Deang Posted April 1, 2014 Author Share Posted April 1, 2014 I will display my ignorance publicly - why doesn't the common probe from the meter count as a return path? Quote Link to comment Share on other sites More sharing options...
Deang Posted April 2, 2014 Author Share Posted April 2, 2014 Got it. Is this better? : ) Music is playing, but barely - the high pass is .99mfd, the dog can hear it. Quote Link to comment Share on other sites More sharing options...
Deang Posted April 2, 2014 Author Share Posted April 2, 2014 Dean, If you still have this setup, connect the input (+ and -) to an amplifier and connect the output (+ and -) to a speaker. Now measure the DC bias from A to B, C to D, E to F and G to H. I get 0.00 at all of the referenced points. Quote Link to comment Share on other sites More sharing options...
Deang Posted April 2, 2014 Author Share Posted April 2, 2014 No, it's right. The negative wire from the amp is running behind the CD player, around the driver, and then connected directly to the tab. The positive wire comes out of the amp, to the makeshift four point barrier strip on the left, then the circuit, which connects to the three point barrier strip on the right, and then to the driver. It's just like your drawing. Besides, music is playing. : ) Okay, here's the JBL circuit. Quote Link to comment Share on other sites More sharing options...

Deang Posted April 2, 2014 Author Share Posted April 2, 2014 Vandersteen uses 5 meg You told me to use 1 meg Don't give me conflicting information or I'll just just pulling numbers out of you know where.

djk Posted April 2, 2014 Share Posted April 2, 2014 (edited) I would use 1MΩ, anything high should be fine. Some brands of resistors get hard-to-find, and expensive above 1MΩ The Vandesteen 5A's use three batteries per network (and all three look to be connected in series), and they are soldered in place. This is not rational as the internal cells of the battery are not soldered. Just use a good battery holder, or be very carful if you solder to the battery. Batteries with in excess of 10 years are available. http://www.google.com/url?q=http://www.avsforum.com/t/772928/vandersteen-von-schweikerts/60&sa=U&ei=NpA7U5f1ONH8yAHKnYHQDA&ved=0CE4Q9QEwEDgU&sig2=8CP7U5Vs5gOyVIMcYIpSZg&usg=AFQjCNGeZz2ntZ5Iy6_4u82aGBLzC9jfHw Edited April 2, 2014 by djk Quote Link to comment Share on other sites More sharing options...
djk Posted April 2, 2014 Share Posted April 2, 2014 "What did you think of JW's data?" Scary, don't let just anyone see it or they would never buy a Klipsch speaker. I bought the test gear we talked about, now I need to get a laptop to install it on. 1 Quote Link to comment Share on other sites More sharing options...

Deang Posted April 2, 2014 Author Share Posted April 2, 2014 No, that would be bad, it would be like crossing the streams. If you break the ground reference, you have, according to Mark, nothing but air, which sounds really bad - or if you measure it - has no sound at all.

mike stehr Posted April 7, 2014 Share Posted April 7, 2014 The bias improves the low level detail, the quite passages are less noisy, making the detail easier to hear. I connected the batteries to my Cornwalls yesterday, and my first take with the sound is what you mention above. The lack of grain/noise brings out more detail, with a blacker background. My ears noticed the difference... My Corns sound really good, now...really good... Quote Link to comment Share on other sites More sharing options...
Deang Posted April 7, 2014 Author Share Posted April 7, 2014 (edited) Thanks Mike. I hope you don't mind, but I posted the email you sent me last night on Aletheia's Facebook page. You know what they say, easier to ask for forgiveness ... Thaddeus summed it up best: "Unrelated testers with varying levels of experience and no financial incentive or bias ... All reporting similar results." Because of the great (and consistent) feedback, I'm going production with this. I'll try to get something up on my website by this weekend. Thanks everyone.

Its awesome that 5 people like this network, but its far from unbiased. Just having Dean build it, and no financial incentive is bias enough. Just knowing what the objective is and theory can tilt the scales. Fortunately the battery bias should have no ill effects, and is relatively cheap to build. Dean, I think its neat that you have applied this to Klipsch networks, I am not sure it is necessary or will compare to your paper/oil builds, but at least you have tried something new.

CECAA850 Posted April 9, 2014 Share Posted April 9, 2014 Just having Dean build it, and no financial incentive is bias enough. I paid for mine. If I didn't like them I'd have no issues saying so. Quote Link to comment Share on other sites More sharing options...
