KLH 5 Crossover resistors

Happy New Year everyone! I'm in the process of re-capping my KLH Model 5 speakers and while I had the first one apart decided (at the suggestion of more than one AK member) to test the resistors. Well, as it turned out, one was completely open, it was a 6ohm, 7watt, 10% resistor. I'm having difficulty locating a source for this type/value resisitor, they are square in cross-section and appear to be a hard, gritty substance, not unlike concrete, in construction. There are 5 resistors in each crossover (my model 5's are the early ones with point to point style crossovers): (1) 6ohm/7W; (2) 15ohm/7W; (1) 5ohm/5W; and (1) 10ohm/5W and all have the same 10% tolerance spec. Any suggestions on where I can find these resistors would be greatly appreciated.
I was also wondering what's the best thing to put inside the cabinets for damping and what any of you who have done KLH restorations have used to seal the surrounds. Thanks everyone!

If you want exact values and don't mind spending a little more, these Mills resistors are actually 1% spec tolerance. I typically use them in my upper end speakers but in the other speakers with the "sandstone" style resistors, I don't change them unless they are out of spec or open. If I'm not mistaken, you can run resistors in series (end to end) to add the values together to come up with what you need in the lesser priced versions.
 
Thanks avguy, I don't mind paying these prices for a few resistors but these Mills resistors seem to only come in 12W values, can I use 12W resistors where 5 & 7 watts are called for? Thanks again, at the very least I now know what type resistors these are!
 
Oh yeah....that extra little bit of wattage won't hurt at all. There's also another place you can order caps and resistors from that I have also personally used in the past for Solen and Mills stuff. PartsConnexion.com has some good pricing and ships very fast, too. Here's the link to their 5 watt resistor versions.
 
Thanks a lot guys, I appreciate you helping me out on the importance of the watt values, most helpful. I have added the Madisound link to my favorits elnaldo, thanks, I may try them on my next project but for this one I ordered the Mills resistors that avguytx recommended and they should arrive today, according to the tracking info. Happy New Year!!
