highly recommend them with a stock or aftermarket system [ DONALD  Jan 08, 2014 ]
I don't quite understand your questions, but I'll say the following, as long as you have space for a 5 1/4" speaker, and your radio has enough power, they should sound OK. They do not reproduce much bass, so I use them in my front doors as mid-range speakers, since I have a powered sub-woofer in the rear to handle the heavy bass. Hope this helps out. [ VICTOR  Jan 07, 2014 ]
Pretty good sound from these speakers. Idk if your stock ones are premium but if not these will be better. These won't effect your head unit, they will use whatever amperage its putting out. [ CHAD  Jan 07, 2014 ]
Upgrading your factory speakers is always my first step. Even if you don't have a factory amp ie Bose or any other type of "upgraded" factory system. The sound quality over paper speakers is so much better. However if your factory head unit doesn't have enough RMS power to push these you may not get the full flavor sound your looking for. But I have these with my factory head unit and they sound great. So there are a ton of variables when it comes to car-fi. But it's up to you. But to answer your question Yes they are worth it [ MATTHEW  Jan 06, 2014 ]
My personal experience with these speakers is a great one. They sound so much better than the original ones that were in my truck. The sound is crisp and clear even at high volume. They also sound great accompanied by a pair of subs. I would say they are worth the investment. [ APRIL L  Jan 06, 2014 ]
