JKent Posted March 3, 2017 Report Share Posted March 3, 2017 Right now there are 2 pair of Model Five crossovers on my bench and a third on its way. This one is a very basic recap and resistor swap. I know some respected members have said the 5W resistors are enough but I've seen burned resistors in a Five and in the similar Twelves so at 50 cents each I figure 10W resistors are cheap insurance. This job used parts from Madisound. For each xo: one 3.0uF mylar (from my stash of surplus caps), three 3.9uF Carli mylar (to replace the 4.0uF NPEs) one 15uF Carli mylar (replaces 16uF NPE) two 12uF Bennic NPEs paralleled (to replace 25uF NPE) one Madisound 10 ohm 15W resistors one Erse 6 Ohm 10W resistors (from my parts box) one Madisound 5 Ohm 15W resistors (10W not available) two Eagle 16 Ohm 10W resistors (to replace 15 Ohm) Several of the values are just a tad off but within the spec tolerance. I discussed adding 0.1uF and 1.0uF caps to make the cap values exact with the owner but we agreed it would not make an audible difference. The Eagle resistors are on sale for 0.50 each and happened to be the closest value available. The Madisound 15W resistors are more than is needed, and a little large, but one consideration was to order everything from one supplier to save shipping costs (and they are also just 0.50 each). And Madisound is great! I goofed on my order on Saturday. Just phoned Monday morning and Adam took care of it! Total cost of parts for two speakers ~$50. Not bad. The next set will be essentially the same but the owner of those xo's opted for film caps for the 25uF value. More to follow...... -Kent Link to comment Share on other sites More sharing options...
