Review: Great little speakers! - Fits well enough- barely- in my 1990 geo prizm. The old speakers were rotten and driving me nuts! Since I picked up the car dirt cheap I wanted some dirt cheap speakers, but I'm picky about sound, so didn't want the new speakers to suck... Yeah, tough situation... I did some research and found these. I like that they are 4 way. They sound great and they're very responsive. I think I need an amp though... But overall they can't be beat for the price. update- 30 Nov 2012 To flesh out my review and provide background- I bought a Boss 612UA MP3-Compatible Digital Media AM/FM Receiver as a low-powered stereo so I could play MP3s off my iPhone or MP3 player on my commute, and some Pyle PL573BL 5-Inch x 7-Inch and 6-Inch x 8-Inch 300 Watt Three-Way Speakers for rear speakers. The stereo is great. The Pyle speakers get 1 star because one sounds fuzzy and blown (only a month in with that weak stereo!). These little Boss speakers are champs for the price. I wanted to wait a while for them to get broken in and have a wide range of music piped through them so I could give a better review. They handle classical, rock/metal (DragonForce), symphonic metal (Within Temptation), and dance (Cruxshadows) with ease and clarity on the 50 watt x4 stereo. I'm able to pick out details I wasn't catching before. They're not heavy on bass (obviously), but for $20, I don't think you'll find a better little speaker (heck, for multiples of that price). I did not expect the amount of clarity I got, and am blown away by getting it at this price! The fact they are 4 way makes a difference. Don't expect miracles, and you'll be pleasantly surprised. Keep in mind that I'm using a cheap under-powered stereo, so I'm not challenging these or throwing them as much as they could/should take, but at my max volume they're still loud (just not ear-bleeding loud) and clear and great for my commute. If you need great little speakers and aren't looking to spend a lot- these are them.
