JWATS Posted March 1, 2018 Share Posted March 1, 2018 All, I contacted Bob Crites about rebuilding my crossovers, I have the KM 4 model, which I thought was completely identical to the KG 3.5, but sold only through the Military. Bob responded and said he heard the capacitor values might be different: For the crossover, according to an old email I have from a customer, he found the crossover to actually have different values of at least one of the capacitors than the KG3.5 schematic shows. So, just don’t know if his was a fluke or if the KM-4 actually has a different crossover. In any case, I think you would have to read the capacitor values to get the right stuff sent to replace them. Does anybody know? Or have experience with the improvement I can expect by doing this? Thanks in advance John Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted March 1, 2018 Share Posted March 1, 2018 Bob is of course correct. The best thing to do is read the values off the caps on the boards you currently have and replace with the same value. If the caps are 20 to 25 years old you'll notice better clarity in the mids and highs. It should be a noticeable improvement. Quote Link to comment Share on other sites More sharing options...
JWATS Posted March 1, 2018 Author Share Posted March 1, 2018 Thanks so much, I have a question about getting access to the crossover..it looks like an odd screw head, is there a tip meant to be used? I've attached a picture Does not seem to fit a regular Philips head Thanks and sorry to be a nuisance, this is all new to me Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 1, 2018 Share Posted March 1, 2018 It looks like you could use a phillips, but it is designed for square bits. You can get them at Lowes, HD, Harbor Freight, etc. A lot of cabinet screws us a head for square bits. There are a LOT of sbapes that are used. https://en.m.wikipedia.org/wiki/List_of_screw_drives Bruce Quote Link to comment Share on other sites More sharing options...
dtr20 Posted March 1, 2018 Share Posted March 1, 2018 Are all the screws like that? It looks like the screw head is stripped out Quote Link to comment Share on other sites More sharing options...
JWATS Posted March 2, 2018 Author Share Posted March 2, 2018 yes, the are all like that Quote Link to comment Share on other sites More sharing options...
avguytx Posted March 2, 2018 Share Posted March 2, 2018 It's just a square tip versus phillips. They sell them at Lowes, Home Depot, possibly Ace Hardware, Harbor Freight Tools, sometimes Wal Mart, etc., etc. Quote Link to comment Share on other sites More sharing options...
JWATS Posted March 2, 2018 Author Share Posted March 2, 2018 Wondered if this head would work..seems like it fits Phillips/squareEdit The Phillips/square screw drive, also known as the Quadrex or Pozisquare screw drive, is a combination of the Phillips and Robertson screw drives. While a standard Phillips or Robertson tool can be used, there is also a dedicated tool for it that increases the surface area between the tool and the fastener so it can handle more torque.[46] Quote Link to comment Share on other sites More sharing options...
Alexander Posted March 2, 2018 Share Posted March 2, 2018 Looks too eaten up, IMO it is just striped out as mentioned above. All you will need is to get an easy out at the hardware store of your choice. The screws themselves are not anything special and are nothing more than a conventional wood screw.

001 Posted March 2, 2018 Share Posted March 2, 2018 unless klipsch used a differet screw in the KM speakers, that is definitely a stripped out phillips screw. the spreaker wire/x-over & drivers use phillips screws in every klipsch speaker i have seen from heritage to KG to reference. & that is a pretty bad stripped out head, these screws are just short wood screws into MDF or plywood, cant imagine how they would get that stripped out. before buying some specialty screwdriver/ bit i would suggest trying some different size phillips to see if they will fit better, or what ive done on lots of stripped screws is to get a flat blade screwdriver that will grab 2 of the legs & that should be enough to carefully remove them, they should not be that tight. then go to your local hardwre store & get some new screws to put it all back together. 1 Quote Link to comment Share on other sites More sharing options...
avguytx Posted March 2, 2018 Share Posted March 2, 2018 If you have one, you could take a Dremel tool with a metal cutting blade and cut it so a flat head screwdriver could take it out. I've done that plenty of times through the years. And as mentioned, try a different Phillips screwdriver head. Not sure if you're trying that with a #1 or #2 tip but that could make a difference. But again, if you're close to a hardware store, just see if they have some square bits; they aren't that expensive. Plus, you can buy new Phillips screws while you're there since you're going to replace them anyway. It's not a wasted trip killing two birds with one stone.
