Perfect
By Thaddeus Hogan
I installed these as a part of the first car audio upgrade I have done since I was in the 10th grade (10 years ago). I wasn't even going to bother with a car audio upgrade unless it could play on the same field as my home stereo. The home stereo is a pair of Polk Monitor 70s, a Denon receiver, and a Martin Logan Dynamo sub. Obviously a tall order.
Powered by an Alpine MRP-F600 amp, these speakers produce excellent, clear sound at any volume. From the inhale of a vocalist to a loud trumpet, at social listening volume to beyond ear-damaging levels, these speakers reproduce the source faithfully.
Installation note: The speaker adapter brackets have a lot of tabs on them to fit a variety of factory mounting points. In some installations you will need to remove the extra tabs so they don't interfere with the door panel. THESE TABS EASILY SNAP OFF BY HAND! I was a dope and didn't realize this at first, so instead of snapping the tabs off I spent 20 minutes making a mess cutting them off with a Dremel. =D

The truth
By Patriotic
I did a ton of research before I bought these. I even went to a local shop to compare them to others using my own sound check playlist. The salesman looked at me funny but he let me do my thing. These were by far the best ones I heard, so I ordered them.
I hooked them up to my alpine cde hd138bt hu. The first thing I noticed was the tweeters seemed to be a little brighter in my truck and there was a sharp peak in the high-mids, around 6 to 8k. Nothing a little eq work couldn't fix. That was fine....for most of the time. Sometimes I like to really crank it though, and the 18w rms from the alpine wasn't enough. So, I wired them to an amp that's feeding them 75w rms each. MAN! What a difference! They're supposed to handle 100 rms. You don't need that much. They sound great with the extra power. Fuller lows(you will still need a sub for any real beef... I recommend a new alpine type-r. You'll be hard-pressed to find components that hit super low because they are specifically designed to be augmented by a sub in most cases. I have a single swr823d and plan on a 2nd one). I even flattened my eq because the highs are way flatter and tamed. I can't really put into words how amazing they sound when setup right. I hear snares and runs on toms with amazing definition. Vocals sit just right. Acoustic and electric guitars, cymbals, horns, acoustic and electric bass, cellos and violins....everything. And this is in my poorly insulated Chevy truck with flowmaster super 40's(I like to hear that v8 too ;-) )
So here it is. If you don't plan on putting these on an amp, don't get them, or at the very least install a 22uF cap across the tweeter posts at the xover to tame the high end. You'd probably be better with the infinity ref 6030cs as they are lower impedance and will be higher output per watt as a result. If you have or plan on an amp, these are it! You should also treat your doors etc(wherever you install them) with dynamat or something similar for the best low end performance.
If you don't trust my 20 years in professional audio(think music festivals for 10000+ fans and live recordings) or my 15 years in car audio, check out the review at bestcovery.com where they were ranked a best pick over alpine sps610c, infinity 6030cs, focal access 165 a1, and Boston acoustics se60. These aren't the "best" but they are the best in class. You can't beat the price either. You can get 2 sets here for less than you'd pay for 1 set at Fry's.
***UPDATE***
So, it's been a few months and the Polks continue to perform exceptionally well. We'll see how they do in the 120+ heat this summer.
I made a correction. Someone pointed out some info I had overlooked previously and they were absolutely right. While (in my opinion) the Alpine SPS610c's do sound good, they are not particularly well suited for use without an amp because of their low efficiency (88dB) as compared to the Polk or Infinity (92dB). (Lower number = more power required for the same level of output) It's been stated that for every 3dB increase in output you need to double the amount of power.
***UPDATE***
So, it's been a year. These speakers have survived their first Phoenix summer, and one of the hottest on record no less. They continue to perform remarkably. My truck was totaled a few weeks ago so these found their way into my CVPI's front doors along with the alpine head unit. Haven't gotten around to installing the amp or sub yet, but these speakers just keep sounding great. I also plan to get a second set for the rears when i get around to finishing the system in this new ride. I would and will buy these again and again

Great speakers!
By M. Moyer
About 3 months ago, I decided that I'd had enough of my factory car speakers in my 2008 Toyota Prius. I haven't replaced speakers in my cars for years so I didn't want to do the whole rewiring/amp/equalizer/etc deal. I simply wanted to replace the stock speakers with better ones. After a couple of weeks of research, I chose these over Boston Acoustics, Pioneer and Infinity because of the sensitivity rating and price.
Before I get on with how great these are, let me explain how bad the old ones were. The stock speakers suffered bad "motorboating"...you know, when a bass heavy piece of music causes the speakers to make a fluttering sound like a motorboat engine. This was a daily occurence, even with the base kicked down two pips. I also had to kick the treble up two pips. Still, the treble was severe. Songs like Alanis Morisette's "Citizen of the Planet" were almost impossible to listen to because the lows were too quiet and the parts where the bass kicked in overpowered the speakers immediately. Once I pulled the stock speakers out, it was evident why they sounded so terrible. The magnets on them were slightly less than an inch in diameter and I couldn't find anything that would actually stick to them.
okay, back to the polk audio's. Installation went pretty easy. I did have to make my own mounting brackets from mdf to fit in the huge holes that Toyota has in it's doors. The tweeters fit nicely in the same place as the stock tweeters were. After the install, I was able to put the treble and bass back to flat. Initially, the bass seemed to be a little week and I was concerned that I would have to put an amp in to correct it. After about a month though, it seemed like the speakers started to loosen up. Now, the sound is great. I know I don't need an amp, at least not with this radio. I'm enjoying hearing new things in my music that I'd not heard before because the previous speakers couldn't reproduce it. One note of caution though....as a regular podcast listener, I happened to be listening to a podcast that, at one point, had a car horn honk. It sounded realistic enough that it caused me to swerve to avoid the imaginary car that was approaching on the right! :)
I wouldn't hesitate to recommend these speakers to anyone!
