Like it loud? Alpine designed their Type-R speakers for people who like to turn it up. They'll deliver big, dynamic sound with plenty of bass, 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.
The Type-R SPR-50C component system features 5-1/4" woofers with multi-layer hybrid fiber cones that deliver really strong bass response. Alpine's adapted the specially ridged surround, originally developed for their subs, to these speakers, so you get consistent, extended cone movement that pushes a lot of air. The silk tweeters produce smooth highs that bring out your music's detail and depth with no shrillness. Alpine mounts an EQ ring in front of the tweeters to help disperse the highs for a larger listening "sweet spot" in your ride. The tweeters mount separately so you can focus the sound better for your seating position.
Alpine uses powerful neodymium magnets which are much smaller than traditional magnets, so the SPR-50C's high-density polymer frames will fit into more places than most 5-1/4" woofers. External 2-way crossover networks control the high and low frequencies for seamless, clear sound — and they're 60% smaller than the old Type-R crossovers so they're easier to install. Type-R speakers have earned their reputation in the past as the masters of "crank it to the max," but Alpine has really kicked the performance factor of the latest models up a notch or two.
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Pros: Awesome speakers
Great Quality and sound at a great price!
I love the sound quality and install wren the very smoothly
Cons: Large compacitor rn th the tweeters
My third time using these speakers. The only component sets I'd ever use or recommend.
In short, these speakers are great! The sound reproduced from these are definitely a huge upgrade from my WK2 stock speakers. It's a little pricy but quality always is. I definitely love these speakers and I also purchased the corresponding type r 6.5 coaxials for the rear. I had these installed for four weeks before I was able to buy an applicable amplifier. I got 100w going to each speaker and the difference is Night and day. With only my kenwood HU powering these there was still much to be desired. It's not the speakers fault though an external amplifier is definitely a must with these. The highs are crisp and clear. I hear details in songs that I didn't hear my previous Polk audio setup with an external amplifier. The mid base is definitely punchy but in part to the external alpine amplifier.
Pros: Large tweeters, quality, clear, punchy, and capable of handling high power.
Cons: Not really a con but you will need a external amplifier.
THESE TWEETS ARE INSANE!!!!! Bought these open box and I have extensively overpowered them with my IA6.4 but they're still kickin butt!!! The IA bass knob has a clipping indicator so I tuned everything to max clean power and never use EQ. Eventually decided to bump the sub channel up to keep up with the speakers at lower volume and this reduced the overall "safe max" clipping volume to a level that my ears can handle better. Had to stop taking so many bass rides because my ears were ringing. Might turn the tweets down on the crossover if I ever get my doors open again because this would probably help balance with the woofers a bit better.
Pros: the most crisp, clear, buttery smooth silk tweeters fill my whole car like a fine mist of perfect sound
Cons: wish the midbass was rated for as much power as the tweeter
excellent sound with infinity k4 amp just like being at jazz concert ,only I get to control the volume!!!
Pros: I get to put tweeter where I want to better balance sound .
Very happy with purchase from Crutchfield. Great product!!
Pros: Crispy sound
Fantastic sound! No distortion at high levels and the tweeters are great!
I paired these with an Alpine head unit along with Alpine R's in the back door along with an Alpine amp and the sound is simply amazing. The clarity and power that these speakers posses are some of the best in car audio today. I highly recommend these speakers! Try them and you will be pleased, Crutchfield as always are the best around.
Pros: Clarity and power with no rattles at higher volumes.
Cons: None that I can see or hear.
great sound quality
sounds very good in 96 ranger. easy install
Sounds great. Awesome upgrade from factory speakers
Pros: Easy install
These are a great pairs of Speakers. I installed them in a 2003 Buick Park Avenue. I rewired all the speakers with new wire and hooked it to Rockford Fosgate Punch P4004 50W x 4 Car Amplifier. I put the Crossovers in the trunk and ran 2 sets of wires to each door. I hooked them up to a Kenwood DNX690HD before the amp it they played perfect.
Pros: They mount perfectly in my car and sound great
Cons: I have no problems with these speakers.
I have been very satisfied with the speakers. They are paid with an alpine amp 110 rms. the sound great and never seem like they are working hard. Very satisfied as I got the second pair half off from Crutchfield special
Pros: Fit in car perfectly. Sounds very clean
Cons: Tweeter is very high... Even with crossover set at the 2nd highest setting. Probably need to adjust it all the way down. Crutchfield service was great!
Maybe it's the Alpine PDX-V9 amp I got to power my system, but something just isn't delivering the punch I had hoped for. While the sound is quality, I was really hoping for a more powerful system.
Pros: Sound quality is quite good
Cons: Not loud enough to satisfy my taste.
Good sound from little speakers. Solid Build.
Pros: Good rich sound. Surprised out quality from such little speakers
Cons: Tweeters did not fit as indicated into car. Had to make some modifications.
These speakers pack quite a punch for being only 5.25". These speakers have crisp sound and a lot of bass. I have it installed in a 2005 Accord EX and it makes my rear-view mirror shake (no sub installed). These speakers are well worth the money as I am only putting ~50 watts rms to each along with the spr69. These speakers are true quality loud speakers as I've owned eminence, selenium, american bass, etc. If you want volume along with clarity without breaking the bank, these speakers are the way to go. If I had the space, I would have purchased the 6.5's as I'm sure they are just as great or even better.
Pros: Very light, crisp, loads of bass.
