First, you are better off with a 12" or 15" pro woofer rather than dual 10s in a 2.5 way. Sensitivity will be similar or better with better directivity and greater simplicity. Beyond that, with a wide baffle you don't need much BSC so the .5 way woofer is wasted.
Second, why go active DSP with a budget component design? You will get more bang for your buck at that price point with a passive kit. Something like a 3 Pi or the SEOS-12 with 2512 LTD just mentioned. IMO, DSP starts to make more sense with more expensive components or your money could be better spent. With a 2.5 way you will need 6 channels of amplification for a 2-channel setup...and it will have no performance advantage (in fact a slight disadvantage) over the aforementioned kits.
Third, as you can see, crossover design, even with a DSP is not trivial. Without some guys chiming in about lobing issues, you would have had a mess on hand that no DSP would solve. The basic principles are the same whether passive or DSP and you simply don't understand those prinicples...yet. Of course, anyone with basic physics and math knowledge can learn about crossover design, but until you understand what you don't know you will have some rough treading.
I'd suggest taking a step back and think about what you really want. Picking out some random drivers and saying you want to design around that is the wrong approach. Starting with some general goals is better. Do you want to learn to design your own? Or do you want a kit? How big? Budget? The SEOS-12/2512 kit would fit all of your criteria...unless you really want to design your own speaker and that requires some self-education.
I really appreciate your input. My feelings can't be hurt, and if you read my opening post, you'll know I don't mind being called an idiot.
1. I don't want to purchase a kit (I won't learn anything that way, and I want to build something somewhat unique)
2. I understand what I don't know because what I do know is just enough to be dangerous =)
3. Yes, I want to learn speaker design
4. I already have the DCX and the amps, so going active was obviously cheaper and didn't require me to learn anything about building a passive crossovers
5. This started because of what I read about the SHO-10, and I noticed the components were cheap and common
6. The whole point for starting a thread was to throw a "shot in the dark" idea out there and for more knowledgeable people to shoot holes in it. I've learned a lot doing this
7. What do I want? I want to build speakers with greater clarity and dynamics than my current Definitive towers. Budget, say $300-350 per speaker for the LCR
That being said, how many of you on here use the Soundeasy software? Everything I've read says it's difficult to use but very effective once you know what you're doing.
