[Wanted: K-79 with lenses]

Need complete K-79s and lenses or K-792s with lenses for rebuild of four KP-250s. I also need all the port tubes for all four speakers, so a total of eight.

So are you ready to take the plunge at home?

[Rebuild of kp250's]

I have 4 of the KP250's and I have been reading up on these but I need some clarification.  I know that the tweeters should be the k79k but if I am purchasing all new tweeters and lens's will they all fit, or rather is there only 1 size lens that would come on a k79?  I was planning on looking on ebay for these.  I also need a diaphragm for one of the mid ranges.  I have read that these came with titanium diaphrams but I wasn't sure about that. The last question for now is the ports where removed to put in dual tweets.  What length ports are these and where can I source them or should I just build them. thanks for any help in advance, and forgive me since I'm new to this.
