I just scored a set for what I think is a REAL good deal. I just got the midbass's, not the mids/tweets/crossovers.

How would these rate against, say 7" revelators/Ushers/etc? They will be in an active 2 way for now until I can make some kicks for my Maxima and get some 4.5" mids to go in them; then they'll be active 3 way:)

Anybody used them?

EDIT: These are not the "i" s.

I just got these put in; damn they sound better than the Alpine's I had in there before. I am still breaking them in, but right now they go down to 50hz no problem, but I think I'll be crossing them over around 65hz via my DCX-730.

I thought these were fairly popular; no one's used them???

DLS's on the right, obviously...

Revelators? No way. The Revelators are the FINEST, without question, mid-bass I've ever heard. One driver comes close, as far as I am concerned, and those are the Adire 6.8's. The linearity of the Adires is actually a little bit better, especially down low.

Utherwise, those sure look a LOT like a Morel designed motor structure to me... The treated pulp cone remindes me a lot of Seas or Scan-Speak.

If I had to say anything about them at all, I'm betting that, without even HEARING them, they'd spank the Alpines... :)

I'd consider a SLIGHTLY smaller mid-range, like a 4", rather than the 4.5 you said you were/are considering. It'll integrate beter with a good tweeter. For a 4.5, you'll have to lower your crossover frequency to the tweeter too low, this will compromise the tweeter's power handling capability.

^ Ah, that's good info. The DLS set actually came with 3.2" mids IIRC, and a tweet; but as I said all I got was the midbass's.

Yes, they do spank the Alpines, no contest. Not even in the same category. I don't think I should have even let them be in the same picture :)

I think I am going to go with Seas 27TFFNC/G's, or Seas 27TAFNC/G's for the tweets. I haven't decided on which ones yet. From whay I've read, the 27TAFNC/G's aren't too harsh for being metal domes, so I am leaning towards them. I am just up in the air on my mids.

But I still can't wait to get these Iridium's broken in so I can crank it up, man it's nice to have quality equipment for once...

NOO!!!

No metal domes! GAH!!! No matter who makes them, you'll be able to tell a metal dome. Even Focal (who makes some of the most highly regarded metal domes in the world) don't sound all that nice. No, seriously, look into some silk domes, I think you'll be FAR happier, in the long run. Depending on the outlay desired, the D2905/9900 Revelator (a silk dome) can't be beaten, at any pri... well, a true ribbon will beat it, but those are THOUSANDS a pair... Go for the Revelator mid to top it off (the 12M-4631G), and you'll be building my desired system, BTW...

It's a fallicy... Crank 'em now! My volume control is WFO from the day I install stuff! It's like breaking in an engine. Wide open is better for it than babying it!

Well, before I can go cranking it, I have to get it tuned. I think my DCX is clipping now that I have played with it again, cause I know the mids shouldn't be breaking up at at 3/4 volume level now. I still have to play with it some more.

And the Seas 27TFFNC/G's are textile dome's, supposedly they are way more layed back than the metals...

My H/U is an Alpie CDA-9831, that feeds into my PPI DCX-730(active biotch!), which then runs the front stage and currently the substage as well. No rear-fill as of now...

The 2 mid's above are powered by a MA Audio Hard KORE 2ch [URL="https://www.maaudio.com/product.jhtm?id=3&cid=12"](this one)[/URL]that I have had for a year or 2, so it will work for now. Not on the same level as the mids, I know; but the budget won't allow for any Zapco pieces right now. When I mess with it tomorrow, I am going to try and bridge it and run the mids paralell since they have single 6ohm coils each. This should load the amp at 3 ohms. It should be ok, as the amp is advertised as 1ohm stereo/2ohm mono stable. We'll see...

As for my crap tweets; I may try and run them off the H/U for now, or I also have an Orion Cobalt 2ch [URL="https://www.dealtime.com/xPF-Orion-Orion-CO100-2-200-Watt-Power"](Like this one, but a CS not CO; same power & s/n ratio though)[/URL] that I got for free brand new I may try and power them with for now. The Alpine has x-over and t/a, so I may not need anything else on the tweeters for now until I get some better ones.

