Of course the internal wiring will have an affect, in some tower speakers, the wiring runs several feet in length. Take a look at my DIY Speaker Cable Note, it is at my web page, the URL is in the FAQ for this board. MAterails quality matters, as does the overall geometry. I recommend a crosso-connected coax made from 89259. It has a very neutral sound, crisp highs and tight lows, and can be used for both the woofer and the tweeter. CAT5 wiring is also an option, just be sure to get the god stuff, the plenum grade teflon insulated, with bare copper solid strands. My note contains info on which Belden part numbers to use to be sure to get the good materials. I would advise against mixing the woofer and tweeter cables, as per Thorsten's FFRC recipe, as this will create crosstalk between the woofer signal and the tweeter signal. Isolate the two cable runs from one another physically. Be sure to either twist the two CAT5 cable assemblies around one another for the woofer, or to use the built-in pairing that the CAT5 cables already have (solid color vs. striped) and double them up physically. For this short run inside the speaker, this will minimize inductance, and should not present a difficult load to any amp (which is why Thorsten recommends the "all wires in one bundle as one polarity" approach). One thing to keep in mind for internal speaker wiring, is that it will be subject to a lot of vibrations, so homemade speaker cables should be firmly held together, as with heatshrink (minimum quality level recommended is polyoelfin, do not use PVC, see my note) or plastic cable ties, or other non-metalic means. The idea is to minimize any cable vibrations, and to keep the two polarities of cable signal as fixed in their physical relationship as possible. It would not be overkill to install them in a hose or vacuum cleaner tubing filled with sand to minimize vibrations. These are things that you as an individual can do, that would be prohibitive for a manufacturer, due to the labor cost factor. If you upgrade the wiring, it would also make sense to upgrade the caps, at least the tweeter caps. Replacing them with a very high quality cap such as Hovland or Kimber, or MultiCap, etc. would provide some increase in clarity and definition. This, as well as replacing the wiring could change the voicing of the speaker somewhat, but the wiring and caps are a much safer bet than any other portion of the crossover. Jon Risch
