Exceptional performance, even at high volume

Alpine Authorized Online Dealer

Like it loud? Alpine designed their Type-R SPR-10TW tweeters for people who like to turn it up. They'll deliver detailed, crisp highs and they'll handle lots of volume. They'll work great with your car stereo, but they really come into their own when you power them with an outboard amp.

Fine-tuned for clarity and balance

These 1" silk tweeters bring out your music's detail and depth without any annoying shrillness. Alpine mounts an EQ ring in front of each tweeter that helps to disperse the highs so you get a larger listening "sweet spot" in your ride. The tiny outboard crossover network mounts easily, sending the correct frequencies to the tweeter. You can choose from four tweeter levels so these Alpine domes blend perfectly with the rest of your speaker system.

Installation note: You'll need a pair of our universal backstraps to install these tweeters in the factory locations.

Product Highlights:

  • 1" silk dome tweeters (pair)
  • flush-, top-, and bottom-mount hardware included
  • external crossovers with 4-way level control
  • power handling: 5-150 watts RMS (450 watts peak power)
  • frequency response: 1,000-29,000 Hz
  • impedance: 4 ohms
  • sensitivity: 88 dB
  • flush-mount depth: 11/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Better Than Expected

Crutchfield Customer Review (What's this?)

These tweeters sound fantastic, I would recommend them to anyone. Though not mentioned in the product description, the speaker itself rotates in the mount so you can aim them to your liking. Also, attaching the logo plates is optional.

Pros: Easy to install, plenty of installation equipment. Optional logo plates Speakers rotate in mounts

Cons: None

Clean, Clear, detailed.

I've only had them installed for 4 weeks now and they aren't even broken in yet, So far I'm impressed by the sound that they will produce, somewhat overpriced! But when your on a budget they will get the job done.when I'm able to afford it I'll buy some better sounding (Quality) tweeters "for now they will do, and yes I'd definitely recommend to anyone looking for an affordable upgrade. That being said I'll update on any sound improvement "Thanks Much, Craig.

Pros: Good sound for the money.

Cons: Could be less priced, other than that I'm satisfied.

Great sound

Wonderful crisp clean sounding upgrade to my 2013 Chrysler 300c. They take lots of power and sound great doing it too 10 - 10 in my book!

Pros: Clean crisp sounding highs that can really take the power!!

Cons: A little pricey...

Time for new Tweet's!

Crutchfield Customer Review (What's this?)

So far, only one tweeter is in... these were replacing the tweeters in a nearly antique set of Canton Pullman RS3 components. Canton no longer does car audio, and finding good drivers is tough.

These are a three way set up, like the JL Audio 653 components. 6" midbass, 4" mid range and 1" tweeters.

The old amp died and blew the right tweeter! It was scratchy and generally not pleasant.

The new tweeter is much much cleaner. Works very well with the Canton passive crossover and sound very nice. I am very thrilled with the clarity and musicality of the new tweeters. In general, I prefer the more natural sound of a silk dome over metal tweeters. Silk just has more natural transitions and sounds less harsh.

Pros: Easy to install, great sound.

Cons: Nothing that I can tell.

Awesome enhancement!
