Pioneer TS-A878 3-1/2" Dash Mount Coaxial Speaker Pair
Pioneer TS-A878 3-1/2" Dash Mount Coaxial Speaker Pair is rated 4.5 out of 5 by 4.
Rated 4 out of 5 by from compactneeded some auxiliary speakers for a old British 2 seater so fidelity was not an issue (just volume). Each speaker fits inside a waterproof duplex outlet box making a compact speaker that can attach to a roll bar.

Rated 5 out of 5 by from Great Dashboard SpeakersThese drivers make for excellent front dashboardspeakers. They have everything you're lookingfor: high-fidelity sound reproduction [within thesize constraints], solidly built but relativelylightweight, shallow mounting depth, and versatilemounting brackets. They fit right into my 2013Dodge Dart with no mods except for the electricalconnections. The only drawback may be the price.They may not be the best bargain in the PartsExpress 3.5" car speaker line-up, but you getwhat you pay for.

Rated 5 out of 5 by from excellent speakersexcellent speakers for the price. I went through several speakers to find one that would fit the dash of my 99 Plymouth prowler. Sound quality is excellent , but would have liked a brighter tweeter.

Rated 4 out of 5 by from Excellent DecisionI purchased (2) pairs of the Pioneer TS-D6902R 6"x9" Coaxial and one pair of the Pioneer TS-A878 3-1/2" Dash Mount Coaxial for my 2011 Dodge Ram 4 door truck. Along with these 6 speakers I installed a Boss 8" 900 watt sub. Also from PE. Six hours later I finally finished the install. (BTW) The dash was a beast to get in. The 6 x 9's are heavy duty speakers and sound is clear and crisp. The 3 1/2" are tight and gives just the right amount of front mid-range and treble combination with the 6 x 9's. Before I was running the Treble, Mid-range and Base controls close to max with the stock speakers. Now I have reduced them to -2 for Treble, -1 for Mid-range and +1 for Base. The spacial enhancement inside the truck is fa-nominal. Music bounces from front-back and left-right. You get a sense of surround sound without the processor. The Sub is more than I need and being it can produce down to 22Hz you feel as well as here the sound. My Next install in the truck is a Pioneer GM-D9500F 800W 4-Channel Class-FD Amplifier. Look for update in about a month. "Excellent Decision part II"

Pioneer TS-A878 3-1/2" Dash Mount Coaxial Speaker Pair

What is the measurement from mounting screw to screw? Is that the 3 1/2" /Thanks

Asked by: gom1947
The 3-1/2" measurement is the outside diameter of the speaker itself. The mounting tabs are designed to accommodate mounting in a variety of situations. The mounting holes themselves are oblong, approximately 4" center-to-center, or 4-1/4" maximum spacing.
