ZombieWoof Posted September 9, 2012 Share Posted September 9, 2012 Dave have you considered the tang band w8-1772 ? http://www.parts-express.com/pe/showdetl.cfm?partnumber=264-893 they use it in the Transcendent Sound DYI speaker . he uses a resistor to tame the high end those have the Neodymium magnets in them http://www.transcendentsound.com/Transcendent/DIY_Speakers.html Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 9, 2012 Share Posted September 9, 2012 Dave have you considered the tang band w8-1772 ? I have looked at the TB, looks like a fine driver but is near double the cost of the Dayton or the Audio Nirvana. Dave Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 11, 2012 Share Posted September 11, 2012 Built another pair of boxes for myself. I wanted to take some measurements. Although the new box was a signifigant improvement over the monitor design, I suspected a contour network was in order. Quote Link to comment Share on other sites More sharing options...

Guest David H Posted September 11, 2012 Share Posted September 11, 2012 Made a short field trip to Johnny 5's for some listening impressions. Bass sounds good, hf is hot. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 11, 2012 Share Posted September 11, 2012 Response taken on my ipod for quick reference. Pay no attention to the LF response, not accurate with my portable mic. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 11, 2012 Share Posted September 11, 2012 Enter the contour network. Currently I am still fine tuning the network with a selection of inductors and resistors, however the 1.5mH inductor with a 12.5R is doing a fair job.

Guest David H Posted September 11, 2012 Share Posted September 11, 2012 Simple but effective network for taming full range drivers. Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted September 11, 2012 Share Posted September 11, 2012 very cool. having a bit of trouble with drooling on my keyboard. [] my wife is going to bring me a bib! Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 12, 2012 Share Posted September 12, 2012 Thanks Dee. These are coming along nicely, however require a bit of tuning still. Justin Webber just sent his set out for paint, as I understand the main box will be fire engine red and the base piano black. I suspect these will look very nice.

Daddy Dee Posted September 12, 2012 Share Posted September 12, 2012 Dave, What is your take on the networks and their impact on the sound. Their purpose is to compensate for some shortcomings of the full range drivers. Could you say more about that? Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 13, 2012 Share Posted September 13, 2012 Dave, What is your take on the networks and their impact on the sound. Their purpose is to compensate for some shortcomings of the full range drivers. Could you say more about that? I would have to say the networks benefits outweigh their loses by a signifigant margin. The full range drivers although amazing have a rising response that needs addressing. What I have noticed working with the contour networks is that larger gauge inductors seem to have the largest impact on the sound. I tried AWG 18 and AWG 15 inductors of several different values, the AWG 18 seemed to degrade the sound quality. I suspect this may be due to the increased ESR.

bracurrie Posted September 15, 2012 Share Posted September 15, 2012 What do you mean by "rising response" and what is ESR? Sorry to be so non technical. Brad Quote Link to comment Share on other sites More sharing options...

justinsweber Posted September 23, 2012 Author Share Posted September 23, 2012 In red :-) I tried a contour network, I they seemed more alive without... Maybe not as refined, but feeling more present. Forgot to snap pics with the drivers in place. The minimonitors are really nice from 60hz on up but its obvious that the cabs are the limiting factor. The same AN8 in dave's cab shows that there are limits to the drivers too. The cab allows the drivers to stretch down much much lower. As I already have 3 large speakers, Im keeping my mini monitors, but my budy will be taking the Full size cabs from me in time. He was impressed by the size of the sound stage and just how airy they sounded. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted September 23, 2012 Share Posted September 23, 2012 Those look nice assembled with the stands. I need to try the FR with an active crossover and see how it sounds. I had hoped to get to that this weekend, but my new CNC machine arrived and ate up most of my weekend. Quote Link to comment Share on other sites More sharing options...
