Any of you ever done an approxiamate 8th order roll off with a cauer elliptical crossover (aka a notch and a 4th order LR together)? I want some monster MB for a small cabinet and am thinking of doing a 2 way with a Dayton 225, but since it doesn't play high and most tweets don't like to play that low I am going to need a seriously steep rolloff on my crossover.

What negative effects do higher order filters have?

[CBFryman 2]

GRRR

You're and idiot.

Im not saying all shops are like that. Im talking about my local shop.

i think u need to grow up and get off daddys computer.and u say im a idiot,i think u need to look in the mirror for the idiot here.

I need to find something better to do to occupy my time when I'm bored off my ass.

Most would have a bad interaction in the stop band as well as create some seriously funky group delay. For instance if you went 8th order by strapping two 4th order filters together; however, this isn't a problem with the Cauer. Basically you take a standard LR4th and add a notch filter chosen to be at the beginning of the slope to give you an approxiamate 40-50db roll off near the crossover point. Since it is still a LR you get the nice transition from driver to driver, but don't have to worry about all the other issues when using two drivers that might normally be better suited for a three way. In my case I want the MB of an 8, but only want to go two way for cost, simplicity, and space. Plus I'd love to have bookshelves that womp on my friends mains. Of course, SPL wise running a tweet that low will be the limitation but designed right they should still get decently loud. And again being for my office, SQ is more important than SPL but you'd probably guess that from me anyway.

oh and you only need 5 components to do it so you aren't fudging your signal up real bad.

[///M5 2,833]

might I add how poorly I did in electronics? most frustrating physics class I took, all theoretical which helps me not. I really needed an applied electronics class, but I think I can still fudge my way through math and thevein's theorem derivations.

im effing hungry

[///M5 2,833]

So I only got 4 hours of sleep last night. I've done that many times before but this time I was super drowsy and did something retarded. Got to school and walked to my class. I get to the door and instead of opening it, I take out my car alarm remote to unlock the classroom door...lol

<{POST_SNAPBACK}>

Did it work

[CBFryman 2]

its phucking raining now. grrr, I need to run agian.

[CBFryman 2]

I just thought of the greatest freaking idea ive ever head in my LIFE!

Jim, if you read this, you tune TL's to FS right?

[vladd 26]

I cant wait for my 8443, finally a manual !

Unlike pioneers, you cant just go right at it and start messing with things, you get cornered in some sub menu and have to shut the h/u off

[JimJ 11]

You don't really "tune" a TL to Fs, if you did that, you'd just have a bass reflex enclosure tuned to the Fs of the driver...

What the TL does is reverse the phase of the rear wave, which gets you the same effect, pretty much

I assume you've read Martin King's website on this, he's the pimp when it comes to ML-TL's and their design...also hangs out on DIYAudio.

[JimJ 11]

I need to:

Take a shower

Clean out the van for tomorrow

Find out how to get to where I'm going

Maybe do a late night burger run in Durham, maybe get shot at, who knows

[topgun 262]

I need some lovin.
