twalkonline Posted March 28, 2012 Share Posted March 28, 2012 Have been following the earlier KP-115 thread as I, too, just picked up a KP-115. I haven't powered mine yet as it needs a couple of physical/hardware fixes. In the meantime I was wondering... Most posts about the 115 cite poor performance. According to the literature there were versions that did NOT have the internal crossover? Has anyone run one of these without the internal crossover and if so, are the results any better? Does anyone have a schematic of the crossover? I didn't trace it out, but I'm assuming it's just a 12dB/oct low pass with 6dB/oct (single cap) high pass to the HF Out and those big honkin' resistors are across the HF out for the sake of amplifier loading if nothing is connected to the HF Out. Can anyone confirm that or set me straight otherwise? Has anyone using the internal crossover made any mods that helped? The 6mH inductor in mine reads about 1 ohm dc resistance - that's easily 10% of your power sucked up by the inductor. Anyone ever replaced the inductor with one of those ultra-low resistance inductors? I'm not above doing that, but I'd like to know in advance if it's going to help before I spend more on one inductor than I spent on the sub! Colter, if you're out there (and I know you are), you said you've seen lots of these things fried. What fries and is there a common cause other than just too much power? Would appreciate any comments. Thanks. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted March 28, 2012 Share Posted March 28, 2012 with/without the crossover, they're just poopy. Asking too much of a small box. The porting is hideous. But best of luck with it, I've just never been a fan. Quote Link to comment Share on other sites More sharing options...
