ok heres the deal.

i plan on having a pair of:

vifa xt tweets
peerless csx 5.25 mid
and morel mw266 8"

problem is i need a crossover that will be able to handle these speakers.

i can use my current amp to filter sub freq's to the 8" mids if they need it.

BUT i want to BANDPASS the peerless csx and highpass the xt at around 2.5-3khz

anyone know of an active crossover that can do that at 18db or 24db slopes?????


(id like to keep it cheap if possible... but if i must go passive then i will)

eclipse cd5000
DD 9515
4.25 cu. ft box 83 sq inch port.

if u port it, bass will come

Chances are that a decent active crossover with those slopes, even if expensive, will cost you less than a 3 way, well designed passive with decent components.

According to the audio control website the 6xs is a 2 way crossover. So it will only have a low pass and a high pass---no bandpass. But, imho, the chips you have to use to tune an audio control processer are a PITA, and to much hassle. You either end up guessing at what points to use, or you have to build a billion chips to test with.

I would look at the Coustic XM6. It seems to be close to what you want. Phoenix Gold use to make one--I believe it was the M3 something or other.

You will probably get more choices by buying 2 2 way crossovers and daisy chaining them. Something like a pair of Coustic XM-3's (although they "only" have a 12db slope---which is probably fine).

Pioneer has the CD-635 and 625. The 635 is a true 3 way and the 625 a two way. If you daisy chain those two, you would have a sub out, a midbass bandpass, a midrange bandpass, and a high pass. All at 12dbs.

I'm not up 100% on the crossovers out there today, but looking on ebay under the crossover section made me want to cry at what I saw.

You might be better off saving up the ~$675 and going digital with something like the Alpine H701 set. It will give you everything you want and more.

Other than that, to be honest, I would just go with a pair of XM3's. Great crossover--no noise, basic, easy to use.

On your list of wants---get continuously variable crossover points. Anything else is a serios PITA, and will end up not being flexible enough to keep for the long run.

No disrespect Andy but your wrong about the 6XS. Its a 6 channel crossover....in fact it has 6 channels in and 8 channels out....2 of those are bandpassed. Heres the link,

http://www.mobileaudiocontrol.com/product.asp?Product_id=18487

Im new to the SQ thing but heres how my stuff is setup:

tweeters: 3300 and up
4" mids: 720 and up
6 1/2" Mids: 90-720
18" subs : 20-90

this is all done with the 6XS.....i actually made my own modules because the stock 90-250 didnt go high enough for my tastes for a door mounted mid. I bumped it up to 720 and it could probably go up a little more if a SQ guy tells me it should be like that. I dont know, i just know my system has never ever sounded so good since i put the DQS and 6XS in there.

Where I got the information from was that website---look at the key features it states:

quote:
State-Variable, 24dB per Octave, 2-way Active Crossover
Inputs and outputs don't really matter (as to if it is a 2way or 3 way). The XM3 has one set of inputs and 3 outputs. But the outputs are one low pass and two high passes. That's a two way crossover. A true 3 way has a bandpass for one channel.

You actually have this, so if it has a bandpass (the information on the website is wrong), and it would work for him.

I still wouldn't recommend it because of the chips. I think continuously variable is far superior in the flexibility department.

But again---if it does have the bandpass--then it will work for the original poster.

like i said, no disrespect im here to learn from you. If im wrong, school me! I guess i didnt know there was a difference between 6 channel and 6 way....i do now. Anyways, all my eyes saw 6 in, 8 out - good to go right? [Razz] [Big Grin] Im still trying to figure this quality mids/high stuff out.....ad this to the list. So if you took a pair of 6XS's and linked them together you could achieve more than one bandpass like that right?

I found the owners manual finally on the 6xs. After it crashing my computer twice trying to open it, I finally got it.

With 6 channels of input you have a sub out, 2 (or 3) highpass outputs and one extra low pass output.

In 2 channel mode, you have a sub out, a bandpass out, and a highpass out. The diagram showing this manner of operation for some reason doesn't show the rear output highpass being used---but it appears as though Meade916 uses his--so it is possible. That would give you a sub out, two high passes and a band pass.

That would work with the original poster. Still uses those PITA chips though.

Even with this, I'd still save up and buy the Alpine H701. It simply blows away anything made by Audio Control--in terms of flexibility.

Imagine variable crossover--for every channel, variable slopes---for every channel, adjustable phase--for every channel, time alighnment---for every channel, mono OR stereo 31 band graphis EQ--for every channel, parametric EQ--for every channel, etc. For the price it is a very hard piece to beat. When you step up from this, you are heading to the Alpine F#1 piece, a drive rack piece, or one of the Rane big dog pieces.

Try the Kenwood KEC-600 if you can find one. It has high-pass f+r, midrange band-pass f+r, midbass bandpass, and sub. and 6 ch inputs. The only reason i use instead of Audio Control is that the x-over points are variable and the 6ch input. As much as i love Audio Control those x-over modules are a pain in the a**.

Coustic xm-6. Nice unit at a good price and I haven't had any problems with reliability. I even messed with an old xm-3 that looked like it had been beat to crXp! It didn't miss a beat.

Andy- you've piqued my curiosity. I'm going to have to research that Alpine unit.

Also, if memory serves me correct you can use a coustic xm-3 to do a highpass out, a bandpass out and a sub out. (and it's fairly inexpensive)

Go passive, I built my first sets of crossovers several months ago (bandpass for midbass and high/low for mid/tweet) and it was a great learning experience as well as a lot of fun to do.. I think I am going to piece together nice components like you are and do a 3 way passive next time I install mids and highs in my car..
