they're ok I suppose, for the price. There are much, much better speakers out there try CDT. by far a better speaker, and not too badly priced for their lower models. www.thezeb.com has a great sale on them
Give Infinity Kappa a listen. Best speakers I've ever owned.
pioneers are crap. their sound presents nothing special to the car audio world. and kenwoods suck too. i had some in my car and after about 3 months, the sound quality when down the s hitter, and i never played them to the extremes either. i have jl audio now. ive had the VR525 component set for a year now and they still sound just as sweet as they did when i first bought them. jls are your best bet for price, sq and releiabilityn
i agree with GlassWolfe, pioneers are generally good speakers, especially for the different price ranges they cover.. they are good deals from simple $50 stock replacements to $700 REFERENCE components..
