Alpine Authorized Online Dealer

Highlight the highs

Alpine is known for quality sound and that reputation carries straight into their SPS-110TW tweeters. If your vehicle's speaker system sounds dull and unfocused, you'll be impressed by the excitement and detail these Type-S 1" tweeters will add to your music. And, if you like to turn it up loud, these silk domes will handle up to 100 watts RMS so they'll fit right into a high-performance system.

It's all in the details

These tweeters deliver rich high-frequency performance without ever turning shrill. An EQ ring in front of each tweeter helps to disperse the sound evenly, while the tiny outboard crossover network ensures the tweeter receives only the frequencies it was designed to handle.

More natural sound

Alpine includes hardware for mounting the tweeters in the best spot in your car. Once they're installed, you'll hear all the details in your music, and all the instruments and voices will sound more defined and natural. You can choose from four tweeter levels so the high frequencies are balanced with the rest of your speaker setup.

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: 5-100 watts RMS (300 watts peak power)
  • frequency response: 1,000-22,000 Hz
  • impedance: 4 ohms
  • sensitivity: 88 dB
  • flush-mount depth: 11/16"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Great replacement

Crutchfield Customer Review (What's this?)

These tweeters added a silky smooth layer of music on top of the other outstanding speakers I've installed. In my 2001 Chevy Silverado, I had to get creative on mounting them but they are well worth the headache. (I'm no expert handy man so it may be easier for others)

Pros: great sound, fair price, nice looking

Cons: a little difficult to install

Perfect Addition For Small Sports Car

Written by: beg3yrs from Tucson, Arizona on October 31, 2015

Crutchfield Customer Review (What's this?)

I purchased these tweeters to provide a little audio "pop" to a car I've been restoring. This 1974 beauty was never designed for a decent audio system and really only supports some dual 6x9s in the back hatch area. Putting these in the door cards was a simple job and added just the right amount of fill and high-end this car needed. Great product for the price.

Pros: Small and easy to install. Has more lower end response than other comparable tweeters. Was happy to see cross-over filters were included.


compared against infinity 10.11

Written by: skamin20 from Iowa on October 7, 2015

Crutchfield Customer Review (What's this?)

Compared these against the infinity, I kept the infinity. Both sounded fine I just thought the alpines were a little harsher not much. The alpines were a little bigger and bulkier for where I wanted to mount them. Flush mount would be fine but i didn't do that. Would be fine to have on a lower budget. Not near the attachments as the infinity, cross over was in-line and was told it wasn't as good. Wouldn't be afraid of owning them for the right location

Pros: sounded fine price decent

Cons: weaker crossover bulkier for my application maybe a little harsh compared to more expensive tweeters

One of the best upgrades I have done

Installation into the OE tweeter location was a little tricky but figured a solution out.. other than that these blow away the OE set up clear crisp sound

Pros: Great Alpine Sound

Cons: none

Crutchfield Customer Review (What's this?)

Put these in My 2010 jku. What an improvement. I switched out the passenger side and turn on. It is much clearer and louder than the stock Driver side. They do not fit in the tumbstone. I took a drimmel to it and Popped them int. When I get more time I will get it a little more snug but fine for now. With modding the tumbstone and hooking up took about 10 min each. Wish I would have done this years ago. You can also tilt them some to direct them right at you. Only in for a day but what a difference.

Pros: Easy install. Nothing else needed Except wire nuts. Look and sound great. Comes with a few options for mounting in different places. (did not use any Myself) Crutchfield customer support is the best.

Cons: Did not fit my factory tumbstone. (not a real shocker here. The advisor told me I would have to fab something.) Just because I had to have at least one con.

Alpine Tweeters

Written by: Anonymous from Georgia on June 3, 2014

Crutchfield Customer Review (What's this?)

This is my second set of Alpine SPS-110TW tweeters for my truck. The first set met an untimely end on my part for not adjusting my settings properly at first. Learned my lesson and with this set and they installed easily without needing to replace the whole housing (push in and twist the back of the tweeter housing to open it and pull the old tweeter out). The sound from them are crisp when adjusted properly and fill the cab of my truck with notes not normally heard making the experience that much more enjoyable.

Pros: Crisp sound, easy installation

Crutchfield Customer Review (What's this?)

