PrestonTom Posted September 17, 2017 Share Posted September 17, 2017 Guys: Was there ever a design or a schematic for two-way system using a K-510 horn (for instance a Jubilee crossed around 500Hz). I thought I saw one sometime ago. Thanks, -Tom Quote Link to comment Share on other sites More sharing options...
Chris A Posted September 17, 2017 Share Posted September 17, 2017 I couldn't find a passive circuit for a K-510, only active PEQs. The original settings and resulting net PEQ curve for the K-69-A on a K-510 horn are shown below for reference. There are 8 PEQs that are used: Chris Quote Link to comment Share on other sites More sharing options...
Deang Posted September 17, 2017 Share Posted September 17, 2017 Any driver that needs that much correction is a POS. 1 Quote Link to comment Share on other sites More sharing options...
PrestonTom Posted September 17, 2017 Author Share Posted September 17, 2017 My question is a simple one. Is there a schematic for a passive crossover for a two-way using the K-510. Although I appreciate the benefits of a DSP solution, that is not an option in this particular application. Regarding the notion that the horn needs "correction" is silly. It is very simple: the network needs three things 1) adjusting the gain for differences in efficiency between the tweeter and woofer, 2) attenuation at the crossover point and 3) a high frequency boost because it is a CD horn (constant dispersion). I know that you are smart enough to understand this. I assume your misleading comment about it being a POS unit simply indicates some agenda that you might have (and that I am not interested in). Please let's stay on topic. Quote Link to comment Share on other sites More sharing options...
Chris A Posted September 17, 2017 Share Posted September 17, 2017 Tom, The reason why I posted the PEQs is that Bill Waslo's XSim freeware app can calculate the on-axis response for a given passive network (that you've built up within XSim) if you've measured a driver with horn using something like DATS to record its impedance vs. frequency. It's even simpler than other graphic-based analysis packages out there--and it's free. I've got a .zma file for the K-510/K-69-A that XSim uses--in case you're interested in trying to develop your own passive schematic. If you then know what the on-axis correction PEQs are for the horn+driver (like I posted above), you can approximate a passive network that gets much closer on the first try.

PrestonTom Posted September 17, 2017 Author Share Posted September 17, 2017 Chris, Thanks. I am comfortable setting up a DSP crossover. However, I would be a fish out of water setting up an analog version. I know enough to know that it can get complicated. I was hoping someone had already done this. I thought I remembered seeing something in the past.... Quote Link to comment Share on other sites More sharing options...

moray james Posted September 18, 2017 Share Posted September 18, 2017 please count me in on being interested in that schematic. Thanks. Quote Link to comment Share on other sites More sharing options...
jwc Posted September 18, 2017 Share Posted September 18, 2017 Ok. I might be talking out of my head..... Now I question whether I'm mistaking for something else. Quote Link to comment Share on other sites More sharing options...
sootshe Posted September 18, 2017 Share Posted September 18, 2017 This may not be of use, but here's one for the K69 with the 402 horn. 1 Quote Link to comment Share on other sites More sharing options...
Schu Posted September 19, 2017 Share Posted September 19, 2017 What would change in that if one were to use a 691k? Also... that doesn't look like it's big-amp friendly. Quote Link to comment Share on other sites More sharing options...
Schu Posted September 19, 2017 Share Posted September 19, 2017 I have no idea why those graphs are attached to my post... I can not delete them Quote Link to comment Share on other sites More sharing options...
