Overview

Our take on the Polk EX357

Polk designed the EX3 Series to deliver audiophile performance, whether they're powered by an in-dash receiver (even a "factory" model) or by an external amp. The EX357 5"x7"/6"x8" speaker pumps out impressive bass from a moisture-resistant mica-filled polymer composite woofer with a durable butyl rubber surround.

The EX357 5"x7"/6"x8" speaker pumps out impressive bass from a moisture-resistant mica-filled polymer composite woofer with a durable butyl rubber surround.

A 3/4" soft dome tweeter broadcasts smooth, detailed highs, while the REL (Rotating Elliptical Lens) improves imaging, even from less-than-ideal factory speaker locations. Grilles are not included. (Factory grilles are appropriate for most installations.) 1-year warranty.

polk 5X7

Jason and Leisha from San Angelo, Texas on 10/17/2005

Crutchfield Customer Review (What's this?)

Well, bought the polks because of the reviews(of course). One set for my pick up, back doors, and two sets for my Expedition, both doors. I placed them in the pick up first and was a bit disappointed. While they sound good for mids and highs(what they are designed for), they are no good for any tid bit of lows which some of the reviews led me to believe. So I decided not to put them in my expedtion. I am still deciding which ones to put in there. While these are decent speakers, just ensure that you know what you are buying them for and what you want them to do for you. They did distort a bit at the middle to top end of my volume control.<BR><BR>All in all do your research and read ALL of the reviews.<BR>

Great speakers for use with a subwoofer

Adam from WI on 10/10/2005

Crutchfield Customer Review (What's this?)

In the past I've used JBL Decade (good bass, rather muddy), Infinity Reference (nice, but a bit shrill), and a few others I can't remember offhand.<BR><BR>These Polks sound far better than anything I've heard in the $80-100 range. The mids and highs are very natural and clear. The tweeters are especially nice--they do not have the harsh, tinny sound common on less expensive speakers.<BR><BR>The reason I didn't give them 5 stars is that they do not have much bass response at all. In fact, they put out significantly less than my stock speakers. <BR><BR>For this reason I wouldn't recommend that they be used alone. However they work wonderfully in conjunction with a subwoofer, and you'd have to spend much more to beat their overall sound quality.

Just what I needed

Kevin from Sringfield, Il on 8/31/2005

Crutchfield Customer Review (What's this?)

I bought a pair of these for my Ranger regular cab. There isn't a lot of room in the cab, but these speakers more than fill it with great sound. I went from stock factory speakers to these, and I love 'em. Great highs, great lows. And the installation instructions were dead on. Took me 30 minutes to get the pair in.

Cons:

Great speakers for the price

michael from Houston,TX on 8/25/2005

I purchased two sets of these for my 2004 Ford Escape. Without a doubt a great deal. Only running them of the power of my Sony CDX-F7700 and injunction with a MTX 6304 4 channel amp running two MTX 8000 12 subs, these speakers sound incredable compared to stock speakers they replaced. For a vast improvment in sound at a cheap price, these speakers can't be beat.

clean and crisp

William from Cartersville, Ga on 8/24/2005

2005 Ford Explorer
Crutchfield Customer Review (What's this?)

I installed 4 of these in my 05 Explorer. They are the cleanest speakers that I have heard. I use them for mids and mid bass. They do need a lot of power.I am driving these with an Alpine MRV F340 @ 2ohms and 65 watts times 4. My head unit is an Alpine 9833. I'm using an Alpine MRD 301 Sub amp with an Alpine 10" Type R DVC Sub in a sealed enclosure. I'm using a pair of 1" Infinity silk dome tweeters. I can push my HU all the way up to 35 and there is no clipping. Only loud and clear music the way it was meant to sound.<BR>Take the time to set your system up right and you will not be disappoinetd with these speakers. Low powered Amps cause clipping and damage speakers.

Won't Stand Alone for the Bass at Heart

Scott from Atlanta, GA on 8/17/2005

Crutchfield Customer Review (What's this?)

