meagain Posted January 2, 2006 Share Posted January 2, 2006 It looks like we'll probably at least 'start' testing tonight. Hubby wanted to test with some gadget (I've been too sick to ask what it is). He didn't want to rely solely on ear - he wants to 'see'. Was supposed to get the Mic for this on NYE but the guy who's borrowing it was sick & didn't show. Hubby's getting the mic tonight. I think we're going to put each speaker in a mono port, then a/b them that way as ONE listening test. But first we have to ensure both speakers as they are now are on as equal a playing field as we can get them. Jeff - you said you tested with some old Steely Dan and "might" have heard a difference? Can you remind me as to what song? Hubby has some old SD around here somewhere. And where/what exactly did you hear an improvement on? Was it across all tones or just in certain high ranges, etc?

You're right on that, Dean, if you read it one way, but I meant it like she might see a positive improvement and stick with what she has found via Rick.

www.records Posted January 2, 2006 Share Posted January 2, 2006 I would think to really test out the updated xover a person would install them both and listen for a week or so to lots of different music and then decide. Just hooking one of them up for a short listen wouldn't give me a good indication of changes. Lots of changes are subtle and might take some time to realize. JMO In other words, Jeff, you really ought to give them a longer listen. Again, JMO. Quote Link to comment Share on other sites More sharing options...

I heard the 2-count and 4-count going simultaneously on the high-hat and wasn't sure if I heard it that way before - that was why I said, "maybe." After going back to the old xovers, it was there, too. Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted January 2, 2006 Author Share Posted January 2, 2006 Dean said: " I would just like to say that out of the hundreds of users who have done this -- Jeff is the FIRST to report the impact in this way." I am trying to ignore this mess, but - Yeah, what Dean said. Jeff, Please send me your old crossovers and let me test them on a spectrum analyzer and let me test your capacitors. That will not cost you anything except shipping to me. Bob Are you wanting them for your curiosity's sake? Because my curiosity is pretty settled. I'm happy with them.

BEC Posted January 2, 2006 Share Posted January 2, 2006 I guess you could call it curiosity. If they turn out to be good, they would be the first of that age (out of a few hundred) I have seen with good caps in them. Bob Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted January 2, 2006 Author Share Posted January 2, 2006 Tell you what. I'd like to keep passing on the good-will started by Rick. So, Rick, if you're okay w/me keeping your xovers while Bob checks mine, then, I could mail mine to Bob and not be out a system. Quote Link to comment Share on other sites More sharing options...
3dzapper Posted January 2, 2006 Share Posted January 2, 2006 OK. In the name of science. Rick Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted January 2, 2006 Author Share Posted January 2, 2006 All right. Thanks. Bob, how about I pay shipping to you and you pay shipping them back? Quote Link to comment Share on other sites More sharing options...
BEC Posted January 2, 2006 Share Posted January 2, 2006 Jeff, Deal! I will send you an email with my address. They would get here probably on Thursday if you send them tomorrow. About time we injected some science into this discussion. Bob Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted January 2, 2006 Author Share Posted January 2, 2006 Bob, please make sure you saw my post a couple pages back where I listed the printing on the caps of my old xovers. Just want to be sure that you saw it and couldn't determine from that alone that I've already got re-caps. Please confirm after reading it that you still want me to send them.

BEC Posted January 2, 2006 Share Posted January 2, 2006 I saw that post. Sounds like you have originals. Bob Quote Link to comment Share on other sites More sharing options...
Duke Spinner Posted January 2, 2006 Share Posted January 2, 2006 OOoooh .... Jeff's gonna get a lesson in .....ESR frankly, I couldn't belive those MR caps would deteriorate that much, without seeing some of BEC's testing Quote Link to comment Share on other sites More sharing options...
Jeff Matthews Posted January 2, 2006 Author Share Posted January 2, 2006 Yeah, Bob might come back and tell me they're shot. I cannot hear the difference, though. Might be I'll chalk it up to deafness. At least for my ears, no need to change. Bob, if you get amazed on the other hand that they're still okay, amaze us all.

I've been following this thread from the beginning (I guess I have no life). Seemed like an awfully short test. One or two songs in a quick "A/B". Not sure if Jeff pulled the speakers fromt he corners and set them side by side for a reasonably unbiased A/B or not. I applaud meagain's hubby for pulling out the test equipment to test BOTH before and after for a decent comparison. We'll see... Quote Link to comment Share on other sites More sharing options...
Deang Posted January 2, 2006 Share Posted January 2, 2006 What is 'meagain' getting ready to swap out -- and what's going in to replace it.? Quote Link to comment Share on other sites More sharing options...
meagain Posted January 2, 2006 Share Posted January 2, 2006 Dean - I currently have 1981 Klipschorns with AA's. 3dzapper's are AA's with new caps. Going to see if there's a difference. Still waiting for hubby to get home with the mic plus when he does he has another project to deal with. I suspect we might not even get to the 'swap for the new ones' till tomorrow at this point. We'll see. Sorry I'm taking so long. Quote Link to comment Share on other sites More sharing options...
BEC Posted January 2, 2006 Share Posted January 2, 2006 Jeff, Send them on out here and I will test and fully disclose all results. If your old Aerovox caps are like the fine example in this picture, I will pronounce you well and truly deaf. Most likely though, yours are better than this one.

I'm with you on your reasoning and suggestions, but I want to re-state about my perspective. My perspective is that of a non-ever-tweaker. If I don't hear it right there on the spot, and if I have to "guess-around," then, for me, it's just not too important a difference. I know that probably doesn't go for everyone. But that's sort of a rule of how I would consider myself capable of being influenced. Quote Link to comment Share on other sites More sharing options...
