Overall, a really nice set of components for the price. Quality seems great. Mid to highs are very clear and precise, but as other reviewers mentioned, the highs (S's especially) can be a little harsh at times, even with the -6db mute button pressed on the crossover. The tweeter body's and mounting cups are rather large, which may or may not limit your mounting locations. It forced me to put mine in the door panel, which could explain some of the harshness due to poor angle. They are listed as 2 ohm impedance, but like one reviewer mentioned mine are ~3.2ohms at the speaker, and a little more when measured through the speaker wire. The crossovers are really nice... count on losing that tiny hex key though. These things shine with a little juice... it would be a great injustice to power these by the headunit or a poor quality cheap amp.

At first I installed the tweeters in some custom A pillar pods and the mids in the doors in my 94 silverado ext cab. I found the tweeters to be overpowering in relation to the mids even with the -6db switch activated on the x-over. I remounted them in some plates to fit in the factory dash location and have them firing towards the rear view mirror and the -6db switch still on. Huge difference! very well balanced and surprisingly the imaging was still quite good. They fit the Infinity reputation of good, accurate sound reproduction. They are only running on the deck power of an Alpine 9886 right now, but they are very clear and full sounding at a moderate volume level. I can't wait to amp them.

The tweeter mounting hardware is VERY big for only having a 1" dome. Mounting locations are very limited. They do have the capability of pivoting a large degree in their pods, so that helps. The grills for the mids look very nice and upscale, but do not blend in with the interior very well. They kind of look aftermarket. The tweeters look stupid to me. They are now hidden under the factory speaker grills, so now it doesn't matter.

Don't let the "Engineered in the USA" label throw you off. They may be "engineered" in the US, but they are unfortunately made in China like most everything else (like my Alpine deck). However, the quality seems to be well controlled. They look well built and so far have lived up to it.

Have had these in the front doors of my Chevy crew cab for about 6 months. They sound FANTASTIC! Very accurate & natural sound. Loud enough to scare my wife even though powered by OEM head unit (the 2 ohm impedance really helps here). The tweets are smooth & sparkling to my ears-very good (I set my crosovers flat on the tweeter EQ). Lots of supplied adapters for many mounting options. HOWEVER-I did not give these 5 stars because the wire terminals on the tweeters have allen set screws that are smaller than the screws in a pair of eyeglasses (1.0 or so mm, don't remember). They are so tiny that it is impossible to get any meaningful torque on them before the (supplied) allen wrench rounds the flats (partially because of the crappy metal EVERYTHING from China is made from). I have had to disassemble my door panels several times to retighten them-a MAJOR pain. I wound up buying a new wrench, putting some valve grinding compound on the wrench for grip, and using some blue loctite on the screw threads. They cannot be soldered because of the design. I have been a professional aircraft mechanic for 25 years, so all of this wasn't that big of a deal for me, but an inexperienced installer might have a problem getting a good connection. They sound so good that at this price it's worth the hassle, but it would have been SO easy to make them with some proper terminals. All of this being said I am buying another set for my son's car. SONIC ELECTRONIX SERVICE ROCKS!!!!!

I have two of these sets in my eagle talon (along with 1 alpine spr-17ref set) and the midbass speakers can produce good sound quality at high levels. I have them crossed over really low n they can handle the sound range. The tweeters can be harsh if not tuned correctly. Overall a good component set for the price. Plus ther american speakers.
