Alpine SPR-57C

Alpine Type R

I put a pair of these speakers in my work van and the difference is incredible. I have gone from the stock 4 speaker setup to just 1 pair of the alpine's and it is now louder cleaner and more bass. Now i want another pair to see how loud and how much bass i can get.

good price meets great quality

Alpine SPR-57C

I purchased 4 of these speakers, I installed them in my 1998 Lincoln Mark VIII. These Alpines have excellent clear sound and bass response. I have them running off of a Sundown 100.4 amp and they can handle the power easily without distortion. I listen to a lot of different music from A/C D/C, Tool, Mushroomhead, Slipknot ETC. The pricing was also very good and I received them in a short time from ordering. I would recommend them to a friend.

Love Alpine !

i just bought 4 of these speakers and put them in a 2002 ford focus and man do they thump great clear crisp sound too! Remember to hook an amp up to these! Everything about these speakers are amazing! I've done research for awhile now and listened and worked with a lot of different speakers and these are by far the best I've listened to and worked with. If your debating on speakers and cannot decide, choose these! For the price of Sonic Electronix you cannot go wrong.

The last 6x8 you will ever buy!

I have gone through many sets of 6x8 speakers, all of them major name brands. The Alpine SPR-57C is the Best Sounding & Performing Speaker I have ever had and the Construction and Quality is Awesome.

SonicElectronix is the Best Company I have every had the pleasure to deal with. I Highly Recommend this Speaker and this Company.

Thank You.

Speakers!

Just mm from the power windows when windows are down. Now no room at all for windows with Speaker baffles. So don't get the baffles if you want to use your windows. 98' Ford F150.

Alpine SPR-57C or SPS507

I went in my local electronic store & was looking for some Alpine 5x7 Speaker's. SPS507 looked like the one, But seen the Type R that had a 100 watt RMS rating and just needed to have it. So I talked them down to C$100+Tax So I got two pairs of them. On the sound board there wasn't to much of a difference in sound, Type R's had better highs then the Type S, But it wasn't fare that they were just running straight from the Deck. There Good speakers even if you don't have a Amplifier, But you need one if you want it to be louder of course. Mine will only be as loud as 18 watts RMS, I'm getting Speaker distortion around vol #25 with HPF 80Hz, Defeat on (CDA105) I can still hear them speakers over my 1,000w Sub Amp though.

Great Product

Great sounding speakers, sleek look. Overall a good product. Two thumbs UP.

Alpine The best

I bought two pairs of these speakers because I wanted to use the same size as the factory speakers in the doors of my jeep. I'm pushing them with a Power Acoustik bmf 1,600 watt four channel amp, you can here the clarity of the music at a loud volume not much speakers can do that. so all i have to say is buy them you will not be disappointed. WORD.

these speakers handled the 100wrms from my pdx4.100 amp,they didn't distort and sounded awesome through all ranges. i would highly recommend these speakers and also the type r 6.5" splits, my whole system was alpine, headunit, subs, amps and speakers, i had 100wrms through all 4 speakers and 500wrms per sub (2) it was enough to give ear piercing pitches and heart jolting bass, my roof flexed close to an inch with this setup in my suv.