These speakers sound absolutely fantastic. They do lack bass response, but with the help of a subwoofer, these are almost perfect. With the current $30 Crutchfield price tag, there's certainly no way to beat the value.<BR><BR>With the help up the Crutchfield supplied wiring harness and installation information, I installed them in about 15 minutes in my '93 Ford F-150.<BR>

Clean and tight

Wylie from Norman, OK on 8/15/2005

1994 Mercury Villager
Crutchfield Customer Review (What's this?)

I bought 4 of these for my Mercury Villager with the upgrade sound system and man, do they sound good. The highs are extremely crisp and clear and midrange is full and accurate - a huge improvement over the factory two-way speakers for a very reasonable price. They seem reasonably efficient, also, with good volume given the limited power I have to drive them with.<BR><BR>The only drawback to these speakers is a relatively weak bottom end, but a sub or two should take care of that. I'm having to repair my 6" factory sub since there are no aftermarket replacements, but if that doesn't do it one more powered sub should easily get me there.<BR><BR>If accuracy in your music is more important to you than huge, thumping bass, (or if you plan on using a sub) these speakers are a great deal.

Very Nice Deal

Eleanore from TN on 8/10/2005

1995 Ford F Series
Crutchfield Customer Review (What's this?)

I installed these speakers in my Ford F150 and the difference is phenomenal! I moved the fader back and forth between my old speakers and new ones and the highs are crisp, the midrange is nicely detailed and the bass is much clearer and less distorted on these. My one gripe is the bass volume isn't there, it is only slightly better than the old ones. You can really mess up the midrange if you ask too much bass of these speakers. Other than that, you can't do any better at this price range!

Not bad, but not great..

Tim from Peck, MI on 7/25/2005

1994 Ford Explorer
Crutchfield Customer Review (What's this?)

I bought these speakers, knowing they wouldnt be awsome, but they'd be better over stock. They are better over stock, but not much. I still can't turn my HU up much louder then 20 Alpine CDA-9847, Ive pushed it to 27 on the HU, it goes to 34 i think, and that was about as far as i wanted to push it, with the bass FLAT, At 0, and it was clipping and didn't look like it could handle the power. Even with the bass blockers, it still wants to clip. My buddys got a all pioneer system, and he cranks it to the max and its clear as a bell. But, For $30 They arn't bad. I'd Prefer some infinity's, but, i'll save up for those. Basically, they are not bad, but there not great. Sound better over stock, but there are much much better speakers out there. Buy them at your own risk, You might like them, you might not, everyone has diffrent tastes when it comes to car audio.

Excellent Deal

Ian from Killeen, Tx on 7/17/2005

1993 Mercury Villager
Crutchfield Customer Review (What's this?)

I just recently purchased 2 sets of these to replace the factory speakers in my wife's Mercury Villager because of the quality I know to come from Polk Audio and the price just couldn't be beat. I am so happy with these that I am including them in a quote I am doing for a friends Ford F-150. I do plan on purchasing an amp as my Kenwood deck just doesn't have the power to feed these properly though. I HIGHLY recommend these to anyone looking for an excellent deal on some 5x7's!!!

Bryan from Albuquerque, NM on 6/21/2005

1997 Ford F-150
Crutchfield Customer Review (What's this?)

For less than $30.00, what can I say, WOW! These guys dropped right into the stock location of my '97 Ford F-150 (thanks to the great mastersheet instructions provided by Cruthfield) and immediately, I was hearing parts of my music that just were not in my vehicle before. Crisp highs, clean midbass, far exceeded my expectations. I consider myself an audiophile and have owend MB Quart and JL Audio in the past (before I had a wife, daughter, mortgage, needed to eat, etc...) and while I will not say these sound as good, I will say that for the price, they will stand up to and surpass many of the higher priced speakers in their group. And with the scratch I saved on these, I will now be able to upgrade the head unit much quicker than anticipated. Thank you Crutchfield for and awesome product at an unbeatable price!!!

great thump for the price

JP from New Jersey on 6/16/2005

1992 Ford Tempo

I just installed these on the rear deck of my 1992 Ford Tempo(ugh). For 30 bucks, I knew they wouldn't be the best, but after testing them and playing them to Black Rob's "like whoa", I thought that i had a few 10's in the trunk. These things are great for the price and won't shake the neighborhood, but maybe a neighbor or two.

