2005 Eclipse 8-volt unit crossovers

[unrealii 10+ year member]

Well, unrealii, your "high doubt" appears to be wrong. Unlike the 2003 and 2004 models, the whole DSPs in each of the 8-volts are now entirely different from each other and the crossover is definitely different as well. The question is - what about it is different and is the 45 as limiting as it appears it might be (one crossover point splitting high and low pass).

I stand corrected. I played around with 8445 yesterday for a few mins and confirmed you are right. Best thing to do is to call eclipse and ask them.

Why not just buy a decent outboard x-over and save the headaches.????? I have never used an onboard x-over and I've never had these problems in which you speak. Just my $.02. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

1) Because the Eclipse crossover happens to be a very good one.

2) Why spend the extra money on the external and RCAs?

3) Why risk adding extra noise in your system? There is a lot to be said for simplicity.

So good that you're having all these problems??? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif Doesn't sound so good to me.

2) Why spend the extra money on the external and RCAs?

A decent outboard x-over woudn't be that expensive and you would only have to buy it once if you buy one that will expand with your system. RCA's ?? Come on, all you would have to do is mount the x-over in the trunk since you're already running rca's back there and insert the x-over in between the deck and the amps so you would only need short runs from your x-over to your amps.

3) Why risk adding extra noise in your system? There is a lot to be said for simplicity.

A quality component wouldn't add any noise to your system unless you don't know what you're doing. Audio Control's units have selectable ground loop isolation so you can set it to where there is NO noise at all.

To each his own man, there may be alot to be said about "simplicity" but if your "simplistic" system has adjustment limitations than there is alot more to be said for "versatility" and "adjustablility". Just my opinion.

Cool, Adam, but the system doesn't have limitations unless I buy the system, right? That's why I pose the question. I don't think you read the entire thread.

Now... follow the model numbers: The 8455's crossover, as described on this board previously, is extremely flexible ("versatile" and "adjustable" for an incredible many points and slopes, high and low, for ALL channels), and I know from experience that the quality of the Eclipse HU crossover is excellent based on my 8443. My issue, however, has been simply wondering how the 8445 compares exactly to the 8455. If it was the same, or close, in feature and function with respect to the crossover, I could then simply save myself $100 and buy the 8445.

I'm confused about the 8455's Pro mode 4 speaker crossover setting. Does this "4 speaker" setting actully mean a 3 way component set along with a subwoofer? If so, can I set the crossover frequencies for each woofer (tweeter, midrange, midbass and sub) independently, at any frequency and at any slope ranging from 0 ,6,12,18,24dB? The 8455 has a 7 band parametric EQ, correct? If so, could someone post specs on the eq? Like max/min attentuation/boost, corner frequency, bandwidth? Hows the time correction? Does the headunit offer phase control?

If I'm going to pay 600 dollars for a Head unit, it better damm well do everything I need it to do, short of amplification. Basically, I need a good processor to set up a 3 way system. An outboard crossover/eq (like the altomobile Drive 30) would give me EVERYTHING I need as far as processing goes. I'd buy it if I could find a cheep headunit with all the features I need.

Edit: also, is there a gain setting for each woofer (tweet, mid, midbass, sub)? So that, if need be, I can match sensativities. (especially since I don't think most amps have gain adjustment for each channel, I'd need 7 channels of amplification).

An outboard is still higher quality and simpler to use. But like I said in the earlier post....to each his own. Have fun.

I disagree with you on both counts. Potentially, each type of setup has the ability to outshine the other. But, yes, to each his own.... that said, I'd happily install a free Audio Control DQX if you have one layin' around. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

This is called a "thread high-jacking," JonJT. You'll get more attention if you start your own new thread. Cheers. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

To the contrary....I just went from an external xover (Coustic Design Reference DX-28) to using the internal xover in my 8053, and I'm actually happier with the 8053's than I was when using the external //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif And the DX-28 is one of the more versatile(sp? it's late..) external xovers on/that have been on the market.

You make a good point but quality differences vary from one scenario to another. I've noticed most of the decks with crossovers don't allow enough flexibility, such as not enough not enough crossover frequencies or slopes. Which is why I've always gone with outboard. My last one was an MTX LSX-2 and it adapted to ALL 3 different systems I used with it. NOT trying to say you shouldn't use your deck's crossover, but I just think that looking for a deck just for the x-over is silly when you can broaden your choices when you don't have to worry about what

characteristics a certain deck has.

Where's the "Hi!, I'm a first time Eclipse user and here's my review...." review? //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Did you have fun with all the spagetti's behind the unit?hehe...

It's alright, I'm going to get a manual.

First of all, Adam, which is it: "An outboard is still higher quality and simpler to use" or "quality differences vary from one scenario to the other?"
Second, apparently you simply haven't used/heard a truly good crossover within a head unit. If you had, you would have left your assumptions at home.

Hey, sure, I could go looking for other head units, but Eclipse is, by far, the best head unit, with warranty, I can buy locally and I happen to like 'em. And, I know, that one of these head units - if not possibly both - have an amazing crossover quite suitable to my needs. If not the 8445, then the 8455 (check out the great review on this site). //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

Well, you apparently can't comprehend what I said. Quality differences vary because not all outboard crossovers and onboard crossovers are created equally therefore results vary. Is that clear enough yet?? //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif So please don't take what I say out of context, you know what I meant. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Premier DEH-P920R, Premier DEH-P930, and Premier DEH-P860MP are head units I've owned that had crossovers within them. The only one I've used onboard was with the 920 and the 860. I used the on board on the 920 until I purchased my LSX-2 and the difference was night and day. The 930 wasn't much different than the 930 so I never tried the onboard with that unit. When I purchased my 860 I thought I'd give it a try in Network mode and wasn't impressed so I went back to using my LSX-2. But hey, ask others on the forum what THEY think of their onboard crossovers for the 860 and I bet they'll say they are decent quality. I just don't think ANY onboard crossover can match a high quality outboard. That is all I'm saying.

Thats cool man, I already said "to each his own", remember?? Just remember that you never know what you'll like the best until you try a few different brands.