Cons: makes my doors shake violently even when turned down, dynamat may be the solution.
great looking speakers, highs are nice and clear, missing some of the puch I would have liked
Alpine continues to make excellent products. The sound, clarity, and thump make my '09 Challenger rock out. Love them !!
great speakers. i put them in my dodge ram quad cab. they sound clear and very easy to install. i put them in the rear doors and drilled holes for the tweeters. i have jbl 6x9 in the front doors with an alpine pdx-v9 5 Chanel amp 100 watts rms x4. 500watts rms mono to power the sub. great sound quality and fair price. couldnt recommend these speakers more.
Pros: easy install. great quality and they last had them over a year. recommend a good amp with 100 watt rms. tweeters are adjustable and crossovers work well
Cons: the only cons is that you should use sound damping for vibration.
i replaced the previous gen model with these and i honestly couldnt be more blown away. i do not know how they(alpine) did it but the highs are so much crisper and the mids from the woofer are that much punchier. i highly recommend these components! but be sure to power them properly or you WILL NOT get the full potential these have to offer. i use the pdx-f4, but i think you can get away with using another high quality 4 channel amp. (minimum rms of 75x4).
Perfect fit to my 1991 Porsche! Great sound!!!!!!!!!! Listening to music made a huge sound difference!!!!
Be careful before you puchase one or two of these bad boys...you will hear every detail of the sounds and clarity coming from them. It is so clear and very powerful especially if you add an amp(I reccomend the PDX -F6). With that bein' mentioned...you can wake up the whole neighborhood. Becareful not to blow up your ear drums in the process. This is the best Alpine has to offer!!

Woofers: The Alpine Type-R series component speakers feature multi-layered hybrid fiber woofer cones; for durability and superior linearity, they use rubber surrounds.
HAMR Surround: Type-R speakers use Alpine's multi roll HAMR surround (patent pending), a technology developed for Alpine subwoofers that maintains control and stability at higher volume levels. HAMR surround combines increased cone area and long linear cone excursion for deep, powerful bass response.
Motor Structure: The woofer's High-performance Linear Drive Motor structure features a square-wire voice coil with a large 30mm diameter, driven by a small but powerful neodymium magnet. This design provides linear motion over a wide cone excursion.
Neodymium Magnet: The neodymium magnet on the Type-R series woofers allows smaller speaker dimensions, making them easier to install in a wide variety of vehicles. They are also lighter than designs using standard magnet technology.
HD Polymer Frame: The new Type-R woofers use a revolutionary HD Polymer frame, making the speaker stronger, lighter, and easier to install.
Tweeters: The SPR-50C includes 1" (25mm) silk dome tweeters. Alpine's EQ Ring improves the tweeter's dispersion characteristics, providing excellent off-axis response. When using the flush-mount housing you can also tilt the tweeters up to 15° to focus the sound toward your ears.
Tweeter Mounting Options: The tweeters come installed in a swiveling flush-mount housing. You can also install the tweeters behind factory grilles using the included stealth mount brackets. The stealth mount brackets can be top or bottom mounted. The installed tweeter dimensions are:
|Flush Mount (swivel)||Factory Location (bottom mount)||Factory Location (top mount)|
|Frame Diameter||2.275"||1.7" x 2.8"||1.7" x 2.8"|
Crossovers: The SPR-50C features low-pass crossovers attached to each woofer's input terminal and separate high-pass crossovers in-line between the woofers and tweeters. Because the crossovers are separate, the system can be bi-amped. Two-sided tape is included to mount the high-pass crossovers and their dimensions are:
Tweeter Attenuation: Each crossover has four tweeter level options, allowing you to precisely tune the high frequencies to the car interior and tweeter placement. Using the supplied jumpers select 0dB (no attenuation), -2dB, -4dB, or -6dB.

Needed new speakers and I love bass?? so I got these [ Gino Feb 07, 2019 ]
I like the brand [ leonel Sep 04, 2018 ]
The reviews were all very positive [ Doug Jun 02, 2016 ]
Because the matching Alpine coaxils in my rear doors rock [ Ryan Mar 08, 2016 ]
I wanted to replace the accord factory components with good quality speakers and minimal rewiring. The tweeters in this set mimic the factory setup of an integrated crossover, so easily installed with slight mods to the factory grills. The woofers drop into the doors using the mounting rings? The sound is great! [ walter Feb 08, 2016 ]
Thanks for your question. For information on selecting the best amp I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy Feb 14, 2018 ] Staff
It depends on how you are feeding the wires and the length you have between the tweeters and woofers. On my E36 BMW, I measured the lengths and found that I was nominal for the dash so I had to put them in the doors. The crossovers are small enough to fit easily in either location. [ Derek Oct 20, 2016 ]
I had enough space in my door to Velcro the cross over. But mounting it under the dashboard will work to just need to make the wires longer [ GARLAND L Oct 20, 2016 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Krissy Oct 03, 2015 ] Staff
Vehicle application shouldn't matter for wire size. I generally use 12 gauge wire unless I am running directly from an amp and then I would step up to 10 guage [ Doug Apr 05, 2015 ]
Sorry, i did not do the installation. The tech department at Cruchfield should be able to answer. [ JAMES Apr 05, 2015 ]
18, same as any other type of vehicle [ ZIJIAN Apr 05, 2015 ]
I used 16 gauge speaker wire shouldn't be any different for an 18 wheeler they are going to get the same power to them as in a car [ NICK Apr 05, 2015 ]
