The Dude Posted September 29, 2013 Author Share Posted September 29, 2013 Hey look if I go butterworth. I get the intersection closer, I don't know if that is what needs to be done. I figure there is probably some acoustics that will affect the crossover point. Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted September 29, 2013 Share Posted September 29, 2013 i'm catching these screen shot & your decriptions , keep 'em coming [Y] Yeah My plan is miniDSP's for the THT horn subs & then go active with my 9 channels of 2-ways controlled by the miniDSP after the subs are up & running I can see where the miniDSP's Future is all "Sunshine" so I'll need sunglasses If you get my drift [H] Quote Link to comment Share on other sites More sharing options...
The Dude Posted September 29, 2013 Author Share Posted September 29, 2013 Kind of going the same route as you. I was thinking of trying one of those amps from either crown such as the xti 1001 or the behringer inuke1000 for the sub. Behringer DCX2496 for the L/C/R. I could all ways use the minidsp down the road for my surrounds, I started with the minidsp for the cost and simplicity. I am on the computer upstairs if I get down stairs tomorrow I will post some more screen shots. Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted September 29, 2013 Share Posted September 29, 2013 I'm looking at that unit that has a class "D" plate amp for use with a THT sub that's that new 'ICE' class " D " cost wise it's about the same as seperate miniDSP & a Dayton 400 watt plate amp bi-amp both channels gets you 475 watts http://www.minidsp.com/products/plate-amplifiers/pwr-ice125 Quote Link to comment Share on other sites More sharing options...
Horatio Posted September 30, 2013 Share Posted September 30, 2013 I have been using a MiniDSP to run my Speakerlab K (uses K33E woofers), that has EV HR6040+Altec 288 top end. This is a two way configuration, and the Altec drivers give a bit more top end than the EV DH1012's I've used, enabling this to effectively be a two-way setup. The bass horns were set up along the tuning parameter lines that Greg Oshiro has done using a different crossover. I have found those frequencies and gains to work reasonably well, although I had to hand tune some of the gains for my room. I run the LeCleach butterworth configuration on the filter. Very pleased with this. Run 100W Mosfet monoblocks on the bottom, SE84 SET (2w) on the top. I am not necessarily golden-eared, but this arrangement gives a system that images unlike any horn system I've ever listened to. Quite pleased. Be careful with the MiniDSP, and turn your amp gains way down. While messing around with my unit during setup, I was able to introduce transients into the horns that actually took pictures off the wall in my livingroom (not to mention scaring the he** out of me in the process), Approach with care and caution, and you will be rewarded. I keep my unit powered on 24-7, because the management of the turn on and shut down of my system requires a bit of care (tube amps don't turn off instantly). So, I sequence the power to the system using one of the power sequencer units often used in pro sound. Have fun! Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 2, 2013 Author Share Posted October 2, 2013 Horatio, would you mind sharing your settings. I know they would be different from mine as we are using different drivers/horns etc. But may give me something to look at. Fast here is some more screen shots for you.

The Dude Posted October 2, 2013 Author Share Posted October 2, 2013 None of these settings may be idea but just the latest I was playing with. Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 2, 2013 Author Share Posted October 2, 2013 One of the things Dave said in Gregs tri amping post, is something along the ways of work on the peaks as the dips may be a room mode. I take it room modes must be tougher to get rid of then peaks. Which makes since, in a way. Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 3, 2013 Author Share Posted October 3, 2013 Using REW, bass bin only, from 40-500hz Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 3, 2013 Author Share Posted October 3, 2013 HP640 and Faital hf 200 alone Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 3, 2013 Author Share Posted October 3, 2013 And of coarse all together. Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 3, 2013 Author Share Posted October 3, 2013 I remember when I check my levels the hp640 was alot higher then the bass bin so I dropped it down to be more accurate. Quote Link to comment Share on other sites More sharing options...
Greg Oshiro Posted October 4, 2013 Share Posted October 4, 2013 Those measurements look very promising. Where is the mic located? How about a 20Hz to 2KHz sweep of just the LF including the crossover filter? dB-SPL and phase. How much amplifier power is available for the LF?

The Dude Posted October 4, 2013 Author Share Posted October 4, 2013 The mic is located the about 3' from the center of the horn. I will have to try tomorrow, for some reason REW is not responding on my laptop. So I am clear, you want me to leave the crossover filter inputted. Run the frequency sweep from 20hz to 2khz.. Amplifier power would be 50 watts rms from my MC2505 should I get a different amp and re run everything. Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 23, 2013 Author Share Posted October 23, 2013 So before I figured something out, I moved the Klipshorns to garage(for multiple reasons). But I figured out the auto eq tool, this is very helpful for equing things, which I would have figured this out before I moved them. Well if the sell never goes through by the time I get my basement finished, then I will get back at it. Greg thanks for all your help and offers. Like I said if I get back at this project I will drop you a line. But for now I have the listening room simplified so I can just listen to music.
