Jessica Posted October 13, 2013 Report Share Posted October 13, 2013 So, i am bored and when i get bored i overthink things. So, in direct violation of using the KISS method and throwing out all logic, I am going to post this question here and see what happens. Feel free to call me an idiot if you like, i am just trying to learn here. Also, I'm not so diluted i think i have an SQ setup. But that's no reason to not try to get the most out of what i have. With the power I have i should be able to get a decent amount of output and still have a good sounding setup. Alright, down to buisiness. Try to keep up, my posts tend to become train wrecks of text. I have two sets of t1675's up front, so 4 mids, 4 tweets. I have a couple ideas rolling around like these. Tell me what you think or give me some ideas or tips. 1. Run tweeters a different gain levels to reduce standing waves and odd overlapping harmonics(yuck). I am speaking about something like one set (left and right) at one level, and the other (left and right) lower. 2. Running overlapping crossover points on the tweeters and mids. Think of it like one set of tweets at 4k 12db slope, and another set at 3k 24 or 18db slope. Maybe run the mids lpf at slightly different points and or slopes too. 3. I can do time alignment, at least i think so, the pioneer 80prs claims time alignment but i think it may just actually cut levels on different outputs just to trick your ears into thinking the sound stage is more center. Maybe someone could chime in on this. 4. To that point, if the time alignment is legit, is using a tape measure and setting the distance to each speaker going to be close enough or should I consider other things when putting in the measurements for each driver. Thats about all i got right now. I'm sure i can come up with more questions though. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.

You can trial and error if you like ... but I'm almost positive that you will find that you will have better luck with a single pair of tweeters crossed over around 3000 htz ... actually, mine are crossed (passive) at 2600 htz ... Having a pair of midbass drivers in each door should not be a problem, and should be fairly easy to time align ... given that they are aiming in the exact same direction ...

A processor isnt needed, just a good hu and running active wont hurt. ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...

That head unit is a great stand alone setup ... i know of atleast 3 Team vehicles with this head unit ... Best tools for time alignment ... measuring tape, calculator, and the human ears !!!

ToNasty Posted October 15, 2013 Report Share Posted October 15, 2013 the only reason i say active is because it will make time allignment easier, atleast in my opinion. I wouldnt run multiple comp sets for sq (thats just me, im not saying its wrong), just a set of midbass, midrange , and tweeter. all in differant locations in the vehicle. ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
