The Pioneer TS-A1072R A-Series 4" 3-Way Coaxial Car Speakers offer a balanced sound reproduction with improved bass response, wide frequency range, and efficient power handling. They are a popular choice for upgrading the audio quality in car audio systems. These speaker features a multi-layer mica matrix cone woofer, which provides rigidity and improved responsiveness to deliver clear and accurate audio reproduction. The cone material is lightweight yet rigid, allowing for better bass response.
It is designed to fit in standard 4-inch speaker openings in most vehicles. It's a coaxial speaker, meaning that it incorporates multiple drivers (woofers, tweeters, and sometimes mid-range drivers) in a single unit.
The "Open & Smooth" sound concept of our industry-leading speakers delivers both sonic excellence and performance. The open-staging and smooth transition of driver response makes for an immersive experience that is truly the ultimate in-car sound.
Open: Open staging and sound characteristics enhance the widening effect that extends way beyond the space between speakers.
Smooth: With smooth transitions between mid-bass and tweeter, sound from these speakers is not marred by crossover frequency dips.


This is a 3-way speaker, which means it consists of three different drivers for different frequency ranges. The setup typically includes a woofer for low frequencies, a mid-range driver for midrange frequencies, and a tweeter for high frequencies. This design allows for a wider frequency response and better overall sound quality.
The A-Series IMPP cone is designed with long aramid fibers to provide strength and durability that powerful bass sound requires. The revolutionary durable, yet lightweight IMPP cones significantly reduce mid-to-low range distortion and reproduce sound staging to a natural effect. The high-density compressed internal architecture is resilient, handles high power well, and transfers sound quickly. The result is a full-bodied, rich sound character with midrange depth that conventional IMPP cones cannot match.

Ok they were a long wait but i did get them just as OCS said " Brand new,factory sealed. great web site and the speakers are really nice looking even though you cant see them but they are nice. i have them power up to the 150watts and they still dont really get bad quauty out of them great highs and ok for mids bass but it is a 4 in speaker so what to you want. they are over all a great deal and a sick speaker to make all the little thing connect. Thanks OCS
nice 3-way speakers. the frequencies are so clear and its highly detailed. its loud and distortion is really not an issue with these speakers
I never thought that these tiny speakers can bring out that much volume for its size. Hooked it up with the head unit and it sounds great. Haven’t tried it with an amp, and I don’t know if I’m going to buy one as I’m already satisfied with the performance of my setup now.