As I said, no rear fill; but the sub stage is alright. It will definately keep up with the front :). 2 Earthquake DBX-12's mounted in a custm ported box I built using WinSD, tuned to 31hz. I am alos in the process of making a face for the box so that it looks like part of the trunk; I know it looks like ass right now, but it sounds ok for what the subs are. The whole inside of the box has been braced, sealed and coated w/ rubberized undercoating, for what it's worth. There's just no sense in me doing up the whole trunk now, when I want to get good amps and put them on display underneath the false floor I'll make when I get them.

The amp I have pushing those is the only piece of equipment I really HATE having in my car. I know it's not putting down that much power.[URL="https://www.crutchfield.com/S-407lgg11F5G/App/Product/Item/Main.aspx?I=037A8000T"]Audiobahn A8000T[/URL]. I got this off a friend for cheap when he needed money, so it's what I have for now. "Supposedly" 800w RMS X 1 @ 2ohms, which is what I'm running it at; both single 4ohm 12's in paralell. I have had it for almost 2 years now and it has yet to shut off or give me any problems. And I push my systems. But I know it's garbage, so no bashing needed.

Just kidding ya, but be careful... (referring exclusively to the "active biotch" part) Lots of us have systems that'd dump yours. posted_image

Sure we probably spent more than we had to, (guilty as charged) and more than you did, but still...

That's not what I was trying to get at when I posted that, but thanx posted_image

All's I meant was that I thought it was cool to finally be active and get away from the crap I have always run. And it's not like a DCX is high-dollar gear anyway...

Me= not going to try and compete w/ peoples on here that have way more invested in the systems than I have in my car. Not to mention ya'll do it for a living...

I did some tuning today; got rid of most of the hiss from the DCX-730 and all my alt wine is gone now.

I must say, I think time delay is about the most important thing I did today, aside from getting rid of the noise. I used my subs as the farthest drivers, and delayed everything else to them; now they are integrated much better and the bass comes from all around and not just from behind.

I think I have the x=overs and eq about right, but I may still need to d some more; I can't really tell becuase I had the volume up loud and now my ears are al little off :)

Tuning is where it's at, kids...

I wired up my Iridium's today, and bridged my 2ch MA Audio HARD KORE amp, set my sensitivy/volume settings on my DCX730, and adjusted my amp gains.

Good news is is that I got rid of all my Hiss and alt wine, bad news is now what I turn it up really loud, the sound cuts out from the front speakers. The subs keep playing, but no high end???

The amp says it's 2ohm mono/1ohm stereo stable, so I should be good there.

Any ideas? The amp specs can be found here if needed

Sounds like the gain is too high or the impedance is too low. MA Audio is not known as a high-quality brand so the specs may or may not be accurate.

This I can understand, and was my first thought; however, why would it no do it with the other mids I had-they were 4ohm each and I ran them in paralell for a 2ohm load? Now the amp should only be seeing a 3ohm load w/ the 2 - 6ohm drivers...

Well, I figured I would nip this problem in the bud and get another amp. If this thing won't handle a 3ohm load when it is advertised as being 2ohm mono stable, then IMHO it is junk.

I am in the process of purchasing an ECLIPSE XA4000. When it gets here, I will bridge 2ch to each Iridium and let them eat. That way I can still keep my stereo sound and feel the power...

That should fix my amplifyer troubles posted_image

Indeed... Basically the same thing I did with my Adires, when I bridged an Alpine PDX4.150 to a pair of them. "Let them eat"... I like that! posted_image

Yeah, I usually use that when referring to our big motors when at WOT in our pulling trucks, but I thought it would apply here as well.

Can't wait till I try out my Iridiums. I have the 6.2 set but will be going active. I was going to power them with the DLS A4, but traded the amps. I'll probably get the 3 channel DLS in the future when I go 4way. I heard the Iridiums before, but compared to the Revelator's, theres no question about midbass, the Revelators wins hands down. Not saying the DLS isn't a great mid, it is, very warm sounding. Can't wait to get mine hooked up.

^^^ Cool, post back when you do; I'd like to hear someone else who has these. I haven't really gotten many reviews about them so far...

My XA4000 should be here by Thursday, and I have the whole week off after Tuesday so I should be able to get everything wired and put in by the weekend.

Can't wait!
