Help me design these speakers please

[pjpoes]

I have a pair of Seas L14 RC-P drivers laying around. They are the aluminum coned 5" midbass drivers. I modeled the drivers using WinISD Pro, and came up with a box size of .25, because it allows me to use the prefab from Parts Express, and tuned to about 45-50hz, in that range. I may have to go a bit higher just because I am noticing that the 2" flared port I wanted to use is almost ten inches long, and that may be too long for this box. Anyway, does anyone see any problems with this design thus far. Seems to work with the software.

I also was wondering about some help in what to mate them too. What would be a good match to these Seas drivers. I thought about doing the Seas mag/alu tweeters available, I thought about the Parts Express RS series tweeter, I also looked at the LPG Ti tweeters. Any other recomendations. I know that, given how low the efficiency is on the Seas driver, I will need to pad the tweeter down with a L-pad network.

Some help in the design of the crossover would be appreciated. Recomendations on what order to go with, possible design aids, etc. Are there any software that can give me a schematic of my crossover design with all the parts, including the L-pad, and if I was to add for instance a Zobel network or notch filter, or anything like that. Though I dont see a notch filter being useful in this design, it might be in others. I have no good x-over software at the moment.
