Phoenix Gold Phorum

All I have to say, pardon my french, is HOLY FUCK!!! I just went with a ZX-450 ACTIVE on my Polk SR6500's and they sound UNBELIEVABLE!!! I had chills run up and down my spine and tears in my eyes they sounded sooooo good, that much of a difference! And this is without any time delay or eq'ing! My soundstage is HUGE, DEEP and WIDE! Drums sound FAT! OMG, why oh why every sq nut doesnt do this, I have no idea...

I have the 9887 running active also but my Pro60's don't sound any different just have more tuning ability for my truck than with the passive crossovers. What settings are you at?

I am crossing my subs at 63hz w/ a 24db rolloff, the band pass on my mids~ crossed with the lows at 63HZ 24db, up top 3.2Khz 12 db roll off (stock is 3k, 12 db roll off). I am crossing my tweets a touch higher than factory, 5k w/ a 12 db roll off (stock is 4.5k w/ 18db roll off). These settings really allow me to hammer on my drivers! I am telling you, no joke, the difference is NIGHT AND DAY in terms of soundstage and depth! I cant wait for my RSDc's and Imprint!

i hear yeah- i recently put my tweet elites on the front of my ti500.4, then the mids on the rear of the 500.4( bandpass), pushed the mulitplier in by 10 for the tweets, thats how i found i had a 6.5 elite mid where the cone was seperating from the rubber surround-i know its amazing how much the xovers seem to diminish the output!!!! now, its like my mids came alive, i seem to be truning my lpl-44 down more, to help the subs blend in better

Wow, 5K is pretty hight for the tweeters. I have mine at 3.2K at 24db. You could most likely run yours lower if you cross them at 24db.

Ya, I played w/ the cross lower, it dirtied things up waaaay too much. Polk crosses them stock at 4.5k w/ 18 db, so im not too far off w/ 5k, 12db. Its funny, after playing w/ crossover points/slopes for a couple hours, I wound up so close to the stock points it is uncanny!

Oh ya, I have the crossovers completly bypassed in my amp, 100% deck crossovers...

im talking about active with the internal xovers works too tweets mulitply by 10, then the mids at bandpass- i believe this still rolls them off at 24db

how long u had ur zx450? i bought mine when they first came out like over 10 years ago!!!! mine has no output, ( lent it to my nephew) , and he ruined it, ive just been lazy about sending it in

Thats kinda what i was thinking...

Yeah, active is the only way I go also. Some would say passive is just as good, but I prefer active any day

soth, i keep hearing alot of you guys saying u use idq, i know nothing of this company, can you give me some info, or a site to checkout-thanx Christian

Sure Christian. IDQ is Image Dynamics, they are mostly popular for their excellent SQ speakers. Keep in mind for more money there are other speakers that are better, but for the price they are really good.

ID is known for the sound stage and quality especially with their HLCD's. The CD-2 comps are amazing, but 1000 bucks a set is pretty steep though. I've got the CD1's and I like them and they didn't break me

Anyway, I would like to see a review comparing the new IDQ with the RSD'c. The pro's and con's with each. The RSD'c are much cheaper than the IDQ v3's. See, i'm not wanting heavy bass, just really accurate notes that the sub can produce.

Hope those links help you.

cool deal, thanx

Anytime Christian.

I have the 2-ohm chamelions front stage and rear fill.. and like them a bunch.. only thing is the cones can come dirty or get dirty after a while.. but easy to clean out. If you use as componants I dont believe that is so much an iddues as the tweet isnt secured in the center as with the co-ax setup. Just wish I could get a lil more mid bass.. Thinking if I had some custom baffles.. that wouold do the trick. and perhaps some deadner on the rig.

Passive is for pussies!

















J/K!

Once you go active, you will never go back!

I did

It all depends on the quality of the passive XO...

Once you've heard martin kruit's passive install, you'll never go back

The exception proves the rule my friend!

i've always been active since i can remember, just can't beat it you know when you have got it right as the music becomes emmotional, that's what it's all about!

Here here! Emotional, great description! Its funny, all these years messing w/ all the diff seps I have owned (nak/ads/pg/polk/infinity beta,etc), the sound I have been looking for was there all along, just being wrecked by the stock passive crossover networks! Crossing my seps active has doubled my soundstage width and depth and now my SR's paint a picture when listening to music, no joke, I can now "see" the band! Drums are so much more alive, vocals are now very solid and the freq response is so much flatter. Active or nothing baby!

oops, double pump

I have started with passive (that comes with component speakers), then went active for a good number of years. Yea I agree when I first switched to active, the improvement was extremely noticeable. Same feeling with flogger why the hell didn't I do that much earlier.

1-2 years down the road, I got everything dialled in and there was nothing much in the crossover point, slope and level matching that were changed because the tuning is more or less there for my liking. Occasionally there were some equipment swapping for a "sound" change, but nothing major on tuning really.

Then suddenly one day an idea came. Since the crossover point and slope were basically fixed, why would I need the additional amp channels ? I would have built a passive myself with the known suitable xover points for my car and save 4 channels of amplification (am running 3 way front), 2 pairs of RCAs and a fair amount of speaker cables. Not to mention the space saving in the car and less strain on electrical. But those were just part of the expected benefits.

The surprise was on switching to the DIY passive I made myself, I was in love all over again ! Why didn't I do it earlier I thought. The same feeling when I switch from stock passive to active a few years ago. Stock passive is just not suitable for every car. And I agree with stipud that the quality of component plays a part in passive crossover.

However, to tune a passive is much harder than tuning active systems. While it is just a few dials away to change xover points/slope/gain for active, a passive needs physical change of components to change the tuning points. That is the major turn off for running passive system. So passive system is not for everybody really. It takes much more time and effort to get the sound right compared to active. But one day when anyone is bored and need to spice things up a little, passive would give you some surprises I bet
