    Help me find some tweeters

    The HAT L1 tweeters don't image well... at all.

    I am looking for something to go with my legatia L3's and L6's.

    Price not really an object, just want something that will image easily and will go well with my other drivers... Clear, vibrant, and not 2 harsh. Links are appreciated.

    Thanks!

    tweeter imaging is not the result of tweeter selection but the result of tweeter aiming/mounting/location.



    have you been helped by me? i'd love to know. shoot me a PM.

    I'll second this. Experiment with different locations and aiming before you decide you don't like the tweeters. I've been experimenting with driver placement for basically the last two years yet I've only changed tweeters 4 times. Two of those configurations had the same tweeters yet with vastly improved imaging. keep_hope_alive is big on install and placement prioritized over EQ, but if you have separate L/R EQ available make sure you use it. You want to make your frequency response curves the same independently left and right if you want 1 seat to sound good. This will really help to improve imaging, but experiment with placement and aiming, and also crossover frequencies and slopes between the mid and tweeter.

    Agreed !

    What I also find, is that alot of people prefer the Legatia L1 Pro R2 Tweeters (ring radiator).

    Re: Help me find some tweeters

    imaging above 3.5kHz is based on intensity. turn the nearest tweeters down a few notches and that should instantly help with the center.

    also, take note of crossover slopes - if you have different slopes for tweeters and mids they can be out of phase at the crossover point (12dB/oct and 18dB/oct have 180deg phase shifts).

    try putting some acoustic foam on the glass surfaces around the tweeters to see if you have reflection issues.

    Re: Help me find some tweeters

    According to Hybrid Audio PDF manuals, between 1 and 2KHz imaging is dependent on both the intensity (level) and distances. Above 2KHz, intensity is the most important factor for imaging. Getting the time alignment set up for the front stage is easy IMO. I personally suspect that getting the intensity right above 2KHz can be more difficult in a car. First, it's not just the tweeter that's playing audibly in that range. You probably need a good equalizer, experience, or a self tuning processor. As a start one easy trick to try is to turn down the level of the closest tweeter by about 1 to 2dB. This can result in in-audible change in frequency response, but imaging can be more consistent. I used to do this before I got Pioneer DEH-80PRS with HAT Imagine speakers. Once I got the DEH-80PRS, I let it do its auto tune thing, and while the low end needed additional tuning, I felt like the resulting midrange and high frequencies imaged pretty well, tonality was also good. The sound is neutral or perhaps a little up front, which I like more. Could the L1 tweeter be worse than the Imagine tweeter in this respect?

    Also I suspect that with hybrid audio tweeter you need to do some work on equalization in the 2-5KHz region. A typical 6.5 woofer installed 30 degrees off axis or more will not give you good dispersion of sound above 2KHz, but a HAT tweeter like L1 probably does not like playing below 5KHz. If you leave it as is, this may result in a too "laid back" sound. Some people like it. I don't.
