The Greatest 6x9's
2003 Mazda Protege
They are quite simply the best coaxial speakers I have ever heard, period. I have been involved with car audio for 30 years, having competed and judged IASCA shows through the 90's, and later working for Phoenix Gold in mktg./pr. These are truly in a class by themselves. They truly are as good as even the best separates (I am using both the 6x9's in the rear and the 6.5" of the same series in front), I had at first bought a set of ALpine Type S speakers but they sounded incredibly shrill and underpowered compared to the Pioneers. They image better than the Boston Pro series 6.5" and the MB Quart Refference Premium separates. This is partly due to the amazing tweeters employed. They are larger than the 1" tweeters typically included in better component sets, and b/c of this they play lower than most tweeters, allowing a lower x-over. As a result there is no "hole" where the tweeter meets the midbass (a problem with most large cone coaxials). These speakers posses both high-pass and low-pass filters with steep slopes which is also why they image so well. With speakers as different as a 6x9 cone and a 1.3" ceramic tweeter, it is Critical that they overlap as little as possible to avoid phasing errors, impedance errors that cause abnormal constructive and destructive interference. Anyway, if you are looking for a "competition-level" set of coaxials without spending a fortune, You Must Hear These!!
Pros: Amazing imaging, besting componet sets costing Many Times More (using Sheffield Labs IASCA evaluation CD), a Serious Slice of low bass (like a good 8" subwoofer), can handle over 100 watts RMS without breaking a sweat (I am currently feeding them that much but they can take Much More)
Cons: Absolutely None. OK, they don't look very flashy (but it's the ugly ones that sound amazing; crappy ones hide their shortcommings with bright colored cones, oversized but unessary baskets, and other useless gimicks
