Go pretty loud for coaxials. Clarity.

Lack of bass. The woofers tend to bottom out at higher volumes without a high crossover point. 100hz seems to be the best point for them to be crossed at.

Overall these speakers have great clarity. I used a JBL 180.2 to power these. My head unit is a Pioneer deh-9600mp. They are excellent speakers if you don't plan to have lower mid-bass.

Other pairs in a few different vehicles, Pioneer 6.5's/6x9's...

Included crossover and takes the most power of any speaker I could find.

Not the greatest bass and have to run an amp to them unless you have a beastly head unit.

Good speakers that sound great but definately hook yourself up with a good set of subs to make up for the lack of pounding bass. I got a few bad speakers but Crutchfield was cool with replacing them. Overall best speakers without getting into component systems.

Infinity Reference (for about a week)

Great sounding highs and mids.

Don''t handle bass very well. Cones will rarrle loose in a couple of months with moderate use.

If you are running an extremely loud system don''t put these in your car. They can''t handle any bass. I have used 4 diffrent pairs in my car and all the cones rattle loose in less than three months. I had them running off a Pioneer Premier 930. I even used bass blockers on them to filter out the htz. No matter what they will rattle loose eventually

These speakers are by far the best 5x7 speaker on the market today. They sound great in my van. Currently I'm running them off my high powered deck and they sound great till I really need to crank, then my HP deck cuts them short. The tweeters in these are better than many component tweets and the bass is also crisp and smooth. I run these off my Alpine 7863 and my settings on my head unit are usually +1 for bass and +2 for treble. Enough said. I see theselasting a long while. Wonder if the others hooked theirs up wrong or beat them to death by using a head unit that wasn't suffice.

Does use a lot of power to run these but many other components such as MB Quart at 599.00 has a worst efficiency rating at 86db compared to 89 db.

These are excellent speakers. Unless you want to shell out for components and I mean really good ones, these are the 5x7 deal....Hook these up to a clean amp and enjoy....

I considered the Polks DX7 and am glad I didn't get them. Heard them in my friends car with basically the same head unit as mine and it definitely wasn't as good and they cost about 20.00 a pair more.

Amazing overall sound, especially considering the price paid. The Pioneers I compared with couldn't hold a candle to the Infinity.

At high volumes the highs can be pretty biting and it seems as though the bass kind of fades out.

Basically, my car is a piece of sh*t (perfect condition, just a overall crap car). Looks like I am going to keep it through college so I decided to treat myself to a set of speakers to make riding in the piece a little more enjoyable. The stock speakers were basically a Dixie cup with a small magnet, so pretty much anything is going to sound better. I compared speakers at Best Buy, Stereo King, CarToys and I found that the Infinity speakers sound better - by far. I plopped the speakers in and I was truely amazed what a difference they made. Value of my car is up 15% with these in!!
Go on eBay and buy a pair. They are brand new and I paid $35 less (includes shipping) on eBay than at any of the stores. Trust me, you won't be disappointed.

Great highs, decent mids; nice crisp sound

Takes alot of power to run, they blew after 3 weeks.

They sound great with a nice solid source of power going to them, just don't turn them up too loud. The tweeters stopped working on mine after 3 weeks (that was with quite a bit of abuse). So if you are looking to turn it up, I wouldn't recommend them.

Clear and clean...very loud.

No bass at all. Easily damaged from little to no abuse. I pushed them a little bit with a stock deck and now they have a "loose" vibrate with even the mildest of bass hits them.

I paid good $ expecting a top of the line speaker, but what I got was an over priced piece of crap. I do not reccomend these speakers to anyone, go with Clarion or Cerwin-Vegas. They have decent highs but at the cost of a "tin" sound...lack of bass was infuriating.

Cant hang with any other quality 5x7.

Great highs, mids, and bass.

None!

I have a 1993 Mazda 626 and I originaly wanted to install the Polk DX7 speakers all the way around but found out they were too tall for the rears so I decided to go for the Infinity's in the back and Polk's up front. I must say that enjoy the Infinity's much better. Even though they are only a 2-way speaker they have an INCREDIBLE tweeter and put out a great amount of clean bass. The all around sound is beautiful. I picked these up for only $105 for the pair and it was worth it. I think I'll even get rid of the Polk's up front and put in another pair of these.
I recommend these speakers over any other 5x7 out there!!
