Alpine Authorized Online Dealer

Alpine's Type-S speakers combine outstanding materials and construction with an attractive price. Their efficient design provides powerful sound even when system power is low — yet beefy internal parts ensure they can handle it when you crank the volume.

But powerful output doesn't count for much if you don't like what you're hearing. The SPS-10C2 4" speakers are bound to please your ears — silk dome tweeters render clear highs without a hint of harshness. The aluminum-coated woofer cones move freely in the air-injected rubber surrounds for full, strong, and accurate bass response. Grilles are not included — factory grilles are suitable for most installations.

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.

Silk Dome Tweeters: Each speaker uses a 3/4" silk dome tweeter for smooth high frequencies.

Crutchfield Customer Review (What's this?)

The best speakers for the size. I put the in the front door of my '92 Volvo 240. They sound Great. So much better than the paper factory speakers. Has great bass. Has very nice high sounds. They also have a nice color, they have a stock grayish color. Very easy to install, and look and sound great.

Crutchfield Customer Review (What's this?)

The Alpine SPS-10C2 4" speakers fit nicely into the rear sides of my 92 MR2. No problem wiring them in with the Crutchfield provided wire harness. They replaced a set that had no bass. I was thinking of a sub woofer but no room for it and an amp. The Alpines have a good bass to add some depth to the music. With the speakers being only a few inches from your ear you don't need anything big or powerfull. I am very pleased with the speakers and Crutchfield's service. The speakers arrived two days before they were schedualed to.

Crutchfield Customer Review (What's this?)

It was time for an upgrade on my Volvo 850's factory installed speakers. Since Volvo uses a very unique size speaker in their cars, it was recommended that I purchase the 4" speakers for the front doors since 5 1/4 wouldn't fit. (BTW: 5 1/4 speakers DO fit in a '96 Volvo 850)

I tried these 4" speakers for about 2 weeks and was a little disappointed in their performance. I think the main reason for my dissatisfaction is due to the fact that they are only 4" speakers trying to replace larger speakers that were previously installed in the car. Basically, there was not enough bass and they would just barely start clipping when you turned the volume up high. These poor little speakers were not meant to be the main speakers in my Volvo.

Great news though, I returned them to Crutchfield and I STILL bought the SAME Alpine model speakers but in a 5 1/4 size and love them. So overall, it may not be the speakers fault here but my stereo power and compatibility with these smaller speakers. The 4" speakers were great with normal listening volume but if you heard a song you liked or had the windows rolled down and needed to turn the volume up they definitely started to struggle to maintain their bass. I'm glad I stayed with Alpine and got the larger size. Make sure you get the right speakers for the right job.

Reduce ambient road noise and your vehicle's "rattles," for better sound inside your car.
You may need speaker wire to connect your speakers to your amp or receiver.
Keep your speakers clean and dry. They compress to fit behind your speakers.
The right tools will help keep your installation simple and clean.
If your stereo doesn't cut the deep bass from your full-range speakers, a set of bass blockers can help prevent distortion and give you cleaner bass too.
