Ranger Front Stage (pic heavy)

[cobra93 47]

I know what a couple of 8's can do in the front, but 2- 12's has got to make your sphincter pucker!!!

I don't know if you'd get me out of your car if I was ever able to hear it.

Do you have any idea where your crossing your wide-banders and the 12's at?

I'm curious, if you have time alignment will a phase switch still matter or just change the amount of time alignment needed? Hmm, I guess I'll have to try it and find out.

I have the crossovers built into the HU so I can change the settings while listening. I have had the xover point as high as 1000hz, and as low as 200hz. The higher I have the crossover point, the lower the sound stage gets, And the 12s start becoming over bearing. The lower I go with the crossover point the more the 12s blend. Below 200hz the 3s get strained. Remember this is my first active so I am testing over and over to learn. I have had the crossover point at 250hz for a few months now, 6db slope on the top of the 12s (shallow slope blended better) and 12db on the bottom of the 3s (any less slope they strain). Little by little I get closer to perfection, so I am sure things will change.

As far as crossing the low end of the midbass, the lower the better. I keep hesitating to overlap the sub, but after testing realized the midbasses sounded best crossed LoooooooW. I brought the sub back in and it blends better than ever. I have the 12s playing down to 20hz and the sub set at 30-50hz. The other big reason why I have the 12s crossed so low on the bottom is for cooling. The drivers are designed as subs and need excursion for cooling, as I learned this the hard way.

To anwser your question about T/A and phasing. Even once you have achieved perfect timing of the different sources waves with the t/a, the waves can still be 180 of each other. One sources wave can be in a compression cycle, while the other sources wave is in a rarefraction cycle, the waves will be 180 apart and attemp to cancel each other out. The next thing to understand is wavelenghts change with frequency, so back to how this applys to the mids and fullrangers. The only frequency that applys to phasing between the mids and full rangers is at the xover point because thats where multible sources are playing the same frequency.

I shouldn't say this is the only phasing that applys, because you also want each pair of drivers is phase with each other also. ie: the 3s is phase with each other and the 8s in phase with each other, and then phase between mids and fullrangers. Phasing between each pair of drivers is more across the whole range they are playing, not just the xover point. Usaully notible to me from either severe comb filtering or on driver barking over the other, sounding out of place.

I am sure I will get flamed or corrected if any of the techs read this but its a good general summary of whats going on, with my limited knowledge.

I'm right there with ya.

This is my first active setup and I'm really enjoying the "DIY" drivers.

I lowered the high pass x-over point on the sls's to around 35 or 40 hz. and have not had the sub on for a couple of days.

With the rack in the truck now the sub box isn't working at all, the head unit isn't helping matters either.

I built (2) 1.1 c.f. sealed boxes yesterday and today. I'm going to try them and see if I can make it work.

They're 14" x14" x ~ 18", truncated, so I should be able to aim them pretty much where I want and let them go as low as I want, we'll see what happens.

I'll yank the sub out Wed. and see what changing the phase does for me.

Thanks for getting back to me.

You and the tatman are midbass sluts.

:slayer: :slayer: :slayer: :slayer:

You have no idea, well maybe you do! :woot: :woot:

I just can't figure out how to mount his doors on my truck!!!!

If I do J will will not need keys to get in his car the next morning! where are my doors?

Sorry brother.

Thank you for contacting Eclipse;

Joe,

Unfortunately the owners manual was a miss print the unit goes in to pro mode when you use the PEQ and Time Allignment there was no activation button on this unit.

Tech support.

Well thanks for the reply, but not what I was hoping to hear.

Huh?? Why wouldn't you want to use Pro Mode, that is the whole point with that HU.

Perhaps I am misreading your comment, but I am not sure what you are trying to accomplish if I am reading it right.

Apparently with the 8533, unlike the other eclipse H.U.'s you don't choose a mode.

You have the bal/fad/low/mid and high adjustments like any other radio.

When you go to the T.A. or Para E.Q. you are in Pro mode and both are active at the same time, I can deal with that.

I don't , however , like the fact that it will send full range signal through the front/ rear or high/ mid rca's only when the sub/ low rca's are turned off.

As soon as you turn on the sub/ low rca's the H.U. automatically high passes the front/ rear rca's somewhere around 80 - 100 hertz, there's no way to stop this.

When I turn on the sub in the speaker menu it really kills the low end from the sls's.

I'll be happier when I put a H.U. that isn't fighting with me over crossover points.
