Well i finally have a chance to share with you guys my thoughts on the tweeters that i got to review. i also threw in the Rainbow cal25s that i use in my car now. also i will note that i did get a little picture happy so i will leave most of them out and here is a link to my photobucket so you can look through them if you choose. http://s68.photobucket.com/albums/i2/earhjaco/

I will start by saying that i am not experienced with reviewing high end equipment so everything i say should be taken with a grain of salt. i did try to be as unbiased as possible and i think i did a fair job of it. also i will say that when i do my subjective review my main concern is "real" sounding. i want my stereo to sound like the performer is sitting on the dash, so my review followed that trend

Next i will walk you through the process i used during the tests. each tweeter was placed in a 12"x12" baffle and placed in a vice inside a shop. this was done to avoid any reflections that may be present in my car, and also give the tweeters the benefit of proper baffling. I did not take the time to flush mount the flanges of the tweeter, that would have made it impossible to get through the test in one day which i needed to do since i go to college and work 30 hours a week free time is at a premium.

The first thing i did with the tweeters once they were properly baffled was to determine an optimum crossover frequency. the crossover was controlled by a ppi DCX-730 with LR4 slopes. I started at 3500hz with all of the tweeters and went up or down depending on how they performed at that frequency.

Next was the listening test. One thing that i made a point of reviewing was an output comparison between them. my reasoning for this was because i have not seen that as a part of any other review and i truly believe it can be a big part of choosing a speaker for some people.

Next i moved around in the listening area to get a feel for off axis response. i will give an estimate in degrees of how far off axis these can be used. but remember that this is my experience and nothing else. also i will note that some of the tweeter went from great to terrible in like 5 degrees of movement and others were best in the middle and slowly got worse the farther out you go, those i was forced to give my preference on how far off i would use it.

the last step of the listening test was the subjective review. my listening material was from the ECA sq disks and from Eagles greatest hits for Hotel California.
