Alpine Authorized Online Dealer

Alpine's S-Series speakers feature rugged looks and tough, ultra-rigid cones. The 2-way SPS-570A 5"x7"/6"x8 speaker brings home full bass and accurate midrange with its aluminum-coated polypropylene woofer. The durable rubber surround resists deterioration from heat and humidity, adding years to the life of the speaker.

A titanium-coated PEI dome tweeter produces sharp details across a wide dispersion pattern for excellent imaging. You can swivel the titanium-coated PEI balanced dome tweeter up to 15° to fine tune high-frequency focus. Grilles are not included — factory grilles are appropriate for most installations.

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Alpine SPS-570A

Written By Benjammin, Harrisonburg, VA on Monday, March 20, 2006

I put a pair of these Type-S speakers in the front section of my car, which I was greatful to see that such good size speakers could be up in the front.

The bass response could be better, but I'm not too picky because I don't need good bass response in the front down by my feet.

The speakers do not come with a grill, so unless you want your speakers to be at the risk of being kicked out, you have to use the completely restricting stock faceplate of your car.

I'll admit I choose these because I couldn't get a true 6x8 but let me tell you I'm very impressed with the quality of these speakers. They do put out good bass, but remember they are 5x7 so don't expect to thump any with these only. I have a 40x4 Alpine amp pushing these with the 25th aniversary Kenwood HU and they never sounded so good. The positional tweeter is awesome and really does help with imaging. I have a 1990 cougar so it is especially nice since my speakers point horizontally and not at your ears. I push these VERY hard and they have never failed me. I have my amp truned all the way up and even at ear splitting levels they just ask for more. I experimented with some 3-ways a friend purchased and I put these back in because they sounded so much better. I bought these when they where $109 and I think they are a good buy at that price so for the discount they are a steal. If you are in the market for a high quality 5x7 then you need these, nothing else to say.

Crutchfield Customer Review (What's this?)

This is an excellent factory upgrade speaker with good power handling for being driven by the head unit. They are a good fit and great sound. Good bass response and overall frequency range is nice and flat, they don't sound harsh or tinny and bass is not muddy. I'm sure they would sound even better with a clean 40W per channel amp.

Good rear speakers

Written By casual, Oahu, Hawaii on Tuesday, July 26, 2005

These speakers are good for the rear of your car, they have good bass for 5"x7" speakers, and I've been blastin them and they sound great. I recommend these to anyone wanting to get great speakers for a good price.

For the Price

Written By Mlee, Gainesville, GA on Monday, March 07, 2005

These are good speakers for the price and if all your wanting is to replace your factory speakers these are it. They don't require much power so your head unit should handle them fine. If your wanting a system to go bump in the night look at the Alpine Type R. I personally wanted to go with the Type R, but my F150 wouldn't let me unless i wanted to do some cutting. So I went with the next best choice and have no complaints except they aren't Type R quality..

Product Research


Aluminum-coated Polypropylene Woofer Cones: Each speaker features an aluminum-coated polypropylene woofer. Aluminum adds strength and heat resistance to polypropylene, resulting in reduced distortion and improved reliability.

Air-injected Rubber Surrounds: For a smoother response and improved durability, the woofers use air-injected rubber surrounds.

Titanium-coated PEI Balanced-dome Tweeters: Each speaker has a 9/16" titanium-coated PEI balanced-dome tweeter. PEI (Polyetherimide) is a polymer that offers high resistance against harsh environmental extremes, superior rigidity, and sonic purity. When combined with titanium, the result is a tweeter that delivers crisp, clear highs. The tweeters may be swiveled up to 15 degrees for optimum imaging.

Mounting: The speakers can be mounted in a 5"x7" opening, or, using the supplied adapter rings, the speakers can be top-mounted in a 6"x8" opening. The Crutchfield database contains the 5"x7" measurements. When mounted in a 6"x8" opening using the adapter rings, the speakers have the following measurements:

  • Depth as top: 2.239"
  • Mounting height: 0.504"
  • Flange height: 0.376"
