Note: I installed a Kenwood KMM-BT322U head unit and ran new wires from that hu to the speakers. Initially, I tried hooking into the stock speakers... they sounded thin and muffled. If they were hitting 150hz-10khz, I'd be surprised.

No doubt, these ESX speakers are a distinct improvement over stock. To my ear, they sound like they are getting down to 80 or 90 hz and up to 20khz. I doubt that's flat... probably down 4-5 db at 80hz. The tweeters are harsh. (I had a pair of Energy speakers on my home theater system that I got rid of due to the harsh tweeters... these ESX were about as painful.) I eq'd the high end down a couple notches... MUCH better. I also had to tone down the 150hz range to prevent NPR from sounding like Charlie Brown's teachers.

Now this is without any play in/break in time. I expect as these loosen up the SQ will improve. They will never have the bottom end that I want, so I'm thinking about getting a small 2ch amp to run a set of woofers in the doors... but that's a project for another day.

If you want/need to replace your stock 120mm speakers without breaking the bank, this ESX kit provides drop in convenience with much improved sound over stock.
