"Crossover Design for New Project"

[westend9]

Following along on this build since I'm attempting a lesser project, using only one 416-8b.
I've had really good luck with a Behringer CX-3400 crossover. My plans are to upgrade to the DCX 2496 when I am a little further along. I had been looking at how to get the same bass reinforcement as AB is trying to do, possibly using a different Altec woofer, ala 421 or similar. I am putting that on standby but I think two 416's would get a guy pretty well there in the bass dept.. Of course, some folks can never get enough bass.
Good luck with your project, AB!

Just a note....if you use one 416 for bass and one for mid bass/lower mid range...the efficiency gain is gone for the passive XO...right?

Yes and no, depends on how you look at it. If you want more bass extension, the 1.5 setup will do that. If you wanted the same flat response out of 2 woofers running the full bass spectrum, you'd have to attenuate the upper range anyway. So there goes the sensitivity.

The only way to keep the sensitivity up is to give up on the low end. That may be a reasonable trade off. All depends on what you want.

(Besides, we all wanna see some 511E/288 plots)...:coffeedrinker:

Me too I'm really looking forward to it.As regards to the LF cab I was kinda waiting for GM to give me some advice on cabinet. But he is alittle under the weather at the moment.I hope he is OK.

]I thought you said you will be running 2x 416s per side. So together a 4 ohm load, right?

I am, 2 416-8B's perside.If I hook them up in parallel it will be 4 ohm in series 16 ohm so how do I keep this all 8 ohm.

Measure, measure, measure. You do need to measure.
I guess I could lend you some gear, if you don't want to invest in your own

Or you can send me a shopping list, Another shopping list just what I need. I think you did tell me on the phone awhile back but can't seem to find what i did with that paper.Thanks Mike !!!

Of course, some folks can never get enough bass.
Good luck with your project, AB!

I'm one of them helps get my feet moving if you know what I mean.I love good clean distortion free bass.Thank You Kindly for the well wishes.After I get the help I need to get this going I will document for everyones reference.If it can help others in the future then that is a good thing !Thanks again

Well I like all Bass, Mid-Range,and top end or HF/UHF But as these speakers are super efficient anyway wouldn't that still leave them pretty efficient with a flat response across the board ??? I will follow your recommendations as you guys are much more versed in XO's than I.

Well, my vote is for horizontally opposed woofers, but this means a really wide baffle for corner loading which in turn opens up the tuning options to include sealed. Otherwise, a three compartment MTM, preferably a floor to ceiling affair. In either case the goal is to minimize the acoustic center distance(s).

If you mean mid-bass only, then OK, but even in typical HE HIFI/HT apps, MI drivers should be avoided like the plague for bass since they audibly distort due to no real linear excursion to speak of.
