Hi, Looking at the speakers you are starting with I question as to whether they are really worth the effort to use in a new enclosure you plan on building. As far as I can tell none are really all that great and probably should be left in the original housing. Some thoughts....I have several speaker systems, some rather high end and costly. It actually surprised me that all of them are two way systems. The huge Altec Lansing (internal volume of right at 200 L) ones are, the Martin Logan Electrostatics are and so on. This sort of tells me that a two way is just fine. Looking at the drivers you have and the lack of crossovers except on the one tweeter indicates to me that most of them are there as a marketing ploy. It is possible that some better performance could be obtained with careful choice of crossovers. But with essentially no data on the speakers it would really be hit or miss. In a generic system the woofers would cross over between 300 and 700HZ, mids from there to about 5000-8000HZ and the tweeters would handle everything above that. These are just rough values, there are many alternatives. It really looks like your woofers are more of a mid bass type and could go up to 1000HZ or so. Since there are no crossovers in any now, I would opt for simple first order 6 db up and down crossovers at about 1000HZ, and 8000HZ. There are numerous references on the web on how to choose the components. They would also indicate that the mid range driver should be hooked up in reverse phase. This would entail the minimum of additional components and be most likely to match the speakers you have. All that said some things come to mind. First I would start fresh with newly sourced speakers. Some very nice systems can be built from plans on the web (see ones on Parts Express in particular). The costs would be modest and you would virtually be guaranteed a quality system. Let us know how it works out.
Good listening
Bruce
