Number 9 Posted December 13, 2004 Share Posted December 13, 2004 I've even heard some people say caps are subject to the magnetic fields of the woofer, which is not good too. I don't know ...maybe that's BS. Perhaps this explains why some speaker manufacturers have gone to putting even passive xovers external to the speaker monkey coffin. For example, the Living Voice Avatar OBX uses a totally external xover. No need for hot melt then. In fact, I think this is exactly what I may do one day with my Fortes.

rockbobmel Posted December 14, 2004 Share Posted December 14, 2004 Hi Dean, I have a few questions. 1) is the solder critical? I have some .032 rosin core 60/40 solder on hand. 2) could I use the tip of a small round rat tail jewelers saw for reaming the holes bigger instead of drilling them? I am afraid of twisting off the foil on the board. Thanks, Bob Melnik Quote Link to comment Share on other sites More sharing options...
STL Posted December 14, 2004 Share Posted December 14, 2004 chazklf, It's not a matter of watts -- but rather sound quality. Quote Link to comment Share on other sites More sharing options...

Deang Posted December 14, 2004 Author Share Posted December 14, 2004 It will sound cleaner, smoother, and more open. No hash/grain, and less harsh when driven hard. Bob, I'm sending some WBT high content silver solder with the parts. As far as the holes go -- let common sense prevail. If you have a way of doing it that seems easier or better for you -- try it. If you happen to lift some foil, don't sweat it -- just scratch through the coating down to the copper (the whole PCB is copper) next to the hole. Bend your lead over onto the copper surface and solder. Quote Link to comment Share on other sites More sharing options...
chazklf Posted December 16, 2004 Share Posted December 16, 2004 what exactly do i need can most of it be gotten from radio shack? Quote Link to comment Share on other sites More sharing options...
STL Posted December 17, 2004 Share Posted December 17, 2004 Are you joking? You might be able to get one or two things there (and even that is a big maybe). Since you are going to have to mail/online order anyhow you might as well get to know www.partsexpress.com . Their selection and pricing blows away Radio Shack!

Deang Posted December 17, 2004 Author Share Posted December 17, 2004 I covered basic tools and provided the link to partsexpress at the beginning of thread. Any person interested in doing this kind of thing has to self-motivate, and be willing to do some homework. Due to the subject of DIY and soldering coming up in another thread, I went out last night with Google and in less than 30 seconds found a half dozen sites providing on-line tutorials. There is no shortage on the web with information from everything to anything -- use it. Quote Link to comment Share on other sites More sharing options...

rockbobmel Posted December 23, 2004 Share Posted December 23, 2004 This is my progress on my Forte IIs. Are these right? I think I got the caps OK, but does the black resistor (40ohm) replace the white 39 ohm one on the board? Also is the polarity OK on the caps.

Deang Posted December 24, 2004 Author Share Posted December 24, 2004 Hi Bob, So far so good. Attached is the Forte II schematic. Doesn't look like you need to worry about replacing the 39 ohm resistor with the 40.2 ohm Mills I sent. The tolerance on that 39 ohm resistor is + or - 10%, and if you were to measure it you would see it comes in a bit past 39.5 -- which is why Klipsch probably used it. The Mills is within 1%, and they're all typically dead on. It doesn't matter which way you situate the caps, even though some try to say it does. You're fine. Looks good!

rockbobmel Posted December 24, 2004 Share Posted December 24, 2004 Thanks Dean, What a Difference!! The speakers sound much better now. Before,I had some anti skid material hanging in front of the horns to calm down the harshness. Now they sound really sweet. Really alive! HIGHLY RECOMMENDED!

3dzapper Posted December 24, 2004 Share Posted December 24, 2004 Proffessor Dean, Does this pass? The OE caps are to the left. I know, those aren't "designer" caps. These are KG-4.5s for cryin' out loud! I had already done the other one months ago and finished the internal mods to the enclosure yesterday. I'll take pics of the mods on this, second, one and if they sound markedly better, I'll post a thread. (If they don't I'll never tell! ) Rick Quote Link to comment Share on other sites More sharing options...
Deang Posted December 25, 2004 Author Share Posted December 25, 2004 What are those things Rick? Are they polypropylene's? Hey, if you have access to non-"audiophile", mil-spec polypropylene's I wanna know about 'em!! Quote Link to comment Share on other sites More sharing options...

Deang Posted December 25, 2004 Author Share Posted December 25, 2004 Really. I'm not much of an ebayer. That place is a cluster****. I guess I need to learn how to navigate through that mess. Thanks Mike. Quote Link to comment Share on other sites More sharing options...
mike stehr Posted December 25, 2004 Share Posted December 25, 2004 I've been trained by a retired EE audio hobby lunatic that has nothing better to do than lurk Ebay for his audio "sickness". He sells quite a bit of stuff too. I agree, it is drag. If I really want or need something I go for it, mostly for parts. When you hit a auction of interest, rap with the seller a couple times before the auction ends, or before you bid. They don't reply, selah... They seem to have a bad attitude, see ya! If it seems shaky, RUN! Sometimes they are very helpful, and may even work with you obtaining bulk at a good price, who knows..... I met that EE through Ebay.
