Budget active crossover options for 2.1?

Hi everyone.
I just finished building a small subwoofer using tangband w5 to go with my markaudio chn-50 speakers.
Now the issue is i need a budget active crossover that is not going to diminish the sound quality too much.
What is the best way to go about this ?
I am open to diy kits/projects.

What about something like this...

As much as i like analog circuits i must admit that this would be far easier to tune.
The thing i don't like about these cheap dsp boards is that they take analog input, convert it to digital and then back to analog.
I want to know what you all think about something like this, I am afraid that it is going to ruin the overall sound quality.
Also i don't want too much latency since this setup is going to be used for both music and movies.
 
There's also active adjustable analog filters like ESP State Variable Filter .
Yes i know, but i really want a 24dB/octave filter, i already tought about building ESP project 09 but the pcb is kind of expensive, I could have a go at design my own pcbs to suite my needs.
Also after experimenting with some low pass filters i am pretty sure that i knows what frequency i need to cross them over.

The ADC / DAC in the ADAU1701 aren't exactly state of the art but I doubt it's an audible problem in most applications. Adding a better ADC should also be easy, reducing noise/THD by about 10dB
 
Thanks for all the info, i think i am going to go with the tsa1701 dsp option at least temporarily.
I really like analog but i first want to figure out the crossover point that sounds best, i will probably upgrade to either fixed analog filters or higher quality dsp later.
Money is tight right now so this will do for now.
