Hello friends, this is my first post and i really need your help.I have just finish my new speakers with 1 x woofer eminence Delta 120A ,2 x midrange celestion TF0615MR(close back) and 2 x tweeters Beyma T 2030.I have a big problem with the crossovers, can you help me found out what crossover should i use for it ? I use an old crossover from my previous speakers but the result is terrible.I cant use the softwares -i dont understand those-is there someone who can design a crossover for me and what componets should i use? I am given you specs from the drivers :12" Woofer
400 W RMS,8 Ohm,54 Hz - 5 kHz 6'' midrange 97 db, 8 Ohm,50 watt rms,500-5,000Hz Tweeter Power: 15W
Impedance: 8 Ohm
SPL: 95dB / W / m
Extremely high quality high-end tweeter from 2.5 kHz Thanks!!!!!

An externally hosted image should be here but it was not working when we last tested it.
Um,
May I politely say you have overstepped your boundaries? Your crossover might as well be put on the back burner as there are concerns that need to be dealt with before anything else.
Since I am a Moderator here, there is no time to deal with where things should have been done to start with and I hope the diyAudio members can help you salvage something from this.

Let's first ask some obvious thing: How did you come up with this design?
First off, two tweeters is not something that is usually done, specially because it will give all kinds of nasty lobing effects. In your case the midrages and tweeters will be a lot louder than your bass.
Your old crossover will not work. Those things are specific to the driver units and design of a speaker and can rarely be reused. A new crossover needs to be designed to have any change of making this work.
For that you should definately loose one of the tweeters. Next up, the specs you list are not at all helpful in making a crossover. You'll needs measurements of the frequency response and impedance to make an optimal crossover. If you don't have to tools for that it will be a lot harder, but the crossover experts can probably help you there much more than I can. I guess the dual midrage and single tweeter can be mated and if L-padded down a bit should also work with the woofer.
Another question: did you calculate the box size and port sizes? 97Liter tuned at 52Hz should be okay. It won't go very deep though.. It's not really a sub driver.
BTW, the cabinet looks very nice. What kind of material is it?
