seems like the RSD's like being crossed low!!

Depends on the install and quality of the drivers used. If the drivers are of fairly good quality and exhibit minimal coloration and distortion, imaging and detail can improve with steeper slopes. In a car the differential mounting locations of the woofer and tweeter can sometimes be a problem but with a good install it can work.

steep slopes can work well, especially when the drivers are close together. my T/A measurements say my tweeters are only about 3-4 inches from the mids. so in my case steep slopes work fine.

Fair enough, its all preference. Some prefer it, others swear by 1st/2nd order slopes. Just with my experience I rarely went over 18db octave...48db is just nuts IMO, you trying to make it a brick wall? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

in certain cases a "brick wall" might work fine. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

it's all about playing around till you find what sounds best. thats all.

Yeah it is definitely a personal preference. In some speakers 1st order slopes can sound amazing and the crossover is seamless.

yup.... also depends if the speaker naturally rolls off on it's own as well. i know my subwoofer still plays vocals and lower mid-range if i use a 12db slope on it.

This is why I see a lot of value in RTA work...you can find the natural roll off of a driver in cabin and use shallow crossovers simply to ADD to the roll off....some of the best cars I have heard used this method...

of course!

there are some that do it that way and some that just tune by ear.

if you are going to compete for SQ i think you'd have to do a lot of each.

That is how any type of "reference" audio sytem, home, car, or professional, should be designed. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
