We offer 5.25" speakers in both coaxial and component setups. Coaxial speakers are the standard style where the tweeter and the woofer cone are on the same axis and the tweeter sits inside the woofer cone area of the speaker. Component speakers have separate tweeters that are mounted either next to the cone or can be mounted up higher on the door or dash board and most come with an external cross over to send the right signal to the right speaker. 5.25" speakers pretty common and most speaker lines from the top brands include a 5.25" offering. You will find that 5.25" speakers are often mounted in the door panels of most vehicles. We carry a wide range of brands and power handling, as well as both soft-dome and hard-dome tweeters to ensure you get the sound you desire.
