Low end price on a High end sound
By M. hopkins
I have been into car audio for years. With a new car and some old Alpine V12s and a 10 inch sub kicking around, I decided to 'recycle' parts of an old system into the car. I have never used Polk audio before, but remembered them as having a typically laid back sound. I was pining for Focal Access, but decided to just save the money, since theft is an issue in my area, and cars provide overall lousy audio environments compared to others. My usual listening these days is on a pair of Sennheiser HD 595s (fantastic), so I was surprised when I fired up the Polks to hear that they are overall very balanced sounding and controlled. There were no immediately discernible problem frequencies unlike nearly every other set of car speakers I've ever had. I mounted the midwoofer to an MDF baffle in the factory location, and ended up sawing my A-Pillars for the tweeters to flush mount. This is a fairly ideal set up for the car world, though I typically prefer to keep the mid and tweeter as close together as possible. Because of the baffle however, there just was not quite enough room for the tweeter as well, which would have been partially blocked anyway. I should have noted that these speakers are being fed about 100 watts from an Alpine MRV T707. These speakers would likely make sound from a stock deck, but I personally would not try to run them with less than 50 watts, I'm willing to bet 50 would get you close to loud, 75-100 will get you to 'way too loud.' : ) After several hours of listening, I decided to cut the tweeters to the -3Db position, bumped the EQ up 2 notches at 60 and 200 hz (I like having slightly overemphasized bass), and finally experimented with wiring them out of phase. Mad cancellation when out-of-phase, back to in phase, and all was well. As I have adjusted to them, I have noticed some sibilance in male vocals, though vocals overall tend to sound airy and spot on. Somewhat uneven pitch when hearing piano chords on certain recordings occurs, and very complex recordings can start to sound compressed at higher volumes. Cymbals and other metals sound splashy and crisp, strings sound great, electric guitars crunch and go right through you, acoustic sounds are delicate and clear as a winter night. The midwoofer seems to have no problem delivering bass lines - I have them crossed at a low 40 hz and they don't blink. The sound overall nudges on the bright side, which I happen to prefer, though I would like a little more 'attack' from the midbass. They are probably slightly muffled by the stock speaker grilles - I didn't notice the 'weak' attack when I demoed with the door panels off. They blend almost perfectly with my audiomobile 10, which I crossed at a much higher than normal 120 hz. Overall, these speakers reward placement and experimentation, and their overall quality vastly exceeds the low price tag. I find the Focal Access series (which I also have now demoed) to be brighter, and better overall (much more aggressive but still very accurate and controlled sound) but not nearly warranting the extra 150 bucks. I am very impressed with these speakers, and that says a lot, considering how ridiculously picky I am about audio.Pros:Big, accurate, uncolored, sound, Small Pricecomes with ample speaker wire to use in your doorsflush or surface mounts are literally a 'snap'crossover allows +3, 0, or -3 Db settings so you can get closer to that perfect balanceGood power handling, they don't break a sweat on the daily grindwill likely please listeners that ALSO listen to jazz, classical, rock, and not just todays oversampled R and B, Rap, and Pop genres.Cons:Good power handling also necessitates a fairly beefy amp to run them wellNo included angle mount for the tweeter - I found that irritating. Luckily, off-axis response seems great.Overall build quality of the crossover seems pretty budget minded for sure - we'll see how it lastsNot a fan of putting screws through my door and the crossovers PCB, be extra careful with that, or get some velcroGeneral lack of helpful mounting bits and pieces, comes with lots of 1 inch and longer screws, not a problem for me, but this may create issues for othersInstallation manual is pretty spartan and generally not too helpful for the inexperienced installer (see the Focal site for a better one).

Very nice speakers! Everything came in the box! :) Perfect sound, too. I put these in my 325i convertible. No issues!

By Pi
I put these in my 2003 Corolla CE, powered by the main head unit. (A Kenwood initially, replaced later by a Sony.)Holy carp do these separates improve the sound of my system! The 'rolla CE doesn't come with separate tweeters, but other trim lines do, so I mounted the Polk tweeters where the stock ones would go, on the door just inboard of the side-view mirrors.The added clarity from the tweeters is amazing. It's so much easier to understand what vocalist are singing it's almost hard to believe. These speakers completely blow away the Kenwoods I had originally installed.I'm also running a Polk 12" sub, so I use a high-pass filter to these speakers, so I can't really judge their low-end bass response. But that doesn't matter because these speakers are worth it for the separate tweeters alone.If your system doesn't have separate tweeters, you MUST get a set of these things.
