colterphoto1 Posted February 10, 2015 Share Posted February 10, 2015 networks can be repaired, I've done a few pro models. I have a couple of 1132/1133's around here. Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted February 10, 2015 Share Posted February 10, 2015 Let's back up. What's broke? No hf output on one cabinet? Swap networks or drivers to determine where the failure is. Sometimes this just localizes it to a wiring termination somewhere for a really cheap fix! Quote Link to comment Share on other sites More sharing options...

Swap networks or drivers to determine where the failure is. Sometimes this just localizes it to a wiring termination somewhere for a really cheap fix!This speaker came with no networks whatsoever in either cabinet. In reading I see that it is common for them to be sold in that configuration for theater use. I'm going to use this in my garage and just wanted a passive crossover for ease of use as well as to keep the overall cost down.I also believe I will need a new diaphragm for the k-1132 because they guy I bought it from had hooked his stereo directly to the tweeter so I assume it's blown. He said he couldn't get any sound out of it :/ This guy was high as a kite when I met him. Quote Link to comment Share on other sites More sharing options...
jwc Posted February 10, 2015 Share Posted February 10, 2015 (edited) It seems to me the networks I have won't be correct for your setup. The below: file:///C:/Users/jwcullison/Downloads/KP-456-HF%20B-1%20(1).pdf is much different and much simpler than what I have. Unless somebody comes on here and provides a good rebuttal to the contrary, I think you should hold off on buying what I have. However, I would wager that the 1132 would need only little EQ with an active setup. jc Edited February 10, 2015 by jwc Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted February 10, 2015 Share Posted February 10, 2015 to test tweeter without a network, turn the bass all the way down on your system, turn volume ALL THE WAY DOWN, hook up tweeter, slowly increase volume but never much than just a peep. Hear anything? Or if you have an ohmmeter, put it across the terminals of the tweeter driver (unhooked from anything else). Should be between 6 and 16 ohms. If tweeter is burned or otherwise dead, it will usually be an open circuit. Last case - open it up and take a look see for burned areas on the voice coil or shattered diaphragm.

finallygotmyheresies Posted February 10, 2015 Author Share Posted February 10, 2015 I dug out my ohmmeter and the driver reads 6.2~6.4 so I guess its safe. Thats a nice surprise.

The big thing for me is to not throw away money on this thing and I thank you for helping make sure I don't. Quote Link to comment Share on other sites More sharing options...
jwc Posted February 10, 2015 Share Posted February 10, 2015 yes.....2 way active simple XO at 650Hz.. However, you may find that the HF may need a little EQ. Quote Link to comment Share on other sites More sharing options...
jwc Posted February 10, 2015 Share Posted February 10, 2015 yes simple active 2 way at 650Hz would be fine but there is a chance your HF might need a little EQ to your liking.... here is my 450 HF Quote Link to comment Share on other sites More sharing options...

finallygotmyheresies Posted February 10, 2015 Author Share Posted February 10, 2015 yes.....2 way active simple XO at 650Hz.. However, you may find that the HF may need a little EQ. If I use a active crossover on a single 2-way speaker could I then get away with just using a single stereo amp? For example Hi signal to right channel and Low signal to left channel. Right speaker to HF bin and Left speaker to LF bin? Seems simple, am I missing something? I have a Adcom GFA-545 I could use. Quote Link to comment Share on other sites More sharing options...
finallygotmyheresies Posted February 10, 2015 Author Share Posted February 10, 2015 However, you may find that the HF may need a little EQ. Would this be done after the crossover or are would the treble controls on a preamp handle the EQ you refer to? Quote Link to comment Share on other sites More sharing options...

Only way to really adjust what is needed without a passive....is a graphic or parametric eq. Treble probably wont address the humps with that driver on that horn Quote Link to comment Share on other sites More sharing options...
jwc Posted February 11, 2015 Share Posted February 11, 2015 Here is a little setup I had a few Years back. A little trick I figured out. The two KPT-904 (KP-450) 15" woofers in parallel have about the same measured impedance as dual K-31's (dual 12" woofers in Jubilee and KLF-30's) at the same frequencies. So I had a little mini punch with dual K31's with the KP 450 HF. I used the KP 450 LF and HF XO with the test setup. Worked great......!!!!!!