Clean Sound

James from Cleveland, Ohio on 6/4/2005

I was worried that for a cheap price I was going to get cheap gear, but I had come to trust Crutchfield from friends who have shopped here before. I decided to go with the Polks and I can tell you that I am not dissapointed at all. I love the clean sound I get from the speakers. I do wish the could go a little lower, but I know Polk is known for clean and clear sound. I love my speakers. I reccommend these speakers to anyone who needs new speakers. I will come back to Crutchfield when I am ready to install a Sub.

1998 Ford F-150
Crutchfield Customer Review (What's this?)

I have been a long time lurker at Crutchfield.<BR>I will be back for the savings of do it yourself, and good customer service.<BR><BR>I bought a set of these speakers for a 1998 Ford F150. I hooked them to the factory amp/head-unit and figured they would be good considering the 2-60 watt RMS rating. I didn't want a speaker that needed tons of power since I don't think the factory unit has much to spare.<BR><BR>I was really impressed at the difference just two front speakers made! After seeing how easy the back speakers are to install (thanks to the Crutchfield Master Install Sheets), I plan to get another set right away. These are perfect for replacing junk factory speakers.<BR><BR>Installing myself was easy, and MUCH cheaper than any local store could offer. At this sale price, these are an amazing value.<BR><BR>Thanks Crutchfield ~Jim (Canton OH)

Walter from Baton Rouge, LA on 4/28/2005

Crutchfield Customer Review (What's this?)

First of all Crutchfield is one of the best online companies out there. I bought a pair of these polks to go into a 89 mazda 626. totally redid the rear deck. I also have a pair of infinity reference 6.5 comp in the front doors. which are in a set of pods. the 5x7 were for rear fill considering I am running 2 12 inch pioneer premiers. those polks play every note that is throwing at them. and can handle some good power. I am running a Phoenix Gold R5.0:4 which is 50x4 rms. this is ran at about 80 hertz high pass. And it sounds great. the pioneer premiers are running off of a hifonics brutus 1500 at 2 ohms with a 1 farad cap. the head unit is a Panasonic cq-c5210. which is a 5*. so in closing thanks crutchfield. And thanks to MST car audio installers in prairieville, LA. <BR> <BR><BR><BR><BR><BR><BR><BR><BR><BR><BR>

Mike from Rock Hill, SC on 4/17/2005

Crutchfield Customer Review (What's this?)

I purchased 2 sets of these and a JVC KS-FX490 cassette receiver/CD changer controller. The sound is incredible! The REL really gives you a lot of control over where the "highs" are in the vehicle...even when the speakers are located low in the door.<BR><BR>I should have upgraded the factory system a LONG time ago! Thanks to Crutchfield for JVC-Polk special...what a deal!

IKE from San Antonio, TX on 3/10/2005

Crutchfield Customer Review (What's this?)

I purchsed 2 sets of these speakers for the front & rear doors in my 2001 Ford Expedition and they are great. They are powered by a 200-Watt Kenwood cd deck. I have to turn the volume way too high before I even get any kind of distortion. A super buy!

Features

Woofers: The moisture-resistant mica-filled polymer composite woofer cones produce full, accurate midbass, while the durable butyl rubber surrounds increase speaker life and improve bass response.

Tweeters: Each speaker uses a 3/4" silk dome tweeter for smooth, accurate highs.

Rotating Elliptical Lens: Each tweeter employs a Rotating Elliptical Lens that allows you to redirect and focus the high frequencies for pinpoint imaging and clear detail, even from off-axis factory speaker locations.

Anti-Diffraction Tweeter Post: The Anti-Diffraction Tweeter Posts are shaped like a funnel to minimize driver "bounce back", resulting in less distortion.

Mounting Rings: The supplied plastic mounting rings allow the speakers to be installed in 5"x7" or 6"x8" openings.