I replaced the factory front tweeters in my '12 F250 and it really helped brighten the sound. I dont hear well above 800 hz so I needed that.

Pros: small enough to fabricate holders for

Cons: no direct bolt in. must fabricate way to hold them into the tweeter tower

Crisp and Clear

Written by: Tom L from Avon, CO on October 23, 2013

Crutchfield Customer Review (What's this?)

Since everything on my 4Runner stereo upgrade was a retro-fit, these tweeters were on par with the other components as far as install. I put them in the dash where the factory speakers had been, and modified the previous speaker structures to hold the new tweeters by tearing out the old paper cones and cutting the metal frames where the struts joined the magnets. The result was a perfect fit of the new tweeters, and a great high-end sound after the project was finished.

Pros: Great sound, reasonable install, very good price, adjustable sound direction.

Cons: None so far.

These Things Scream!

Written by: Zack from Billerica, Massachusetts on October 1, 2013

Crutchfield Customer Review (What's this?)

WOW! These tweeters do work! I have them running off of the 25 watts per channel that my head unit has to offer and already they are really loud! I will be amplifying them with 50 watts per channel soon. Other than loudness, these look great. They have crystal clear quality, and are adjustable. You have no idea how much quality and fullness you are missing until you add a set of tweeters to your system. Well worth the price!

Pros: loud, clear, crisp, fills the car with great high end tones, can be used with little power, but will blow your mind with lots of it, look sexy, adjustable, flush or stealth mount, built in crossovers, competitive price

Cons: large crossover might be hard to route through certain areas, does not come with surface mount hardware, i cannot seem to find the limit as to how loud these tweeters will play.

You won!t regrest the buy

Factory upgrade

Written by: Rod from San Bernardino, CA on June 10, 2013

Crutchfield Customer Review (What's this?)

I've been putting off upgrading my factory stereo system for quite some time and I finally came around to it, with these Alpine SPS-110TW, I already had purchased a pair of 6.5 Alpines. The first pair had a defect and I called the support line and they sent a replacement immediately. I love it... My next project is to upgrade the stereo and add an Amp to bring out the deep sounds. Doing it myself is great because it's self-satisfaction of doing it perfect with your Tech-line for assistance.

Pros: Able to take my time and do it right. It's simple, if you are willing to make modifications to your door panels.

Cons: None

great tweeters

Written by: DannyT from Massachusetts on June 6, 2013

Crutchfield Customer Review (What's this?)

I drive a '95 Volvo 850, and the tweeters that came standard in my dash stopped producing any noise at all. Naturally I wanted to replace them. I chose these because they were a good price and I was told they were easy to install. All I had to do was take the old tweeters out of the bracket and screw the new ones in using what they came with. There is tons of extra speaker wire so they're easy to install if you need to run all the wires too. They added the high notes my system was missing, and really brought everything together.

Pros: simplicity of installation, price, quality

on my scond set it 3 months, thought i did something wrong on instalation, no just poorly designed, tabes brake off at speaker.

Pros: easy to mount and great sound when they worked

Cons: extremly poor design

Sound good, design poor

Written by: robbie d's specialties from Tallahassee, FL on November 22, 2012

Crutchfield Customer Review (What's this?)

The tweeters sound good. I have them powered by a JVC KD-AHD69 Head unit. Cutting holes in my Honda Accord door panels was easy. The bad: the back of the tweeter was held on by three rotating clips which broke off of one the tweeters. I could have mounted the speaker differently after the breakage, but I had already installed the other side. With the back broken, the rotating feature was to be eliminated. I had to by Epoxy to seal the back to the super strong spring on the back of the tweeter and hope that noone plays with the speaker. Other than that, they are up to Alpine's sound quality standards.

Pros: Swival feature/rotating angle for sound balancing is a great plus

Cons: poorly designed plastic covers on the back of the tweeter

Very good tweeters

Written by: Doug from Golden, Colorado on November 13, 2012

These tweeters rock! They have great sound at high volume and the included in-line crossover eliminates the possibility of distortion.

Pros: Clear, loud high-frequency sound. Awesome hi-hats and cymbals.

Cons: None

Very nice

Tweeters sound great in my extended cab truck. I am very satisfied with them. I would highly recommend them.
