Default PC + sound card instead of a behringer DCX2496

There are recommendations to me about using the DCX2496 as an active crossover + equaliser.

Thinking about it, why do I need a behringer if I have a PC(quiet 2.4 Pentium 4), Brutefir is free, and I can get a quality Delta sound card for 2.5 times less money than a behringer. The future sub would be used to aid stereo music, thus I dont need many channels.


Is there a catch? (I think there is)

I searched, alot of the discussion is over the top as far as Im concerned. Whats this talk abt FIR filters,etc?

Nothing wrong with that AFAICT but I personally don't like the idea of booting my PC whenever I want to listen to some music neither to have a PC where my listening environment is. Furthermore I am quite sure that some people would think that a PC is not producing quite the same quality as a PC would. Depending on your goal and budget it is either OK or not...

I've been going over the same research. Isn't it hard to believe that our powerful PC's don't have a readily available digital crossover solution!

As I said in another post, even my Eclipse car deck does digital crossover w/ a nice little gui interface w/ adjustable slope, etc.

It just seems silly in this day of cheap pc processing power to buy a separate peice of hardware for a few hundred bucks. Let me know what you are finding!

I really want to get into speaker building and it just seems like the entire passive crossover step shouldn't be necessary in this day and age. Maybe I'm wrong .. but after my experience with digital time correction, parametric eq, and digital crossovers in my car I'm sold on the concept of eliminating passive crossovers from the system. Any real reason not to be so sold?

the extra cost and the extra hours you have to work to earn that, is probably an even more inconvenience than the moments waiting for the com to boot up, especially since my com is on most days anyways. Also a major proportion of my music is stored on the com.

Ive seen the thread, but most of it is just debate and some arguments between analog hardware vs digital people. theres another thread thats far more relevent in the loudspkeaer forum: Digital active XO+eq using a PC+soundcards+BruteFIR?

I think the difficulty is in designing FIR filters? A search on google proves me that designing FIR filters is completely out of my scope.

What I need is a brief outline of what has to be done.

After some more research I seem to get the picture. User friendly and ready made EQ/crossover programs use IIR filters, which have problems. There are no such programs made that use FIR filters, which exhibit less problems. Many people here of course, arent satisfied, and try to DIY their way out. Hence alot of the discussion I saw was from people (pioneers if you like) trying to deride programs that use FIR filters right and talking about all this complicated stuff, and thus I had no idea wat was going on. Of course the thought of me trying to design my own FIR software is ridiculous.

Since the Behringer DCX2496 use IIR filters, I might as well use a ready made software program. Either way I lose, and I ll have to wait until some person produces a user friendly FIR software package.

Is this wat is going on, or am I still off the track?

You dont have to write software, just use other peoples (though it still isnt easy).

I sugest you go look at "AlmusVCU":
http://www.ludd.luth.se/~torger/almusvcu.html

Its looking like a good single piece of software for config, creating filters and running them.

omg. Is this for real? This is exactly what I've been searching for. Does anyone have any experience with it? How is the stability / sound quality?

I think you are overestimating my abilities. I happen to have recently discovered the benefits of dipoles and active crossovers, and people have said I can easily do it by using the behringer dcx2496. I just want around the same easy interface/usability(give or take a little) applied to a PC. Its a long way off in comparison to making filters, etc, and the DOS-like command line interface .

edit: something like the kx-project that can support the creative EMU/M-Audio Delta semi-professional sound cards.
