The Image Dynamics CTX65CS 2 way component system is an excellent budget choice for 6.5" components. They come with a massive magnet which you may want to confirm your mounting depth prior to ordering as it could be too big. Tweeters are 1" and included in the box is a way to mount them in a pod or door, or a casing for "free standing" them. The crossover allows for a free different dB settings on the tweeter (will update soon with exact dB). Also the speakers are rated at 100w rms, I personally have mine at 125w rms daily and they take it like a champ.
Sound Quality: 7/10
Power Handling: 10/10
Build Quality: 8/10
SQ: For their price range these probably top out what you can expect sound quality wise but on the grand scheme of things 7/10 is more then fair.
Power Handling: I gave it a 10 as they are rated at 100w rms and I currently have mine at 125w rms
Midbass: The midbass is great but towards the lower end you can tell it doesn't cover that as great, which is to be expected as it will naturally have a rolloff
Midrange: The lower end of the range is a noticible drop off in the "handling" of the frequency.
Highs: The tweeters scream and without being overally "bright"
Detail: The CTX65CS does an excellent job at capturing the detail of the music. Partially I attribute this to the simplistic crossover which shouldn't steal power
Build Quality: Excellent quality, I wish ID did a better job at protecting the surround from the screws as you screw the speaker in place, its easy to end up pinching it.
For the price you cant beat it.
