Default Behringer DCX2496 x-over, better than passive?

I apologize if this question has popped up before in the Behringer thread but it is a lot to search through so forgive me.
I have been comtemplating one of these units for quite some time now. The monitors I have now utilize a Vifa XT and a Vifa P13 in a ported enclosure using a series crossover. (I think the sound is fairly impressive albeit a little lacking in the bass dept.)
Can you get significantly better sound using one of these units over a passive crossover?
One of the concerns I have is how to deal with the baffle step issue. I read that it does have an EQ in it - would this be used to shape the response of the drivers in question?
What's the transparency of this unit like if you are using analog inputs and outputs?
If this crossover is the real deal I would entertain using the Vifa P13 as mid and something a little more robust down below. (good idea?)
I know a lot of questions but I'm looking for some enlightenment here, so any comments or suggestions would help.
Thanks.

If someone stole my passive crossover, I'd probably be thrilled.

If someone stole my DCX, I'd rush and get my shotgun and gather
the posse to hunt him down.

Great thanks for the info.
May I ask then for a suggestion as to where to look to get some answers? Cause your right , I wouldnt want to hand over my hard earned dollars before I feel completely comfortable.
Maybe a link (?) to a particular thread or post(s)?
Most of what I found on it discusses technical upgrades to the unit itself.
Thanks

I gathered you like the DCX
Can I ask you to give me an idea where you were with your system before the DCX with passives and where you are at now?

IMO active crossovers are seen by too many as an instant better solution. They are loads better but ONLY if properly implemented. The passive crossover may have been carefully developed to take a lot of factors into account which a lot of DIYers often miss.

I haven't used passives in 20 years. All analog active.

Moving from analog active to the digital crossover is
the best move you can make because you get alot more
features to allow more tweaking. Look at the feature set
for DCX and compare it to a plain jane analog crossover,
no contest. DCX packs more horsepower to fine tune your
sound system.

Any negatives that may exists are drowned out by the
huge positives.

I am using XT25+ P13WH as well.
Also thinking of getting a woofer for it.
I prefer Alu woofer but it seems hard to go with PP mid.
Maybe SS PAPER Woofer would go with P13WH very well since P13WH sounds like paper cones.

Hi,

I think the question you are asking is of a kind that look much easier to answer than it really is.

I got my DCX2496 some 2 years ago. I was also tempted by the capabilities and potential to try much more crossover variations than before with passive XO-s.

Of course I started out by listening to the unit as a stereo DAC and to figure out if it reaches the quality level sound wise that I was looking for. I was thinking that as I anyway had sure plans to mod it I wanted to do it before I went active with my full system to have a better idea how good the DCX sounds as a simple DAC.

Anyway - it took me some 1,5 years to build up enough power amps and tweak the DCX to satisfactory level before I got my DCX going as an actual active Xover.

***
The current state is that I have a modded DCX that has a 6 channel volume built in + new analog stages for all channels (+Tent clock mod) and 6 channels of ok power amps.

Now I'm finally in a state that I visualized when I got the unit 2 years ago.

Meaning that I can now take measurements of drivers, feed the data to LspCad and then use LspCad to model loudspeaker XO with Behringer modules. Then to print out the settings for DCX - type those into the DCX and LISTEN.

***

The result - well there is potential. A lot of it.

BUT it is also very tricky. To have all that capability to tweak and try tens and tens of different variations even in few hours gets very hard psychologically.

One has to go out and listen to other systems much more often because it is very easy to loose track with all the tweaking capability.....

Ergo

Iwas never really happy with my XT25 - especially whilst tryng to tweak a series Xover etc.
now with dcx its greta - lots of tweaking still to do if I wish
I've tried the Le Cleach implementation with good results.
Baffle step via dcx a cinch...
Cheers
